Vitamin B6 and exercise.

Abstract

This paper presents an overview of vitamin B6 and exercise, including the role that vitamin B6 plays in gluconeogenesis and glycogenolysis and changes in vitamin B6 metabolism during exercise. The dietary vitamin B6 intakes of athletes are also reviewed. Most studies report that male athletes have adequate dietary intakes of vitamin B6, whereas some females, especially those with low energy intakes, appear to have low vitamin B6 intakes. Few studies have assessed the vitamin B6 status of nonsupplementing athletes using the recommended status criteria. The role that vitamin B6 may play in attenuating the rise in plasma growth hormone observed during exercise is also reviewed. Finally, recommendations are given for further research in the area of vitamin B6 and exercise.

Creating a robust public health infrastructure for physical activity promotion.

The essential role of physical activity both as an independent protective factor against numerous common chronic diseases and as a means to maintain a healthy weight is gaining increasing scientific recognition. Although the science of physical activity promotion is advancing rapidly, the practice of promoting physical activity at a population level is in its infancy. The virtual absence of a public health practice infrastructure for the promotion of physical activity at the local level presents a critical challenge to control policy for chronic disease, and particularly obesity. To translate the increasing evidence of the value of physical activity into practice will require systemic, multilevel, and multisectoral intervention approaches that build individual capability and organizational capacity for behavior change, create new social norms, and promote policy and environmental changes that support higher levels of energy expenditure across the population. This paper highlights societal changes contributing to inactivity; describes the evolution and current status of population-based public health physical activity promotion efforts in research and practice settings; suggests strategies for engaging decision makers, stakeholders, and the general public in building the necessary infrastructure to effectively promote physical activity; and identifies specific recommendations to spur the creation of a robust public health infrastructure for physical activity.

Physical activity, cardiorespiratory fitness and insulin resistance: a short update.

PURPOSE OF REVIEW: High levels of cardiorespiratory fitness and/or habitual physical activity are associated with reduced risk of cardiovascular disease. The responsible mechanisms are multifarious, but effects on insulin sensitivity are likely to play an important role. The purpose of this review is to highlight some recent evidence on the interrelationships between physical activity, fitness, obesity, genotype and insulin resistance. RECENT FINDINGS: Effects on cardiorespiratory fitness and abdominal obesity are both likely to contribute to the insulin-sensitizing effects of regular physical activity. Recent data suggest that at least in older adults, the intensity of an exercise intervention may influence the magnitude of changes in insulin sensitivity, and emerging data suggest that individual changes in insulin sensitivity following an exercise programme may, in part, be influenced by genotype. SUMMARY: Increasing physical activity reduces insulin resistance. As both intensity of exercise and genetic factors may modulate the magnitude of this effect, current physical activity for health guidelines that emphasize engagement in moderate-intensity physical activity in a 'one-size-fits-all' approach may need revision in the future to optimize the potential benefits accrued from individuals becoming more active.
