The Impact Of Dieting Culture Is Different Between Sexes In Endurance Athletes: A Cross-Sectional Analysis, Austin J. Graybeal, Andreas Kreutzer, Jada L. Willis, Robyn Braun-Trocchio, Kamiah Moss, Meena Shah

Faculty Publications

Background: Frequent dieting is common in athletes attempting to achieve a body composition perceived to improve performance. Excessive dieting may indicate disordered eating (DE) behaviors and can result in clinical eating disorders. However, the current nutrition patterns that underly dieting culture are underexplored in endurance athletes. Therefore, the purpose of this study was to identify the sex differences in nutrition patterns among a group of endurance athletes.

Methods: Two-hundred and thirty-one endurance athletes (females = 124) completed a questionnaire regarding their dieting patterns and associated variables.

Results: The majority of athletes did not follow a planned diet …

The Validity Of Using One Force Platform To Quantify Whole-Body Forces, Velocities, And Power During A Plyometric Push-Up, Zhanxin Sha, Boyi Dai

Faculty Publications

Background: Previous studies have typically measured velocity and power parameters during the push-up, either using one or two force platforms. The purpose of the study was to compare the force, velocity, and power parameters between the one-force-platform method and the two-force-platform method during plyometric push-ups.

Methods: Thirty-four physically active young adults participated in the study to perform the plyometric push-up. For the two-force-platform calculation method, the forces applied to the feet and hands were both measured. For the one-force-platform calculation method, the forces applied to the feet were assumed to be constant, while the forces applied to hands …

Differential Gene Expression Of Foxo1, Id1, And Id3 Between Young And Older Men And Associations With Muscle Mass And Function, Thomas W. Buford, Matthew B. Cooke, Brian D. Shelmadine, Geoffrey M. Hudson, Liz L. Redd, Darryn S. Willoughby

Faculty Publications

Background and aims: Aging is associated with significant losses of skeletal muscle mass and function. Numerous biochemical molecules have been implicated in the development of these age-related changes, however evidence from human models is sparse. Assessment of transcript expression is useful as it requires minimal tissue and may potentially be used in clinical trials. This study aimed to compare mRNA expression of proteolytic genes in skeletal muscle of young (18–35 yrs) and older (55–75 yrs) men.

Methods: Muscle tissue was obtained from young (n=14, 21.35±01.03 yrs) and older (n=13, 63.85±1.83 yrs) men using percutaneous biopsy, and transcript expression was quantified …
