The Psychology Of Motivation In Sport, Nicholas Salomone

Whittier Scholars Program

The purpose of this paper is to give a general overview of motivation theory in sport psychology. Beginning with self-confidence in sport, the basic models will be presented, showing how each built upon the last to create a more and more comprehensive and reliable structure for the measurement and evaluation of motivational style. From there, the models of causal attribution, which have evolved from Heider’s 1958 unidimensional structure to Weiner’s revised multidimensional models, will be covered. Nicholls’ (1984) goal perspective theory will then be discussed with emphasis on types of goal orientation and their positive and negative connotations. The self-determination …

Assessment Of Static Balance Ability In An Athletic Pediatric Population, Cailyn Rogers

Theses : Honours

There is a large amount of conjecture surrounding the reliability of methods of balance assessment and the outcome variables used to assess balance in pediatric populations. There has also been limited research conducted on the balance ability of an athletic pediatric population, and the factors which may affect that ability. The purpose of this research is firstly to determine the reliability of postural sway measures used to assess balance including: average displacement of the centre of pressure in the mediolateral and anterior-posterior directions relative to both the centre of the plate and the centre of the base of support; peak …

A Series Of Studies On Professional Rugby League Players, Daniel G. Baker

Theses: Doctorates and Masters

Rugby league football is a popular game in Australia, which appears to rely heavily upon strength, power, speed and endurance due to the nature of the phyiscal contacts. In an effort to discern the importance of upper body strength, power speed and endurance to rugby league players a retrospective data analysis was performed. Three areas of investigation were: 1) the testing of upper body physical qualities of strength, power, speed and strength-endurance and their significance to playing status in the elite national first-division (NRL), second-division (SRL) and third-division (CRL), 2) the effect of acute training variable manipulations upon power output …

Validation Of A 5k Age And Weight Run Handicap Model, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

Though increasing age and body weight (BW) have been widely known to be associated with slower distance run times, the common convention in 5K road races is to categorize competitors by age and, sometimes, BW. This has the disadvantage of assigning only small numbers of competitors to age categories and giving advantage to runners close to the minimum age or BW values allowable. Using recent advances in the modeling of distance run performance by BW combined with empirical evidence quantifying the independent effect of age on cardiovascular endurance, we previously published the derivation of the 5K Handicap (5KH), an age …
