AbstractCurrently it is hypothesized that increased body mass index may contribute to overuse injuries. Thus, if hip or shoulder range of motion is affected by body mass index, pitchers may be placing additional stress on joints as they seek to pitch at maximal velocity. The purpose of this study was to examine if range of motion at the hips and shoulders were related to body mass index classification. A sample of 147 female softball pitchers (17.0±4.2 years; 167.6±11.8 cm; 70.6±17.5 kg; body mass index=24.8±4.7 kg/m2) participated. Bilateral hip and shoulder range of motion were assessed. Multivariate analysis of variance results indicated body mass index [Wilks’ Λ=0.742, F=1.722, p=0.014, η2=0.095] significantly affected range of motion of the shoulder and hip. Post hoc results indicated the underweight group had significantly more range of motion than the obese group in hip internal range of motion on both the throwing side (mean difference=12.39, p=0.005) and glove side (mean difference=11.98, p=0.004). Although body composition is not overly emphasized among softball pitchers, the current study reveals excess weight may inhibit proper mechanics. Coaches, athletic trainers, strength and conditioning personnel, and athletes should acknowledge the role that body composition can play in affecting pitch outcomes.

Introduction: This cross-sectional study evaluated the healthy, active lifestyle capacity (daily physical activity, strength, flexibility, body composition) of children after Fontan, which was hypothesized to be lower than healthy peers. Methods: Participants (n=64, 25 female) were 9 ± 2 years of age. Fontan completion occurred at 3 ± 1 years of age. Canadian Health Measures Survey protocols assessed aerobic endurance (walking up/down steps at set pace), strength (handgrip dynamometry), flexibility (sit and reach), body composition (body mass index) and daily moderate-to-vigorous physical activity (7-day accelerometry). Participant versus published norm differences were evaluated with t-tests. Linear regression evaluated associations with age/gender/demographic factors. Results: Children after Fontan had strength scores similar (mean difference 1 kg) to their peers, were less likely to be obese (mean difference of body mass index = 1.1 ± 2.5, p=.001) and performed 50 minutes of moderate-to-vigorous activity per day. Estimated maximal aerobic endurance (mean difference = 21 ± 3 ml/kg/min or 61% of expected) and flexibility (mean difference = 9 ± 8 cm or 64% of expected) were lower than peers(p<.001). Participants performed fewer minutes of daily activity (mean difference from normal 12 ± 17 minutes/day, p<.001), but almost all (60/63) demonstrated the capacity for at least 20 minutes per day. Daily activity was higher with Fontan completion at a younger age (4 ± 2 mins/year) and for those taking antithrombotic medication (7 ± 18 and 22 ± 17 fewer minutes/day for those taking/not taking antithrombotics, respectively). Conclusions: Children after Fontan demonstrate the capacity to successfully perform the daily physical activity associated with optimal health. They have similar levels of strength and good body composition. We recommend that children after Fontan be counselled to expect that they can successfully participate in physically active peer play.

Aims: To report the evolution of a breast cancer survivor after an eight-week aerobic training program.Case Description: A 47-year-old breast cancer patient, submitted to mastectomy about five years before, followed by radiation therapy and chemotherapy, was submitted to aerobic training on cycle ergometer and treadmill for eight weeks, two sessions per week, with gradual increase in training volume. Cardiorespiratory capacity, static strength, upper body mobility, level of physical activity, and body composition were assessed before and after the training protocol. The patient demonstrated improvement in left ventricular ejection fraction, decrement of heart rate at rest and during exercise, and increase in shoulder range of motion and in physical activity level. A reduction of visceral fat was also observed. There was no improvement in muscle strength or in maximum capacity of oxygen use.Conclusions: This case report describes improvements in cardiorespiratory capacity, in shoulder range of motion, in the level of physical activity, and in body composition, after an eight-week aerobic training (two weekly sessions), in a breast cancer patient who had undergone mastectomy, radiation therapy, and chemotherapy.

Abstract Effective training to improve serve speed is important for competitive tennis players. The purposes of this study were to investigate the effects of anthropometric factors and whole body kinematics of elite players on ball speed and to propose possible training strategies for improving the quality of tennis serves. Body and racket kinematics of tennis serves of 12 male elite Hong Kong players were investigated. The tennis serve was divided into four phases: I) Back-Swing Phase, II) Lead-Leg-Drive Phase, III) Forward-Swing Phase, and IV) Follow-Through Phase. It was shown that racket-side knee range of motion during phases II and III (r=0.705; p<0.05), racket-side knee peak extension velocity during phase II (r=0.751; p<0.01), racket-side hip peak extension velocity during phase II (r=0.657; p<0.05), racket-side shoulder range of motion in the coronal plane during phase III (r=0.616; p<0.05), racket-side elbow peak extension velocity during phase III (r=0.708; p<0.01) and body mass index (r=0.577; p<0.05) were significantly correlated with ball speed. Body mass index and the identified kinematic parameters that were significantly correlated with ball speed could be used as training guidelines for coaches and players to improve serve speed. Players should pay particular attention in training to increasing the extension velocity and range of motion of the identified joints.

This is a preliminary study to investigate the feasibility of electronic moxibustion in breast cancer patients with upper limb lymphedema. As current treatment options for lymphedema are unsatisfactory and time consuming, there have been attempts to manage symptoms using integrative treatments. Electronic moxibustion was developed to compensate for the shortcomings of conventional moxibustion and is widely used in clinical practice. However, there have been no studies on using electronic moxibustion in breast cancer-related lymphedema. To investigate the feasibility of electronic moxibustion in treating breast cancer-related lymphedema, this study included subjects who completed primary cancer treatment at least 6 months ago and had more than 10 mm difference in arm circumference of upper limbs. All subjects were assigned to the treatment group. Subjects were treated with 16 sessions (30 minutes/session) of electronic moxibustion for 8 weeks followed by 4 weeks of follow-up. For outcome measures, upper limb circumferences, shoulder range of motion, bioimpedance analysis, and quality of life questionnaire were assessed. All 10 subjects completed the study. The effective index showed 38.21% reduction after treatment ( P = .0098) and 29.35% ( P = .0039) after 4 weeks of follow-up compared to the baseline. The reduction of lymphedema was most prominent at 10 cm above the elbow crease, where the mean reduction of circumference difference was 7.5 mm ( P = .0430) and continued to improve after treatment (mean reduction of 8.3 mm, P = .0156). There was significant improvement in shoulder range of motion only in flexion and internal rotation at week 9. There were 7 adverse events, and most were irrelevant to the treatment. Only 1 participant had a mild burn on the acupuncture point. Here, we demonstrate for the first time that electronic moxibustion treatment is a feasible treatment for breast cancer-related lymphedema. Electronic moxibustion may reduce differences in upper limb circumference and improve shoulder range of motion. A future comparative clinical trial is needed to confirm the clinical efficacy of this treatment.

BACKGROUND: Persisting shoulder stiffness adversely affects quality of life by causing pain and motion restrictions especially in patients with diabetes. OBJECTIVE: The aim of this study was to evaluate the outcomes of arthroscopic capsular release in patients with idiopathic shoulder stiffness. METHOD: A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. Random-effects meta-analyses were performed to estimate the changes at latest follow-up in scores of the Constant, American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angelis (UCLA) scales, Visual Analogue Scale (VAS), and shoulder range of motion. RESULTS: Nineteen studies were included. The follow-up duration was 42 months [95% confidence interval (CI): 32, 51]. Improvements in scores of the Constant, ASES, UCLA scales, and VAS were 48.3 [95% CI: 38.0, 58.6], 44.6 [95% CI: 24.6, 64.6], 19.3 [95% CI: 16.6, 22.0], and -6.1 [95% CI: -6.9, -5.4] respectively (P< 0.05 all). Improvements in the shoulder range of motion were: abduction 82.0 [95% CI: 65.0, 98.9]; forward flexion 75.9 [95% CI: 59.7, 92.1]; external rotation 43.2 [95% CI: 37.5, 49.0]; and internal rotation 25.4 [95% CI: 15.2, 35.5] degrees; P< 0.05 all). CONCLUSION: Arthroscopic capsular release effectively improves shoulder function in patients with idiopathic shoulder stiffness.

ABSTRACT Objective: Our study aimed to describe body phenotypes (BP) estimated by multivariate analysis and their association with body mass. Design: Body phenotypes were defined based on demographic variables, anthropometric data (body mass, height, skinfolds and circumferences), body composition (phase angle measured by bioelectrical impedance analysis), biochemical parameters (triglycerides, glucose, total cholesterol ratio/Low Density Lipoproteins (LDL), haemoglobin and sexual maturation (pubic hair and breasts or gonads). Analysis of variance (ANOVA) was performed to verify the differences between skin colour and the stages of pubertal development, body phenotypes, body composition, anthropometric, and biochemical variables. Setting: Cities of São Paulo-SP, Piracicaba-SP and Florianópolis-SC from Brazil and the United States. Participants: 9269 adolescents aged between 10 to 15 years old. Results: The composition of BP was similar in all surveys, which are: BP1 was composed by skinfolds, body mass and circumferences variables; BP2 by pubic hair, breast in girls or gonad in boys, height and age; BP3 by cholesterol, triglycerides and glucose; and BP4 by phase angle, haemoglobin and glucose (negative loading). There was a strong correlation (r = 0.9, p <0.001) between BP1 and body mass index. Conclusion: We highlighted independence observed between biochemical parameters, anthropometry, body composition and sexual maturation. BP may support the calculation of scores for diagnosis of obesity based on anthropometric variables and overcome ambiguity in the isolated use of body mass index.

Abstract Objective: To investigate the association between maternal pre-pregnancy body mass index (BMI) and offspring body composition in adulthood. Design: Retrospective cohort. Undergraduates of nutrition or nutritionists were recruited at the baseline of the Nutritionists’ Health Study between 2014 and 2017. Maternal pre-pregnancy BMI and current life aspects were self-reported through online questionnaires. Three body compartments were DXA-determined. The following variables were obtained: body-fat (%), fat mass index (FMI) (kg/m2), android-to-gynoid fat ratio, visceral adipose tissue (VAT) (cm3), appendicular skeletal muscle mass index (ASMI) (kg/m2), total bone and femur mineral content (g) and density (g/cm2). Linear regression adjusted according to directed acyclic graphs recommendation was performed. Setting: São Paulo, Brazil. Participants: Healthy non-pregnant women (aged 20-45 years) (n=150). Results: Median age and BMI were 22 years (IQR=20; 29) and 22.3 kg/m2 (IQR=20.4; 25.3). Pre-pregnancy BMI≥25 kg/m2 was reported by 14.7% of mothers. In fully adjusted models, maternal pre-pregnancy BMI was associated with their daughters’ body-fat % (β=0.31; 95%CI=0.0004; 0.63), FMI (β=0.17; 95%CI=0.03; 0.30, android-to-gynoid ratio (β=0.01; 95%CI=0.004; 0.02) and VAT (β=0.09; 95%CI=0.02; 0.16), but not with total bone density (β=0.001; 95%CI=-0.003; 0.006) and content (β=7.13; 95%CI=-4.19; 18.46). Direct association with ASMI was also detected, but lost statistical significance when participants whose mothers were underweight were excluded. Conclusions: Maternal pre-pregnancy body mass index was directly associated with offspring general and visceral adiposity but seem not to be associated with bone mass. Results reinforce importance of avoiding excess of maternal adiposity, as an attempt to break the vicious cycle of obesity transmission.

The aim of the present study was to analyse body composition, anxiety, cardiovascular, and physical activity factors related with academic performance of school students as well as to analyse differences, by age, in these factors. We analysed in 266 primary school students’ (8.81 ± 1.62 years, range: 5–13 years) heart rate, anthropometric variables to calculate body mass index, physical activity performance, anxiety levels and academic results by the average of marks. Students were divided in two different groups, firstly by their lower or higher academic performance, and secondly by age. Results showed a negative correlation between academic performance and age, weight, body mass index and trait anxiety variables. Additionally, significant differences were found by age, presenting older students higher scores in body mass index and lower physical activity, trait anxiety, heart rate and academic performance values than younger students. Overweight and obesity may have a great impact in academic performance in children and we pointed out the necessity to establish programs related with healthy habits which include improvements in physical activity and nutrition behaviours with the objective to enhance children’s health general status, psychological profile, cognitive and motor development, and academic performance.
