Youth sports programs: contribution to physical activity.

Adaptation to Submaximal Physical Training

Submaximal training can induce adaptational changes in the skeletal muscles, cardiovascular system, respiratory system, endocrine system, etc. Knowledge of the signs of adaptation and its magnitude, the factors causing it, as well as an awareness of the significance of the adaptation for the improvement of physical capacity to exercise is essential to develop an optimal training programme and w...

Oxygen free radicals and exercise: mechanisms of synthesis and adaptation to the physical training*

The interest about the mechanisms of generation and adaptation of oxygen free radicals (OFR) to exercise has increased significantly from the demonstration of its relation with the oxygen intake. The OFR are formed through the incomplete reduction of oxygen, generating species presenting high reactivity to other biomolecules, especially lipids and proteins of the cell membranes and even DNA. Th...

Mechanisms of Adaptation to Periodic Environmental Change

Despite Darwin’s pluralistic view that “natural selection has been the main, but not the exclusive means of modification” (Darwin, 1872) (quoted in (Lewontin and Gould, 1979)), subsequent major developments in evolutionary biology such as the theories of natural selection, the modern synthesis, and molecular neo-darwinism have biased scientific explanations of evolution towards gene-centric the...
