Improving muscular strength and endurance
MASCULAR strength and endurance is most evident in overload exercise programs as its principle indicates the process through which the demands placed on the body or in any of its system is intensified and increased.
The overload principle in other words improves muscular strength, muscular endurance, flexibility, and cardio-respiratory endurance if one exercises and performs in a period of time against the workloads that are above those normally encountered.
In the process, there are several ways that one can increase his exercise workload by increased load, increased exercise work rate, increased exercise work time, decreased rest, or combinations. The best example of overload through increased load can be witnessed in weight training or progressive resistance training, where athletes’ exercises at a given weight with a specified performance target should be reached, and then weights are added to set a new target.
On the other hand, increased work rate is best exemplified in sports like track and field and swimming. Performers in this kind of sports usually are concerned about their speed and time, and where their goal is to work towards a specified target time. After achieving their target time athletes keep the distance constant but tries to complete the work in a shorter period of time, the result in increased work rate or intensity as an overload then makes the performer run or swim the same distance at a faster rate of speed.
In overload programs, increased work time
usually is the opposite of the former exercise regimen, where, the rate of the rate of work remains constant but the performer is active for a longer period of time, just as a bodybuilder for example carries the same rate of weight, but the number of repetitions is increased.
The same that overload can also be induced by reducing the amount of rest provided between a set of exercise where increased work demands are produced that bring about overload. A combination of the overload factors can greatly increase the demands of an activity by such manipulations of the program, however, great care must be given by a performer or coaches and trainers so as to ensure that the program remains with the individual capacity of a person.
