Thermoregulatory And Exercise Performance : Responses To Cooling With Ice Slurry Ingestion, Rodney Siegel
Thermoregulatory And Exercise Performance : Responses To Cooling With Ice Slurry Ingestion, Rodney Siegel
Theses: Doctorates and Masters
The rise in body core, skin and muscle temperatures associated with exercise
in hot environments (~30°C and above) is known to impair performance over a
variety of exercise modes and durations. Precooling has become a popular strategy to
combat this impairment, as evidence has shown it to be an effective method for
lowering pre-exercise core temperature, increasing heat storage capacity and
improving exercise performance in the heat. To date, the majority of precooling
manoeuvres are achieved via external means, such as cold water immersion and the
application of cooling garments; methods which have been criticised for their lack of
practicality …

Long-Term Training Adaptations In Elite Male Volleyball Players, Jeremy Sheppard, Robert Newton
Long-Term Training Adaptations In Elite Male Volleyball Players, Jeremy Sheppard, Robert Newton
Research outputs 2011
Abstract: Sheppard, JM, and Newton, RU. Long-term training adaptations in elite male volleyball players. J Strength Cond Res 26(8): 2180–2184, 2012—Several investigations have demonstrated differences in anthropometry, jump performance, and strength variables between developmental and elite-level volleyball players. However, within the elite level of play, the magnitude of change that can occur with training is unclear. The purpose of this investigation was to examine the anthropometric, vertical jump, and strength quality changes over 2 years in a group of national team volleyball players. Fourteen national team volleyball players (age, 23.0 ± 4.1 years; height, 1.98 ± 0.07 m; weight, 91.7 …

Relationships Between Triathlon Performance And Pacing Strategy During The Run In An International Competition, Yann Le Meur, Tierry Bernard, Sylvain Dorel, Chris Abbiss, Gerard Honnorat, Jeanick Brisswalter, Christophe Hausswirth
Research outputs 2011
PURPOSE: The purpose of the present study was to examine relationships between athlete's pacing strategies and running performance during an international triathlon competition. METHODS: Running split times for each of the 107 finishers of the 2009 European Triathlon Championships (42 females and 65 males) were determined with the use of a digital synchronized video analysis system. Five cameras were placed at various positions of the running circuit (4 laps of 2.42 km). Running speed and an index of running speed variability (IRSVrace) were subsequently calculated over each section or running split. RESULTS: Mean running speed over the first 1272 m …
Influence Of Environmental Temperature On 40 Km Cycling Time-Trial Performance, Jeremiah J. Peiffer, Chris R. Abbiss
Influence Of Environmental Temperature On 40 Km Cycling Time-Trial Performance, Jeremiah J. Peiffer, Chris R. Abbiss
Research outputs 2011
The purpose of this study was to examine the effect of environmental temperature on variability in power output, self-selected pacing strategies, and performance during a prolonged cycling time trial. Nine trained male cyclists randomly completed four 40 km cycling time trials in an environmental chamber at 17°C, 22°C, 27°C, and 32°C (40% RH). During the time trials, heart rate, core body temperature, and power output were recorded. The variability in power output was assessed with the use of exposure variation analysis. Mean 40 km power output was significantly lower during 32°C (309 ± 35 W) compared with 17°C (329 ± …
Circadian Rhythms In Exercise Performance: Implications For Hormonal And Muscular Adaptation, Weipeng Teo, Michael Newton, Michael Mcguigan
Circadian Rhythms In Exercise Performance: Implications For Hormonal And Muscular Adaptation, Weipeng Teo, Michael Newton, Michael Mcguigan

Almost all physiological and biochemical processes within the human body follow a circadian rhythm (CR). In humans, the suprachiasmatic nucleus regulates sleep-wake cycle and other daily biorhythms in line with solar time. Due to such daily physiological fluctuations, several investigations on neuromuscular performance have reported a distinct CR during exercise. Generally, peak performances have been found to occur in the early evening, at approximately the peak of core body temperature. The increase in core body temperature has been found to increase energy metabolism, improve muscle compliance and facilitate actin-myosin crossbridging. In addition, steroidal hormones such as testosterone (T) and cortisol …
The Effect Of Cluster Loading On Force, Velocity, And Power During Ballistic Jump Squat Training, Keir Hansen, John Cronin, Michael Newton
The Effect Of Cluster Loading On Force, Velocity, And Power During Ballistic Jump Squat Training, Keir Hansen, John Cronin, Michael Newton
Research outputs 2011
Purpose: The purpose of this study was to investigate the effect of set structure, in terms of repetition work:rest ratios on force, velocity, and power during jump squat training. Methods: Twenty professional and semiprofessional rugby players performed training sessions comprising four sets of 6 repetitions of a jump squat using four different set configurations. The first involved a traditional configuration (TR) of 4 × 6 repetitions with 3 min of rest between sets, the second (C1) 4 × 6 × singles (1 repetition) with 12 s of rest between repetitions, the third (C2) 4 × 3 × doubles (2 repetitions) …

Taaffe, Prue Cormie, Nigel Spry, Susan K. Chambers, Carolyn Peddle-Mcintyre, Michael Baker, James Denham, David Joseph, Geoff Groom, Robert Newton
Research outputs 2011
Background: The presence of bone metastases has excluded participation of prostate cancer patients in exercise intervention studies to date and is also a relative contraindication to supervised exercise in the community setting because of concerns of fragility fracture. However, this group of patients often have developed significant muscle atrophy and functional impairments from prior and continuing androgen deprivation that is exacerbated by subsequent and more intensive interventions such as chemotherapy. The aim of this study is to determine the efficacy and safety of a modular multi-modal exercise program in prostate cancer patients with bone metastases. Methods/Design: Multi-site randomized controlled trial …
Effect Of Transcranial Direct Current Stimulation (Tdcs) On Maximal Voluntary Isometric Strength And Endurance Of The Elbow Flexors, Benjamin Kan
Theses: Doctorates and Masters
The present study investigated the effects of transcranial direct current stimulation (tDCS) on maximal voluntary contraction strength (MVC) and the time to failure (TTF) of an isometric muscle endurance test of the elbow flexors. Prior to the main study, the test-retest reliability of MVC and TTF measures was investigated using 10 men (33.2 ± 9.4 y) for the measurements separated by 60 min (within-day) and one week (between-day). Coefficient of variation (CV), Intraclass correlation (ICC, R), a paired t-test and the Bland-Altman plots revealed that TTF at 30% MVC task was reliable, and was able to detect a possible effect …
Feedback Control For Exergames, Jeff Sinclair
Feedback Control For Exergames, Jeff Sinclair
Theses: Doctorates and Masters
The concept of merging exercise equipment with video games, known as exergaming, has the potential to be one of the main tools used in addressing the current rising obesity epidemic. Existing research shows that exergaming can help improve fitness and additionally motivate people to become more active. The two key elements of attractiveness - how much people want to play or use the exergaming system; and effectiveness – how effective the exergaming system is in actually increasing or maintaining physical fitness, need to be maximised to obtain the best outcomes from an exergaming system; we put this forward as the …
The Influence Of Set-Repetition Configuration In Eccentric Exercise On Muscle Damage And Repeated Bout Effect, Roy Y.H. Chan
The Influence Of Set-Repetition Configuration In Eccentric Exercise On Muscle Damage And Repeated Bout Effect, Roy Y.H. Chan
Theses: Doctorates and Masters
It is well known that maximal eccentric exercise induces muscle damage, especially when it is performed for the first time. However, muscle damage is attenuated in subsequent bouts of the same or similar exercise, which is known as the repeated bout effect. One of the factors affecting the magnitude of muscle damage and the repeated bout effect is the number of eccentric contractions; however, it is unknown if different set-repetition configurations with the same number of eccentric contractions would result in different magnitudes of muscle damage and adaptation. This study investigated changes in muscle strength, range of motion (ROM), muscle …
