Depth Jumping: A Comparison Of The Most Effective Depth Jumping Techniques In The Improvement Of Power/Vertical Jumping, Stefan Darvishi Jul 2001

Depth Jumping: A Comparison Of The Most Effective Depth Jumping Techniques In The Improvement Of Power/Vertical Jumping, Stefan Darvishi

Graduate Theses

A four week depth jump training program was conducted to determine if there is a significant difference between bounce drop Jump technique and counter drop jump technique in improving leg power as measured by vertical jumping height. Eleven college females, age 18 to 21, involved in the sport of volleyball and basketball served as subjects in this investigation. Following pre-testing, the subjects were assigned to one of two treatment groups based on the sports they played. Both groups participated in the training two sessions per week. There were no control groups used in this investigation. The subjects in group one …

Isokinetic Dynamometer Versus A Multi-Axial Stability Platform In The Proprioception And Strength Training Of The Peroneal Muscle Group, Eric Johnson Jan 2001

Isokinetic Dynamometer Versus A Multi-Axial Stability Platform In The Proprioception And Strength Training Of The Peroneal Muscle Group, Eric Johnson

Theses, Dissertations and Capstones

Ankle injuries are the most common and frequent occurring injuries in sports today (Feuerbach, Grabiner & Koh, 1994). Ankle sprains usually occur in athletes that are participating in running or jumping activities. Injuries to the ankle joint represent about 20% of all sports related injuries, and 15% of all time lost injuries (Payne, Berg, & Latin, 1997). The majority of the sprains to the ankle occur to the lateral ligamentous structures due to the forcefully plantar flexion and inversion of the talocrural joint. This inversion mechanism accounts for 85% of all ankle sprains (Kinzey, Ingersoll, & Knight, 1997). Often after …

The Ability Of Cryotherapy To Effect Vertical Jump And Single-Legged Hop Test, Douglas W. Branch Jan 2001

The Ability Of Cryotherapy To Effect Vertical Jump And Single-Legged Hop Test, Douglas W. Branch

Theses, Dissertations and Capstones

Cryotherapy is an important component in the management and rehabilitation of musculoskeletal injuries that occur due to sports participation. Cryotherapy is described as the "therapeutic application of any substance to the body which results in the withdrawal of heat from the body" (Tsang, 1997). This cold modality is used initially when caring for injuries that are acute or chronic. The main reason for using cryotherapy in acute injury management is to lower the temperature of the injured tissue, which reduces the metabolic rate and helps the tissue to survive the period of hypoxia following an injury (Merrick, 1993). The effects …

The Effect Of Cycling On Muscle Activation In The Running Leg Of An Olympic Distance Triathlon, Tamika Heiden Jan 2001

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 Jan 2001

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 Jan 2001

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 Effect Of Prescribed And Preferred Intensity Exercise On The Relationship Between Self-Efficacy And Perceived Exertion In Older Adults, Keith R. Scotson Jan 2001

The Effect Of Prescribed And Preferred Intensity Exercise On The Relationship Between Self-Efficacy And Perceived Exertion In Older Adults, Keith R. Scotson

Theses: Doctorates and Masters

This study was concerned with acute responses to exercise in people over the age of 50 (N = 80). In particular the relationship between Self-efficacy and perceived exertion during exercise at workloads (a) based on a target heart rate (prescribed intensities) and (b) based on participant preference (preferred intensities) were observed. Perceptual (perceived exertion), Self-efficacy and heart rate responses of low active older participants engaged in either walking or cycle ergometer exercise at preferred and prescribed intensities were also reported. Significant inverse correlations were observed between pre and post exercise Self-efficacy and perceived exertion during acute exercise at prescribed intensities …

The Specificity And Sensitivity Of The Criteria Used To Measure Vo2max, Geoffrey D. Juranovich Jan 2001

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 …
