Poor adherence to physical activity programmes during pregnancy is a serious national issue, one that has detrimental effects on a large percentage of the population. Not only does a lack of activity result in a decrease in quality of life for women during term, but the effects can carry over well after pregnancy, potentially leading to increased morbidity and mortality. What's more, reduced prenatal activity can cause adverse effects on the foetus, with impairments seen in physical health as well as cognition. Accordingly, the purpose of this paper is twofold: first, to examine the socio-demographic data and psychosocial influences that modify exercise behaviours in pregnant women and, second, to make recommendations as to effective intervention strategies that can be adopted by health and fitness professionals to help improve maternal exercise participation and adherence.

Study aim: To determine the effects of mint extract on muscle pain and blood lactate levels after a 400-m run.Material and methods: A group of 16 physical education students (mean age 21.81 ± 2.13 years) volunteered to participate in the study. The subjects were randomly assigned into 3 groups: mint, placebo or control. The mint group was given orally mint extract (5 ml/kg of body mass) and the placebo group was given unsweetened tea (5 ml/kg) in a double-blind fashion and cross-over design one hour before a 400-m running test. Subjects in the control group remained untreated. The effect of mint extract on muscle pain was recorded by an inquiry; blood lactate levels were measured after the running test.Results: Oral administration of mint extract significantly (p<0.01) decreased blood lactate concentrations but muscle pain levels remained unchanged in all groups.Conclusions: Oral administration of mint extract may have a beneficial effect on blood lactate clearance and therefore may increase athletic performance.

Omega-3 (n-3) fatty acids, and the long-chain n-3 derivatives eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in particular, have been extensively researched for their nutritive effects. Among their many purported benefits, n-3 acids have been implicated as positive mediators of cardiovascular health and body composition. It has therefore been speculated that supplementation may enhance the beneficial effects of physical activity, potentiating greater reductions in body fat and improvements in exercise performance. This paper has three objectives: first, to assess the theoretical basis for a synergistic ef-fect when n-3 supplementation is combined with exercise; second, to review the literature as to specific findings on the subject and third, to make relevant conclusions and recommendations for future research.

Obesity, a disorder of body composition, is defined by a relative or absolute excess of body fat. In general adult population, obesity has been associated with a diverse array of adverse health outcomes, including major causes of death such as cancer, diabetes, cardiovascular disease, as well as functional impairment from problems such as osteoarthritis and sleep apnea. Ghrelin is a newly discovered peptide hormone which plays an important role in obesity. It is a powerful, endogenous orexigenic peptide and has a crucial function in appetite regulation, as well as short – and long-term energy homeostasis. In the presence of increased obesity, decreased physical activity, and high food consumption, the relationship between exercise, appetite, food intake and ghrelin levels has important implications. In this review, we discuss the effect of acute and chronic exercise performance on appetite, food intake and ghrelin and their relationships.
