Time To Task Failure

This evidence explained that the greater muscle mass involved in stronger person makes them to adapt with the time to failure. Next, Matkowski, Place, Martin, and Lepers (2011) further a study in comparing the different of unilateral and bilateral exercise on time to task failure and associated maximal voluntary contraction force performed on knee extensor muscle. The researcher found there is a significant different on time to task failure where the bilateral exercise were shorter as compared to unilateral exercise. However, the maximal voluntary contraction force and maximal voluntary activation losses were greater after a unilateral exercise as compared after a bilateral exercise. The reason behind this is due to the differences in the activation pattern, in muscle perfusion and/or in the muscle mass involved. Matkowski et al. (2011) propose in their study that the time to task failure of the knee extensor muscle during submaximal fatigue contraction depends on the muscle mass involved. That mean the bigger and stronger the muscle the less fatigue it is. Other than that, the reason why bilateral exercise time to fatigue was shorter because of advance motor unit pool recruitment. The electrical stimulation of motor nerve allows detaining a possible modification in the process of excitation-contraction coupling. The one leg task have induced a greater time to task failure that resulting with greater contractile alterations and a higher maximal …show more content…
Unilateral exercise seems to be more beneficial in comparing with bilateral exercise. However, according to Fleck and Kraemer (2004), both training need to be use to allow the diversity effect to take place in a training program that being designed to facilitates athletes to have a variety of different stimuli after they begin to have an adaptation towards a training and progress to the next
