The effect of a three month,low-load- high-repetitions group-based exercise program versus pilates on physical fitness and body composition in inactive women

ObjectiveBoth low-load-high-repetitions (LLHR) and Pilates programs constitute popular forms of exercise, accompanied by health benefits for the participants involved. Notably, the effect of such programs on aerobic fitness is still controversial. The aim of this study was to examine the effects of both programs on physical fitness and body composition on previously inactive adult women.MethodsTwenty-six women (39.8 ± 9.1y) were assigned to a LLHR program, and sixteen women (39.1 ± 12.2y) were assigned to a Pilates program. Both programs were performed in a group setting, 3 times per week for 3 months. Aerobic fitness, flexibility, handgrip strength and lower extremities explosiveness were assessed by a battery of field testing. Total body fat and trunk fat levels were assessed by bioelectrical impedance analysis. Heart rate response during exercise was recorded once every month by using a telemetry system.ResultsAerobic fitness, lower extremities explosive power, left arm handgrip strength and body composition significantly improved in the LLHR group; while flexibility significantly improved only in the Pilates group, following the intervention period (p < 0.05). LLHR was superior to the Pilates program in improving aerobic fitness and body composition; whilst Pilates was superior in improving flexibility (p < 0.05).ConclusionLLHR group-based exercise programs may improve various aspects of physical fitness, including aerobic fitness, in inactive adult women. This medium-intensity form of exercise is generally well tolerated and might be used as an option for women who cannot perform training on higher intensities. In contrast, the Pilates program failed to improve physical fitness-related parameters except flexibility levels.     

Multicomponent exercise training is effective in improving health and behavior indicators in Brazilian elderly women: A non-randomized trial

Objective: The aim was to evaluate the effects of a supervised 12-week Multicomponent exercise training on elderly women health and behavior indicators. Methods: Anthropometric characteristics and body composition, functional capacity, sedentary behavior, physical activity level and biochemical profile were evaluated in the control group (67.2 ± 5.2 years, n = 14) and in the experimental group (67.4 ± 6.1 years, n = 41). The experimental group were composed by 41 elderly women who performed 12 weeks of Multicomponent exercise training involving strength, aerobic, flexibility and balance exercises. The inclusion criteria for the study were women aged 60 years or more and presentation of a medical certificate authorizing the practice of physical exercise. Results: Maintenance of anthropometric characteristics and body composition was observed in both groups (p > 0.05). There was an improvement in aerobic capacity, lower and upper limb strength in the experimental group (p < 0.01), while the control group showed a reduction in aerobic capacity, lower limb strength, agility and dynamic balance (p < 0.01), as shown in Fi.gure 3. There was a reduction in sedentary behavior and an increase in physical activity level in experimental group (p < 0.05), but not in control group. Experimental group showed an improvement in glucose levels and lipid profile (p < 0.01). Conclusion: Multicomponent exercise training was efficient to improve health and behavior indicators of the elderly women.     

Core muscle activation during Pilates exercises on the Wunda chair

ObjetivesThe Pilates method, developed by Joseph Pilates (1886–1967), has been widely used to improve trunk stability, muscle flexibility and strength, physical fitness, and body awareness. To measure the electromyography of four trunk muscles during three Pilates exercises carried out of the wunda chair.Desingcross-section study.MethodsSixteen women participated in this study with a height and body weight of 1.64 ± 0.04 m and 58.7 ± 7.4 kg, respectively, and a mean age of 27.6 ± 3.7 years. Rectus abdominis (RA), internal oblique (IO), longissimus (LO), and multifidus (MU) muscles was evaluated by electromyographic (EMG) tests activity during three Pilates exercises: going up front (GF), mountain climb (MC), and swan (SW). EMG was normalized and expressed in the time domain, by the RMS.ResultsThe highest EMG values concerning the four muscles were observed for the MC exercise, followed by GF and SW (ANOVA: p = 0.0001, p = 0.04, p = 0.0002, and p = 0.0013, respectively). Our results show that the three Pilates exercises could recruit all the muscles, with a moderate activity intensity. The ANOVA; p < 0.05 showed significant difference between the muscles, concerning SW (p = 0.0002).ConclusionOur results show that the three Pilates exercises could recruit all the muscles, with a moderate activity intensity.     

Heart rate variability measures for prediction of severity of illness and poor outcome in ED patients with sepsis

IntroductionThis study evaluates the utility of heart rate variability (HRV) for assessment of severity of illness and poor outcome in Emergency Department (ED) patients with sepsis. HRV measures evaluated included low frequency (LF) signal, high frequency (HF) signal, and deviations in LF and HF signal from age-adjusted reference values.MethodsThis was a prospective, observational study. Seventy-two adult ED patients were assessed within 6 h of arrival.ResultsSeverity of illness as defined by sepsis subtype correlated with decreased LF signal (sepsis: 70.68 ± 22.95, severe sepsis: 54.00 ± 28.41, septic shock: 45.54 ± 23.31, p = 0.02), increased HF signal (sepsis: 27.87 ± 19.42, severe sepsis: 44.63 ± 27.29, septic shock: 47.66 ± 20.98, p = 0.01), increasingly negative deviations in LF signal (sepsis: 0.41 ± 24.53, severe sepsis: −21.43 ± 30.09, septic shock −30.39 ± 26.09, p = 0.005) and increasingly positive deviations in HF signal (sepsis: −1.86 ± 21.09, severe sepsis: 20.07 ± 29.03, septic shock: 23.6 ± 24.17, p = 0.004). Composite poor outcome correlated with decreased LF signal (p = 0.008), increased HF signal (p = 0.03), large negative deviations in LF signal (p = 0.004) and large positive deviations in HF signal (p = 0.02). Deviations in LF and HF signal from age-adjusted reference values correlated with individual measures of poor outcome with greater consistency than LF or HF signal.DiscussionAccounting for the influence of age on baseline HRV signal improves the predictive value of HRV measures in ED patients with sepsis.     

The effect of postintensive care syndrome on the quality of life of intensive care unit survivors: A secondary analysis

BackgroundDespite increasing interest in postintensive care syndrome and the quality of life of intensive care unit survivors, the empirical literature on the relationship between these two variables is limited.ObjectivesThis study aimed to examine whether postintensive care syndrome predicts the quality of life of intensive care unit survivors.MethodsWe analysed secondary data, which were collected as part of a larger cross-sectional study. The participants were recruited from six health institutions in Korea. The data of 496 survivors who had been admitted to an intensive care unit for at least 48 h during the past year were analysed. They responded to measures of postintensive care syndrome and quality of life.ResultsThe participants' mean physical and mental component summary scores (quality of life) were 40.08 ± 8.99 and 40.24 ± 11.19, respectively. Physical impairment (β = ?0.48, p < 0.001), unemployment (β = ?0.19, p < 0.001), low income (β = ?0.11, p = 0.004), older age (β = ?0.08, p = 0.039), and cognitive impairment (β = ?0.11, p = 0.045) predicted lower physical component summary scores. Mental (β = ?0.49, p < 0.001) and cognitive impairment (β = ?0.14, p = 0.005) and low income (β = ?0.09, p = 0.014) predicted mental component summary scores.ConclusionsThe participants reported poor physical and mental health–related quality of life. Postintensive care syndrome, unemployment, low income, and older age were the main predictors of poor quality of life. In addition, postintensive care syndrome was a stronger risk factor for poor quality of life than demographic characteristics and intensive care unit treatment factors.     

Pilates and telomere dynamics: A 12-month longitudinal study

Telomeres are dynamic structures that appear to be positively influenced by healthy lifestyle factors such as exercise. Pilates is an increasingly popular exercise modality that is reported to exert beneficial physiological effects in the body, although the cellular mechanisms are poorly understood. The aim of the present study was to investigate the influence of Pilates exercise on telomere length. This longitudinal study followed experienced female Pilates practitioners (n = 11, 50.8 ± 7.5 years) and healthy age- and sex-matched sedentary controls (n = 11, 49.3 ± 6.1 years) over a 12-month period. Leukocyte telomere length was quantified using qPCR. Circulatory inflammatory markers, mRNA gene expression, body composition, physical performance, and mental well-being were also assessed. Telomere length was comparable between Pilates practitioners and controls at baseline (Pre) and 12-months (Post) (p > 0.0125). Pilates practitioners displayed enhanced mRNA gene expression of antioxidant enzymes (SOD2 and GPX1), and lower body fat percentage and visceral fat rating, compared with sedentary controls (p < 0.0125). Over the 12-month longitudinal period, Pilates participants significantly increased dynamic balance (p < 0.05). In conclusion, long-term Pilates participation does not appear to influence telomere length. Nonetheless, Pilates exercise appears to increase antioxidant enzyme gene expression, effectively manage body composition, and improve dynamic balance.     

The effects of a sensory stimulation intervention on psychosocial and clinical outcomes of critically ill patients and their families: A randomised controlled trial

ObjectivesTo explore the effectiveness of a sensory stimulation intervention on intensive care unit patients' psychosocial, clinical, and family outcomes.DesignA prospective, assessor-blind, parallel-group randomised controlled trial.SettingA surgical intensive care unit of one tertiary hospital in Guangzhou, mainland China.InterventionParticipants in the intervention group received a daily 30-minute auditory and visual stimulation session starting from recruitment and for a maximum of seven days while in the intensive care unit.Measurement and main resultsOne hundred fifty-two patients and family caregiver dyads were recruited. Patients in the intervention group showed lower total scores of post-traumatic stress disorder (21.92 ± 6.34 vs 27.62 ± 10.35, p = 0.001), depressive symptoms (3.76 ± 3.99 vs 6.78 ± 4.75, p = 0.001) and delusional memories (0.47 ± 0.92 vs 0.82 ± 1.23, p = 0.001) collected immediately post-intervention than those in the control group, while not on depressive symptoms at one-month post-intervention (3.32 ± 4.03 vs 3.28 ± 3.77, p = 0.800). Sensory stimulation did not significantly impact patients' unit length of stay and 30-day mortality (all p > 0.05). For family outcomes, family caregivers in the intervention group had greater satisfaction with care (127.12 ± 14.14 vs 114.38 ± 21.97, p = 0.001) and a lower level of anxiety (28.49 ± 6.48 vs 34.64 ± 7.68, p = 0.001) than family caregivers in the control group.ConclusionsSensory stimulation may benefit patients' and family caregivers' psychological well-being, and further well-designed multi-centre clustered randomized controlled trials could be considered to strengthen the evidence.     

Dissimilar perceptual response between trained women and men in resistance training to concentric failure: A quasi-experimental study

PurposeThis study compared sex-related affective responses during resistance training performed to concentric failure.MethodsThe study was a non-randomized trial (quasi-experimental study). Well-trained young participants were allocated into two groups according to sex (Women, n = 7, 21.1 ± 6.0 years, 57.6 ± 5.0 kg; and Men, n = 7, 28.3 ± 5.7 years, 88.3 ± 11.4 kg). Participants visited the laboratory three times: 1) 12-repetition maximum; 2–3) resistance training to concentric failure sessions. Perceptual measures were assessed before, during, and immediately after the resistance training sessions. The following were assessed: a) rating of perceived exertion for effort (RPE-E) and discomfort (RPE-D), b) feeling scale, c) physical activity affect scale (PAAS), d) felt arousal scale, and e) physical activity enjoyment scale (PACES).ResultsHigh levels of RPE-E and RPE-D were reported without between-groups differences (p > 0.218). Women reported a reduction in the feeling scale (p = 0.001) whereas men did not (p > 0.680). Larger effect sizes were observed for women compared to men in the felt arousal scale and PAAS (negative affect and fatigue). Feeling scale and felt arousal scale data plotted in a circumplex model of affect indicated a transition to high-activation and unpleasant-affect only for the women. There was good reliability between results from sessions 1 and 2.ConclusionsTraining to concentric failure resulted in negative changes in affective perceptual responses only for women. This type of training should be used with caution since it may change the affect perception and reduce training adherence in women. Further studies are needed using larger sample sizes, different resistance-training exercises, and diverse training methods.     

Effect of myofascial release on lower limb range of motion,sit and reach and horizontal jump distance in male university students

ObjectiveEvaluate the effects of Myofascial release (MR) on lower limb ROM, sit and reach and horizontal jump distance in male university students.Study designQuasi-experimental study.BackgroundMR is a technique that aims to stretch fascia to increase range of motion (ROM), relieve pressure points and improve performance. However, there is limited evidence of its actual effects on flexibility and physical performance.MethodsTwenty-one uninjured, male university students received MR (11 on the first session and the other 10 on the second session 24 h later), completed lower limb ROM assessments, the sit and reach and the horizontal jump tests in a randomized order. MR was performed before the tests with a myofascial stick in the anterior and posterior aspects of the right and left thigh and calf muscles. Each muscle group was massaged for 90 s, totaling 9 min of MR. The testing conditions with MR and without MR were compared using Student t-tests and the effect sizes (ES) were calculated.ResultsThere were no significant differences between the testing conditions on horizontal jump distance. However, the sit and reach distance (28 ± 9 vs. 32 ± 9 cm, p = 0.001; ES = 0.44), left hip extension (10 ± 2 vs. 8 ± 2°, p = 0.006; ES = 1.00) and left plantar flexion (36 ± 7 vs. 39 ± 7°, p = 0.044; ES = 0.43) were higher with MR.ConclusionsMR increased sit and reach distance, left hip extension and plantar flexion, but it did not affect horizontal jump distance in uninjured, male university students.     

Effects of myofascial release of the ankle plantar flexors on static postural balance of young men: A randomized clinical trial

BackgroundMyofascial release (MR) has been widely used in sports and clinical environment. There are studies that have already evaluated the effect of MR on postural control, however, the data found are inconclusive.ObjectivesInvestigate the effect of MR on ankle plantar flexor muscles over static postural balance.MethodSixty-five young men were randomized allocated into one of three groups: 1) MR group (n = 25, Myofascial Release); 2) Sham (n = 25, fake intervention); or 3) Control group (n = 15). Both MR and Sham techniques were applied during 5 min in the ankle flexors of each leg. The bipodal static postural balance test was performed before and 2 min post each intervention on a force plate with eyes closed during the test. All subjects performed 3 sets of 30-s with 1 min of rest. Mean values to the center of pressure velocity (COPvel) was used for analysis.ResultsThe bipodal balance test showed that there was no significant difference between groups (p > 0.05), but there was a significant time effect (p < 0.05). A significant decrease (p < 0.05) in post-test COPvel (cm.s⁻¹) values (sham 4.9 ± 1.2; MR 4.5 ± 0.6; CON 4.22 ± 0.8) was found when compared to values of pre-test (sham 5.3 ± 1.0; MR 5.0 ± 0.8; CON 4.94 ± 1.3) for all groups.ConclusionsThe results demonstrated that MR performed on ankle flexors did not affect static postural balance in young man. This study is a clinical trial (Register Number: RBR-48k5jm).     

Cardiorespiratory and metabolic demand of the 6-minute pegboard and ring test in healthy young adults

ObjectiveTo determine the cardiorespiratory and metabolic demand of the Six-Minute Pegboard and Ring Test (6PBRT) in healthy young adults and its association with maximal arm cycle ergometer test (arm CET).MethodsVolunteers were randomized to performed the 6PBRT test or arm CET. The second test was performed after 48 h. Oxygen consumption (VO₂), heart rate (HR), dyspnea and upper limb fatigue were assessed during the tests. Demographic data, body composition, level of physical activity, arm strength and endurance were also evaluated.ResultsDuring 6PBRT, VO₂ values increased from 5.8 to 11.1 mL kg⁻¹.min⁻¹ (p < 0.001). VO_2peak, HR _Mean and HR_max at 6PBRT were 47.2% and close to 65% respectively of those achieved during the arm CET. There was a positive correlation between the score on 6PBRT and VO_2mean and VO_2peak achieved at arm CET (r = 0.268; p = 0.003 and r = 0.247; p = 0.046 respectively). No correlation was found between the HR_mean, HR_peak, level of physical activity or strength with 6PBRT (p > 0.05). Handgrip endurance had a positive correlation with score on 6PBRT (r = 0.237; p = 0.054). Body Mass Index, body fat and fat mass were negatively correlated with the score on 6PBRT (r = 0.301; p = 0.014, 0.329; p = 0.007 and r = 0.427; p = 0.001).ConclusionsThe 6PBRT test showed a moderate cardiorespiratory and metabolic demand in healthy individuals in comparison of arm CET. BMI, body fat and fat mass correlated with the score on 6PBRT.     

Dynamic changes in liver function after transjugular intrahepatic portosystemic shunt in patients with cirrhosis

PurposeTo evaluate the dynamic changes in liver function after transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with cirrhosis and to explore its association with clinical outcomes.MethodsThis retrospective study included patients who underwent TIPS between August 2016 and December 2020. Liver function was primarily evaluated using the model for end-stage liver disease (MELD) score, which was analyzed at baseline, 1 week, 1 month, 3 months, 6 months, and 12 months using one-way repeated measures ANOVA. The Kaplan-Meier method, log-rank test, and multivariate analysis were used as appropriate.ResultsIn total, 235 patients were included in this study. The MELD score was significantly higher at 1 week (11.8 ?± ?3.1 vs 13.5 ?± ?3.5, p ?< ?0.05) and 1 month (11.8 ?± ?3.1 vs 13.2 ?± ?4.6, p ?< ?0.05) than the baseline level and recovered at 3 months (11.8 ?± ?3.1 vs 11.9 ?± ?3.9, p ?> ?0.05). At 12 months, the MELD score was higher than the baseline level (11.8 ?± ?3.1 vs 12.4 ?± ?3.2, p ?< ?0.05). Patients with a recovery of the MELD score (n ?= ?151) at 3 months had a lower probability of overt and severe HE (log-rank p ?= ?0.015 and p ?= ?0.027, respectively) than those without recovery (n ?= ?84). Logistic regression analysis revealed that albumin (odds ratio [OR], 0.926; 95% confidence interval [CI], 0.863–0.992; p ?= ?0.029) and platelet count (OR, 0.993; 95% CI, 0.987–0.999; p ?= ?0.033) were independent predictive factors for non-recovery of the MELD score at 3 months.ConclusionsLiver function after TIPS creation showed a trend of deterioration at first, followed by recovery. Recovery of liver function at three months was associated with reduced overt and severe HE.     

Improvement of quality of life and postural balance of institutionalized elderly people undergoing to a treadmill walking training

IntroductionInstitutionalized older adults have fewer opportunities to participate in daily living activities and tasks in an independent manner, with greater deleterious effects on the physiological losses inherent to aging and with increased gait and balance impairment compared to community-dwelling older adults. The use of a treadmill for rehabilitation, with or without partial weight support, has been studied in different groups, but not on institutionalized older adults.ObjectivesTo assess the effects of a treadmill walking program on the postural balance and quality of life of institutionalized older adults.MethodsThirty-seven institutionalized older adults: intervention group (n = 23, 75.7 ± 7.8 years) and control group (n = 14, 78.9 ± 10.2 years). A total of 10 weeks of treadmill walking, twice a week (intervention group) vs. no training (control group). Postural balance was assessed by the Tinetti test, 6-min walk test (6MWT), and 10-m walk test and Quality of life with the WHOQOL-Bref questionnaire.ResultsSignificant improvement was observed in balance parameters (6MWT distance: p < 0.001; gait speed 6MWT: p < 0.001; gait speed 10MWT: p < 0.001; Tinetti scale: p = 0.001), and in the physical (p = 0.01), psychological (p = 0.002), self-assessed quality of life (p = 0.01) and overall quality of life domains (p = 0.002).ConclusionsTreadmill walking program had positive effects on the postural balance and quality of life of institutionalized older adults.     

Pilates method on pulmonary function and range of motion after coronary artery bypass grafting: A clinical trial

IntroductionCoronary artery bypass grafting (CABG) can compromise pulmonary function and range of motion (ROM) of the shoulder and knee joints due to median sternotomy and saphenectomy, the Pilates method being a strategy for reducing loss.ObjectiveTo evaluate the effect of applying the Pilates method on pulmonary function and ROM in patients undergoing CABG.Methodology: This is a clinical trial. Patients were evaluated preoperatively at discharge from the hospital for shoulder flexion and abduction and knee flexion-extension. In addition, vital capacity(VC), maximum inspiratory pressure(MIP), expiratory pressure(MEP) and peak expiratory flow(PEF) were evaluated. Upon discharge from the Intensive Care Unit (ICU), they were divided into a control group(CG) that received conventional assistance and Pilates(PG) was increased with Pilates method techniques.Results40 patients were analyzed, 25 were men(61%), with a mean age of 66 ± 7 years. At the end, the left shoulder abduction in the CG was 105±9vs115 ± 8 in the PG(p = 0.03), the right shoulder abduction in the CG 104 ± 11vs116 ± 10 in the PG(p < 0.001) and right knee flexion in the CG 78 ± 13vs92 ± 9 in the PG(0.002). In relation to MIP, the CG had a loss of 32 ± 8 while the PG 18 ± 10cmH2O(p < 0.001), the worsening MEP was 31 ± 9(CG)vs29 ± 11cmH2O(PG)(p = 0.53), the VC in the CG reduced 8±9vs6±8 in the PG(p = 0.23) and the PEF reduced 107 ± 5 in the GCvs83 ± 88 in the PG(p = 0.09).ConclusionIt is concluded that the Pilates method decreased the loss of ROM and maximum inspiratory pressure in patients undergoing coronary artery bypass grafting.     

Anti-NR2 glutamate receptor antibodies as an early biomarker of cerebral small vessel disease

ObjectivesCerebral small vessel disease (SVD) associated with age and vascular risk factors is one of the leading causes of cognitive disorders as well as ischemic and hemorrhagic strokes. The pathogenesis of this disease has not been fully understood yet. The previously established association of the antibodies against the NR2 subunit of the NMDA receptor (NR2ab) with the mechanisms of SVD such as ischemia and blood–brain barrier (BBB) disruption, might suggest their importance in the brain damage.Design & methodsWe studied the NR2ab serum level in 70 patients (45 females, 61.1 ± 6.3 y.o.) with different severity of cognitive impairment and MRI features of SVD and 20 healthy volunteers (12 females, 58.5 ± 6.4 y.o.).ResultsThe elevated level of NR2ab was associated with subjective cognitive impairment (SCI) (p = 0.028) and mild cognitive impairment (MCI) (p = 0.017), Fazekas grade (F) 2 (p = 0,002) and F3 (p = 0,009) of white matter hyperintensities (WMH) and the numbers of lacunes in the cerebral white matter (less than 5) (p = 0,039).ConclusionThe detected increase in serum NR2ab level in patients with SCI, as well as the minimal amount of white matter lacunes, is most likely caused by hypoxia-induced endothelial damage in the early stage of SVD. Normal NR2ab values in patients with F1 WMH, the increased NR2ab level in patients with F2 and F3 WMH and those with the minimal number of lacunes can indicate that NR2bs are involved in diffuse brain damage due to hypoxia-induced loss of BBB integrity.     

Efficacy of foam rolling with additional vibration stimulation on the mobility of the thoracolumbar fascia. An observational study

IntroductionObservations show that foam rolling improves joint movements. Likewise, it can be stated that a vibration stimulation of the tissue leads to improved joint mobility.MethodThis study investigates whether the combination of foam rolling and vibrations (31 Hz) can influence the sliding of the thoracolumbar fascia more effectively than normal foam rolling. 45 subjects participated in the study and were divided into a foam roll with additional vibration group (FRV), a foam roll group (FR) and a control group (CG). The intervention groups rolled out the gluteal muscles, the lateral trunk and the upper and lower back. Mobility measures were taken pre and post the respective intervention. Subsequent cross correlation software analysis quantified the sliding of the fascia and calculated its shear strain mobility (SSM).ResultsThe sliding of the thoracolumbar fascia improved significantly within the FRV by 2.83 mm (SD ± 1.08/p < .001), in the FR by 0.96 mm (SD ± 0.43/p < .001) and in the CG decreased the sliding by 0.1401 mm (SD ± 0.28/p = .076). The fascia/fascia SSM increased in the FRV by 22.61% (SD ± 15.64/p < .001), in the FR by 11.41% (SD ± 20.38/p = .056) and in the CG decreased the SSM by 0.9473% (SD ± 11.35/p < .751). The lumbar movement increased in both intervention groups, but showed no significant result.ConclusionThe use of a foam roll with additional vibration and standard intervention have increased thoracolumbar fascia sliding and lumbar movements. The improved shear strain mobility can be attributed to the multi-activity of mechanoreceptors, such as Pacini- and Ruffini-Bodies.     

Detraining period of the PILATES method on functional capacity of elderly women with type 2 diabetes: A randomized clinical trial

IntroductionThe aim of this study was to verify the effects of a 4-week detraining period on the functional capacity of elderly women with type-2 diabetes (T2D) after 12 weeks of a PILATES training program.MethodsTwenty-two individuals with T2D were randomly allocated into two groups: CONTROL (n = 11; 67.5 ± 6.3 years; 154.7 ± 6.1 cm; 73.5 ± 6.1 kg; calorie intake: 1487.5 ± 360.6 kcal/day) and PILATES (n = 11; 65.5 ± 5.5 years; 155.0 ± 4.5 cm; 66.2 ± 5.4 kg; calorie intake: 1289.3 ± 385.0 kcal/day). The PILATES group participated at a 12-week PILATES program at moderate intensity, 3x/week with each session lasting 60-min. The functional capacity was evaluated in the baseline (PRE), after 12-weeks (POST) and 4-week detraining period (4W_DT). The general index of functional capacity (GI_FC) was calculated for all participants.ResultsIn the PILATES group there was a reduction in performance (increased test time) for the GI_FC after 4W_DT in relation to POST (p < 0.05), however, GI_FC showing maintenance of performance gain in relation to the PRE (p > 0.05) (PRE: 36.0 ± 5.5 s vs. POST: 27.2 ± 4.0 s vs. 4W_DT: 29.0 ± 4.2 s). The CONTROL group had worse performance than the GI_FC POST (35.3 ± 4.6 s) and 4W_DT (35.4 ± 4.6 s) when compared to the PILATES group (F = 106.967; np2 = 0.842; p < 0.001).ConclusionA period of 4W_DT was not able to reduce the functional gains of elderly women with T2D after 12 weeks of PILATES training. These results have a practical application for training professionals, enabling better control and planning of training interruptions on the PILATES method for elderly women with T2D.     

Exercise dependence,body dismorphia,and anxiety in crossfit practitioners: A cross-sectional study

IntroductionPhysical exercise provides better body image perception and well-being. However, if practiced compulsively, it may lead to compulsion and psychobiological damage. CrossFit is a method aiming at maximum performance, and it is currently attracting many regular practitioners.ObjectiveEvaluate exercise dependence prevalence, muscle dysmorphia, and trait-state anxiety in CrossFit practitioners.MethodsOne hundred fifty regular male CrossFit practitioners were evaluated and subdivided into two groups: with and without risk for exercise dependence. Trait-state anxiety and muscle dysmorphia were also assessed. Unpaired t-test compared groups, Fisher's exact test was used for associations between categorical variables (p < 0.05), while correlations were verified using Pearson's correlation coefficient.Results122 participants were identified with no risk for exercise dependence and 28 with risk for exercise dependence. Participants presented mean age of 30.3 ± 7.05 years and had been practicing physical exercise for 8.02 ± 8.1 years, with training frequency of 5.3 ± 1.09 days per week and 107.9 ± 50.5 min per training day. Prevalence risk of exercise dependence was 18.6%, and muscle dysmorphia was significantly different between groups with (10.7%, n = 3) and without risk (6.6%, n = 8) for exercise dependence. Participants with risk for dependence chose CrossFit mainly due to appearance (32%).ConclusionPrevalence risk of exercise dependence was 18.6% and satisfaction with muscle appearance may influence exercise behavior.     

Feasibility and preliminary efficacy of a hypopressive exercise program on postmenopausal cancer survivors: A pilot study

BackgroundCancer-related fatigue (CRF) is a common symptom during and after cancer treatment that negatively affects the patient's quality of life. Exercise is one of the most effective non-pharmacological treatments for CRF. Multimodal exercise therapy programs that include hypopressive exercises, relaxation and myofascial release may be beneficial for CRF. The aim of this pilot study was to evaluate the feasibility and efficacy of a multimodal program on CRF and lower limb functional strength in postmenopausal women diagnosed with cancer.Methods7 postmenopausal women (age = 55.28 years; BMI = 26.05 kg/m2) who had a cancer diagnosis participated in a supervised and progressive 55-min class once per week for 12-weeks. CRF was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cancer Related Fatigue 12 and lower limb strength was assessed with the sit and stand test.ResultsNo adverse events were reported during the training period and all participants completed the exercise protocol. There was a significant increase (p = 0.01) in lower limb functional strength (pre: 19.60 (SD = 2.19) vs post: 24.60(SD = 2.19)) with an effect size of d = 2.28 and a decrease in CRF (p = 0.245) (pre: 29.36 ± 24.42; post: 17.85 ± 14.23) with a trivial effect size (d < 0.5).ConclusionsThese preliminary findings indicate that a supervised once per week multimodal program that includes hypopressive exercises for postmenopausal cancer survivors increased lower limb functional strength without exacerbating their CRF. These findings support further randomized trials of hypopressive training programs on patients with cancer.     

Effects of core stability training program on trunk muscle endurance in deaf children: A preliminary study

IntroductionSport participation is an important for deaf children as participants experience physical, psychological and social benefits; however, the beneficial effect of core stability training on core muscle endurance is unclear. The present study aimed to examine the effects of an 8-week core stability exercise training program on endurance of trunk muscles in deaf children.MethodsTwenty male deaf students (age, 16.5 ± 0.65 y; body mass, 62.08 ± 5.39 kg; BMI, 22.33 ± 2.24 kg/m²) volunteered to participate in this study and were randomly assigned to experimental (EXP, n = 10) and control (CON, n = 10) groups. The subjects in the EXP group performed 3 times a week for 8 weeks period of core stability training program and tested trunk muscle endurance including prone bridge, supine bridge and flexor endurance tests at pre and post 8 weeks intervention.ResultsThe CON group did not show any significant change after training period (p > 0.05). The EXP group showed significantly changes in core stability muscle endurance tests following the 8-week core stability training program (p < 0.05). In addition, the EXP group indicated statistically significant changes than the CON group in truck muscle endurance (p < 0.05).ConclusionsThe results indicated that core stability training program improved trunk muscle endurance. Therefore, this training approach can be recommended in deaf rehabilitation programs to improve trunk muscle endurance.
