This study compares the effects of team-sport training, for sedentary men with lifestyle diseases, with fitness training in a pragmatic set-up in a community health centre (CHC). Thirty-two men in the fitness group (FiG) and 36 men in the team-sport group (TsG) completed the training and trained for 60–90 min, two times/week for 12–16 weeks. In FiG and TsG, mean heart rate (HR) during training was 73.2% and 74.5% of HRmax, respectively. Percentage of training time above 90%HRmax was 6 ± 9% and 10 ± 15% and the percentage of participants who spent > 10% of total training time with HR > 90%HRmax was 20% and 41%, in FiG and TsG, respectively. In FiG, total fat mass was reduced by 3.5%  (P<0.01), while performance in the 6 min walking test (6MWT) increased by 11%  (P<0.001). In TsG, total fat mass was reduced by 2.2%  (P<0.01), while 6MWT performance improved by 5%  (P<0.05). Between-group differences were observed for systolic BP (P=0.041) and mean arterial pressure (P=0.050) in favour of TsG and for sit-to-stand test (P=0.031) in favour of FiG. In conclusion, small-sided team sport is a worthy alternative to fitness training since the overall health effects are comparable, for example, improved balance and reduced fat mass. Team sport elicits high heart rates and improves cardiovascular health by reducing blood pressure, while fitness training improves sit-to-stand test performance related to activity of daily living.

Tenofovir Diphosphate

Abstract Background In this study, we evaluate associations between cumulative antiretroviral adherence/exposure, quantified using tenofovir diphosphate (TFV-DP) in dried blood spots (DBS), and human immunodeficiency virus (HIV)-related aging factors. Methods This is a cross-sectional analysis of younger (ages 18–35) and older (ages ≥60) persons with HIV (PWH) taking TFV disoproxil fumarate. Tenofovir diphosphate concentrations were quantified in DBS. Linear and logistic regression models were used to evaluate associations between TFV-DP and bone mineral density (BMD), physical function, frailty, and falls. Results Forty-five PWH were enrolled (23 younger, 22 older). Every 500 fmol/punch (equivalent to an increase in ~2 doses/week) increase in TFV-DP was associated with decreased hip BMD (−0.021 g/cm2; 95% confidence interval [CI], −0.040 to −0.002; P = .03). Adjusting for total fat mass, every 500 fmol/punch increase in TFV-DP was associated with higher odds of Short Physical Performance Battery impairment (score ≤10; adjusted odds ratio [OR], 1.6; 95% CI, 1.0–2.5; P = .04). Every 500 fmol/punch increase in TFV-DP was associated with slower 400-meter walk time (14.8 seconds; 95% CI, 3.8–25.8; P = .01) and remained significant after adjusting for age, lean body mass, body mass index (BMI), and fat mass (all P ≤ .01). Every 500 fmol/punch increase in TFV-DP was associated with higher odds of reporting a fall in the prior 6 months (OR, 1.8; 95% CI, 1.1–2.8; P = .02); this remained significant after adjusting for age, lean body mass, BMI, and total fat mass (all P &lt; .05). Conclusions Higher TFV-DP levels were associated with lower hip BMD, poorer physical function, and greater risk for falls, a concerning combination for increased fracture risk.

SummaryThis study was aimed at evaluating the relationship between visceral fat accumulation and plasma plasminogen activator inhibitor-1 (PAI-1) levels in healthy, obese men and women undergoing weight loss therapy. The subjects, 25 men and 25 premenopausal women, aged between 26 and 49 years, with an initial body mass index between 28 and 38 kg/m2, received a controlled diet for 13 weeks providing a 4.2 MJ/day energy deficit. Magnetic resonance imaging was used to measure visceral and subcutaneous abdominal fat. Our results show that before weight loss visceral fat was significantly correlated with PAI-1 in men (r = 0.45; p <0.05), but not in women (r = -0.15; ns). The association between visceral fat and PAI-1 in men remained significant after adjustment for age and total fat mass, and multiple linear regression analysis showed a significant independent contribution of visceral fat to plasma PAI-1 levels. Both visceral fat areas and PAI-1 levels decreased significantly with weight loss in both men and women. Changes in visceral fat area were related to changes in PAI-1 in women (r = -0.43; p = 0.05) but not in men (r = -0.01; ns); however, this association in women disappeared after adjustment for total fat mass. We conclude that there is a relationship between visceral fat and PAI-1 in obese men but not in obese women, and that PAI-1 levels decrease substantially (52%) by weight loss, but this change is not related to changes in visceral fat mass per se.

ObjectiveTestosterone therapy increases lean body mass and decreases total fat mass in aging men with low normal testosterone levels. The major challenge is, however, to determine whether the metabolic consequences of testosterone therapy are overall positive. We have previously reported that 6-month testosterone therapy did not improve insulin sensitivity. We investigated the effect of testosterone therapy on regional body fat distribution and on the levels of the insulin-sensitizing adipokine, adiponectin, in aging men with low normal bioavailable testosterone levels.DesignA randomized, double-blinded, placebo-controlled study on 6-month testosterone treatment (gel) in 38 men, aged 60–78 years, with bioavailable testosterone <7.3 nmol/l, and a waist circumference >94 cm.MethodsCentral fat mass (CFM) and lower extremity fat mass (LEFM) were measured by dual X-ray absorptiometry. Subcutaneous abdominal adipose tissue (SAT), visceral adipose tissue (VAT), and thigh subcutaneous fat area (TFA) were measured by magnetic resonance imaging. Adiponectin levels were measured using an in-house immunofluorometric assay. Coefficients (b) represent the placebo-controlled mean effect of intervention.ResultsLEFM was decreased (b=−0.47 kg, P=0.07) while CFM did not change significantly (b=−0.66 kg, P=0.10) during testosterone therapy. SAT (b=−3.0%, P=0.018) and TFA (b=−3.0%, P<0.001) decreased, while VAT (b=1.0%, P=0.54) remained unchanged. Adiponectin levels decreased during testosterone therapy (b=−1.3 mg/l, P=0.001).ConclusionTestosterone therapy decreased subcutaneous fat on the abdomen and lower extremities, but visceral fat was unchanged. Moreover, adiponectin levels were significantly decreased during testosterone therapy.

AbstractObesity has previously been thought to protect bone since high body weight and body mass index are associated with high bone mass. However, some more recent studies suggest that increased adiposity negatively impacts bone mass. Here, we aimed to test whether acute loss of adipose tissue, via adipocyte apoptosis, alters bone mass in age-related obese mice. Adipocyte apoptosis was induced in obese male FAT-ATTAC mice through AP20187 dimerizer-mediated activation of caspase 8 selectively in adipocytes. In a short-term experiment, dimerizer was administered to 5.5 month-old mice that were terminated 2 weeks later. At termination, the total fat mass weighed 58% less in dimerizer-treated mice compared with vehicle-treated controls, but bone mass did not differ. To allow for the detection of long-term effects, we used 9-month-old mice that were terminated six weeks after dimerizer administration. In this experiment, the total fat mass weighed less (− 68%) in the dimerizer-treated mice than in the controls, yet neither bone mass nor biomechanical properties differed between groups. Our findings show that adipose tissue loss, despite the reduced mechanical loading, does not affect bone in age-related obese mice. Future studies are needed to test whether adipose tissue loss is beneficial during more severe obesity.

Background: As the epidemic of obesity in the United States steadily worsens, black women are disproportionately affected. Diminished insulin sensitivity has been linked with obesity and heightened risk of subsequent type 2 diabetes (T2D) and cardiovascular disease (CVD). Hypothesis: We propose that a decrease in fat mass achievable by weight loss intervention at the worksite improves insulin sensitivity in overweight black women. Methods: Fifty-four overweight black women [age 45±10 years (mean±SD), BMI range 25.9 to 54.7 kg/m 2 ] completed a 6-month program that included web-based nutrition information and/or dietitian counseling and access to exercise rooms near their work areas. All participants were advised to reduce daily caloric intake by 500 kcal and instructed to increase daily activity by 5,000 steps, measured by pedometer, above baseline readings. The following measurements were performed: weight, total fat mass by dual-energy X-ray absorptiometry, and insulin sensitivity index (S I ) calculated from the minimal model. Repeat of all measurements was performed at 6 months. Results: Baseline S I (median 3.0 liter/mU -1 •min -1 , range 0.74 to 7.58 liter/mU -1 •min -1 , with lower values signifying insulin resistance) was negatively associated with fat mass (r= -0.584, P<0.001) independent of age. Significant reductions in weight (92.6±18.1 to 91.1±18.9 kg, P<0.01) and fat mass (40.8±12.4 to 39.4±12.6 kg, P<0.01) were determined for subjects completing the program. Reduction in fat mass following completion of the program was associated with an increase in S I (r= -0.293, P=0.032). When analyzed by tertiles of fat mass change (Figure), compared to the tertile with net fat mass gain (far left bar), the two tertiles with net fat mass loss had significantly improved insulin sensitivity (higher S I ). Conclusions: Even modest fat mass reduction in overweight non-diabetic black women with a combination of diet and exercise can improve insulin sensitivity, which has the potential to reduce or delay the onset of T2D and CVD.

INTRODUCTION: In healthy men, body weight and total fat content increase with advancing age, while serum testosterone levels decrease. In order to elucidate whether a causal relationship between these phenomena exists, we investigated the influence of testosterone or human chorionic gonadotrophin substitution on body mass index (BMI), total fat mass and serum leptin in testosterone-treated and untreated hypogonadal patients in comparison with ageing eugonadal men. METHODS: In a cross-sectional study, the inter-relationships of body weight, total fat mass, serum sex hormones and leptin were analysed in untreated hypogonadal men (n=24; age 19-65 years), treated hypogonadal men (n=61; age 20-67 years) and healthy eugonadal men (n=60; age 24-78 years). Total fat mass was assessed by bioimpedance measurement. Univariate and multiple linear regression analysis was used to detect possible differences. RESULTS: In eugonadal men, serum testosterone levels decreased with advancing age (correlation coefficients: r=-0.71; P<0.0001), while BMI (r=0.39; P=0.002), total fat content (r=0.51; P<0.0001) and leptin (r=0.48; P<0.0001) increased significantly. In untreated hypogonadal patients, an increase in BMI (r=0.50; P=0.013) and total fat mass (r=0.41; P=0.044) was also observed with advancing age. However, in substituted hypogonadal patients, no age-dependent change in BMI (r=0.067; P=0.606), body fat content (r=-0.083; P=0.522), serum testosterone (r=-0,071; P=0.59) or serum leptin (r=-0.23; P=0.176) was found. CONCLUSION: Since testosterone-substituted older hypogonadal men show BMI and fat mass similar to those of younger eugonadal men and since non-treated hypogonadal men are similar to normal ageing men, testosterone appears to be an important factor contributing to these changes. Thus ageing men should benefit from testosterone substitution as far as body composition is concerned.

Background: There has been no previous study that has investigated the effect of a low glycemic index (LGI) diet with local recipes of South Indian cuisine on the body fat composition using dual-energy X-ray absorptiometry (DXA). Truncal obesity has been associated with the risk of metabolic disorders and cardiovascular diseases. Aim: The aim of this study was to examine the effect of a low GI diet on glycemic control and body composition in people with type 2 diabetes in South India. Method: This was a prospective and randomized controlled study that was conducted over a period of 24 weeks. A total of 40 participants were recruited from the Department of Endocrinology and Diabetes Outpatient in Kerala, South India. All the patients had type 2 diabetes and were randomly assigned and given advice and instructions to follow either a low GI diet plan (n = 18) or their usual diet, which served as control (n = 18). The advice was reinforced throughout the study period. Dietary compliance was evaluated based on a 24 h dietary recall at weeks 3, 11, 12, 18, 23, and 24. The age of the subjects ranged from 35 to 65 years. Anthropometric, body composition, and cardio-metabolic parameters were measured according to standard procedures. T-tests were conducted to compare differences between intervention and control groups and the Pearson correlation coefficient was used to evaluate associations between the variables. Results: There were significant reductions (p < 0.05) in the low GI diet compared to the control group with respect to weight, body mass index (BMI), and triceps skinfold thickness. Similarly, significant reductions were observed in the low GI diet group with respect to region, total fat, android, and gynoid fat mass and the differences between the groups were significant at p < 0.05. There was also a positive correlation between BMI and android fat mass (r = 0.745), total fat mass (r = 0.661), total truncal mass (r = 0.821), and truncal fat (r = 0.707). There was a significant reduction in glycated hemoglobin in the low GI diet group compared to the control group at p < 0.05. Conclusion: This study has demonstrated that there was a significant reduction (p < 0.05) of truncal obesity and glycated hemoglobin in patients with type 2 diabetes on a local diet of South Indian cuisine with low GI compared with the control.

Response To Exercise

Obesity is a major risk factor for metabolic disease. Growth differentiation factor 15 (GDF15) has shown promise as a weight loss agent for obesity in animal studies. In healthy lean humans, fasting plasma GDF15 increases after acute exercise. However, the role of GDF15 in human obesity and the response of plasma GDF15 to exercise training in patients with obesity is unknown. Here, 24 sedentary volunteers with obesity [age: 65 ± 1 yr; body mass index (BMI): 35.3 ± 0.9 kg/m2] participated in a supervised 12-wk aerobic exercise intervention: 1 h/day, 5 days/wk at ~85% maximum heart rate with controlled isocaloric diet. As a result, plasma GDF15 was significantly increased (PRE: 644.1 ± 42.6 pg/ml, POST: 704.4 ± 47.2 pg/ml, P < 0.01) after the exercise intervention. Inconsistent with animal models, ΔGDF15 was not correlated with change in weight, BMI, or resting energy expenditure. However, ΔGDF15 was correlated with a reduction in total fat mass ( P < 0.05), abdominal fat mass ( P < 0.05), and android fat mass ( P ≤ 0.05). Participants with a positive GDF15 response to exercise had increased total fat oxidation (PRE: 0.25 ± 0.05 mg·kg−1·min−1, POST: 0.43 ± 0.07 mg·kg−1·min−1, P ≤ 0.05), metabolic flexibility [PRE: −0.01 ± 0.01 delta respiratory quotient (RQ), POST: 0.06 ± 0.01 delta RQ, P < 0.001], and insulin sensitivity (PRE: 0.33 ± 0.01 QUICKI index, POST: 0.34 ± 0.01 QUICKI index, P < 0.01), suggesting a link between GDF15 and fat mass loss as well as exercise-induced metabolic improvement in humans with obesity. We conclude that the exercise-induced increase in plasma GDF15 and the association with reduced fat mass may indicate a role for GDF15 as a therapeutic target for human obesity.
