Recovery Perceptions And Techniques Of Ultramarathon Runners, Denise Howard

Doctorate in Kinesiology

Ultramarathons have become increasingly popular over the last few decades. Ultramarathons are run on various terrains in different climates and are extremely distressing physiologically and psychologically. Recovery is crucial to restore physiological and psychological functioning yet is underappreciated. Compared to other sports, research related to ultra-endurance is limited, and a gap in research exists on effective recovery modalities and duration for ultrarunners. This study aimed to examine ultrarunners' practice and perceptions regarding recovery techniques and duration. An electronic survey designed for this study collected participants' perceptions about recovery and included physiological and psychological recovery factors. A total of 159 ultrarunners …

Nutrient Supplementation For Pre- And Post Acl Operation & Rehabilitation In Female Basketball Players, Mackenzie Steele, Joshua Munoz

Department of Nutrition Student Projects

Understanding how nutrition and dietary protocols can help female athletes in the process of “returning to sport” after an anterior cruciate ligament (ACL) repair surgery should be discussed amongst interprofessional post-operational care teams. Amongst athletes, female counterparts experience ACL injuries at a higher incidence rate than males, this is due to a variety of biological factors while returning to sport at a lower rate. Due to this, it is important to analyze and evaluate the data available from sports journals on the effects diet and supplements may have on the musculoskeletal system. ACL grafts are often taken from a donating …

The Impact Of Sleep On Athletic Performance: A Review Of The Literature, Rylan J. Pratt

Honors Thesis

This paper reviewed the literature regarding sleep and athletic performance, specifically identifying the problem of sleep debt in student athletes, the effects of sleep debt, and what factors negatively influence sleep, along with how to improve sleep. The literature revealed that it is common for athletes to not get adequate sleep. Sleep debt can have psychomotor and physiological effects on the body, which decreases optimal athletic performance. The many factors that negatively impact sleep include high intensity training sessions, travel, sleep disturbances, caffeine and/or alcohol consumption, and pre-competition anxiety. Recommendations for athletes that are struggling to achieve adequate sleep include, …

Perceptions Of Ncaa Division I Baseball Pitchers On Treatment Modalities For Pitching Arm Health, Thomas Williams

Graduate Theses

Throwing athletes of all sports have similarities, even if the sport itself is very different. Throwing an object creates a great amount of stress on the body, particularly at the shoulder and the elbow. A baseball pitcher should train and compete in all three planes of movement-sagittal, frontal and transverse. Training for throwing athletes has two main goals: to increase throwing power and to reduce throwing injuries. Analyzing training habits of a throwing athlete includes an understanding of the modalities they perform in order to prevent potential injuries from occurring. Baseball pitchers are extremely susceptible to throwing injuries, and must …

Caffeine Intake Helps Maintain 3-Km Cycling Performance The Morning Following Sleep Restriction, Erin E. Horil

Masters Theses, 2010-2019

Abstract

Introduction: Although a full understanding of the role of sleep is debated, it is widely accepted that sleep is important for recovery from heavy exercise. Recent research suggests that sleep restriction (SR) may negatively impact recovery and subsequent performance. It is unknown if caffeine supplementation mitigates this performance decrement. Our objective was to investigate the effect of caffeine supplementation on exercise performance following one night of SR in trained cyclists.

Methods: Subjects (n=10) completed a 3-km time trial (TT) and an exhaustive bout of exercise in the evening (EX1), then returned to repeat the TT the following …
