The Impact Of Extrinsic Motivation On Athletic Performance, Timothy Petranchuk Jr.

Kinesiology, Sport Studies, and Physical Education Synthesis Projects

Youth participation in sports include recreational, organized, informal programs as well as Olympic hopefuls. These young athletes can have positive or negative experiences from their participation in sports. Perhaps an important aspect of what makes those experiences either positive or negative is how they are motivated to participate in these activities. Motivation in these young athletes can come in various ways. One main theme found in the literature that has a direct influence on their experiences is extrinsic motivation. It is important to understand how these athletes' performances are affected by outside influences, such as parents, coaches and peers. This ...

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko Jun 2019

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko

Electronic Theses, Projects, and Dissertations

Aging in skeletal muscle is characterized by a loss in muscular performance. This is in part related to the direct loss of muscle mass due to senescence, known as sarcopenia. With age, skeletal muscles lose force production, contractile speed, and power production. The force velocity relationship of muscle is a product of force production and contraction speed, both of which decline with age; however, the mechanisms and trajectory of this decline are not well understood. Exercise has positive effects on muscle, and thus may assist in maintaining performance in old age. However, few long-term studies have been performed to examine ...

Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng Jan 2019

Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng

Theses and Dissertations--Kinesiology and Health Promotion

Submaximal exercise performance is, in part, limited by the accumulation of metabolic byproducts and energy system capacities. Curcumin and the combination of curcumin and fenugreek soluble fiber (CurQfen®) have been shown to increase endogenous antioxidants and metabolic byproduct clearance as well as reduce inflammation and lipid peroxidation, and therefore, may enhance submaximal aerobic thresholds. In addition, there is evidence that the galactomannan component of fenugreek, used to enhance bioavailability of curcumin, may also have potential physiological effects related to the up regulation of free fatty acid oxidation Therefore, the purpose of this study was to examine the effects of curcumin ...

Special Environments: Altitude And Heat, Philo U. Saunders, Laura A. Garvican-Lewis, Robert F. Chapman, Julien D. Périard

Faculty of Health Sciences Publications

High-level athletes are always looking at ways to maximize training adaptations for competition performance, and using altered environmental conditions to achieve this outcome has become increasingly popular by elite athletes. Furthermore, a series of potential nutrition and hydration interventions may also optimize the adaptation to altered environments. Altitude training was first used to prepare for competition at altitude, and it still is today; however, more often now, elite athletes embark on a series of altitude training camps to try to improve sea-level performance. Similarly, the use of heat acclimation/acclimatization to optimize performance in hot/humid environmental conditions is a ...

Offspring Dispersal Ability Covaries With Nest-Site Choice, David M. Delaney, Fredric J. Janzen

Ecology, Evolution and Organismal Biology Publications

Optimal maternal investment is often a tradeoff between conflicting pressures and varies depending upon environmental context and intrinsic female traits. Yet, offspring phenotype might also interact with such factors to influence investment. In aquatic turtles, terrestrial nests constructed farther from shore often have higher survival because nest predators tend to forage along environmental edges. However, offspring from eggs deposited farther inland must migrate farther to water upon emergence. We released hatchling common snapping turtles (Chelydra serpentina) at varying distances from a drift fence and monitored survival during overland dispersal. Survival decreased with dispersal distance and no selection on body size ...

Biomechanical Analysis Of Jumping: The Influence Of External Load And Countermovement Depth On Deceleration Strategies And Performance, Leland Adam Barker May 2018

Biomechanical Analysis Of Jumping: The Influence Of External Load And Countermovement Depth On Deceleration Strategies And Performance, Leland Adam Barker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jumping performance has traditionally been measured by jump height alone. In recent years, the reactive strength index (RSI = Jump height / jump time)) has been used as another measure of jump performance. According to RSI, which was developed to assess eccentric force production, jump performance can improve by increasing jump height, decreasing jump time, or both simultaneously. However, it is not clear how force production correlates to RSI variables. If RSI is meant to be a practical measure of eccentric force production, it should correlate strongly to eccentric and amortization force production during jumping. Thus, the purpose of the first study ...
