Force Doesn't Figure Into Fatigue

Force Doesn't Figure Into Fatigue Depending on whether you're right or left handed, one of your arms is probably stronger than the other. Same goes with your legs. A study published in the Journal of Science and Medicine in Sport suggests your dominant leg the one you favor when kicking a ball puts out about 4.6% more force than the other leg. But that doesn't mean the weaker leg fatigues more easily.

Researchers tracked right and left leg endurance while 18 young men in their early 20s performed leg presses at 20% of maximal force. Although force fluctuations increased with repetitions, and the dominant leg showed a larger decrease in force production during recovery, there were no differences in leg fatigue at any point during the exercise.

True Strength Moment: One way to bring up a weak point is to isolate the muscle group for exercise with heavier weight, more reps or both. Evening out a non-dominant limb's weakness can help you round out overall athletic performance in your sport.
