Effect of body morphology on standing balance in adolescent idiopathic scoliosis

OBJECTIVES: The objective of this study was to determine the effect of body somatotype on standing balance in girls with adolescent idiopathic scoliosis (AIS) who are under observation but not wearing a body brace. DESIGN: In all, 74 girls participated in this study to form the able-bodied (n = 36) and the AIS (n = 38) groups, having an average age of 13 yrs. Quiet standing balance was tested using a force platform. Afterward, subjects in each group were divided according to their dominant body somatotype, namely endomorphs (fatness), mesomorphs (muscular), or endomorphic ectomorphs (lean). RESULTS: The center of pressure measured in the anteroposterior position was closer to the heels for the AIS ectomorphic group by approximately 14 mm (P = 0.00497). Only the AIS mesomorphic group displayed a statistically significant 12-mm shift to the right in their center of pressure (P = 0.01211) compared with the able-bodied girls of the same morphotype. In the endomorphic group, the sway area was statistically higher for the scoliotic subjects (P = 0.00839). The distances traveled by the AIS subjects were all statistically longer for all three body morphologic somatotypes. CONCLUSION: Different postural responses seem to be dependent on body somatotypes. The endomorphic AIS girls had a larger sway area than their able-bodied counterparts while maintaining a similar center of pressure position. The AIS ectomorphic girls had a tendency to lean further back than a comparable able-bodied group. This could be emphasizing a hypokyphotic trunk attitude and increasing the risk of spinal deformity progression. The AIS mesomorphic subjects characterized by a large muscular and bony structure had a tendency to position their center of mass more to their right, indicating less postural adaptability and a stiffer trunk.

Somatotype and body composition analysis of Korean youth soccer players according to playing position for sports physiotherapy research

[Purpose] The purpose of this study was to investigate the somatotype and physical characteristic differences among elite youth soccer players. [Subjects and Methods] In the present study, we evaluated twenty-two Korean youth soccer players in different playing positions. The playing positions were divided into forward (FW), midfielder (MF), defender (DF), and goalkeeper (GK). The participants’ lean body mass (LBM), fat free mass (FFM), fat mass (FM), and basal metabolic rate (BMR) were measured and their somatotype determined according to the Heath-Carter method. [Results] The youth soccer players had twelve ectomorphic, eight mesomorphic, and two central predominant types. The DFs were taller than, but otherwise similar in physical characteristics to the FWs and MFs. The GKs were taller and heavier than the other players; however, their somatotype components were not significantly different. LBM, FFM, and BMR were significantly higher in GKs than in FWs and MFs. Although LBM, FFM, and BMR values between GKs and DFs showed large differences, they were not statistically significant. [Conclusion] The present study may contribute to our understanding of the differences in somatotype and body composition of Korean youth soccer players involved in sports physiotherapy research.Key words: Korean youth soccer players, Somatotype, Sports physiotherapy     

Ayurvedic genomics, constitutional psychology, and endocrinology: the missing connection

A recent methodological approach for human classification, diagnosis, and therapeutics through the combination of current Western constitutional psychology somatotypes and traditional Indian medicine (prakriti) body types and mind (manas) is herein presented. The striking similarities between psychologic somatotypes and Indian medicine body types permits proposal of a finite genopsycho-somatotyping of humans. Genopsycho-somatotyping of humans consists of a set of common physiologic, physical, and psychologic attributes related to a common basic birth constitution that remains somewhat permanent during human lifetime, since it is proposed that this birth constitution is programmed in the person's DNA (genes). This mainly provides a tool for classifying the human population based on broad and finite phenotype clusters across different ethnicity, languages, geographical location, or self-reported ancestry. In spite of any social or environmental traumatic event, I propose for males that every basic constitution has an associated identification organ, a measured property or marker, a soma, and some psyche general tendencies suggesting specific behavior or recurrent conduct. Three (3) basic extreme genopsycho-somatotypes or birth constitutions are enunciated: mesomorphic or andrus (Pitta), endomorphic or thymus (Khapa), and ectomorphic or thyrus (Vata). The method further predicts that male andrus constitution across races shares similarities in androgen (An) nuclear receptor behavior, whereas thymus constitutions are mainly regulated by T-cells (Tc) nuclear receptor behavior. Moreover, it suggests that thyrus constitutions share similarities in thyroxine (Th) nuclear receptor behavior. These proposed nuclear receptors are expected to regulate the expression of specific genes, thereby controlling the embryonic development, adult homeostasis, and metabolism of the human organism in a very profound way. The method finally predicts small differences in measured property (An, Tc, and Th nuclear receptors behavior) within a birth constitution across different races to be expected by modulation effects in melanocyte-stimulating hormone receptor behavior.     

Analysis of combat sports players’ injuries according to playing style for sports physiotherapy research

[Purpose] This study describes the characteristics of injuries in strike and non-strike combat sports, and the results are intended for use in the area of sports physiotherapy research. [Subjects and Methods] The study was conducted on 159 athletes involved in a variety of combat sports. The participants included elite college players of the following sports: judo (47), ssireum (19), wrestling (13), kendo (30), boxing (16), and taekwondo (34). Of the participants, 133 were male and 26 were female. In the case of ssireum and boxing, all of the athletes were male. [Results] In the case of the combat sports, the types of injury and injured regions differed according to playing style. Dislocation and injuries to the neck, shoulders, and elbows were more frequent in the non-strike sports, while injuries to the wrists and hands were more frequent in the strike sports. There was a high incidence of sprains, strains, bruises, and injuries to the lower limbs in both groups. [Conclusion] We suggest that the characteristics of injuries in combat sports differ according to playing style, and our study will therefore provide physical therapists and researchers with information that can be used to prevent injury.Key words: Combat sports, Injury, Sports physiotherapy research     

Analysis of isokinetic muscle strength for sports physiotherapy research in Korean ssireum athletes

[Purpose] The purpose of the present study was to elucidate the muscle conditions such as the isokinetic muscle of Korean ssireum athletes. [Subjects and Methods] This study enrolled 25 elite ssireum athletes. We measured body composition and peak torque at an angular speed at 60°/s using an isokinetic muscle strength dynamometer. [Results] The lean body mass of the left upper limb was significantly higher than that of the right upper limb. However, the lean body mass of the left lower limb was significantly lower than that of the right lower limb. The peak torque for left elbow flexion was significantly higher than that for right elbow flexion. Conversely, the peak torque for left elbow extension was significantly lower than that for right elbow extension. Furthermore, the peak torque for the left knee was significantly lower than that for the right knee for both flexion and extension. [Conclusion] The data from this study elucidate in part the muscle conditions of Korean ssireum athletes, which can be used to establish a reference for the scientific study of sports physiotherapy.Key words: Isokinetic muscle strength, Ssireum athletes, Sports physiotherapy     

A Comparison of the Foot and Ankle Condition between Elite Athletes and Non-athletes

[Purpose] The purpose of this study was to compare the foot and ankle condition between elite athletes and non-athletes. [Subjects] The elite athletes group included 85 subjects (28 males and 57 females) and the non-athletes group included 85 subjects (38 males and 47 females). [Methods] All subjects were evaluated for pain (visual analogue scale, VAS) and foot and ankle condition (The Foot and Ankle Disability Index, FADI, and The Foot and Ankle Outcome Score, FAOS). [Results] The elite athlete group showed significant differences from the non-athletes group in VAS, FADI (FADI, FADI-Sports), and FAOS (FAOS-symptoms, FAOS-pain, FAOS-ADL, FAOS-sports, FAOS-QoL). In addition, a meaningful difference in VAS, FADI-Sports, and FAOS-symptoms was observed between gymnasts and wrestlers. [Conclusion] The results of this study suggest the necessity prevention of injury to the foot and ankle of elite athletes, and for the development of exercise for the rehabilitation of foot and ankle injuries, because there is a difference in foot and ankle condition between elite athletes and non-athletes.Key words: Elite athletes, FAOS, Ankle     

Determination of a splenic volumetric index by ultrasonic scanning.

In a prospective study carried out to determine spleen size by a rapid and simple ultrasonic method, 45 normal subjects, 20 men and 25 women, average age 54 +/- 17 years (range 17-78) were studied. The three principal dimensions of the spleen, breadth, thickness, and height, were obtained with a compound scan technique; each dimension was measured at its largest point. The values obtained were multiplied by each other and the product arbitrarily divided by 27, which is the cube of the three values. This gave a splenic volumetric index (SVI), which, in 95 per cent of normal subjects, was between 8 and 34. There were no statistically significant differences related to age, sex, or morphotype when endomorphs, ectomorphs, and mesomorphs were examined. This SVI determination, based on standardized measurements, allows the distinction of normal from abnormal spleens in 10 minutes.     

Characteristics of Postural Muscle Activation Patterns Induced by Unexpected Surface Perturbations in Elite Ski Jumpers

[Purpose] This study investigated the characteristics of postural control following postural disturbance in elite athletes. [Subjects] Ten elite ski jumpers and ten control subjects participated in this study. [Methods] Subjects were required to maintain balance without stepping following unexpected horizontal surface perturbation in a forward or backward direction. [Results] A lower and reproducible peak magnitude of the center of mass velocity was shown in the athlete group compared to the control group. Cross-correlation analyses showed longer time lags at the moment of peak correlation coefficient between trunk flexor and extensor muscle activities, and shorter time lags and higher correlations between ankle flexor and extensor muscle activities were shown in the athlete group than in the control group. [Conclusion] The elite ski jumpers showed superior balance performance following surface perturbations, more reciprocal patterns in agonist-antagonist pairs of proximal postural muscles, and more co-contraction patterns in distal postural muscles during automatic postural responses than control individuals. This strategy may be useful in sports requiring effective balance recovery in environments with a dynamically changing surface, as well as in rehabilitation.Key words: Postural reactions, Ski jumpers, Muscle activation pattern     

Postural Stability and Subsequent Sports Injuries during Indoor Season of Athletes

[Purpose] The aim of this study was to analyze stabilometry in athletes during an indoor season in order to determine whether injured athletes show different stabilometric values before injury than non-injured athletes in two different training periods (volume and pre-competition periods). [Subjects] The subjects were 51 athletes from Unicaja athletic club who trained regularly. [Methods] At the end of the preseason and volume periods, athletes were subjected to bipodal and monopodal stabilometry. In addition, all injuries happening in the periods after performing stabilometry (volume and pre-competition periods) were tracked. [Results] Variance analysis of bipodal stabilometric measurements taken at the end of the preseason period showed that athletes with higher values for the center-of-pressure spread variables suffered injuries during the volume period. The right-leg monopodal stabilometric measurements taken at the end of the volume period showed that athletes with higher values in the center-of-pressure position variables suffered injuries during the pre-competition period. [Conclusion] Athletes showing the worst values for center-of-pressure spread variables are more prone to sports injuries in the subsequent training period. In monopodal measurements, athletes with poorer mediolateral stability were more prone to injuries in the subsequent training period.Key words: Sports injury, Athletes, Postural stability     

Fitness Testing Athletes

Fitness testing of athletes can be subdivided into tests of body build, strength, aerobic power, and tests specific to the athletic event. World class athletes seem to fall into specific body types for the individual events. The top athlete usually has very little of the endomorphic characteristics and should be lean.Strength testing should be used more frequently as weight and isometric training techniques are used by many athletes and coaches without specific goals. The aerobic power of many national class athletes may be only 10-30 percent above that of the general population, and high values were found only in cyclists and distance runners. It is emphasized that the scores of fitness tests are specific for each test and do not necessarily correlate at all with athletic performance which is also specific. Despite this limitation, fitness tests do have a place in athletics and should be utilized more fully and with more understanding by coaches and athletes.     

Effect of Weight-bearing Therapeutic Exercise on the Q-angle and Muscle Activity Onset Times of Elite Athletes with Patellofemoral Pain Syndrome: A Randomized Controlled Trial

[Purpose] The purpose of this study was to determine the effect of a weight-bearing therapeutic exercise program for elite athletes diagnosed as having patellofemoral pain syndrome (PFPS). [Subjects] The subjects were 34 elite athletes from the Seoul T Center. They were randomly allocated to three groups: an elastic band exercise group (EBG), a sling exercise group (SEG), or a control group (CG). [Methods] Therapeutic exercises were performed 3 times a week for 8 weeks. The visual analogue scale (VAS) hamstring length, and static and dynamic Q angles were used to test the exercise effect of the exercises, as well as the onset time of electromyographic activity of vastus medialis oblique (VMO) and vastus lateralis (VL). [Results] Decrease of the dynamic Q-angle in EBG was significant and significantly greater than that in CG. The decrease in VAS in SEG was significant and significantly greater than that in CG. There were significant differences in the VL and VMO activity onset times in SEG between pre- and post-test, and their differences between pre- and post-test were also significantly different. [Conclusion] Weight-bearing therapeutic exercise is hoped that clinicians will use this information for better implementation of effective exercise methods for elite athletes with PFPS.Key words: Electromyographic onset time, Patellofemoral pain syndrome, Q-angle     

Longitudinal study on locations of injury among junior high school,high school,and university badminton athletes at Japanese national-level competitions

[Purpose] The aim of study was to examine incidence of injury according to location of injury to develop an injury prevention program for elite badminton players of junior high school, high school, and university. [Participants and Methods] We conducted a prospective longitudinal study, between April 2012 and March 2013, on 133 national-level badminton players attending junior high school, high school, and university. Injury rates in athletes per 1,000 exposures were calculated based on gender and school age for the five most common injury locations, in addition, severity, type and circumstance were investigated. [Results] Injury rates in athletes per 1,000 exposures were the highest in the racket-side (RS) shoulder/clavicle among the female university students (4.35), RS thigh of high school females (2.21), and lumbar spine/lower back of males of all school ages and junior high school females (1.83–1.25). Significantly higher injury rates were noted for the overuse of the lumbar spine/lower back and RS shoulder/clavicle, trauma of the RS thigh and ankle, and injury, when compared with slight injury of the RS ankle. [Conclusion] Injury prevention programs should be developed for RS shoulder/clavicle overuse in university females, RS thigh trauma in high school females, and lumbar spine/lower back in males of all school ages and junior high school females.     

The effect of sports on level of community integration as reported by persons with spinal cord injury.

OBJECTIVE: The purpose of this study was to determine whether participation in sports by persons with spinal cord injuries (SCIs) affected level of community integration as defined by the World Health Organization and as measured by the Craig Handicap Assessment and Reporting Technique (CHART). METHOD: Forty-eight participants were recruited from a camp for persons with physical disabilities as well as from SCI support groups. Participants were divided into groups of athletes (n = 30) and nonathletes (n = 18) on the basis of their self-reported level of sports participation. RESULTS: Athletes scored significantly higher on four of five subsections of the CHART (physical independence, mobility, occupation, social integration), indicating greater levels of community integration than nonathletes. CONCLUSION: These findings extend the literature outlining the physical and psychological benefits of sports. Occupational therapists have a unique opportunity to use the occupation of sports to integrate the roots of the profession with the cultural demands of society.     

The relationship between children’s somatotypes,motor examination results,and motor skills: assessing 6- to 10-year-olds

[Purpose] Childhood motor disorders and obesity are major health problems and concerns in children today. We performed a physical examination to test the motor system and motor ability of elementary school children based on their body types. [Participants and Methods] The obesity levels of 161 elementary school students aged six to ten were calculated based on the gender, age, and standard weight for each height category to classify them into somatotype groups, and analyze the relationships among the results of four motor examination items, Physical Fitness Test, and body composition analysis for two groups. [Results] More obese children were unable to reach the floor while performing a standing forward bend compared to non-obese children. In addition, a significant difference was found in the assessment of motor performance while performing side-to-side jumping, and obese children showed better values. Many endomorphic children were also unable to touch the floor with their hands when performing the standing forward bend. Among the items from a physical fitness test, the side-to-side hops revealed significant differences. There were no somatotype-related differences in the results of the body composition analysis. [Conclusion] In children aged six to ten years, somatotype differences were not associated with motor skill or body composition.     

ACTN3 genotype influences muscle performance through the regulation of calcineurin signaling

α-Actinin-3 deficiency occurs in approximately 16% of the global population due to homozygosity for a common nonsense polymorphism in the ACTN3 gene. Loss of α-actinin-3 is associated with reduced power and enhanced endurance capacity in elite athletes and nonathletes due to “slowing” of the metabolic and physiological properties of fast fibers. Here, we have shown that α-actinin-3 deficiency results in increased calcineurin activity in mouse and human skeletal muscle and enhanced adaptive response to endurance training. α-Actinin-2, which is differentially expressed in α-actinin-3–deficient muscle, has higher binding affinity for calsarcin-2, a key inhibitor of calcineurin activation. We have further demonstrated that α-actinin-2 competes with calcineurin for binding to calsarcin-2, resulting in enhanced calcineurin signaling and reprogramming of the metabolic phenotype of fast muscle fibers. Our data provide a mechanistic explanation for the effects of the ACTN3 genotype on skeletal muscle performance in elite athletes and on adaptation to changing physical demands in the general population. In addition, we have demonstrated that the sarcomeric α-actinins play a role in the regulation of calcineurin signaling.     

The influence of athletic status and gender on experimental pain responses

To examine the role of athletic status and gender on experimental pain responses, 24 athletes (12 male, 12 female) and 24 nonathletes (12 male, 12 female) participated in 3 experimental pain tasks. After a series of psychologic inventories and demographic questionnaires, pressure pain thresholds (4 sites: pectoralis, trapezius, biceps, quadriceps), ischemic pain threshold and tolerance (lower arm), and cold pressor pain threshold and tolerance (lower arm) were assessed. No significant overall effects of athletic status or gender were identified for measures of pressure pain threshold. No group differences emerged for ischemic pain threshold. Athletes demonstrated significantly higher tolerance for ischemic pain, and cold pressor pain threshold and tolerance were higher among athletes than nonathletes. Overall analyses indicated higher pain thresholds and tolerance for cold pain among men than among women. A final interview found that many participants who approached the upper limits of these pain tasks reported using a competitive coping strategy.     

Health maintenance: paraplegic athletes and nonathletes

The relationship between participation in competitive wheelchair sports and health maintenance in individuals having paraplegia was examined. Twenty-one wheelchair athletes and 21 nonathletes completed two self-report questionnaires. The t-test for Independent Groups, the Mann-Whitney U-Test, and the Test for Significance of Difference Between Two Proportions were used to test for group differences. A p value of 0.05 significance level was used. The subjects were similar in age, sex, race, education, age at onset of injury, duration of injury, and preinjury level of sports involvement. A large percentage of both groups had been hospitalized since rehabilitation discharge; however, the mean number of hospitalizations per year since discharge was almost three times greater for nonathletes. Fewer athletes had been hospitalized for pressure sores. Within the athlete group the more serious medical complications occurred before beginning wheelchair sports. Frequency counts of specific complications occurring during the past year showed that nonathletes had more serious conditions such as kidney infections and skin breakdowns due to pressure as opposed to those due to external trauma. The findings indicate that paraplegic athletes are more successful than nonathletes in avoiding the major medical complications for which they are at risk. It follows, then, that this athletically active subgroup of the paraplegic population is costing the individual, medical insurance companies, and the state less money for ongoing medical care and extensive repeat hospitalizations.     

Short-term Effects of a Proprioceptive Training Session with Unstable Platforms on the Monopodal Stabilometry of Athletes

To analyze the short-term effects of a proprioceptive session on the monopodal stabilometry of athletes. [Subjects] Thirty-seven athletes were divided into a control group (n=17) and an experimental group (n=20). [Methods] Both groups performed a conventional warm-up, after which a 25-minute proprioceptive session on ustable platforms was carried out only by the experimental group. Before the training session, all athletes carried out a single-leg stabilometry test which was repeated just after training, 30 minutes, 1 hour, 6 hours and 24 hours later. [Results] Analysis of covariance (α=0.05) revealed that the experimental group had lower values than the control group in length and velocity of center of pressure (CoP) of left-monopodal stance and in velocity of CoP of right-monopodal stance in post-training measurements. Also, the experimental group had values closer to zero for the CoP position in the mediolateral and anteroposterior directions of left-monopodal stance (Xmeanl and Ymeanl) and the anteroposterior direction in on right-monopodal stance (Ymeanr) in post-training measurements. Within-group analysis of Xmeanl and Ymeanl, length and velocity of CoP in right-monopodal stance showed continuous fluctuations of values between sequential measurements in the control group. [Conclusion] Proprioceptive training on unstable platfoms after a warm-up stabilizes the position of CoP in the anteroposterior and mediolateral directions and decreases CoP movements in short-term monopodal stability of athletes.Key words: Proprioception, Athletes, Stabilometry
