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 …

Powerlifting Participation And Engagement Across All Ages: A Retrospective, Longitudinal, Population Analysis With Comparison To Community Strength Norms, Daniel J. Van Den Hoek, Alistair Mallard, Joel M. Garrett, Patrick L. Beaumont, Robert J. Howells, Jemima G. Spathis, Joshua Pearson, Christopher Latella

Research outputs 2022 to 2026

Background: In Australia, one-third of people ≥ 15 years perform regular resistance training and 90% of those do not meet current health guidelines. All age groups should engage in regular resistance exercise, to maintain strength and function. Objectives: To identify trends in powerlifting competition participation in Australia by sex and age group from 1968 to 2022, and to compare the strength of powerlifting competitors to population age- and sex-based normative values. Method: The number of unique participants and total competition entries for each year were analysed using Australian powerlifting competition data. Subdomains of age and sex were investigated, and mean …
