Determining The Contributions Of The Intrapersonal Factors Of Personality Disposition, Ability, And Attitude To Precompetitive State Anxiety, Jacquelyn Rae Wright

Dissertations and Theses @ UNI

The purpose of this study was to determine the relative contributions of personality disposition (competitive A-trait), ability (skill level), and attitude (perceived ability, confidence, self-esteem) to state anxiety prior to competition. It was hypothesized that personality disposition (competitive A-trait) would be the strongest predictor of competitive state anxiety prior to competition.

Forty-two Luther College women basketball and softball players were selected for participation in the study. The Sport Competition Anxiety Test (SCAT) was used to assess A-trait. The Competitive State Anxiety Inventory-2 (CSAI-2) was used to assess three subcomponents of precompetitive state anxiety (cognitive anxiety, somatic anxiety and self-confidence). This …

The Effect Of Interval And Continuous Training On Maximal Oxygen Consumption And Performance On The 1.5 Mile Run Of College Age Males And Females, Deborah Lynn White

Dissertations and Theses @ UNI

Interval and continuous training and their effects on maximal oxygen consumption have been studied extensively. Virtually all of the studies reported in the literature have defined interval training as running a given distance at a maximal or near maximal intensity with intervening [sic] rest periods. This study defined interval training as running a given distance at a submaximal intensity of 85% of the maximum heart rate. The purpose of this study was to determine the effects of interval and continuous training on the maximal oxygen consumption, performance on a 1.5 mile run, and body composition of college age males and …

Validation Of A One-Mile Test As A Measure Of Maximum Oxygen Consumption For Males Aged 16-18 Years, Andrew John Myers

Dissertations and Theses @ UNI

Maximum oxygen consumption is considered to be the best indicator of the aerobic power of the cardiorespiratory system (Patton, Vogel, & Mello, 1982). The direct measure of maximum oxygen consumption requires a well-equipped laboratory, trained personnel, and a high degree of subject motivation and effort. These problems have led to attempts to develop indirect methods for estimating maximal oxygen consumption. The purpose of this study was to validate an indirect method for measuring maximum oxygen consumption. Specifically, the purpose was to validate a one-mile walk test as a measure of maximum oxygen consumption for males aged 16-18 years. Twenty-six male …

The Effect Of Pedal Frequency And Resistance On Oxygen Consumption During Bicycle Ergometer Work In College Females, Sue Joseph Joslyn

Dissertations and Theses @ UNI

Total workload on a bicycle ergometer is determined by the amount of resistance and the pedal frequency. Predicting oxygen consumption on a bicycle ergometer is currently based on total workload being performed, regardless of resistance and pedal frequency. The purpose of this study was to investigate the effects of pedal frequency and resistance on oxygen consumption at constant workloads during bicycle ergometer work in college-age females. It was hypothesized that changes in pedal frequency and resistance would cause significant differences in oxygen consumption at a constant workload.

Fourteen healthv, untrained females, age 19 to 22, performed maximal oxygen consumption tests …

A Comparison Of Oxygen Consumption In Light And Heavy Resistance Weight Training Methods In Males, Kean Gerard Richard

Dissertations and Theses @ UNI

Heavy resistance and low resistance weight training methods are commonly used in off season conditioning programs for various sports. Research has indicated that heavy resistance training elicits muscular strength development whereas low resistance training elicits the development of muscular endurance. However, there is very little or no research which has investigated a comparison of oxygen consumption between heavy resistance and low resistance training while keeping work constant.

The purpose of this investigation was to compare the oxygen cost of performing heavy and low resistance weight training methods. Also, a second purpose of the study was to determine the contribution of …

Effects Of A Supplementary Depth Jumping Program On Leg Strength, Leg Power, And Sprinting Speed In Sprinters And Jumpers, Christopher E. Bucknam

Dissertations and Theses @ UNI

Many sport activities require strength and power training programs to help athletes achieve optimal performances. These types of programs are aimed at developing strength and power only through the voluntary shortening of the muscle during contraction. Research has indicated, however, that the faster a muscle is forced to lengthen, or stretch before shortening the greater tension it will exert. Plyometric training, specifically depth jumping, is one technique that does emphasize a forced maximum stretch over a short period of time. The purpose of the study was to determine the effect of a plyometric conditioning program, when used in addition to …

Factors Which Contribute To Tumbling Height In College Gymnasts, Mark Douglas Ball

Dissertations and Theses @ UNI

Tumbling is one of the major components in a floor exercise routine. One of the basic tumbling sequences in a routine is a roundoff back handspring tuck back salto. This sequence is the building block for more difficult back tumbling such as the double back salto. By increasing the height of the back salto, more amplitude, aesthetic impression, and difficulty may possibly be performed. These improvements should lead to a higher score. This study was an analysis of a tuck back salto to determine those factors which contribute to tumbling height, and to establish their relative contribution to the action. …
