Metabolism: The interaction of exercise with metabolism was the second highest occurrence, another expected www.selleckchem.com/products/Y-27632.html outcome of the literature search. Six papers were devoted to human studies, seven to animal models. Navalta et al. 26 endeavored to determine whether cognitive awareness of carbohydrate beverage consumption affects exercise-induced lymphocyte apoptosis, irrespective of actual carbohydrate intake. Carbohydrate supplementation during aerobic exercise generally protects against the immunosuppressive effects of exercise but it is not currently known whether carbohydrate consumption or simply the knowledge of carbohydrate consumption also has that effect. They claim that neither carbohydrate nor placebo supplementation altered the typical lymphocyte apoptotic response following exercise.

While carbohydrate supplementation has an immune-boosting effect during exercise, it appears that this influence does not extend to the mechanisms that govern exercise-induced lymphocyte cell death. As seen earlier, the relation between metabolic syndrome and cardiovascular risk was studied by Marcon et al. 24 who conclude that a supervised exercise program of low intensity and frequency might interfere positively in cardiometabolic risk in individuals with morbid obesity. The ever present interaction of AIDS with nutrition was the subject matter of Souza et al. 27 , who prospectively evaluated eleven HIV affected patients living vs. 21 controls older than 60 years and without prior regular physical activity. A one-year progressive resistance exercise program was instituted.

Initially, HIV patients were lighter and weaker than controls, but their strength increased faster nullifying initial differences. These effects were independent of gender, age or baseline physical activity. HIV patients improved fasting glucose levels. They conclude that resistance exercise safely increased the strength of older patients living with HIV adults, allowing them to achieve performance levels observed among otherwise healthy controls and claim that resistance exercise should be prescribed to HIV afflicted adults. On a different note, Faria Coelho et al. 28 investigated the effects of L-carnitine supplementation, on the resting metabolic rate and oxidation of free fatty acids under rested or exercised conditions in 21 overweight active volunteers.

They conclude that carnitine supplementation caused no changes in the variables analyzed in this study. Two papers look at lipidic profile of normal fit individuals undergoing exercise. Zanella et al. 29 evaluated whether lipid profile, apolipoprotein A-1 and malondialdehyde have any relationship with physical exercise by comparing footballers with their relatives and with sedentary controls. Footballers had lower levels of total cholesterol LDL-cholesterol fraction, apolipoprotein A-1, but higher HDL-cholesterol compared to Anacetrapib their relatives.
