Sex Differences In The Effects Of Cortisol On Muscle Characteristics: A Meta-Analysis, Natalie Bitetti

CMC Senior Theses

Background: Cortisol plays a central role in both muscle breakdown and growth. These effects are highly dependent on dose and interactions with other hormones. It is known that men and women show considerable differences in their muscle structure and physiology, which are largely driven by hormonal differences. Cortisol release patterns may also vary between the sexes, with current research showing considerable disagreement. The interplay between cortisol and muscle, two highly variable and sexually dimorphic factors, may prove to have different effects in males versus females.

Objective: This meta-analysis integrates existing research on sex differences in cortisol-muscle physiology with existing research …

The Bradley-Terry Model In Binary Outcome Driven Rankings: An Apllication In Amateur Hockey, Connor Meissner, Jeremy M. Losak

Sport Management - All Scholarship

Ranking systems serve critical roles in sport settings, most notably in determining playoff participants and seeding. Numerous ranking methodologies exist that incorporate many input measures and produce models that are highly predictive of game outcomes. However, there are circumstances—especially for amateur sport leagues—in which more complex inputs are either unavailable or not desirable, as they may lead to adverse performance incentives. Therefore, the goal of this paper is to highlight a ranking methodology that only considers binary game outcomes, i.e., wins and losses. Specifically, we consider the efficacy of the Bradley-Terry Model to rank sport teams for playoff consideration. We …

Chronic Training Load And Dorsiflexion Range Of Motion Throughout A Season In Professional American Soccer, Tristan L. Young

Electronic Theses and Dissertations

Soccer has an incredibly complex movement profile. Players experience various types of strains on their body from the requirement to land in awkward positions while maintaining the ability to quickly accelerate and decelerate. Dorsiflexion range of motion (DFROM) is of concern due to the movement profile and ball control that requires constant eccentric and concentric actions at the talocrural joint. With an American soccer season spanning across nine months these demands can contribute to overuse, which has been linked to restricted range of motion. Restricted DFROM and asymmetries have been identified as injury predictors, but their relationship to performance has …

Minimal dose strategies, which generally reduce weekly exercise volumes to less than recommended guidelines, might improve muscle strength with minimal time investment. However, minimal dose strategies and their effects on muscle strength are still unclear. Here our aims are to define and characterize minimal dose resistance exercise strategies and summarize their effects on muscle strength in individuals who are not currently engaged in resistance exercise. The minimal dose strategies overviewed were: “Weekend Warrior,” single-set resistance exercise, resistance exercise “snacking,” practicing the strength test, …

In Vivo Human Medial Gastrocnemius Fascicle Behaviour And Belly Gear During Submaximal Eccentric Contractions Are Not Affected By Concentric Fatiguing Exercise, Matheus Daros Pinto, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2022 to 2026

Changes in muscle geometry and belly gearing during eccentric contractions influence fibre strain and susceptibility to muscle damage. They are modulated by the interaction between connective tissues and intracellular-intrafascicular fluid pressures and external pressures from neighbouring structures. Fatiguing exercise triggers fluid shifts (muscle swelling) and muscle activation changes that may influence these modulators. Our purpose was to measure medial gastrocnemius (MG) geometric changes in vivo during eccentric contractions before and after maximal concentric muscle work to test the hypothesis that fatigue would reduce fascicle rotation and muscle gear and provoke greater fascicle strain. Submaximal eccentric plantar flexor contractions at 40% …
