‘Use it or lose it’. A common phrase emanating from the world of health and fitness, is not only a cliché. It holds actual clinical significance when it comes to the musculoskeletal and cardiovascular systems.

Muscle Usage

Muscle is comprised of hundreds of thousands of muscle fibres made up of contractile proteins that are encased in a big stocking-like sleeve. When we exercise muscle, we damage these muscle fibres with the body responding by producing more contractile proteins, thereby increasing fibre size and muscle mass. So we go to the gym 3 times per week, our muscle mass increases and we look good for the beach. But what happens if we undergo a period of an inactive, sedentary lifestyle?

 

Muscle Inactivity

Muscle fibres are divided into two groups; slow twitch, are the postural muscles that are always working at very low levels to maintain posture and look after joints; fast twitch are the bigger, stronger muscles that give us movement. Research has shown that the slow twitch postural muscles are the first fibres to atrophy (get smaller) in the presence of inactivity, and this can occur in as little as 3 days! With an ever growing industry of technology, we may find ourselves bound to our PC for 8 or more hours a day. It is in this situation that muscles especially around the abdominal and gluteal regions, will atrophy and be replaced with a layer of subcutaneous fatty tissue. This loss of postural muscle mass increases the likelihood of suffering low back, hip, pelvis or tendon overload injuries.

Effects of Muscle inactivity

A period of physical inactivity has many deleterious effects on the cardiovascular system. Long term inactivity increases the risk of cardiovascular diseases including coronary heart disease, and diabetes. The American heart association recommends at least 30 minutes of moderate level exercise at 65% maximum heart rate, 3-4 times per week in order to maintain cardiovascular health, aerobic fitness and stay trim. Inactivity is defined as anything that falls short of 3 sessions per week, for less than 20 minutes. A common cardiovascular response to aerobic training is an increase in the size and strength of the left side of the heart muscle, which increases the capability of the cardiovascular system to supply the body tissue with oxygen and nutrient rich blood. With a short period of inactivity, this increase in heart strength can reverse rapidly, with a concomitant reduction in cardiac output and aerobic capacity. If the period of inactivity lengthens, the risk of CV disease increases. In collaboration with inactivity, factors such as diet, genetics and lifestyle factors play a significant role in the manifestation of these CV diseases.


It seems maintaining an active lifestyle allows us to preserve muscle mass in order to protect our joints against injury, while acting as our first line of defence against cardiovascular disease. Not to mention it maintains a healthy body image. With the pending holiday season fast approaching, it is crucial to sustain a modified level of exercise, as it is much easier to retain muscle mass and aerobic capacity, as opposed to starting from scratch after 4 weeks of laziness!
