The Effect Of Cycling On Muscle Activation In The Running Leg Of An Olympic Distance Triathlon, Tamika Heiden
The Effect Of Cycling On Muscle Activation In The Running Leg Of An Olympic Distance Triathlon, Tamika Heiden
Theses : Honours
Anecdotal reports from triathletes highlight the transition from cycling to running as the most difficult due to the change from non-weight carrying cycling activity to weight hearing running activity. The aim of this study was to examine the effects of prior cycling on activation of lower limb muscles in running during an Olympic distance triathlon. Ten elite level triathletes underwent two conditions; a 40krn ride followed by a 2km run and a 10km run followed by a 2km run, at their Olympic distance race pace. Testing was carried out in the field with at least one week between tests. EMG …
Muscle Responses To High-Intensity Eccentric Exercise : A Comparison Between Untrained And Highly Resistance-Trained Subjects, Gregory T. Morgan
Muscle Responses To High-Intensity Eccentric Exercise : A Comparison Between Untrained And Highly Resistance-Trained Subjects, Gregory T. Morgan
Theses : Honours
Eccentric exercise, which is when the muscle produces force as it lengthens, has been shown to result in decrements to muscle functions. This study was designed to investigate whether there was a difference between the muscle responses of untrained (n = 8) and resistance-trained (n = 8) individuals after a bout of high-intensity eccentric exercise of the elbow flexors. All subjects were males aged 18 to 45 years and recruited based on specific training criteria. Subjects performed l0 sets of 6 maximal eccentric contractions of the elbow flexor muscles on an isokinetic dynamometer. 10 seconds rest was provided between each …
Back Stress And Assistance Exercises In Extreme Weightlifting, Adam J. Beard
Back Stress And Assistance Exercises In Extreme Weightlifting, Adam J. Beard
Theses : Honours
The purpose or this study was to test the suitability or selected assistance exercises to strengthen the low back for the Olympic lilts in elite weightlifters. Four subjects were filmed by a five-camera Motion Analysis system operating at 120Hz. The subjects completed both or the Olympic lifts (Snatch and Clean) at a near one repetition maximum and four assistance exercises (Bent-over Row, Clean Pull Deadlift, Romanian Deadlift, and Good Morning) at an intensity typically performed at a routine training session. Peak moments, compressive and shear forces about the L5/S1 intervertebral joint were calculated via a top-down inverse dynamics model. Comparisons …
The Specificity And Sensitivity Of The Criteria Used To Measure Vo2max, Geoffrey D. Juranovich
The Specificity And Sensitivity Of The Criteria Used To Measure Vo2max, Geoffrey D. Juranovich
Theses : Honours
The use of V02MAX as a measure of cardiorespiratory fitness is widespread throughout the fields of exercise physiology, physiology and medicine. VO2MAX is described as the maximal rate of oxygen consumption during increasing exercise intensities and is defined by a plateau or levelling off of oxygen consumption (VO2). Taylor et al. (1955) derived the primary criterion for a levelling off (plateau) of VO2 at the end of an incremental exercise test to exhaustion to be a change in VO2 (ΔVO2) /kg/min during the final minute. This primary criterion has been widely accepted …
