Significant Improvements In Body Composition Research Articles

Longitudinal changes in body composition, physiological characteristics, and motor performance of Paralympic goalball athletes

Research has yet to explore the long-term influences of physical fitness parameters on goalball and how COVID-19 affected athletes’ training program. This study evaluated the longitudinal changes in body composition (BC), postural balance (PB), maximal isometric grip force (MIGF), vertical jump (countermovement (CJ), squat jump (SJ), and peak oxygen consumption (VO2peak) in seven male Paralympic goalball athletes preparing for the Tokyo 2020 Paralympics. Six measurements were performed three times ([first] pre-lock down: January 2020, [second] post-lock down: September 2020, and [third] final follow-up: June 2021) on a variable-by-variable basis. Post hoc tests showed a significant improvement in BC at the third time point compared to the first and second time points. Concomitantly, PB and MIGF were significantly improved at the third time point compared to the first and second time points, respectively. A significant decline was observed in CJ and SJ heights at the second time point compared to the first time point whereas SJ height increased at the third time point compared to the second time point. No change was observed in CJ height at the third time point versus the second time point. There was a dramatic reduction in VO2peak at the second time point compared to the first time point. No change was observed in VO2peak occurred at the third time point versus pre and post lock down. Even with the disruption in the annual training plan due to COVID-19 pandemic, our participants maintained physical fitness levels with home-based exercises.

Exercise training: which impact on COPD patients?

Introduction: Exercise training reactivates the aerobic pathway through physical exercise, thereby improving dyspnea and breaking deconditioning spiral in chronic obstructive pulmonary disease (COPD) patients. Method: 60 COPD patients were selected to benefit from a four-week outpatient exercise training and muscle strengthening program, at a rate of 3 sessions per week, after excluding the following cases: patients who have contraindications to exercise training; severe patients or those receiving long-term oxygen therapy. The program combined exercise training on a bicycle ergometer for 45 min, muscle strengthening of the lower limbs and nutritional monitoring. Nutritional management included a diet based on nutritional status and the prescription of oral food supplements for malnourished COPD patients. Parameters assessed before and after training were bioimpedance analysis (BIA),6MWT, quadriceps isometric voluntary contraction (MVC) and dynamic endurance, and the quality-of-life questionnaire (Q11). Result: Forty COPD patients (36 men and 4 women) aged 67.22 (± 10) years were able to complete the program. Amid them, 36 were non-smokers. Ten patients (GOLD I), 14 patients (GOLD II), 16 patients (GOLD III), no patients (GOLD IV). Dyspnea was stage 2 (± 1) m MRC. After training, quadriceps muscle function ((MVC) and endurance) improved significantly (p < 0.0001). The improvement in distance covered during 6MWT was also significant (p < 0.0001). A significant improvement in quality of life after training was noted on the total score of the Q11 questionnaire. No significant improvement in body composition after training in COPD patients. Conclusion: this study has confirmed the beneficial effects of training mainly on muscle function, effort capacity and quality of life in COPD patients.

Abstract 18383: Body Composition Changes in Peak Oxygen Uptake Responders and Non-Responders During Cardiac Rehabilitation

Introduction: Cardiac rehabilitation (CR) is known to improve peak oxygen uptake (VO 2 peak) and body composition (BC). However, not all CR patients improve VO 2 peak and it remains unclear if non-responders also exhibit limited improvement in BC. This study aimed to examine if non-responders to VO 2 peak also demonstrate limited improvement in BC and whether BC is related to VO 2 peak changes in CR patients. Methods: Retrospective analysis of patients who completed CR between 2015 and 2022 at Mayo Clinic. The study included 143 patients who completed both dual-energy X-ray absorptiometry and cardiopulmonary exercise testing before and after CR. Patients were grouped by VO 2 peak response to CR (36 non-responders=Δ≤0 vs 107 responders=Δ>0 mL/kg/min). Within and between-group differences were assessed by paired and independent t-tests respectively. Regression models were used to evaluate whether baseline BC or ΔBC predict VO 2 peak changes. Results: As an entire cohort there were significant mean improvements in VO 2 peak and BC (Table 1, p<0.05). VO 2 peak increased in 75% of patients (responders: Δ 2.9±2 vs non-responders: Δ -2.1 ±2, mL/kg/min, p<0.05). There were no significant differences in baseline characteristics between groups including BC (Table 2, p>0.05); however, non-responders had significantly shorter duration and exercise sessions compared to responders (Table 2, p<0.001). Non-responders for VO 2 peak exhibited a significant improvement in body fat mass, body lean percentage, body fat percentage, and fat mass index (all p<0.001), with no differences in ΔBC between groups (Table 3). Regression models revealed no significant BC predictors for VO 2 peak. Conclusion: Despite significant improvements in BC, 25% of patients did not improve VO 2 peak with CR. These data suggest VO 2 peak improvement is not related to baseline BC or change in BC. These findings suggest the need for additional strategies to maximize improvements in VO 2 peak for patients undergoing CR.

Feasibility of exercise therapy for children with asthma: a meta-analysis.

Background: Although numerous studies have demonstrated the clear benefits of exercise for people with asthma, controversy remains. This study evaluated the effects of sustained exercise types on lung function and quality of life in patients with asthma. Methods: We searched PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang database since January 2000 to August 2022 .included randomized controlled trials (RCTs) of asthmatic children intervened with exercise. The outcomes were lung function and asthma-related quality of life. Fixed-effects model (I2≤50%) or random-effects model (I2>50%) was applied to calculate the pooled effects. Funnel plots were quantified to present publication bias, and a P value <0.05 was statistically significant. Results: Eventually, 15 trials conformed to the selection criteria. The exercise group significantly improved lung function (FEV1 and FVC) in asthmatic children compared with the control group. Forced Expiratory Volume in 1 Second (MD = 2.12, 95%CI = 0.70, 3.53; p = 0.003; I2 = 15%); Forced Vital Capacity (MD = 2.78, 95%CI = 1.26, 4.31; p = 0.0004; I2 = 56%). The immune system markers IL-6 and TNF-α, were significantly reduced in the exercise group. Interleukin-6 (MD = -0.49, 95%CI = -0.81, -0.17; p = 0.003; I2=0%); tumor necrosis factor-α (MD = -0.54, 95%CI = -0.92, -0.15; p = 0.006; I2 = 0%). That quality of life (PAQLQ) was significantly improved in children with asthma in the exercise group. PAQLQ-Total score (MD = 1.06, 95%CI = 0.46, 1.66; p = 0.006; I2 = 94%); PAQLQ-Emotional (MD = 0.91, 95%CI = 0.76, 1.06; p<0.00001; I2 = 90%); PAQLQ-symptoms (MD = 0.87, 95%CI = 0.71, 1.02; p<0.00001; I2 = 95%); PAQLQ-activities (MD = 1.20, 95%CI = 0.58, 1.82; p = 0.00001; I2 = 93%). Meta-analysis showed significant improvements in body composition in the exercise group. BMI (MD = -2.42, 95%CI = -4.40, 0.44; p = 0.02; I2 = 85%). Conclusions: This meta-analysis demonstrated the effectiveness of exercise in improving pulmonary function index (FEV1, FVC), immune system (IL-6, TNF-α, Feno), exercise ability (6MWT), body composition (BMI), and quality of life (PAQLQ) in asthmatic children. Asthmatic children should regularly participate in physical exercise.

Sindrome progeroide atipica con lipodistrofia parziale familiare, dovuta alla mutazione missenso c.1045 C &gt; T (p.Arg349Trp) in eterozigosi del gene LMNA, e diabete mellito di tipo 2

Familial partial lipodystrophy (FPLD) associated with LMNA gene mutations is a rare form of lipodystrophy disorder characterized by partial absence of subcutaneous adipose tissue and predisposition to develop metabolic complications related to insulin-resistance inclu-ding type 2 diabetes mellitus (T2D). Recently, this peculiar phenotype has been associated to atypical progeroid syndrome (APS). We present a case of 31-year-old woman with progeria features, partial lipodystro¬phy, type 2 diabetes mellitus (T2D), hypertriglyceridemia and hepatic steatosis. The baseline insulin sensitivity and secretion assessment showed strong insulin-resistance with hyperglycemia and elevated insulin secretion. Genetic analysis revealed a missense heterozygous LMNA mutation c.1045 C &gt; T (p. Arg349Trp) that established APS diagnosis with FPLD, so far studied and described in only 10 patients worldwide. The patient was initially treated with metformin, fenofi¬brate, omega-3 and low carb and low fat diet with optimal results on metabolic control related to glycemic and lipid profile; later, liragluti¬de (Glucagon-Like Peptide-1 analog, GLP-1) therapy was added. Du¬ring the 6 month follow-up the anthropometric parameters improved, in particular a significant improvement in body composition with redi¬stribution of fat mass and a reduction of visceral fat and liver volume were observed. The improvements obtained were consolidated and maintained in the following years. However, with disease progression, focal segmental glomerulosclerosis (FSGS) and peripheral neuropathy developed. This case highlights the clinical and metabolic characteristics of this rare form of lipodystrophy and proposes an innovative therapeutic approach to manage the disease.

Supplementation with inulin-type fructans affects gut microbiota and attenuates some of the cardiometabolic benefits of a plant-based diet in individuals with overweight or obesity.

The gut microbiota has emerged as a potential therapeutic target to improve the management of obesity and its comorbidities. We investigated the impact of a high fiber (∼38 g/d) plant-based diet, consumed ad libitum, with or without added inulin-type fructans (ITF), on the gut microbiota composition and cardiometabolic outcomes in subjects with obesity. We also tested if baseline Prevotella/Bacteroides (P/B) ratio predicts weight loss outcomes. This is a secondary exploratory analysis from the PREVENTOMICS study, in which 100 subjects (82 completers) aged 18-65 years with body mass index 27-40 kg/m2 were randomized to 10 weeks of double-blinded treatment with a personalized or a generic plant-based diet. Changes from baseline to end-of-trial in gut microbiota composition (16S rRNA gene amplicon sequencing), body composition, cardiometabolic health and inflammatory markers were evaluated in the whole cohort (n = 82), and also compared in the subgroup of subjects who were supplemented with an additional 20 g/d ITF-prebiotics (n = 21) or their controls (n = 22). In response to the plant-based diet, all subjects lost weight (-3.2 [95% CI -3.9, -2.5] kg) and experienced significant improvements in body composition and cardiometabolic health indices. Addition of ITF to the plant-based diet reduced microbial diversity (Shannon index) and selectively increased Bifidobacterium and Faecalibacterium (q < 0.05). The change in the latter was significantly associated with higher values of insulin and HOMA-IR and lower HDL cholesterol. In addition, the LDL:HDL ratio and the concentrations of IL-10, MCP-1 and TNFα were significantly elevated in the ITF-subgroup. There was no relationship between baseline P/B ratio and changes in body weight (r = -0.07, p = 0.53). A plant-based diet consumed ad libitum modestly decreases body weight and has multiple health benefits in individuals with obesity. Addition of ITF-prebiotics on top this naturally fiber-rich background selectively changes gut microbiota composition and attenuates some of the realized cardiometabolic benefits.

Effect of High-Intensity Interval Training vs. Moderate-Intensity Continuous Training on Fat Loss and Cardiorespiratory Fitness in the Young and Middle-Aged a Systematic Review and Meta-Analysis

This systematic review is conducted to evaluate the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on body composition and cardiorespiratory fitness (CRF) in the young and middle-aged. Seven databases were searched from their inception to 22 October 2022 for studies (randomized controlled trials only) with HIIT and MICT intervention. Meta-analysis was carried out for within-group (pre-intervention vs. post-intervention) and between-group (HIIT vs. MICT) comparisons for change in body mass (BM), body mass index (BMI), waist circumference (WC), percent fat mass (PFM), fat mass (FM), fat-free mass (FFM), and CRF. A total of 1738 studies were retrieved from the database, and 29 studies were included in the meta-analysis. Within-group analyses indicated that both HIIT and MICT can bring significant improvement in body composition and CRF, except for FFM. Between-group analyses found that compared to MICT, HIIT brings significant benefits to WC, PFM, and VO2peak. The effect of HIIT on fat loss and CRF in the young and middle-aged is similar to or better than MICT, which might be influenced by age (18-45 years), complications (obesity), duration (>6 weeks), frequency, and HIIT interval. Despite the clinical significance of the improvement being limited, HIIT appears to be more time-saving and enjoyable than MICT.

Comparison of selected performance-associated parameters after off-season and two-month training preparation in professional Czech ice hockey players

Background: In ice hockey, regular off-ice testing can serve as a controlling mechanism for a training program's effectiveness. Objective: The main aim of this study was to describe changes in selected morphological and physiological parameters, intended to be relevant for a complex ice hockey performance, after two months of pre-season training preparation following one month of an off-season period. Methods: The sample consisted of 22 adult male players aged 18-39 years from a top Czech ice hockey league team. Two laboratory testing procedures performed at the end of the off-season and after two months of the pre-season conditioning consisted of basic anthropometry and body composition measurements, countermovement jump (CMJ), and maximal incremental test focused on the assessment of various parameters, including maximal oxygen consumption (V&#775;O2max), maximal power output during the test (Pmax) or estimation of anaerobic threshold intensity (ANT). Results: After the pre-season, we found a significant decrease in body fat (13.7 vs. 11.4%, p &lt; .001) and an increase in fat-free mass (74.2 vs. 76.6 kg, p &lt; .001), V&#775;O2max (relative 48.8 vs. 52.6 ml.kg-1.min-1 p = .001; absolute 4.20 vs. 4.54 L.min-1, p &lt; .001), Pmax (5.26 vs. 5.44 W.kg-1, p = .011), power output at ANT (4.07 vs. 4.35 W.kg-1, p &lt; .001), and CMJ (44.9 vs. 47.1 cm, p = .002). Conclusions: Based on our results, two months of the pre-season training program led to a significant improvement in body composition and physical performance levels in professional Czech ice hockey players.

The effect of HIIT on body composition, cardiovascular fitness, psychological well-being, and executive function of overweight/obese female young adults.

To evaluate the effect of a short-term HIIT program on the selected health-related parameters for overweight/obese young adult women in a university context. A total of 48 participants were randomly divided into two groups. The exercise group (HIIT) received a HIIT intervention of aerobics for 4 weeks, while the control group (CON) received no training. Body composition including waist circumference (WC), body fat percentage (BF %), Cardiorespiratory fitness (VO2max), the score of Self-Rating Depression Scale (SDS), and Stroop word-color test (SCWT) results were assessed before and after the intervention along with within- and between-group comparisons. All the indices were significantly improved in HIIT group (p < 0.01) after 4 weeks of intervention. No significant changes were found in CON. There were significant differences between HIIT and CON in cardiovascular fitness (p < 0.01), SDS (p < 0.01) and SCWT (p < 0.05) before and after 4 weeks. In addition, weekly measurements of HIIT effects showed significant changes (p < 0.01) from the second week in the variables of body composition, VO2max, SDS and SCWT when compared with the baseline and maintained the tendency till the end of program. The short-term HIIT aerobics of the campus program conducted in a non-lab setting induced significant improvements in body composition, cardiovascular fitness, psychological well-being and executive function in overweight young female adults.

Abstract 10487: In vivo Efficacy of HS135, a Novel Activin and GDF Trap for the Treatment of Pulmonary Hypertension (PH) and Metabolic Syndrome (MetS)

Introduction: PH is a disorder characterized by remodeling of the pulmonary vasculature which causes increased pulmonary vascular resistance and ultimately right ventricular (RV) failure leading to death. MetS is a recognized risk factor for PH, particularly in patients suffering from PH associated with left-sided heart failure (WHO Group 2 PH) for which there are no approved therapies. Activins and growth differentiation factors (GDFs) are implicated in both PH pathology as well as body composition and metabolism by genetic disease association, preclinical, translational, and clinical evidence. HS135 is a rationally designed first-in-class activin-receptor (ActR)-based fusion protein that addresses both vascular remodeling and MetS in PH without affecting hematological parameters; hematological effects limit the dosing of other ActR-based agents. Methods: HS135’s ability to counteract vascular remodeling and heart failure in PH was assessed using a rat monocrotaline (MCT) model: a single dose of 60 mg/kg MCT was administered on Day 0 followed by 4 weeks of twice weekly treatment with either HS135 (1, 4, or 16 mg/kg) or vehicle. PH efficacy was assessed at end of study by echocardiography and histological readouts. HS135’s ability to improve body composition and metabolism was assessed in wild type mice by administering HS135 (1, 3, 10, 20, or 50 mg/kg) or vehicle twice weekly for 3 weeks. The effect of HS135 on hematological parameters was assessed by whole blood cell count in non-human primates (NHPs) 2 weeks following a single administration of HS135 at 3 or 30 mg/kg. Results: HS135 at 3 or 30 mg/kg did not lead to changes in hematological parameters in NHPs. Compared to vehicle, HS135 was effective at counteracting the MCT-induced PH phenotype in rats as evidenced by significant reductions in Fulton index and improved echocardiography parameters. In wild type mice, HS135 led to significant improvements in body composition. Conclusions: Contrary to other ActR-based therapies, HS135 did not lead to increases in hematocrit which would limit its dosing. HS135 was efficacious at treating PH while simultaneously improving body composition in preclinical models. Clinical trials with HS135 are expected to commence within 2023.

Effects and dose-response relationship of exercise training on cardiometabolic risk factors in children with obesity.

To explore the dose-response relationship between physical activity and the improvement of cardiometabolic risks in children with obesity, and provide a reference for the recommendation of physical activity for obese children. A total of 96 children with obesity were recruited to participate in an exercise intervention program. An ActiGraph GT3X+ three-axis accelerometer was used to measure their physical activity. The dose groups (Q1∼Q4) were divided based on the quartiles of physical activity. The analysis of variance was used to compare the changes in body composition and cardiometabolic risk factors before and after the intervention. All intervention groups showed a significant reduction in weight, body mass index, body fat percent, fat mass, fat free mass, and skeletal muscle mass (p<0.01), andthe change in the Q4 and Q3 groups was greater than intheQ2 and Q1 groups. Triglyceride, total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were significantly reduced after intervention in all groups (p<0.01), and the change in SBP, and DBP in the Q4 group was higher than in the Q1 group (p<0.05). Exercise interventions could effectively improve body composition and cardiometabolic risk factors. A higher exercise dose is associated with significant improvements in body composition, and cardiometabolic health.

Effect of circuit training with low-carbohydrate diet on body composition, cardiometabolic indices, and exercise capacity in adults with mild to moderate obesity in Saudi Arabia: A randomized control trial.

Background:Circuit training that combines aerobic and resisted training is reported to reduce body fat, weight, and improve exercise capacity than performing either type of exercise independently. There is no study evaluating the combined effect of circuit training exercise (CTE) and dietary intervention (low-carbohydrate [LC] diet) among young males with obesity.Methods:A randomized control trial was conducted to explore the effects of a combined program of CTE and a LC diet for adults with mild or moderate obesity. Seventy adults with obesity were allocated randomly into 2 groups. The experimental group (group 1) received circuit training with LC diet intervention, whereas the control (group 2) received only circuit training. The study variables such as exercise capacity, body composition, and cardiometabolic indices were measured at the baseline and the end of 60 days of intervention.Results:The participants of group 1 showed significant improvements in body composition (body weight, body mass index, waist circumference, waist hip circumference, and body fat percentage), exercise capacity (maximal oxygen consumption), and cardiometabolic indices (high-density lipoprotein, low-density lipoprotein, triglycerides, and total cholesterol) with a P < .05 for all the variables, when compared with group 2.Conclusions:The combined structured CTE with controlled LC diet intervention in obese adults caused significant reduction in body composition and cardiometabolic indices variables and an increase in exercise capacity.

The Impact of Dietary Counselling on Achieving or Maintaining Normal Nutritional Status in Patients with Early and Locally Advanced Breast Cancer Undergoing Perioperative Chemotherapy.

Background: Obesity is an independent prognostic factor and is associated with poorer response to oncological treatment of breast cancer. Obesity is associated with shorter overall survival and shorter time to recurrence. Material and methods: The study included 104 breast cancer patients qualified for neoadjuvant chemotherapy. The control group consisted of 40 patients who refused to participate in the study. Consultation before chemotherapy included: author’s diet questionnaire, body composition analysis, nutrition education. After chemotherapy, the effects of the first dietary advice were evaluated. Results: More than half of all women had a BMI above normal before treatment. Analysis of the effects of nutrition education showed a significant improvement in body composition. After education, a slight increase in body weight and a significant decrease in fat mass and fat percentage were observed. In women who did not participate in education, a statistically significantly greater increase in body weight after chemotherapy was noted. Nutrition education of the study group did not prevent adverse changes in lipid profile resulting from chemotherapy. Conclusions: Dietary counselling prior to neoadjuvant chemotherapy may limit weight gain and may also influence fat mass reduction. Implementation of dietary recommendations does not guarantee maintenance of normal lipid parameters during chemotherapy.

EFFECTS OF THE ACROBATIC PROGRAM ON THE BODY COMPOSITION AND FLEXIBILITY OF ADOLESCENTS

The aim of the research was to determine the effects of acrobatics programs (ground floor and skipping) on the body composition and flexibility of adolescents. The sample consisted of 50 male adolescents, seventh grade students of the elementary school "Bubanjski Heroji" in Niš, aged 14 years ± 6 months. The experimental group (n = 25) conducted 2 x 45 min per week experimental acrobatics program (ground floor and skipping) The control group (n = 25) continued with the program of regular physical education classes (handball and volleyball) 2 x 45 min per week. The results of the study showed positive changes in body composition: BMI, %MAT, %MIT and flexibility: PLNL, RANL, ISKP caused by the acrobatics program. Based on these results, it can be concluded that the experimental program of acrobatics lasting 16 weeks is an effective method that leads to a statistically significant improvement in body composition and flexibility of adolescents.

A structured physical activity program in an adolescent population with overweight or obesity: a prospective interventional study.

Obesity is a significant health problem, with increasing involvement of young population worldwide. The aim of this study was to evaluate the effects of 2 different types of physical exercise (resistance vs. combined aerobic-resistance) on cardiovascular and anthropometric profile of a sample of sedentary adolescents with overweight and obesity. After undergoing clinical, cardiovascular and anthropometric-metabolic evaluation (T0), subjects with overweight and obesity were randomized to a 6-month resistance or combined aerobic-resistance training program. Clinical, cardiovascular and anthropometric-metabolic evaluations were repeated after 6months of training (T1) and after 3months of detraining (T2). Thirty adolescents with overweight/obesity were enrolled and 20 subjects completed training program. A significant improvement in body composition was detected after 6months, with a reduction of body mass index (32.1 [30.5 to 34.4] vs. 31.1 [29.6 to 33.4] kg/m2, p= 0.02) and adipose tissue (45.5 [41.1 to 49.7] vs. 41.6 [37.0 to 49.2] kg, p< 0.01). A reduction in diastolic blood pressure (75.5± 8.9 vs. 68.2± 6.4mm Hg, p= 0.02) and pulse wave velocity (5.7 [5.1 to 5.9] vs. 5.2 [4.7 to 5.7] m/s, p= 0.04) was also observed. Persistence of the effect on the most important parameters was observed also after detraining period. In conclusion, regular physical exercise induces positive metabolic and cardiovascular effects, persisting even after brief discontinuation. Novelty: Physical exercise induces positive effect on cardiovascular risk profile. Positive effects persist also after brief discontinuation. Physical exercise reduces early signs of autonomic disfunction.

The Effect of Eight Weeks of Aqua Therapy on Back Pain, Body Composition and Motor Function of Inactive Elderly Women

Background and Aims: Aging is along with muscle weakness and musculoskeletal pain that requires attention and planning to control these changes. The purpose of this study was to investigate the effect of eight weeks of aqua therapy on back pain, body composition, and motor function in inactive elderly women. Methods: The present study was quasi-experimental with a pre-test and post-test design of a suitable type. Thirty inactive elderly women were voluntarily and randomly assigned to two experimental and control groups. The experimental group performed combined water exercises for eight weeks, three sessions a week with a maximum intensity of 45 to 65% of the maximum heart rate. Body composition variables were analyzed using body composition analysis device, back pain analyzed by Key Star Back 9-item questionnaires, and movement control variables such as walking speed evaluated using 10 m walking test and the ability to maintain balance analyzed with stand-up and time test, tested before and after the training protocol. And the data were analyzed using the SPSS program and independent and dependent t-test. Results: Based on the findings of the present study, significant improvement in body composition, including weight, fat percentage, muscle tissue, and waist to hip ratio, was observed in elderly women (P=0.001), and the results of the present study showed factors affecting motor control had a significant improvement, such as balance (P=0.001), speed (P=0.001) and physical back pain (P=0.001) and mental back pain (P=0.001) after eight weeks practicing in the water. Conclusion: This study showed that as the elderly live a passive and active life, their physical health improves. To increase the range of motion of the lumbar region, stabilize the trunk, and reduce back pain, trainers and officials can use this non-invasive and low-cost method in the training program and rehabilitation of the elderly individual.

Reversing the effects of androgen-deprivation therapy in men with metastatic castration-resistant prostate cancer.

To investigate whether bipolar androgen therapy (BAT), involving rapid cyclic administration of high-dose testosterone, as a novel treatment for metastatic castration-resistant prostate cancer (mCRPC) promotes improvements in body composition and associated improvements in lipid profiles and quality of life. Men from two completed trials with computed tomography imaging at baseline and after three cycles of BAT were included. Cross-sectional areas of psoas muscle, visceral and subcutaneous fat were measured at the L3 vertebral level. Functional Assessment of Chronic Illness Therapy - Fatigue questionnaire and 36-item short-form health survey were used to assess quality of life. The 60 included patients lost a mean (sd) of 7.8(8.2)% of subcutaneous fat, 9.8(18.2)% of visceral fat, and gained 12.2(6.7)% muscle mass. Changes in subcutaneous and visceral fat were positively correlated with each other (Spearman's correlation coefficient 0.58, 95% confidence interval 0.35-0.71) independent of the effects of age, body mass index, and duration of androgen-deprivation therapy. Energy, physical function, and measures of limitations due to physical health were all significantly improved at 3months. The improvements in body composition were not correlated with decreases in lipid levels or observed improvements in quality of life. In the present study, BAT was associated with significant improvements in body composition, lipid parameters, and quality of life. This has promising implications for the long-term health of men with mCRPC.

Effect of different diet methods on body composition and insulin, leptin, and ghrelin levels in overweight women

Introduction. This study aims to compare the effects of similar calorie-restricted intermittent overnight fasting diet (OFD) and frequent-meal diet (FMD) on body composition and insulin, leptin, and ghrelin levels in overweight women. Materials and Methods: While the FMD was administered as six mealtimes, the OFD was administered as five mealtimes and at least 12 hours overnight fasting for four weeks. Some parameters regarding the metabolic rate and fat metabo-lism (glucose, insulin, HOMA-IR, leptin, ghrelin levels), body composition, resting metabolic rate, and physical activity level were measured before and after the diet. Results: There was no sig-nificant difference in the resting metabolic rate (kcal) and fat-carbohydrate oxidation (g/min), while diet programs showed a similar significant improvement in body composition in both groups (p &lt; 0.05). The glucose and insulin levels in OFD and the insulin level and the insulin re-sistance index in FMD significantly decreased (p &lt; 0.05). There were significant differences in the leptin (-37%) and ghrelin (5.8%) levels in FMD, but only a significant decrease in the leptin level (-49%) was observed in OFD. Conclusions: After a 4-week same calorie-restricted FMD with six meals and OFD with a 12 hour-overnight fasting, similar improvements in the body composition and the insulin, leptin, and ghrelin levels have been achieved.

Effects of two personalized dietary strategies during a 2-year intervention in subjects with nonalcoholic fatty liver disease: A randomized trial.

Nonalcoholic fatty liver disease (NAFLD) management is focused on lifestyle modifications, but long-term maintenance is a challenge for many individuals. This study aimed to evaluate the long-term effects of two personalized energy-restricted dietary strategies on weight loss, metabolic and hepatic outcomes in overweight/obese subjects with NAFLD. Ninety-eight subjects from the Fatty Liver in Obesity (FLiO) study (NCT03183193) were randomly assigned to the American Heart Association (AHA) or the FLiO dietary group in a 2-year controlled trial. Anthropometry, body composition (DXA), biochemical parameters and hepatic status (ultrasonography, Magnetic Resonance Imaging, and elastography) were assessed at baseline, 6, 12 and 24months. Both the AHA and FLiO diets significantly reduced body weight at 6 (-9.7% vs -10.1%), 12 (-6.7% vs -9.6%), and 24months (-4.8% vs -7.6%) with significant improvements in body composition, biochemical and liver determinations throughout the intervention. At the end of the follow-up, the FLiO groupshowed a greater decrease in ALT, liver stiffness and Fatty Liver Index, among others, comparedto AHA group, although these differences were attenuated when the analyses were adjusted by weight loss percentage. The FLiO group also showed a greater increase in adiponectin compared to AHA group. The AHA and FLiO diets were able to improve body weight and body composition, as well as metabolic and hepatic status of participants with overweight/obesity and NAFLD within a 2-year follow-up. These findings show that both strategies are suitable alternatives for NAFLD management. However, the FLiO strategy may provide more persistent benefits in metabolic and hepatic parameters.

Undergraduate Curriculum Designed to Facilitate a Cancer Exercise Rehabilitation Program.

In 2030, more than 22.1 million cancer survivors are expected to reside in the USA. A workforce knowledgeable in the unique issues of oncologic exercise design and delivery will help to fulfill the need for services that improve survivor health, prognosis, and quality of life (QOL). The purpose of this project was to describe the application of a cancer exercise rehabilitation training program on student performance benchmarks and patient outcomes. Thirty-seven kinesiology students were taught how to design an exercise program for cancer patients through face-to-face instruction (10h) and online material. Students created and delivered exercise prescriptions to cancer patients (n = 111) over 12weeks. Surveys evaluating student performance, patient fitness, and patient psychosocial outcomes were used to assess students' skill proficiency, ability to apply newly acquired knowledge, and academic/professional growth. A 2-way ANOVA evaluating student performance scores revealed a significant main effect of time (F(1, 165) = 22.92, p < 0.001), indicating that student performance was improved. Post hoc tests showed the "skill proficiency, knowledge and exercise leadership" dimension was significantly improved (p < 0.0001). Cancer patients had significant improvements in body composition, muscular function, flexibility, and balance (p < 0.05). Students succeeded in tasks directly related to content learned in prerequisite kinesiology courses, while 3weeks was required for students to become proficient in clinic-related duties. Ninety percent of the students reported that the internship was an excellent learning experience. The curriculum was successful in teaching students how to design and implement exercise programs that improve cancer patient fitness and QOL.
