Physical fitness profile of elite athletes with intellectual disability

The aim of this study was to investigate the physical fitness profile of high-performance athletes with intellectual disability (ID) in comparison with able-bodied individuals. METHODS: Participants were 231 male and 82 female athletes. All evaluations were done using the EUROFIT physical fitness test. RESULTS: In comparison with population data, both male and female athletes with ID score better for flexibility and upper body muscle endurance, but have similar or lower values for running speed, speed of limb movement, and strength measures. Compared with age-matched physical education students, male athletes with ID score better for running speed and flexibility, and worse for strength. Female athletes with ID score not different from able-bodied individuals for flexibility, running speed, and upper body muscle endurance, but worse for strength measures. Athletes with ID also have poorer cardio respiratory endurance capacity compared with sportive peers without ID. Furthermore, male athletes have a more differentiated profile depending upon their sports discipline, compared with female athletes. CONCLUSION: It can be concluded that high-performance athletes with ID reach physical fitness levels that are equal to or lower than those of able-bodied sportive counterparts. Further research should investigate the importance of reduced muscle strength to be the limiting factor.     

Neuromuscular,kinetic and kinematic differences in drop jumping between male adolescents with and without intellectual disability

BackgroundIndividuals with intellectual disability (ID) have lower performance in vertical jumps compared to individuals without ID. Training programmes including drop jump (DJ) exercises to gap this deficit are required. However, there is a lack of knowledge on biomechanical variables may influence DJ performance in young people with ID.Research questionAre there differences in the neuromuscular, kinetic and kinematic parameters in DJ between male adolescents with and without ID (WID and NID, respectively).MethodsThirteen male adolescents WID (Wisk III intelligence quotient: 55.6 ± 11.2) and thirteen age-matched boys NID executed DJ from 30 cm on a force-plate. The vastus lateralis (VL) and biceps femoris (BF) electromyogram (EMG) as well as the knee kinematics and kinetics were obtained.ResultsWID had significantly (p < .05) lower DJ height, knee power, peak angular velocity and stiffness compared to NID. VL activity was higher and BF/VL co-activation was lower in WID than NID.SignificanceThe deficit in DJ performance shown in WID was accompanied with lower power and stiffness, as well as lack of coordination in the lower limb muscles. Improving these variables, with specific and targeted training interventions, may diminish the performance gap with their age-matched counterparts.     

Validation of the PASE in older adults with knee pain and physical disability.

PURPOSE: To examine the validity of the Physical Activity Scale for the Elderly (PASE) among individuals with disability. METHODS: A sample of 471 participants (mean age = 71.36) in an epidemiological study of chronic knee pain completed the PASE and self-report measures of knee pain, perceived physical function, satisfaction with physical function, and importance of physical function. A 6-min walk test and an isokinetic assessment of knee strength were also administered. RESULTS: PASE scores were significantly correlated in expected directions with performance on the 6-min walk, knee strength, frequency of knee pain during transfer, and perceived difficulty with physical functioning. Gender and age were identified as significant moderators of PASE scores and the scale's construct validity was supported by testing a conceptually driven hypothesis regarding patterns of physical activity. CONCLUSIONS: These results support the PASE's validity for the assessment of physical activity among older adults with pain and disability.     

Food and fluid intake and hydration status does not affect ultrasound measurements of subcutaneous adipose tissue in active adults

ObjectivesTo investigate the impact of acute food and fluid intake or hydration status on the standardised brightness-mode ultrasound measurement of subcutaneous adipose tissue thickness.DesignThirty active adults (female n = 10) participated in a randomised cross over study.MethodsParticipants completed three body composition assessment sessions via standardised brightness-mode ultrasound and Dual-energy X-ray absorptiometry. Participants were assessed under standardised presentation during ‘food only’ and ‘food plus water’ sessions at baseline and reassessed after their allotted intake. ‘Hypohydration plus water’ was undertaken in a hypohydrated state at baseline and reassessed after water intake.ResultsThe sum of eight subcutaneous adipose tissue thickness was lower when measured after ‘food only’ or ‘food plus water’ compared to baseline (?0.1 to ?0.9 mm; p < 0.01). However, these changes were less than the 95% confidence interval of the technical error of measurement of the investigator. Body mass, dual-energy x-ray absorptiometry total and trunk mass, lean mass and trunk lean mass estimates increased (p < 0.01) following ‘food only’ or ‘food plus water’, and decreased with hypohydration (p < 0.01). Total and regional fat mass estimates were not impacted.ConclusionsThe sum of eight subcutaneous adipose tissue thickness measured via standardised brightness-mode ultrasound was unaffected by acute food and fluid consumption or hydration status changes. Comparatively, these interventions altered dual-energy x-ray absorptiometry body composition estimates, especially that of lean mass components. Standardised brightness-mode ultrasound can therefore be used to monitor changes in fat patterning when standardised client presentation is not practically achievable.     

Prolonged survival of a female patient with total pelvic exenteration

BACKGROUND: To present a female patient who lived 5 years after total pelvic exenteration (TPE). CASE REPORT: The female patient underwent TPE due to retrovesicovaginal fistula as a consequence of locoregional irradiation after the operation for the malignoma of the vaginal part of the uterus. In the formation of Bricker conduit, the ureter antireflux was achieved by the application of the "tobacco sack muff" made of the intestines around the ureter. By the use of this technique, the occurrence of pyelonephritis, as the leading cause of death in such patients, was prevented. CONCLUSION: TPE is a hope for significantly prolonged survival of patients with advanced pelvic malignomas, or with a postirradiatiation fistula.

Long-term results of total body irradiation in adults with acute lymphoblastic leukemia

Purpose

The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome.

Patients and methods

A total of 110 adult patients (34?±?12 years) with ALL underwent TBI (6?fractions of ?2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported.

Results

Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72?%, respectively. In all, 29?% (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22?%, and 60 and 52.7?%, respectively. The most frequent late reaction wascGVHD of the skin (n?=?33, 30?%). In addition, 15.5?% (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110?=?28?%); 12 of 110 patients (11?%) presented with symptoms from osteoporosis, 5 of 110 patients (4.5?%) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11?% reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented.

Conclusion

Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic breadth.     

Correlation of Short Form-36 and disability status with outcomes of arthroscopic acetabular labral debridement

BACKGROUND: Arthroscopic debridement is the standard of care for the treatment of acetabular labral tears. The Short Form-36 has not been used to measure hip arthroscopy outcomes, and the impact of disability status on hip arthroscopy outcomes has not been reported. HYPOTHESIS: Short Form-36 subscale scores will demonstrate good correlation with the modified Harris hip score, but patients undergoing disability evaluation will have significantly worse outcome scores. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The records of active-duty soldiers who underwent hip arthroscopy at the authors' institution were retrospectively reviewed. Forty consecutive patients who underwent hip arthroscopy for the primary indication of labral tear formed the basis of the study group. Patients completed the modified Harris hip score, the Short Form-36 general health survey, and a subjective overall satisfaction questionnaire. RESULTS: Thirty-three patients, with a mean age of 34.6 years, were available for follow-up at a mean of 25.7 months postoperatively. Fourteen (43%) patients were undergoing medical evaluation boards (military equivalent of workers' compensation or disability claim). Pearson correlation coefficients for comparing the Short Form-36 Bodily Pain, Physical Function, and Physical Component subscale scores to the modified Harris hip score were 0.73, 0.71, and 0.85, respectively (P < .001). The mean modified Harris hip score was significantly lower in patients on disability status than in those who were not (92.4 vs 61.1; P < .0001). The Short Form-36 subscale scores were significantly lower in disability patients (P < .02). Patient-reported satisfaction rates (70% overall) were 50% for those undergoing disability evaluations and 84% for those who were not (P < .04). There was no significant difference in outcomes based on patient age, surgically proven chondromalacia, or gender for military evaluation board status. CONCLUSION: The Short Form-36 demonstrated good correlation with the modified Harris hip score for measuring outcomes after arthroscopic partial limbectomy. Arthroscopic debridement yielded a high percentage of good results when patients undergoing disability evaluations were excluded. Disability status may be a negative predictor of success after hip arthroscopy.     

Objective assessment of activity in older adults at risk for mobility disability

PURPOSE: The purpose of this study was to evaluate the validity of three objective measures of physical activity (Accusplit Eagle 120 mechanical pedometer (AE120), NL-2000 electronic pedometer, and IDEEA pattern-recognition device) that varied in their levels of sophistication, among older adults at risk for mobility disability. In addition, we examined the potential influences of gait speed and body mass index (BMI) on step count accuracy. METHODS: Step counts recorded on the three devices were compared against manual step counts made by two investigators as each participant walked 131 m around an indoor track at their preferred walking speed (N=29; 75.8+/-4.2 yr). Gait speed was determined by dividing total distance walked by time to completion. BMI was calculated from height and body mass measurements. RESULTS: All three devices significantly underestimated steps taken (AE120=22.8+/-53.9 steps; NL-2000=4.0+/-5.8 steps; IDEEA=5.6+/-7.8 steps), but there was no significant difference between devices (P=0.084). Steps counted by the AE120, NL-2000, and IDEEA were significantly correlated with manual step counts (r=0.508, 0.980, and 0.965, respectively; P相似文献   

Physical activity status and postprandial lipaemia in older adults

Physical activity-induced lowering of postprandial lipaemia is short-lived. However, little is known regarding the role of physical activity status on postprandial lipaemia. The purpose of the present study was to compare postprandial triacylglycerol concentrations in active and inactive older adults. A total of 26 older adults (aged 69.8±0.9 years, mean±SEM; 10 male and 16 female) were analysed in a cross-sectional design. Based on accelerometer data, participants were divided into either the active group (≥150?min/week of moderate-intensity physical activity, N=15) or the inactive group (<150?min/week of moderate-intensity physical activity, N=11). After a 48-h period of physical activity avoidance and a 10-h overnight fast, participants consumed a test meal of moderate fat content (35%). Capillary blood samples were collected in the fasted state and at 2, 4, and 6?h postprandially. After adjusting for fasting triacylglycerol concentrations, body mass, body mass index and waist circumference, postprandial capillary triacylglycerol concentrations were significantly lower in the active than inactive group ( P=0.046). These findings demonstrate that regular physical activity lowers postprandial lipaemia independent of the acute effects of physical activity in older adults.     

Television time and continuous metabolic risk in physically active adults

PURPOSE: Among Australian adults who met the public health guideline for the minimum health-enhancing levels of physical activity, we examined the dose-response associations of television-viewing time with continuous metabolic risk variables. METHODS: Data were analyzed on 2031 men and 2033 women aged > or = 25 yr from the 1999-2000 Australian Diabetes, Obesity and Lifestyle study without clinically diagnosed diabetes or heart disease, who reported at least 2.5 h.wk of moderate- to vigorous-intensity physical activity. Waist circumference, resting blood pressure, and fasting and 2-h plasma glucose, triglycerides, and high-density-lipoprotein cholesterol (HDL-C) were measured. The cross-sectional associations of these metabolic variables with quartiles and hours per day of self-reported television-viewing time were examined separately for men and for women. Analyses were adjusted for age, education, income, smoking, diet quality, alcohol intake, parental history of diabetes, and total physical activity time, as well as menopausal status and current use of postmenopausal hormones for women. RESULTS: Significant, detrimental dose-response associations of television-viewing time were observed with waist circumference, systolic blood pressure, and 2-h plasma glucose in men and women, and with fasting plasma glucose, triglycerides, and HDL-C in women. The associations were stronger in women than in men, with significant gender interactions observed for triglycerides and HDL-C. Though waist circumference attenuated the associations, they remained statistically significant for 2-h plasma glucose in men and women, and for triglycerides and HDL-C in women. CONCLUSIONS: In a population of healthy Australian adults who met the public health guideline for physical activity, television-viewing time was positively associated with a number of metabolic risk variables. These findings support the case for a concurrent sedentary behavior and health guideline for adults, which is in addition to the public health guideline on physical activity.     

全踝关节置换术的现状与进展

1历史回顾Morton-Murdock在1970年首次于临床使用人工踝关节[1]。当时人工踝关节是引伸于将髋关节假体翻转180°而来,胫骨部件借助长柄插入髓腔,类似全髋的股骨头部件,远端由聚乙烯的距骨体构成,行踝关节置换的同时做距下关节融合。经10年25例随访,12例失败,仅7例满意。在随后的八、九十年代,共有约20多种的踝关节假体用于临床。人工踝关节分为限制型、非限制型和半限制型三大类。限制型是指假体对某方向活动的限制能力,如对前后向或对旋转向的限制,常用的有铰链式设计,能提供极强的内稳定,不易脱位,也不形成对内外踝的撞击。但高限制型在…     

Colonic total and segmental transit times in healthy Italian adults

Purpose

This study was done to determine colonic transit times in healthy Italian adults.

Materials and methods

Institutional review board approval and informed patient consent were obtained. Colonic segmental radiopaque markers were counted and transit times calculated in 36 healthy subjects studied using a technique involving daily radiopaque marker ingestion and single radiological visit, with oral administration of 8–10 ml of a thick barium paste as a colonic trace for the marker count. Two independent radiologists counted the marker twice. Observer agreement was assessed using comparison analysis.

Results

There was very good observer agreement for the segmental marker counts. The upper limit for colonic transit times was: 45.6 h in the colon as a whole, 31.2 h in the right colon, 19.2 h in the left colon and 16.8 h in the rectosigmoid. Colonic transit times were not gender-related.

Conclusions

In healthy subjects, a barium trace affords optimal visibility of the different colonic segments, enabling accurate location of all markers and thus providing an anatomy-related, repeatable and reproducible fluoroscopic segmental marker count. We suggest that the reference values for normal colonic transit times could be adopted for Italian people irrespective of gender.     

Association between sleep quality and physical fitness in female young adults

AIM: Sleep quality and physical fitness are critical for young adults' growth and health. However, no study has examined the association between sleep quality and physical fitness in young adults. METHODS: A total of 291 female college students (mean age: 19.3+/-0.6 years; mean height: 160.3+/-5.2 cm; mean weight: 52.2+/-9.8 kg), in the northern part of Taiwan, volunteered as subjects. For sleep quality evaluation, a valid Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used. For physical fitness testing, a battery of field-based health-related fitness tests was conducted by well-trained instructors. Data was analyzed using independent t-tests and the Pearson product-moment correlation coefficient. RESULTS: Subjects with poor sleep quality (P) (PSQI score >5) were more likely to have lower levels of muscular endurance, flexibility, and cardiovascular fitness. Significant correlations were also found between the global PSQI score and physical fitness performances in female young adults. CONCLUSION: This study confirmed the high prevalence of P among young adults. Education materials should try to prevent young adults from developing poor sleep patterns and inactive lifestyles. Moreover, subjects with P should take better care of health problems from cardiovascular disease and musculoskeletal injury.     

Growth and menarcheal status of elite female gymnasts.

The growth and maturity status of 201 elite female gymnasts was considered. The subjects were participants at the 24 World Championship Artistic Gymnastics in 1987. In addition to age at menarche, weight, stature, biacromial, and bicristal breadths, the sitting height/stature ratio, and the Health-Carter anthropometric somatotype of gymnasts 13-20 yr of age were compared with reference data for a nationally representative sample of Flemish girls. Median age at menarche (probit analysis) in gymnasts is 15.6 +/- 2.1 yr compared with 13.2 +/- 1.2 yr in Flemish girls. Anthropometric dimensions increase with age until about 16 yr and then tend to plateau. In contrast to body size, there is little variation in somatotype with age. Compared with adolescent girls, elite gymnasts are considerably shorter and lighter with narrower shoulders and hips, but the differences are more apparent after 17 yr. Elite gymnasts do not differ from nonathletes in relative leg length, but they have proportionally broader shoulders relative to hips. Differences in somatotype occur primarily in endomorphy (especially lower in gymnasts) and to a lesser extent in mesomorphy (higher in gymnasts).     

Nutritional status and body composition of adolescent female gymnasts

Nutritional status and body composition of 26 young female gymnasts (average age 12 years) were studied. The body fat percentage (15% of total body weight) is low, still consistent with an excellent health. The caloric intake is lower (1552 kcal/day) than that recommended for their age group, however it is still within the standard by body weight (43 kcal/kg). They show and insufficient assumption of carbohydrates (47.7%), mineral salts and vitamins, so that a more detailed alimentary information is required in order to avoid undesired consequences on sport performance and growth rate.
