It is vital that mental well being is studied as much as physical health throughout the injury and rehabilitation process. This study reviewed previous literature on the social impacts of team sports, psychological and social implications of injury, the impact of residual pain, and finally the process of retirement. A survey was also conducted at a small liberal arts college in Southern California …

The Association Between Aerobic Exercise And Changes In Hdl Quality Induced By Egg Consumption – A Post-Hoc Analysis Of A Randomized, Controlled, Crossover Dietary Intervention Study, Rachael Woodruff, Catherine J. Andersen

Honors Scholar Theses

Abstract

Objective: Daily intake of whole eggs and aerobic exercise have independently been shown to increase high-density lipoprotein cholesterol (HDL-C) and measures of HDL function, suggesting cardioprotective effects of these lifestyle interventions. However, it is unknown whether exercise volume can synergistically or differentially impact diet responses and egg effects on HDL. Therefore, we evaluated whether exercise volume was associated with distinct effects of consuming different egg-based diets on measures of HDL size, function, and composition.

Methods: Twenty-six healthy men and women completed a 16-week randomized, controlled, crossover intervention study which aimed to investigate the effects of egg-free, egg-white, and whole-egg …

Cannabidiol (Cbd) And Resistance Training: Does Cbd Attenuate Acute Pain?, Guillermo Pacheco

Masters Theses & Specialist Projects

INTRODUCTION: Resistance training (RT) is an advantageous form of physical activity for health and performance benefits; these benefits are maximized when done strenuously. However, strenuous RT can induce acute inflammatory pain which can lead to delayed-onset muscle soreness (DOMS). Common analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) can block protein synthesis, so other alternatives are needed for exercise and athletic communities to maintain physiological adaptations. Cannabidiol (CBD) is a non-psychotropic cannabinoid with purported anti-inflammatory, anti-oxidative, and analgesic properties. One of the main reasons for the use of CBD in exercise is pain alleviation; however, research in humans is limited. Therefore, the …
