Mechanisms Affecting Post-Activation Potentiation Following Voluntary Isokinetic Knee Extension, Laurent B. Seitz

Theses: Doctorates and Masters

The present research was designed to: 1) determine whether the voluntary PAP effects commonly observed after conditioning activity (CA; i.e. muscular contraction prior to a ‘test’ contraction) are a consequence of acute neuromuscular alterations relating to the CA itself, or whether they simply reflect warm-up and/or familiarisation effects; 2) clarify the influence of the contraction velocity, duration and total work characteristics of the CA on voluntary PAP; 3) determine the factors allowing stronger individuals to express higher level of voluntary PAP; and 4) determine the peripheral and central mechanisms of voluntary PAP in human skeletal muscle. In Study 1, the …

Pain Assessment And Possible Mechanism Of Delayed Onset Muscle Soreness, Wing Yin Lau

Theses: Doctorates and Masters

Muscle pain is felt during exercise or daily activities for several days after performing unaccustomed exercise, which is referred to as delayed onset muscle soreness (DOMS). Many people experience DOMS, but its underlying mechanisms are not fully understood. One of the challenges in the investigation of DOMS is its subjective nature, which makes the assessment ambiguous, thus establishing a standardised protocol is necessary. The present thesis scrutinised muscle pain assessments (Study 1, Study 2), developed a new assessment of muscle pain focusing on muscle fascia (Study 3), and investigated why DOMS is reduced after the second than the first bout …

A Series Of Studies Examining The Development Of Sprint Speed And Momentum Of International Rugby Union Players, Matthew John Barr

Theses: Doctorates and Masters

Sprinting speed is a highly valued physical ability in rugby. There is little research examining sprinting biomechanics in rugby players and it is unclear the extent that sprinting speed and sprint momentum can even be improved in highly trained rugby players and how different speed and strength training methods might help improve it. This thesis consists of 6 studies that examine the sprinting biomechanics of elite rugby players, how strength and power training might improve sprinting speed and the potential for elite rugby players to make further improvement in their sprinting speed and sprint momentum.

Key biomechanical factors were that …

Concussions: Education For Coaches And Safe Return To Play For Athletes, Catherine Fettkether

Honors Program Theses

Head injuries can occur due to a variety of reasons, including falls, auto accidents, and contact sports. In 2010 the Center for Disease Control reported that 2.5 million traumatic brain injuries occurred in the United States. Any injury the body sustains requires that a person take the appropriate steps to have the most successful outcome. Appropriate action with an injury is not just limited to recovery, but being aware of the potential injury and acting accordingly. This is even more important when the injury is sustained by the brain. A situation in which brain injuries are becoming a larger issue …

Comparison Of Static And Countermovement Jump Variables In Relation To Estimated Training Load And Subjective Measures Of Fatigue, Matthew Sams, Satoshi Mizuguchi, Brad Deweese, Kimi Sato

Matthew L Sams

The purpose of this study was to compare changes in static and countermovement jump variables across a competitive season of collegiate soccer to estimated training load and subjective measures of fatigue. Monitoring data from 21 male collegiate soccer players were retrospectively examined. Nine vertical jump sessions occurred across the season in addition to daily training load assessment and daily mood-state assessment. Group average changes from the first testing session were calculated and compared to the group average training load for the 7 days preceding each vertical jump testing session for static and countermovement jump height and allometrically scaled peak power. …
