Perceived Exertion And The Increase In Risk Of Injury In Rotc Cadets, Courtney D. Chiaramonte

Theses, Dissertations and Capstones

Context: Musculoskeletal injury in military personnel creates problems due to economic losses, and decreased training. The repetitive motions associated with military training and the daily physical training sessions can lead to the development of fatigue. Fatigue has been shown to contribute to 18% - 26% of musculoskeletal injuries. [7] Several studies have explored fatigue as a risk of injury during occupation. Fatigue has been shown to increase the perceived effort during physical exercise. The purpose of this study was to characterize the perception of effort during physical training sessions and injury rates in ROTC cadets throughout an academic year.

Impact Of One Night Sleep Restriction On Autonomic Function And Heart Rate Variability In Recreational Cyclists, Amanda J. Becker

Senior Honors Projects, 2010-2019

Introduction: Sleep quality has been shown to influence autonomic function. The autonomic nervous system (ANS) responds to stressors by regulating key functions such as heart rate. Autonomic function can be monitored via heart rate variability (HRV). Athletes are prone to poor sleep quality due to psychological and physical stresses of training and competing. Our objective was to investigate the function of the ANS at rest and during exercise following a night of normal sleep (SLP+) and a night of restricted sleep (SLP-).

Methods: Subjects (n=9) completed a familiarization trial and two identical experimental trials under different sleep conditions: SLP- (3-hour …

Using Maximum Power As A Variable For 1rm Prediction In The Squat And Bench Press, Sean O'Connor

Electronic Theses and Dissertations

Many Strength and Conditioning (S&C) coaches utilize a one-rep max (1RM) exercise test to gauge the maximal strength of athletes, and then prescribe resistance training programs based on a relative percentage of 1RM to obtain strength or power adaptations. However, many S&C coaches have raised questions regarding the safety and necessity of a 1RM test. Attempts to mitigate the weaknesses of 1RM testing have led to other methods of testing including repetition max testing (3RM, 5RM, 10RM, etc.) as well as load/velocity profiling. The main purpose of this study is to determine if 1RM can be accurately estimated from maximal …
