Our results show that supplement intake in people exercising in gyms is high and is usually self-prescribed. We emphasize that the use of dietary supplements must be always done under the supervision of a specialist (physician or nutritionist).

This study aimed to estimate the prevalence of leisure-time physical activity and investigate its association with contextual characteristics of the social and physical environment in different socioeconomic statuses, using a household survey in Belo Horizonte, Minas Gerais State, Brazil (2008-2009). Leisure-time physical activity was measured by the International Physical Activity Questionnaire; and the social and physical environment by scales arising from perception of neighborhood attributes. Multilevel logistic regression analysis was performed separately for each socioeconomic status stratum. The overall prevalence of leisure-time physical activity was 30.2%, being 20.2% amongst participants of low socioeconomic status, 25.4% in the medium and 40.6% in the high socioeconomic status group. A greater perception of social cohesion was associated with increased leisure-time physical activity only amongst participants of the lowest socioeconomic status even after adjusting for individual characteristics. The results demonstrate the importance of social cohesion for the promotion of leisure-time physical activity in economically disadvantaged groups, supporting the need to stimulate interventions for enhancing social relationships in this population.

Our results do not support the hypothesis of an effect for occupational stress on urban employees' health behaviors.

The anthropometric and/or dietary profile of elite runners has been studied; however, little is known about the characteristics of recreational street runners. This study was aimed to characterize the nutritional profile of recreational runners from a sports club in Belo Horizonte, MG, Brazil, who were referred to a nutritional clinic of a local private college. The sample study was composed of 19 athletes, aged between 28 and 53 years. The diagnosis of the runners' nutritional status was obtained by assessment of their energy and macronutrients -carbohydrates (CHO), lipids (LIP), and proteins (PTN) consumption-through the 24-hour dietary recall (R24h), as well as analysis of their anthropometric profile. The results obtained from the dietary evaluation showed that according to the recommendations proposed by the DRIs (Dietary Reference Intakes), the distribution of energy among the macronutrients in both men and women was adequate: 48.1±9.2% (CHO), 29.6±7.2% (LIP) and 22.3±4.96% (PTN). However, when considering energy consumption in g/kg of body weight, the intake of CHO was low (3.54±1.45g/kg/d) and of PTN was high (1.7±0.57 g/kg/d) for this type of recreational exercise. Regarding total energy consumption, 89.5% of runners presented energy intake below the recommended values, resulting in daily caloric deficiency. Concerning the anthropometric evaluation, the average percentage of body fat (%G) for men and women was not statistically different and was considered adequate based on their age. Waist circumference (WC) and waist/hip ratio (WHR) of the studied group showed normal results and do not represent increased risk for cardiovascular diseases. In conclusion, the study indicates that although the athletes showed adequate caloric distribution of macronutrients, it was still not sufficient to meet the energy requirements of their modality, suggesting hence that continuous nutritional guidance is needed.

Exercise-induced muscular overload can trigger delayed onset muscle soreness (DOMS). DOMS is related to the indiscriminate use of analgesics and nonsteroidal anti-inflammatory drugs without proper guidance, decreased physical exercise adherence and degenerating sports performance, increased risk of injury, and reduced muscle strength and function. Dietary anthocyanins have been extensively studied as potential natural treatments for DOMS, but the indication, dosage, and form of use remain highly variable. Therefore, this review aims to synergize and present evidence relating to the effect of anthocyanins on DOMS in clinical studies. Notably, the results of anthocyanin supplementation for DOMS were found to be inconclusive. The use of protocols with lower anthocyanin doses yielded better results than those with high-dose supplements, suggesting that anthocyanin-rich foods are more accessible as therapeutic tools, leading to the conclusion that these foods could be used to prevent and treat DOMS. However, consumption protocols for this purpose are not yet well established, and the answer is dependent on the methodological quality of future studies.
