A short-term yoga-based intervention improves balance control, body composition, and some aspects of mental health in the elderly men

Background: Body balance control represents a key function for the physical activities of elderly people aged sixty-five and over. Due to the biological and psychosocial changes in this age group, yoga-based intervention appears to be beneficial to maintaining their ability to balance along with related mental aspects of health. Objective: The aim of the presented study was to examine the effects of the 4-week yoga-based intervention on balance, body composition and the mental health aspects of elderly men. Methods: 67-80-year-old elderly men (N = 234, mean age 72.5 ± 7.7 years) were assessed with The Tinetti Balance Assessment Tool, bioimpedance body composition analyser InBody 230 and the Health Survey SF-36, applied for the pre- and post-testing. The experimental group (n = 122) underwent the 4-week intervention based on yoga exercises, while the control group (n = 112) had a usual daily program at their senior homes or centers. Results: The yoga intervention led to significant improvement of both the static balance and gait scores compared to the control group, with medium effect size, ηp2 = .070 and .080. The intervention also had an effect on the decrease of body fat percentage (by 1.7%) and an increase in muscle mass (by 1.3 kg), with a large effect size, ηp2 = .214 and .301. Results of the Health Survey showed that overall mental health did not change significantly although positive improvement in two items connected with emotional problems. Conclusions: A short-term yoga-based intervention may have a significant positive influence on physical abilities such as balance control and body composition rather than on mental health aspects in elderly men aged sixty-five and over.

Effects of Self-Weighing During Weight Loss Treatment: A 6-Month Randomized Controlled Trial

ObjectiveTo examine the effectiveness of self-weighing for weight loss in men for 6 months.MethodsIn the present study, 54 men, mean age of 40.1 ± 11.1 years, with overweight or obesity, were recruited and randomly assigned into two groups: control group (CG), without weight self-monitoring and intervention group (IG), with weight self-monitoring. Both groups received the same nutritional and educational advice and the establishment of a weight target to reach in the weight loss program. Subjects of IG also had individualized motivating content to improve self-management for 24 weeks. Anthropometric indices were measured at baseline and weekly for 24 weeks.Results When the group assigned after randomization was introduced in the analysis, its influence was significant in weight loss (F1.52 = 19.465, ± 2 = 0.272, p < 0.001) and in the decrease in body fat percentage (F1.52 = 8,306, ± 2 = 0.132, p < 0.01).ConclusionStudy results indicate that self-weighing can help patients to lose additional weight. Our findings have implications in the emerging area of the behavioral approach of patients undergoing weight-loss treatment, as well as clinical care processes.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier NCT04032249.

A Long-Term Pilot Study on Sex and Spinal Cord Injury Shows Sexual Dimorphism in Functional Recovery and Cardio-Metabolic Responses

More than a quarter of a million individuals in the US live with spinal cord injury (SCI). SCI disrupts neural circuitry to vital organs in the body. Despite severe incidences of long-term peripheral complications from SCI, the cardio-metabolic consequences and divergences in sex-related responses are not well described. We examined the effects of SCI on functional recovery, cardiac structure and function, body composition, and glucose metabolism on adult female and male Sprague Dawley (SD) rats. SCI was induced at T10 via contusion. Measured outcomes include behavioral assessment, body weight, dual-energy X-ray absorptiometry (DEXA) for body composition, echocardiography for cardiac structure and function, intraperitoneal glucose tolerance test (IPGTT) for glucose metabolism, insulin tolerance test (ITT), and histology of cardiac structure at the endpoint. There was a decrease in body fat percentage in both sexes, with SCI females disproportionately affected in percent body fat change. Left ventricular internal diameter during systole (LVIDs) was decreased in SCI females more than in SCI males. No significant differences in glucose metabolism were observed up to 20 weeks post-injury (PI). These data show significant cardio-metabolic differences as a consequence of SCI and, furthermore, that sex is an underlying factor in these differences.

Electrically induced cycling and nutritional counseling for counteracting obesity after spinal cord injury: A pilot study

Objective: The purpose of this pilot study was to determine the preliminary efficacy of interval functional electrical stimulation (FES) cycling combined with nutritional counseling in obese adults with SCI. Setting: Community-based individuals with chronic SCI. Participants: Ten participants with chronic SCI. Interventions: Participants were divided into 2 groups (1) FES cycling and nutritional counseling (FES & Nutri) and (2) nutritional counseling only (Nutri Only). The FES & Nutri group performed high intensity interval FES cycling for 30 min 3 times per week for 8 weeks and received nutritional counseling for 30 min once per week for 8 weeks. The Nutri Only group received the nutritional counseling only. Outcome Measures: Body composition (fat mass, lean mass, body fat percentage), blood glucose levels. Results: Participants in the FES & Nutri group had a statistically significant greater decrease in body fat percentage (M = −1.14) compared to those in the Nutri Only group (M = +0.28) and gained more lean mass in their legs (M = +0.66 kg) compared to the Nutri Only group (M = –1.05 kg). Discussion/Conclusion: The statistically significant decrease in body fat percentage for the FES & Nutri group provides evidence that further study is merited. Future studies should include larger numbers of participants and the possible introduction of a preliminary strengthening program before initiating interval FES cycling. In addition, an increase in exercise volume and a greater role for nutritional counseling should be considered in order to optimize the treatment for obesity.

Structured Physical Activity did not Affect the Body Fat Percentage among Gymnastics Studio Members

The excess of body fat in the body can be associated with the risk of diabetes, cardiovascular disease, and other metabolic diseases. Activit ies which can reduce the body fat percentage is a structured physical activity . This study aims to identify the effect of the structured physical activity on the decrease in body fat percentage on members of the gymnastics studio. This study use d one group of pretest-posttest design. The intervention was an aerobic exercise , conducted for a minimum duration of 150 minutes per week, and followed up for three months. The samples were selected by using purposive sampling and we re collected by measuring the respondent's weight with Bioelectrical Impedance Analysis at the beginning and the end of this study. The data were analyzed by using paired sample t - test. The result showed that the average of the body fat percentage on the pre-test was 33.156 %, and on the post-test wa s 32.920 %. Based on the data, t here was a decrease in a body fat percentage on pre-test and post-test in 13 out of 25 respondents . The p-value was 0.357, and it can be conclude d that the structured physical activity d id not have a significant effect on the decrease in body fat percentage.

Koroner Arter Baypas Cerrahisi Geçirmiş Hastalarda Bisiklet ve Kol Ergometresi Egzersiz Eğitiminin Fiziksel Fonksiyonlar ve Lipid Profili Üzerine Etkisi: Randomize Bir Çalışma

Objective: The aim of this study was to compare the effects on physical functions (PF) and lipid profile (LP) of bicycle and arm ergometer exercises among the patients, who underwent coronary artery bypass graft (CABG) surgery. Material and Methods: The study involved 50 patients, who underwent CABG surgery. The patients were randomly divided into 2 groups. After the exclusion of 11 cases, evaluation was performed of 23 patients in the bicycle ergometer group (BEG) and 16 patients in the arm ergometer group (AEG). All the subjects participated in a cardiac rehabilitation program consisting of exercise training with bicycle or arm ergometer exercise for a total of 30 sessions as 5 sessions per week during 6 weeks. Before and after the exercise training, the 6-minute walking test distance (6MWTD), body composition evaluation, and blood lipid levels were recorded. Results: Before and after the exercise training, statistically significant positive changes were observed in the BEG including increased 6MWD, and LP parameters containing decreased percentage of body fat, LDL, trigliserid level, and total cholesterol. Statistically significant changes were found in the AEG including increased 6MWTD and LP parameters containing HDL, decreased body fat percentage, BMI, LDL, triglycerides, and total cholesterol. Comparing the values between the groups, it was found that there was a statistically significant increase in the 6MWD in the BEG when compared to the AEG. Conclusions: In conclusion, bicycle and arm ergometer exercises had a positive effect on PF and LP after CABG surgery. For improving the functional capacity, the bicycle ergometer training was seen to be more advantageous.

Obesity is Irreversible Without a Controlled Dietary Regimen in a Murine Model

Category:Diabetes, Hindfoot, Midfoot/Forefoot, obesityIntroduction/Purpose:In recent decades, the prevalence of obesity in the United States has increased dramatically. This can be attributed in-part to the high-fat “Western Diet”. Consequentially, the economic burden of obesity to the healthcare system has rapidly increased, accounting for more than 10 percent of all medical spending in America. Furthermore, with regards to orthopedics, obesity has been shown to be a strong risk factor for musculoskeletal pain, injury, and post-operative complications. The purpose of this study was to determine the effects of high intensity cardiovascular training and controlled dietary intake on body weight, body fat percentage (BFP), and bone mineral density (BMD) in obese and non-obese mice. These results will provide a better understanding of how to optimally facilitate weight loss in obese patients.Methods:Following IAUCUC approval, 8 diet-induced obesity (DIO) C57BL/6 mice were obtained along with 6 non-obese C57BL/6 control mice. DIO mice were fed a high-fat diet (60% fat by kcal) ad libitum starting at the age of 6 weeks. Control mice were fed a standard low-fat diet (10% fat by kcal) ad libitum from birth. Starting at the age of 14 weeks, all mice underwent a controlled high intensity cardiovascular training protocol using a treadmill four times per week at 30 minute intervals. This was carried out for seven weeks including a one-week acclimation period. Speed, distance, and time spent running were all constant between groups. Mouse body weights were recorded several times per week throughout the study. Additionally, BFP and BMD were obtained bi-weekly using dual energy X-ray absorptiometry (DEXA) to assess morphophysiological changes longitudinally.Results:Preliminary investigations with a controlled exercise regimen reveal that obese mice, when fed a high-fat diet, continue to gain weight rapidly despite high intensity cardiovascular training whereas control mice maintain their weight. Following the seven-week training period, control mice gained an average of 1.25 g (p=0.41), while DIO mice gained an average of 8.55 g (p<0.001). DIO mice also showed an 8.74% increase in body fat percentage (p=0.002) while control mice showed a 0.51% decrease in body fat percentage (p=0.75). Lastly, BMD was significantly lower in DIO mice compared to controls following the exercise protocol (p<0.05).Conclusion:The results of this study support the hypothesis that a controlled exercise regimen alone is ineffective for facilitating weight loss. In fact, obese mice administered a high-fat diet actually gain weight despite undergoing a rigorous exercise program. Additionally, simple differences in dietary intake have significant effects on body weight, body fat percentage, and bone mineral density. This suggests that while exercise may play a small role in maintaining a normal weight, obesity is irreversible with exercise alone. Obese orthopedic patients should be counseled on dietary modifications before engaging in an exercise program.

Abstract 183: Phosphodiesterase 9 Inhibition Improves Cardiometabolic Profile in Female Mice Independent of Estrogen Status

Approximately 6.5 million Americans are living with heart failure (HF) currently and the number of persons is projected to increase 46% by 2030. One particularly notable syndrome associated with increasingly severe obesity is called - Heart failure with a preserved ejection fraction (HFpEF); which represents half of all HF patients world-wide. Epidemiologic insights have provided incremental evidence that female sex is a stronger risk factor for HFpEF, particularly post-menopausal women. Loss of estrogen after menopause reduces estrogen receptor induced-NO-cGMP-PKG activation and consequently less benefit from Phosphodiesterase 5(PDE5) inhibition which principally hydrolyze NO-derived cGMP that appears compromised in HFpEF patients. PDE9 targets cGMP generated by Natriuretic peptide (NP) signaling and is significantly increased in hearts from HFpEF patients. This supports a role of PDE9 in the heart and its value as a therapeutic target for abnormalities relevant to HFpEF. We created a murine model of postmenopausal obesity and mild cardiac stress induced HFpEF. Genetic ablation or pharmacological inhibition of PDE9 conferred higher contractile performance with increased %EF, %FS and improved diastolic relaxation and filling. Echo-MRI analysis showed an improvement in whole body metabolism with significant decrease in percent body fat associated with enhanced O 2 consumption and increased energy expenditure. The mechanisms underlying the protective effects are increased mitochondrial function and enhanced expression of transcriptional regulators pgc1α and pparα, driving mitochondrial fatty acid oxidation and increased energy dissipation. Our work identifies for the first-time reversal of changes in substrate metabolism, and mitochondrial dynamics as a direct consequence of PDE9 inhibition in heart and fat. Proteomic analysis also revealed a dynamic cross-talk of PDE9 protein with biological networks of mitochondrial membrane proteins and proteins regulating cellular metabolism. This study greatly enhances our understanding of how the cGMP/PKG activation system can be modulated in females with reduced sex hormone- paving the way for gender-selective targeting in patients with obesity and HFpEF.

Behavioral Modification Enhances the Benefits from Structured Aerobic and Resistance Training.

Behavioral modification (BM) is a strategy designed to sustain or restore well-being through effects such as enhanced relaxation, reduced stress, and improved sleep. Few studies have explored the role of BM delivered in the context of fitness programs for healthy adults. Thus, the purpose of this investigation was to examine whether BM combined with aerobic and resistance training programs would improve health and fitness measures more than the exercise training alone. Thirty-two healthy fitness club members (19 men) were randomized to receive a BM program (n=15) or an equal-attention (EA) control (n=17). BM consisted of twelve, 10-min education sessions between a trained fitness professional and the participant, coupled with weekly, individualized relaxation, stress reduction, and sleep improvement assignments. All participants engaged in 1 h of coached resistance training and remotely guided aerobic exercise thrice weekly for 12 weeks. Fitness measures (aerobic performance, body composition, muscle strength and endurance, lower-body power), sleep characteristics, and heart rate variability (HRV) were obtained at baseline and after the 12-week program. BM resulted in greater improvements in aerobic performance (increased maximum oxygen uptake, metabolic (lactate) threshold, and percent of maximum oxygen uptake at which metabolic threshold occurred), peak and average lower-body power, and body composition (decreased body fat percentage and fat mass) compared to EA. BM also positively influenced parasympathetic tone through increased High-frequency HRV. BM resulted in greater improvements in fitness measures, body composition, and heart rate variability compared with EA. These findings have intriguing implications regarding the role of BM in augmenting health and physical performance.

The benefits of nutritional counselling for improving sport performance.

It is well known that the synergy between physical activity and healthy eating habits is an important combination for the achievement of different objectives. However, recent studies in the literature focused mainly on the effect of this synergy on weight loss or different non communicable diseases. In this study, we aimed to investigate the effect of healthy eating, based on the Mediterranean diet, on physical performance of kickboxers and runners. Forty athletes were recruited from the University Sports Center of Bergamo. Twenty participants practiced kickboxing, an High Energy Expenditure Rate sport, whereas twenty subjects practiced half marathon, a typical High Energy Expenditure Volume sport. Kickboxers and runners were randomly divided into two sub-groups of ten subjects each: one was the control group (CG) and one the nutritional counselling group (NCG), in which subjects were instructed to follow a nutritional counselling. At the baseline, runners started with greater VO2max and lower resting metabolic rate compared to kickboxers. After three months of controlled diet and training, kickboxers in NCG improved their results in Counter Movement Jump (CMJ) Test (P=0.015) and squat (P=0.012). Moreover, athletes had a decrease in body fat percentage (P=0.008). Runners in NCG, had a significant VO2max (P=0.007) increase and a reduction in body fat percentage (P=0.002). They also showed an increase of squat (P=0.012) and CMJ test (P=0.024). Significant benefits were achieved in all groups of athletes, but results were maximized by training plus nutritional counselling.

The Relationship between Bone Mineral Accrual and Changes of Body Composition in Competitive Girl Runners

Low bone density is a complication of a long-term strict weight control during adolescence in women. PURPOSE: To assess whether decrease in percent body fat (%BF) is associated with an impaired bone mineral accrual in girl runners. METHODS: Consecutive 22 freshmen girl runners (15y/o, 158cm, 45kg) during 7 years in competitive high school teams were evaluated over 2 years of training. DXA was performed at the preparatory phase (baseline) and repeated after 23 ± 2 months (follow-up). The runners were divided into 2 groups; negative (DEC, n=11) or positive (GAIN, n=11) changes of %BF (Δ%BF) during the period. The effect of the period and the group on the changes in bone mineral content (BMC) and density (BMD) of total body less head and z-score were analyzed by 2-way repeated measures ANOVA. As for lean soft tissue mass (LSM) and fat mass (FM), paired t-test was used to compare between baseline and follow-up. Bivariate correlation analysis was used to examine the relationship between bone mineral accrual (ΔBMC and ΔBMD) and Δ%BF as well as the changes of FM (ΔFM) and LSM (ΔLSM). Written informed consent was obtained from the runners and their parents. P<0.05 was considered as statistically significant. RESULTS: %BF changed from 17.4 to 14.3 (DEC) and 15.0 to 18.4 % (GAIN). The period had significant effects on BMC, BMD, and z-score without interactions. Contrast showed significant increases in those variables, while the group of Δ%BF had no significant effect, indicating the values of DEC and GAIN were similarly increased; 1.57 to 1.64 and 1.66 to 1.77 kg, 0.98 to 1.00 and 1.00 to 1.03 g/cm2, and -0.25 to -0.20 and 0.04 to 0.22, respectively. The DEC runners gained LSM (34.2 to 36.1 kg) and reduced FM (7.7 to 6.4 kg) significantly, while the GAIN runners significantly increased FM (6.9 to 9.0 kg) without LSM change (36.6 to 37.0 kg). Neither Δ%BF nor ΔFM, but ΔLSM was significantly correlated with ΔBMC (r=0.45) and ΔBMD (r=0.55). CONCLUSIONS: Bone mineral was equally accrued among the runners of which %BF increased or decreased, where the accretion was associated with LSM gain. Competitive distance runners would develop leanness by not only losing FM but also gaining LSM (i.e., skeletal muscle) along with long-term exercise training. This would ameliorate an impairment of bone mineral acquisition by strict weight control.

Intentions Matter When it Comes to Body Composition Changes in DIII Athletes Over Summer Break

In Division III, coaches cannot require athletes to report summer workouts, but can suggest what should be done to be ready the upcoming season. Coaches also cannot cut an athlete based on knowledge of a lack of summer workouts. PURPOSE: To determine whether athlete intentions lead to efficacious outcomes in DIII athletes over summer break. It was hypothesized that due to lack of accountability, body composition intentions over summer break would not be achieved. METHODS: Fifty-one student athletes (32 women, 19 men; 20 &#177; 1 years old) had their body composition assessed in May in addition to their intention(s) regarding body composition changes over summer break (increase muscle mass and/or decrease fat mass or no change). Body composition was again assessed in August of the following school year. RESULTS: Only an intention to increase muscle mass or decrease body fat mass led to no significant change in either variable. When athletes had the combined intention of increasing muscle mass and decreasing fat mass, a significant decrease in body fat percentage was observed (-1.8 &#177; 2.3%; p = 0.017). Independently, the increase in muscle mass (+1.33 &#177; 2.3kg; p = 0.063) and decrease in fat mass (-1.1 &#177; 2.2kg; p=0.094) were not significant. CONCLUSIONS: Thus, these data suggest in order to achieve a decrease in fat mass, that has a significant impact on percent body fat, this intention should be combined with the intention to increase muscle mass. Additionally, singular intentions did not evoke intended body composition changes.

Hypocaloric High Fat and High Carbohydrate Diets on Visceral Adipose Tissue and Body Composition

INTRODUCTION: Excess visceral adipose tissue (VAT) is strongly associated with increased cardiometabolic risks. High-fat (HF) diets are a popular method for improving body composition. PURPOSE: To determine the role of HF diets in body composition and VAT. METHODS: In a randomized, cross-over design, 12 healthy, sedentary individuals were assigned either to a HF or HC diet trial with a 20% reduction in total caloric intake from their typical diet. Participants maintained their 1st assigned diet for 2 weeks followed by a 1-week washout period where they consumed their typical diet. After the 1-week washout period, participants began the opposite diet trial (either HF or HC) for 2 weeks. The HF diet consisted of 70% fat and 30% carbohydrate and protein, with a limit of 50 grams of carbohydrate. The HC diet consisted of 70% carbohydrate and 30% fat and protein. Body composition including VAT in mass and volume were determined using dual-energy x-ray absorptiometry. RESULTS: Total body mass decreased up to 1.5 kg from the pre-intervention (78.07±17.36 kg) following either the HF (76.63±15.99 kg) or HC (76.24±15.71 kg) trial, yet it was not statistically significant. VAT in mass and volume decreased following either the HF or HC diet from the pre-intervention (429.57±225.43g and 464.42±244.02cm3). However, the magnitude of change in VATmass and VATvolume was greater in the HF diet (374±159.59g and 404.14±172.54cm3) than the HC diet (388.71±184.73g and 420.42±199.93cm3) although it was not statistically significant. Notably, percent body fat decreased only following the HF diet (pre-intervention: 29.70±9.75, HF: 27.65±10.55, and HC: 29.15±11.43%). CONCLUSION: Although a short-term hypocaloric diet with either HF or HC did not yield a significant change in body composition, there was a strong trend showing that hypocaloric diets, whether HF or HC, can lower total body weight. HF diets though may be more effective than HC at decreasing body fat percentage and VAT. Our study only looked at changes after two-week dietary interventions in healthy sedentary individuals. Thus, future studies examining long term effects of HF diets in a variety of subject populations, including obese people, may provide more accurate information regarding a role of HF diets in body composition and visceral adipose tissue.

SAT-111 Reversal of Nonalcoholic Fatty Liver Disease with Bariatric Surgery in South Asians: Does the Type of Surgery Matter?

Nonalcoholic fatty liver disease (NAFLD) is a common complication of obesity with prevalence rates of 65 - 85% in obese individuals. It can be associated liver cell injury eventually leading to cirrhosis. Weight loss is the primary modality of treatment of NAFLD which can be difficult to achieve and maintain in a majority of patients. Bariatric surgery has been shown to reverse NAFLD but the type of bariatric surgery that is most effective, especially in South Asian patients is not clear. In this study we aimed to compare the effectiveness of laparoscopic sleeve gastrectomy (LSG) versus laparoscopic mini gastric bypass (LMGB) in reversing NAFLD in obese Sri Lankans. We did a retrospective analysis of medical records of 155 obese patients who underwent LSG and LMBG at Colombo South Teaching Hospital, Sri Lanka. Overall 114 (73.5%) and 41 (26.5%) patients underwent LSG and LMBG respectively. Among patients who underwent LSG and LMGB, there was no statistically significant difference in the baseline body weight (112.5 ± 19.5 vs 120.2 ± 29.4 kg), BMI (44.7 ± 6.1 vs 45.9 ± 8.0 kg/m2), waist circumference (WC) (female: 118.9 ± 11.2 cm vs 117.9 ± 9.0 cm, male: 125.5 ±14.7 cm vs 130.7 ±15.9 cm) and body fat percentage (BFP) (female: 45.9 ± 3.1% vs 43.1 ± 9.5%, male: 40.9 ± 6.8% vs 39.4 ± 1.6%). There was no significant difference between patients who underwent LSG and LMBG, in decrease in weight (24.7 ±7.1 kg vs 32.6 ±14.7 kg, p=0.12) and decrease in BMI (10.0 ±2.9 kg/m2 vs 12.0 ±4.2 kg/m2, p=0.08) at 6 months post-procedure as compared to baseline, although LMBG showed a trend towards greater benefit. There was no statistically significant difference in the decrease in WC (19.0 ±9.9 cm vs 20.8 ±5.8) and decrease in BFP (7.4% ±5.8 vs 10.8% ±5.6). Overall 88.4% of patients had NAFLD by ultrasound scan (USS) imaging criteria. Patients with LSG and LMBG did not show a significant difference in baseline AST (31.8 ±21.1 vs 26.8 ±11.6 U/L, p>0.05) and ALT (41.1 ±30.3 vs 35.8 ±25.7, p>0.05). At 6 months post procedure, AST (21.6 ±8.1 vs 25.0 ±13.9 U/L, p=0.32) and ALT (19.1 ±9.4 vs 26.9 ±11.0 U/L, p<0.05) levels were lower in patients with LSG than patients with LMBG, although only ALT values reached statistical significance. Thus LSG showed a greater degree of AST (32.1% vs 6.7%, p<0.05) and ALT (53.5% vs 24.9%, p=0.001) reduction compared to LMBG. At 6 months post-procedure, patients who underwent LSG had less patients with elevated AST (4.4% vs 11.1%) and ALT (4.4% vs 12.5%) as compared to LMBG. Overall LSG showed a higher rate of complete reversal of NAFLD (75.0% vs 44.4%) and improvement of the grade of NAFLD (91.7% vs 66.7%) on USS imaging when compared with LMBG. In conclusion, our study reveal that LSG has a more favorable effect on complete reversal and improvement of NAFLD when compared with LMBG. This effect seems to be independent of weight loss. Thus LSG should be considered ahead of LMBG when bariatric surgery is planned for obese patients with NAFLD.

Efficacy of a Health Promotion Guidance Program Applied to the Police of São Paulo City

: The health promotion efficacy of a dietary regimen and physical activity guidance program applied to the Sao Paulo state military ppre-obese policemen exhibitedolice working in Sao Paulo city was investigated. The guidance program consisted of the delivery of a 10-minute talk on healthy nutritional habits and the beneficial effects of a regular physical activity practice for each volunteer personally. The physical fitness parameters related to the health of the volunteers were evaluated before and eight weeks after the interventional program. The study included 58 policemen working in Sao Paulo city, aged 34.9 ± 0.8 years (mean ± SEM). The application of the guidance program could decrease body fat percentage (BFP) (by 5.7%), abdominal circumference (ABC) (by 1.1%), and systolic blood pressure (SBP) (by 2.4%), and increase flexibility (FLEX) (by 8.8%) and abdominal resistance (ABR) (by 5.2%). A change in physical activity behavior was also reported. Increases in the number of volunteers in very active (VA) (3.45%), active (ACT) (10.35%), and irregular active A (IRA) (5.17%) groups, and reductions in irregular active B (IRB) (13.79%) and sedentary (SED) (5.17%) groups were found. The policemen were classified (before-after) as obese (29.3% - 24.1%) and pre-obese (39.7% - 43.1%). Foty-three percent of pre-obese policemen exhibited more daily physical activity after the guidance program implementation. The guidance program was effective in increasing the adherence of pre-obese policemen to the physical activity practice, reduced the percentage of body fat and abdominal circumference, and improved lower limbs flexibility and abdominal muscle resistance.

Evaluación del estado de nutrición, glucosa capilar, presión arterial e insatisfacción corporal en una población de artesanos indígenas mexicanos que acuden a una feria universitaria anual de artesanías

&lt;p&gt;Las enfermedades crónicas no transmisibles (ecnt), especialmente la obesidad y la &lt;em&gt;diabetes mellitus &lt;/em&gt;tipo 2 (dm2), son problemas serios de salud pública en nuestro país; los grupos más desfavorecidos socialmente son los más afectados. Con el objetivo de conocer el estado de nutrición, la presión arterial, glucosa capilar y la insatisfacción corporal, se invitó a los artesanos indígenas que participaron en las ferias anuales universitarias de artesanías a realizar una evaluación en la Clínica de Nutrición de la Universidad Iberoamericana de la Ciudad de México. Al final de cada evaluación se brindaron recomendaciones nutricias y de actividad física a los artesanos que de manera voluntaria participaron. Se realizaron 341 evaluaciones en cohortes de 6 años con-secutivos. Se encontró una frecuencia combinada de sobrepeso y obesidad similar a la prevalencia nacional, así como un aumento en la frecuencia de hipertensión arterial, diabetes y prediabetes a través de los años. Se observó una disminución significativa en el porcentajede grasa corporal en aquéllos que tuvieron dos y cinco intervenciones, lo cual señala la importancia de dar seguimiento a la atención de esta población. En cuanto a insatisfacción corporal, ésta aumentó, observándose un mayor deseo por siluetas más delgadas y una disminución hacia siluetas más robustas, lo cual pudiera reflejar la influencia de los modelos estéticos promovidos por los medios de comunicación en esta población. Es importante considerar los factores socioculturales para el diseño de futuras intervenciones en grupos vulnerables.&lt;/p&gt;

¡Viva Maryvale!: A Multilevel, Multisector Model to Community-Based Diabetes Prevention

Latino communities are disproportionately affected by type 2 diabetes and experience disparities in access to diabetes prevention programs. The purpose of this study was to test the preliminary efficacy of a culturally grounded, diabetes prevention program for high-risk Latino families delivered through an integrated research-practice partnership. The integrated research-practice partnership was established in a predominantly Latino community and consisted of a Federally Qualified Health Center, a YMCA, an accredited diabetes education program, and an academic research center. Data were collected and analyzed from 2015 to 2018. Latino families consisting of a parent with an obese child between age 8 and 12 years. The 12-week lifestyle intervention included nutrition education and behavioral skills training (60 minutes, once/week) and physical activity classes (60 minutes, three times/week) delivered at a YMCA. Outcomes included measures of adiposity (BMI, waist circumference, and body fat); HbA1c; and weight-specific quality of life. Over the course of the 2-year project period, 58 families (parents n=59, children n=68) were enrolled with 36% of parents and 29% of children meeting the criteria for prediabetes at baseline. Feasibility and acceptability were high, with 83% of enrolled families completing the program, 91% of the intervention sessions attended, and 100% of families stating they would recommend the program. The intervention led to significant decreases in percentage body fat among parents (46.4% [SD=10.8] to 43.5% [SD=10.5], p=0.001) as well as children (43.1% [SD=8.0] to 41.8% [SD=7.2], p=0.03). Additionally, HbA1c was significantly reduced in parents (5.6% [SD=0.4] to 5.5% [SD=0.3], p=0.03), and remained stable in children (5.5% [SD=0.3] vs 5.5% [SD=0.3], p>0.05). Significant improvements in quality of life were reported in parents (64.6 [SD=15.8] to 71.0 [SD=13.7], p=0.001) and children (69.7 [SD=15.8] to 72.6 [SD=13.7], p=0.05). These findings support the preliminary efficacy of an integrated research-practice partnership to meet the diabetes prevention needs of high-risk Latino families within a vulnerable community.

PO-122 Influence of Winter Training on Physiological and Biochemical Indexes of Bicyclist

Objective The research took the bicyclists in Zhejiang for preparing of the Thirteenth National Games in winter training as the subjects. Through physiological and biochemical index of testing during the winter training, we attempted to find out some rules or problems by exploring the characteristics of their training during winter training, Reached on body function and the training intensity of athletes for effective monitoring and adjustment effect during winter training, and to provide a reference for the development of scientific in bicycle training.&#x0D; Methods During the long term bicycle training, some physical fitness evaluation indices includingVO2max,anaerobic power,body composition,Hb,Bun,CK,T and NEUT% were tested and analyzed systematically. Master the bike athletes body function changes during the winter training, and discuss the relationship between these indexes and body function condition.&#x0D; Results VO2 max, VO2 max relative value almost no change during the winter training; The Large Anaerobic work, 30s average anaerobic work and an body composition indicators no significant difference (p &lt; 0.05), but had a significant change. Hb, Bun, CK,T,NEUT% based standard value in the normal range, throughout the winter training period, Hb, BUN and CK, T, NEUT % has experienced cyclical changes along with the change of sports load: Hb, T at the beginning of the winter training has a downward trend, CK and NEUT % in the early part of the winter training has a rising trend, but as for the winter training gradually restored, BUN rising during the winter training, two weeks before the end of winter training to get down.&#x0D; Conclusions 1, the pros and cons of aerobic capacity is not the main factors influencing the cycling short athlete special performance, but of eliminating anaerobic lactic acid after training to play an active role, aerobic ability training should be strengthened.&#x0D; 2, anaerobic metabolism energy is the important factors that affect cycling short athlete sport result, peak power and 30s average power to scientific evaluation of the athlete's training effect.&#x0D; 3, decreased body fat percentage and lean body mass increase, to improve the athlete special scores play a positive role.&#x0D; 4, during the winter training athletes Hb, CK, T, NEUT % changes over motion load, NEUT % can be used as auxiliary training monitoring indexes of female athletes on the biochemical indexes of the sensitivity is higher than male athletes.&#x0D; 5, in the case of lean body mass is not fall, blood urea to maintain at a high level of cycling short athletes may not bring much impact performance.&#x0D; 6, Because of the mobilization can bear the load and strength are not the same, the same load and intensity produced by the reflect function will not the same, further analysis is needed to combined with physiological and biochemical indexes and individual training plan situation carries on the comprehensive consideration, so as to improve the accuracy of measurement analysis.

Futsal improve body composition and cardiorespiratory fitness in overweight and obese children. A pilot study

Abstract Aims: The aim of this study was to verify body composition, cardiorespiratory fitness, and biochemical markers of prepubertal overweight and obese boys to a 16-week futsal training program. Methods: Sixteen boys (age: 7-10 y, body mass index>thanat 95th percentileaccording to Center for Disease Control and Prevention; 35.5±7.4 percent fat) participated to futsal training program. The assessment of body composition was estimated using skinfold thickness, and the following variables were evaluated: total body mass, body mass index, body fat percentage, and lean body mass. Aerobic fitness measurementwas performed by gas exchange analysis in treadmill. In addition, an evaluation of the biochemical profile was conducted: triglycerides, total cholesterol, low density lipoprotein cholesterol, high-density lipoprotein cholesterol, plasma concentrations of glucose, and insulin. The futsal intervention included 60-min sessions performed two times/week. The mean intensity during training was between 57 to 88% of maximal heart rate of the age-predicted. Individual portable heart rate monitor controlled training intensity. Results: Significant increases in total body mass (4%), height (3%), lean body mass (8%), and significant 6%-decrease in body fat percentage was observed. Body mass index remained unchanged. Maximal oxygen uptake was elevated (p<0.018) by 11%. Biochemical markers were not modified after intervention. No association was found between body composition and metabolic variables. The effect size of futsal training on most variables was small (<0.5). Conclusion: Controlled intensity and adherence to this 16-week futsal training program were determinant to enhance body composition, and cardiorespiratory fitness in this group of prepubertal boys.
