Molecular Mechanisms Underlying The Contralateral Repeated Bout Effect (Crbe) In Human Skeletal Muscle, Ling Xin
Doctoral Dissertations
Eccentric (muscle lengthening) exercise induces temporary muscle damage that can lead to long-term muscle adaptation, a process known as the repeated bout effect where subsequent exercise results in less damage. The existence of a contralateral repeated bout effect (CRBE) has been controversial. The primary goals of this study were to: 1) validate the existence of the CRBE; and 2) define the underlying molecular mechanisms. Thirty-six young men performed 100 maximal eccentric actions of the knee extensors using one leg (bout 1) and repeated the exercise with the contralateral leg five weeks later (bout 2). Vastus lateralis muscle biopsies were …
Psycho-Physiological Effects Of Television Viewing During Exercise, Brian Carl Rider
Psycho-Physiological Effects Of Television Viewing During Exercise, Brian Carl Rider
Doctoral Dissertations
Purpose: To examine the effects of television (TV) viewing on psychological and physiological variables during a moderate-intensity exercise bout. Methods: 28 insufficiently active adults participated in this study. Each participant performed three separate 30-minute walking bouts on a motorized treadmill. The bouts were separated by 48 hours and the majority of participants completed all bouts within three weeks. During each bout, participants watched a program they selected (self-selected TV condition), a British Broadcasting Corporation (BBC) nature program the investigators selected (standardized TV condition), and one bout involved no TV viewing (no TV condition). Variables measured during exercise were: …
The Role Of The Extracellular Matrix In Mediating Muscle Soreness, Karen L. Riska
The Role Of The Extracellular Matrix In Mediating Muscle Soreness, Karen L. Riska
Doctoral Dissertations
The goal of this dissertation was to examine the role of the extracellular matrix (ECM) in muscle soreness. Study 1 examined how the disruption of the ECM from a minor surgery (e.g. muscle biopsy) affected muscle soreness. Study 1 showed that soreness levels increased at 24 h post-biopsy compared to baseline and resolved within 96 h. However, the level of muscle soreness at 24 h post-biopsy (20 mm) was lower than that reported for performing a strenuous and naïve exercise (40–80 mm). These results will help review boards at institutions where muscle biopsies are performed understand how a muscle biopsy …
