Organisational Effectiveness In Selected Grass Roots Sport Clubs In Western Australia, Elissa J. Burton

Theses: Doctorates and Masters

Grass roots sport clubs are the foundation for sport in Australia, they cater for mass participation across all ages and are predominantly managed by volunteers. The benefits of being involved in sport and in particular a sport club, both from a health and social capital perspective are well documented (Houlihan & Green, 2006; Hoye & Nicholson, 2008; Stewart, Nicholson, Smith, & Westerbeek, 2004). Australian governments at every level, provide funding for sport to support these benefits and often directly to sport clubs. Yet there is little published research on what makes a grass roots sport club effective (Koski, 1995), particularly …

Self-Determination Theory In Motivation To Adopt Physical Activity In Older Adults: A Community Based Approach, Alastair Stewart

Recovery From Supraspinal Fatigue Is Slowed In Old Adults After Fatiguing Maximal Isometric Contractions, Sandra K. Hunter, Gabrielle Todd, Jane E. Butler, Simon C. Gandevia, Janet L. Taylor

Exercise Science Faculty Research and Publications

This study compared the contribution of supraspinal fatigue to muscle fatigue in old and young adults. Transcranial magnetic stimulation (TMS) of motor cortex was used to assess voluntary activation during maximal voluntary contractions (MVCs) of elbow flexor muscles in 17 young adults (25.5 ± 3.6 yr; mean ± SD) and 7 old adults (73.0 ± 3.3 yr). Subjects performed a fatigue task involving six sustained MVCs (22-s duration, separated by 10 s). Young adults exhibited greater reductions in maximal voluntary torque (67 ± 15% of baseline) than the old (37 ± 6%; P < 0.001). Increments in torque (superimposed twitch) generated by TMS during sustained MVCs increased for the young and old(P < 0.001) but were larger for the old adults at the start of the sustained contractions and during recovery (P < 0.05). Voluntary activation was less for the old adults at the start of some sustained contractions and during recovery(P = 0.02). Motor-evoked potential …

Contributions Of Body Fat And Effort In The 5k Run: Age And Body Weight Handicap, Anne R. Crecelius, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

The 5K handicap (5KH), designed to eliminate the body weight (BW) and age biases inherent in the 5K run time (RT), yields an adjusted RT (RTadj) that can be compared between runners of different BW and age. As hypothesized in a validation study, however, not all BW bias may be removed, because of the influences of body fatness (BF) and effort (run speed; essentially the inverse as measured by rating of perceived exertion (RPE)). This study's purpose was to determine the effects of BF and RPE on BW bias in the 5KH. For 99 male runners in a regional 5K …

The Effects Of A Season-Long Relaxation Program On Anxiety And Performance In Female High School Track & Field Throwers, Jeremy Walker

Use of a single-subject research design was used to allow ongoing monitoring of each athlete’s anxiety levels and performance. Results indicated that 2 of the 3 participants had improved performance and reduced trait anxiety over the course of the season. Additional results indicated that there was no significant difference in performance between participants and non-participants and that the …

Occupational Relevance And Body Mass Bias In Military Physical Fitness Tests, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

Recent evidence makes a compelling case that U.S. Army, Navy, and Air Force health-related physical fitness tests penalize larger, not just fatter, service members. As a result, they tend to receive lower scores than their lighter counterparts, the magnitude of which can be explained by biological scaling laws. Larger personnel, on the other hand, tend to be better performers of work-related fitness tasks such as load carriage, heavy lifting and materiel handling. This has been explained by empirical evidence that lean body mass and lean body mass to dead mass ratio (dead mass = fat mass and external load to …

Time To Task Failure And Muscle Activation Vary With Load Type For A Submaximal Fatiguing Contraction With The Lower Leg, Sandra K. Hunter, Tejin Yoon, Joseph Farinella, Erin E. Griffith, Alexander V. Ng

Exercise Science Faculty Research and Publications

The purpose was to compare the time to failure and muscle activation patterns for a sustained isometric submaximal contraction with the dorsiflexor muscles when the foot was restrained to a force transducer (force task) compared with supporting an equivalent inertial load and unrestrained (position task). Fifteen men and women (mean ± SD; 21.1 ± 1.4 yr) performed the force and position tasks at 20% maximal voluntary contraction force until task failure. Maximal voluntary contraction force performed before the force and position tasks was similar (333 ± 71 vs. 334 ± 65 N), but the time to task failure was briefer …
