Sex Differences In Skeletal Muscle Fiber Types: A Meta-Analysis, James L. Nuzzo
Sex Differences In Skeletal Muscle Fiber Types: A Meta-Analysis, James L. Nuzzo
Research outputs 2022 to 2026
Biopsies have been acquired from living men and women to determine proportions of Type I (slow-twitch) and II (fast-twitch) skeletal muscle fibers since the 1970s. Sex differences have been assumed but the literature has not been submitted to meta-analysis. Here, the aim was to generate effect sizes of sex differences in muscle fiber cross-sectional areas, distribution percentages, and area percentages. Data from 2875 men and 2452 women, who participated in 110 studies, were analyzed. Myofibrillar adenosine triphosphatase histochemistry was used in 71.8% of studies to classify fibers as Type I, II, IIA, and/or IIX; immunohistochemistry, immunofluorescence, or sodium dodecyl sulfate-polyacrylamide …

Increasing muscle strength and cross-sectional area is of crucial importance to improve or maintain physical function in musculoskeletal rehabilitation and sports performance. Decreases in muscular performance are experienced in phases of reduced physical activity or immobilization. These decrements highlight the need for alternative, easily accessible training regimens for a sedentary population to improve rehabilitation and injury prevention routines. Commonly, muscle hypertrophy and strength increases are associated with resistance training, typically performed in a training facility. Mechanical tension, which is usually induced with resistance machines and devices, is known to be an important factor that stimulates the underlying signaling pathways to …
Pre-Season Body Composition Has Minimal Influence On In-Season Match Availability, And Match Performance In Female Australian Football League (Aflw) Players, Callum J. Mccaskie, Marc Sim, Robert U. Newton, Jarryd Heasman, Brent Rogalski, Nicolas H. Hart
Pre-Season Body Composition Has Minimal Influence On In-Season Match Availability, And Match Performance In Female Australian Football League (Aflw) Players, Callum J. Mccaskie, Marc Sim, Robert U. Newton, Jarryd Heasman, Brent Rogalski, Nicolas H. Hart
Research outputs 2022 to 2026
This study examined the relationship between pre-season body composition, in-season match performance, and match availability in female players competing in the Australian Football League Women's (AFLW) competition. With the outlawing of body composition assessments as part of pre-draft player evaluations in the AFLW, this study seeks to examine whether this is justified. Twenty-two (n = 22) players had body composition assessed with dual-energy x-ray absorptiometry at the beginning of the 2021 AFLW pre-season (whole-body and regional fat mass and lean soft-tissue mass [LSTM]). In-season match availability and match performance data (Coaches Score [CS], Champion Data Player Rank, average disposals, disposal …
