Document Summary
Muscular strength can be considered a foundation of physical development and wellbeing. What is strength: strength the ability for muscles to contact to produce a high force or torque (force. What is the purpose of determining maximal contraction capabilities: establish load for exercise prescription & monitor progression, monitor injury risk, rank clients strength according to norms. Prescription & progression: establish load for exercise prescription, quality training programs will always consider loading parameters is relation to a subjects maximum potential, facilitation of overload, ensures training specificity, minimise overreach.

Hamstrings (hs) act synergistically with acl via co-contraction. Standard process of strength assessment: maintain proper technique, consistent movement speed and depth, use of a spotter/s, equipment familiarisation, proper warm-up.
