The Coaches’ Eye: Exploring Coach Decision-Making During Talent Identification, Alexandra Hannah Roberts

Theses: Doctorates and Masters

For decades, researchers and practitioners interested in talent identification have discussed the coaches’ eye: the elusive ability that allows some coaches to ‘see’ qualities in an athlete that point to their talent or future potential. While there is significant anecdotal evidence of coaches who possess this ability, there is little empirical research supporting the validity or reliability of the coaches’ eye. Guided by ecological dynamics, this thesis employs mixed methodologies to explore the decision-making that underpins how high-level coaches identify talent in Olympic combat sports. These four studies captured the processes of thirty- four coaches during the talent identification process, …

Development, Assessment And Application Of A Novel Algorithm To Automatically Detect Change Of Direction Movement And Quantify Its Associated Mechanical Load In Elite Australian Football, Aaron Balloch

Theses: Doctorates and Masters

The ability to change direction rapidly and efficiently is critical to team-sport performance, including Australian football (AF), where a player’s capacity to rapidly decelerate, move laterally and re-accelerate is critical when evading opponents, tackling, or reacting to the unpredictable bounce of the ball or movement of another player. The biomechanical loading requirements of change of direction (COD) movement are angle and velocity dependant. Cumulative COD movement can impart high levels of neuromuscular and metabolic fatigue which can adversely affect the efficiency of subsequent movement efforts. Despite widespread use of microtechnology devices (the vast majority containing a global navigation satellite system …

Improving Sprint Performance In Road Cycling: The Forward Standing Sprint Position, Paul Franciscus Johannes Merkes

Theses: Doctorates and Masters

The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies outlined in this thesis was to manipulate CdA, physiology, …

Analysis Of Perceptual-Motor Calibration Processes In Indoor Climbing, Andrew Stephen Walsh

Theses: Doctorates and Masters

This research programme examines how people perceive maximal reach-and grasp-ness in climbing, and as such these questions will be limited to climbing.

Is experienced gained from performing daily submaximal reaching sufficient for the accurate perception of maximal horizontal reaching affordances in rock climbing?

How is perception of maximal horizontal boundary of reach-and grasp-ness affected by: hold size, body position, additional load, or fatigue.

How will inducing fatigue affect how a participant calibrates distance and their movement economy?

The Application Of Maximal Mean And Critical Speed And Metabolic Powers For The Quantification Of External Load In Soccer, Cameron Nicholas Lord

Theses: Doctorates and Masters

In Association football, often referred to as “soccer”, competitive match play is typically known to represent the greatest physical demand that players experience. The demands associated with match running performance may impact training outcomes and injury risk. As a result, practitioners evaluate these demands to ensure that performance is optimised. To assist in this process, global positioning systems (GPS) are typically used to quantify displacement variables and, more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to …

The Mechanics Of Front Leg Loading During Cricket Fast Bowling: Delivery Variations, Spell Demands, And The Effects Of Strength Training, Samuel J. Callaghan

Theses: Doctorates and Masters

The goal of fast bowling in cricket is to dismiss a batsman for as few runs as possible. To assist this goal, fast bowlers will attempt to maximise ball release velocity (BRV) to decrease the decision-making and stroke execution time of the opposing batsmen. Fast bowlers will also employ various delivery lengths (i.e. short, good and full) to assist in affecting a batsman’s stroke execution.

Several issues remain to be addressed with regards to the biomechanical assessment of fast bowling. This is particularly evident when analysing fast bowling performance (i.e. BRV), the implications of front foot loading (i.e. vertical and …

A Profile Of Game Style, Physical, Technical And Tactical Skills, And The Pathways That Underpin Expertise In Australian Youth Soccer Players, Bradley Scott Keller

Theses: Doctorates and Masters

The attainment of expertise has been the focus of research in many domains including music, chess and sport. This research has progressed with many theories detailing the best way to develop expertise and nurture talent in sport. Soccer is a multifaceted sport which requires a number of physical, technical and tactical skills to be successful, making it difficult to achieve expertise. Although Australia’s performance on the international stage is improving, there is a lack of evidence to inform the most effective development pathways to support the next wave of talented youth soccer players. Therefore, the aim of the thesis was …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …

An Investigation Into The Creation Of Goal Scoring Opportunities In Women’S International Football; And A Comparison To Men’S International Football, Mark Scanlan

Theses: Doctorates and Masters

Football is the most popular sport in the world, played in over two hundred countries and it is governed by the Fédération Internationale de Football Association (FIFA), who host a World Cup every four year for both men and women. Women’s football is growing in terms of popularity, with this growth in popularity, research into the women’s game has begun to emerge. However, to date there is very little published research in women’s football that describes effective attacking strategies and the creation of goal scoring opportunities (GSO). Video of each match (52) from the Women’s World Cup (Canada 2015) was …

The Relationship Between Physical Exercise And Cognition In Children With Typical Development And Neurodevelopmental Disorders, Beron Wei Zhong Tan

Theses: Doctorates and Masters

This research project sought to investigate the relationship between physical exercise and cognition in children with and without a neurodevelopmental condition. To achieve this aim, three approaches were undertaken to explore the exercise and cognition relationship. The first approach sought to understand the efficacy of exercise interventions on cognition in individuals with a neurodevelopmental disorder. The second approach was to understand the effectiveness of an exercise activity when compared to a cognitively-engaging tablet game activity on measures of implicit learning and attention in children with and without a neurodevelopmental condition. The third approach was to investigate if psychophysiological measures could …

Accuracy In The Badminton Short Serve: A Methodological And Kinematic Study, Shayne Marc Vial

Theses: Doctorates and Masters

In sports, accuracy is an essential component of actions such passing, shooting, and aiming. Executing a movement or action that requires a high degree of accuracy is a critical determinant of success in many individual and team sports. Each sport has different methods for evaluating accuracy, however an overarching goal is to determine whether an object hits its target, or assess the distance by which it misses. However, in some sports accuracy is not readily measureable because an object might not reach a target, i.e. the object is intercepted, or it collides with another object or a person, or an …

The Development Of An Objective Multi-Dimensional Approach To Talent Identification In Junior Australian Football, Carl T C Woods

Theses: Doctorates and Masters

Talent identification (TID) is a pertinent component of the sports science discipline given the considerable influence it may have within the pursuit of excellence. Thus, research has attempted to identify the determinants of a talented performance through the use of objective testing procedures. However, many of these ‘traditional’ approaches have been operationalised by mono-dimensional objective physical performance tests that do not inherently account for the multi-dimensional requisites of game-play, particularly within a team sporting context. This is problematic when attempting to identify talent, as a successful performance in team sports is often the combination of physical, technical and tactical elements. …

An Investigation Of Technique And Equipment Factors Associated With Clubhead Speed In Golf, Christopher Joyce

Theses: Doctorates and Masters

If golfers achieve long hitting distances whilst maintaining their accuracy they will gain a competitive advantage. To increase hitting distance, faster clubhead speed is required and this can potentially be achieved through a number of factors. Firstly, anthropometric factors such as height and physical factors such as trunk rotational power have been previously considered to be of importance. However, biomechanical factors such as; the X-factor (separation of the trunk-pelvis alignment when viewed in the transverse plane), have been a major focus of recent research. Further, the interaction of the golfer with the implement they hit with i.e. the golf club …
