Muscles generate lactic acid as a by-product of intensive exercise and, as this builds up, the pH of the blood around the muscles drops. This drop in pH eventually prevents the muscles contracting further. At this point, you need to rest to allow the lactic acid to be metabolised.

What is the role of biological body factors in physical activity?

Effects of biological, including genetic/genomic and environmental factors, with many interactive effects, will determine individual differences in the functioning of these physiological systems and hence the level of physical of physical activity.

What is physical exercise in biology?

How does working out relate to biology?

Exercise represents a major challenge to whole-body homeostasis provoking widespread perturbations in numerous cells, tissues, and organs that are caused by or are a response to the increased metabolic activity of contracting skeletal muscles.

What systems are used during exercise?

Three metabolic pathways generate the energy required to perform an exercise: the phosphagen pathway, the glycolytic pathway, and the oxidative pathway, together known as the energy systems.

How do the cardiovascular and respiratory systems work together during exercise?

The cardio-respiratory system works together to get oxygen to the working muscles and remove carbon dioxide from the body. During exercise the muscles need more oxygen in order to contract and they produce more carbon dioxide as a waste product.
