Physically fit people must keep their body in good shape. They must continuously workout to build muscular strength. Or, they will lose a significant amount of muscle.
Reason Physical Inactivity Affects Muscle Strength
According to a recent report issued by the Center for Healthy Aging and the Department of Biomedical Sciences at the University of Copenhagen, “New research reveals that it only takes two weeks of not using their legs for young people to lose a third of their muscular strength”. The research also stated that lack of exercise for at least two weeks, leaves their legs “par with a person who is 40-50 years their senior”. This can be especially alarming to people who become injured, decide to take a vacation, or those who take time off from being physically active. Furthermore, they can lose significant muscle mass, which has been shown to decrease their metabolism.
Research Study Results of How Physical Inactivity Affects Muscle Strength
In the Denmark study, a leg pad was used to monitor inactivity. Participants had one leg that was immobilized. Younger and older men were observed. According to the report, both subjects experienced muscle loss. However, the younger participates experienced a greater muscle loss than older study participants. Based on the results, older people lost approximately 25% muscle strength. Yet, younger individuals experienced a 33% decrease in muscular power. It should be noted that younger people tend have more muscle mass than older people, which results in a greater muscle loss. Also, physically fit people have a greater muscle mass than individuals who are unfit. So, if the physically fit person becomes ill and cannot workout, they will lose more muscle mass than the unfit individual, who is physically inactive.
Process to Muscle Strength after Physical Inactivity
Once you lose muscle strength due to physical inactivity, you must do more than bicycling. In the study, the participants biked 3 to 4 times per week for a total of six weeks. However, this did not increase the strength they had prior to physical inactivity. Weight training is essential to regaining muscle strength. In addition, it will take at least three times the amount of time for an inactive person to return to their original muscle strength.
