[Truncated abstract] Anterior cruciate ligament injuries are a major problem in sport. The purpose of this thesis was to investigate the causative factors of ACL injuries and to study the effect of various types of lower-limb training on underlying neuromuscular mechanisms involved in stabilisation and risk of ACL injury. Investigation of the mechanisms was conducted on controlled balance and strength tests as well as in sporting manoeuvres. It was aimed to assess if the neuromuscular changes map over into the performance of sporting manoeuvres and if potential for loading on the ACL and risk of injury was reduced or exacerbated . . . ACL strain can be decreased through reduction in the applied loads and greater knee flexion. Further to this, muscle activation has the ability to reduce loading on the ACL through co-contraction and selective activation patterns. This thesis demonstrated differing neuromuscular adaptations from various training types that map over into the performance of sporting manoeuvres. The research indicated that the Balance-Training was the most favourable in reducing potential for injury risk on the ACL. Alternatively strength training elicited neuromuscular changes that were likely to increase the risk of force on the ACL. The Machine+Balance training resulted in some negative and positive outcomes with the balance training tending to counteract the negative affects of machine weights training resulting in small improvements in muscular support and load reduction. This study provides us with better understanding of the underlying mechanisms from various training types and their potential affect on risk of ACL injury.
