Furthermore, this is by gradually improving their capacity to resist forces, for instance, by using certain weight-lifting machines, free weights, and an individual’s body weight. It is aimed at imposing a gradually bigger resistance that fuels muscles strength development to meet the additional demand. During the endurance and strength training processes, the adaptive responses of the human skeletal muscles are differently affected as they undergo several physiological and metabolic changes in response to the activities.
Physical training initiates several spontaneous changes within the active muscles. The degree of the changes is often dependent on the nature of the exercise, for instance, the time consumed and the intensity of the training involved. The skeletal muscle, on the other hand, is a specialized tissue actively involved in the production of the tension force required in moving the skeletal system. The tension force in the tissue is produced due to the interactions between the actin and myosin.
