Muscles and Exercise

Exercise has several reasons and functions. People may exercise to improve their fitness, bone strength, recover from an injury or illness, to lose weight, improve cardiovascular health, sleep better, to compete in sporting events, or to make their muscles bigger (muscle hypertrophy). There are different types of exercise.

Aerobic exercise – sessions are of long duration with medium-to-low levels of exertion. The muscles are used well below their maximum strength capacity. A marathon is an example of an aerobic activity with very long duration.

Aerobic activities rely mainly on the oxygen (aerobic) system and use a higher proportion of the “slow twitch” (Type I) muscle fibers. Energy consumption comes from carbohydrates, fat and protein. Lots of oxygen is consumed and very little lactic acid is produced.

Anaerobic exercise – in this type of activity, the muscles contract intensely at much nearer their maximum strength. Athletes aiming for improved strength, speed and power will focus more on this type of exercise.

A single anaerobic activity lasts from a few seconds up to a maximum of two minutes. Anything that lasts longer will have a large aerobic metabolic component.

Examples include anaerobic exercise include: weight lifting, sprinting, climbing, and fast skipping (jumping rope).

Anaerobic exercises use “fast-twitch muscle fibers” (Type II muscles) much more. The main fuel sources are ATP or glucose; much less oxygen, fat and protein is used. This type of activity produces lots of lactic acids.

If you focus on anaerobic exercises you will get stronger, while anaerobic exercises will make you fitter. Many sports require a combination of fitness and strength, such as rugby, boxing, wrestling, or judo.

It is never too late to exercise – researchers at Martin-Luther-University of Halle, Germany, explained that exercise among elderly people considerably counteracts muscle breakdown that occurs during old age. They added that exercise for this age-group also increased strength and lowered inflammation caused by aging and heart failure. Dr. Stephan Gielen and team explained that heart failure patients had similar benefits to anybody else who exercises. Age should not be a barrier for regular exercise they stressed.
