- Abstract
- PhD; "The complex and contrast methods are two separate, but related approaches to resistance training that present intriguing options for coaches who are seeking to enhance an athletes explosive lower body movement. This intrigue is caused by the post-activation potentiation (PAP) phenomenon, which provides the physiological underpinning for these training methods. Exploitation of the PAP response is believed to elicit acute responses, and ultimately chronic adaptations in an individuals explosive force producing ability to an extent that is greater than can be obtained through conventional training methods. However, evidence to support the use of these training methods is derived from investigations that have reported acute increases in performance within a single session and not over an extended period of time. Additionally, the complex method of training, in which sets of a heavy resistance exercise (conditioning action) are performed prior to sets of a lighter explosive exercise has not been investigated as extensively as the contrast method, in which heavy and light exercises are alternated in a set-by-set fashion, leading to question which method is more effective. Furthermore, it is currently not understood if a static or dynamic conditioning action is more effective in complex or contrast methods, and how a change in body position from seated to standing acutely effects explosive lower body movement. Therefore, four studies were designed to address these current gaps in the literature." "The first study sought to determine the reliability of the explosive force variables of jump height (JH), peak bar velocity (BV), peak force (PF), and peak power (PP) obtained from a countermovement jump (CMJ) test." "The second study of the thesis examined the acute responses to five different unconventional resistance training methods which attempted to capitalise on a PAP response and one conventional session where CMJs were performed without any influence from a previous conditioning action." "The third investigation of this thesis was a nine-week training study in which participants were randomly assigned to two training interventions, conventional (n = 11) or complex (n = 9)." "Due to the dramatic improvements observed in CMJ height, that were not observed in other variables, it was questioned whether the specific instructions provided to participants during training and testing throughout the study to jump for maximal height had any influence on these results. This question led to the design of a fourth study. Though not directly related to complex or contrast training, this investigation into the effects of instructions on CMJ variables has scope to alter the way this test is conducted both in research and in a practical setting.
