Recovery Perceptions And Techniques Of Ultramarathon Runners, Denise Howard
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 …
Effects Of Branched-Chain Amino Acid Supplementation On Exercise Induced Muscle Damage And Delayed Onset Of Muscle Soreness After A Bout Of Eccentric Exercise, Crystal Lee
Electronic Thesis and Dissertation Repository
Branched-chain amino acids (BCAA) have the potential to reduce both exercise-induced muscle damage (EIMD) and delayed onset of muscle soreness (DOMS) after a bout of eccentric contractions (ECC). The purpose of this study was to determine the effects of BCAA supplementation for 12 days prior to and for an additional 7 days following a bout of ECC on EIMD and DOMS. Sixteen women with no prior experience with strength training were assigned randomly to a BCAA group or a placebo group. Only four participants completed the trial due to COVID-19 (another completed 72h of recovery and was included). Participants supplemented …
The Influence Of Set-Repetition Configuration In Eccentric Exercise On Muscle Damage And Repeated Bout Effect, Roy Y.H. Chan
The Influence Of Set-Repetition Configuration In Eccentric Exercise On Muscle Damage And Repeated Bout Effect, Roy Y.H. Chan
Theses: Doctorates and Masters
It is well known that maximal eccentric exercise induces muscle damage, especially when it is performed for the first time. However, muscle damage is attenuated in subsequent bouts of the same or similar exercise, which is known as the repeated bout effect. One of the factors affecting the magnitude of muscle damage and the repeated bout effect is the number of eccentric contractions; however, it is unknown if different set-repetition configurations with the same number of eccentric contractions would result in different magnitudes of muscle damage and adaptation. This study investigated changes in muscle strength, range of motion (ROM), muscle …
