The Study Of A Generalized Fitness Education Program's Effect On Personality Traits, Garrett Schliep 2023 University of Nebraska at Omaha

The Study Of A Generalized Fitness Education Program's Effect On Personality Traits, Garrett Schliep

Theses/Capstones/Creative Projects

This longitudinal study was to measure the influence of a generalized fitness education program on the percentile of individuals’ personality traits in college aged individuals. The personality traits are those determined in the Five Factor Model of Personality. The Five Factor Model of Personality is a beneficial tool used in exercise psychology that refers to a broad domain of personality traits often referred to as the “Big Five”. The findings reject the hypothesis that a fitness education program would shift an individual’s personality a statistically significant amount.

A Comparison Of Muscle Recruitment Across Three Straight-Legged, Hinge-Pattern Resistance Training Exercises, Jeremy R. Dicus, Samuel H. Ellestad, Jesse E. Sheaffer, Carol A. Weber, Noah C. Novak, Michael E. Holmstrup

International Journal of Exercise Science

International Journal of Exercise Science 16(4): 12-22, 2023. Hinge exercises are critical to building a balanced resistance training program in concert with ‘knee-dominant’ (e.g., squat, lunge) exercises. Biomechanical differences between various straight-legged hinge (SLH) exercises may alter muscle activation. For example, a Romanian deadlift (RDL) is a closed-chain SLH, while a reverse hyperextension (RH) is open-chain. Likewise, the RDL offers resistance via gravity while the cable pull-through (CP) offers redirected-resistance through a pulley. A deeper understanding of the potential impact of these biomechanical differences between these exercises may improve their application to specific goals. Participants completed repetition-maximum (RM) testing on …
