Molecular adaptations of lipolysis to physical activity

Molecular mechanisms of vascular adaptations to exercise. Physical activity as an effective antioxidant therapy?

A lack of exercise training and/or regular physical activity is a known risk factor for cardiovascular disease. Exercise training induces marked vascular remodeling by increasing angiogenesis and arteriogenesis. These changes in the architecture of the vascular tree are likely associated with functional changes and improved organ blood flow. Physical forces such as shear stress, transmural pres...

Cardiovascular adaptations to physical training.

The principal features of the cardiovascular responses to endurance training in normal subjects were well documented by the late 1960s (2, 23, 35, 84, 88) and are illustrated in Table 1. They include an increase in maximal oxygen uptake, stroke volume, and cardiac output with no change or a small decrease in maximal heart rate. Systemic vascular conductance increases and there is also an increa...

Molecular adaptations to concurrent training.

This study investigated the chronic effects of concurrent training (CT) on morphological and molecular adaptations. 37 men (age=23.7±5.5 year) were divided into 4 groups: interval (IT), strength (ST) and concurrent (CT) training and a control group (C) and underwent 8 weeks of training. Maximum strength (1RM) and muscle cross-sectional area (CSA) were evaluated before and after training. Muscle...

Cardiovascular adaptations to prolonged physical effort.

Molecular epidemiology of physical activity and cancer.

As in other areas of epidemiology, researchers studying physical activity and cancer have begun to include laboratory analyses of biological specimens in their studies. The incorporation of these "biomarkers" into epidemiology has been termed molecular epidemiology and is an approach primarily developed to study chemical carcinogens. Thus far, there has been no discussion in the field on how th...

Dietary and physical activity adaptations to alternate day modified fasting: implications for optimal weight loss

BACKGROUND Alternate day modified fasting (ADMF) is an effective strategy for weight loss in obese adults. OBJECTIVE The objective of this study was to examine the dietary and physical activity adaptations that occur during short-term ADMF, and to determine how these modulations affect rate of weight loss. METHODS Sixteen obese subjects (12 women/4 men) completed a 10-week trial consisting ...
