How Exercise Affects The Musculoskeletal System In The Biological Sexes: A Literature Review, Lauren Connolly

Honors Program Theses

Exercise has countless benefits for the human body. Physical activity increases overall health and reduces the risk of developing many chronic diseases. While the entire body is impacted by exercise, the musculoskeletal system is perhaps targeted most directly. Muscle contraction is required to complete any form of exercise, which helps build muscle mass and consequently strengthens bones. The physiology of musculoskeletal growth after exercise is the same for all individuals. However, the magnitude of this growth is not the same for men and women. Men have a profound ability to gain muscle mass that most women are not capable of …

Recoverability Of Large Vs Small Muscle Groups, Jacob Alan Clark

Dissertations and Theses @ UNI

The purpose of this study was to assess differences in recovery between muscles with larger cross-sectional area (Quadriceps) compared to muscles with smaller cross-sectional area (Biceps). Recreationally trained male weight lifters aged 18-30 (n = 9) volunteered in this muscle recovery study. All participants were asked to attend two testing sessions in addition to an initial meeting, all of which took no more than 45-mintues per session to complete. After this initial session where the 10 RM in the biceps curl and quadricep extension were determined, participants were scheduled to perform the biceps curl and quad extension for four sets …

The Acute Effects Of Multiple Resisted Sled-Pull Loads On Subsequent Sprint-Running Performances, Carl Stephen Crouse

Dissertations and Theses @ UNI

Sled-pulling is a commonly implemented form of training for various sports. However, few studies have used sled-pulling as a means of acutely enhancing sprintrunning performances. The purpose of this study was to investigate how various sledpulling resistance loads (95% and 110% of body mass) effect subsequent, unloaded, sprint-running performances, possibly with aid from the effect known as Post-Activation Potentiation (PAP). PAP is a physiological phenomenon which increases the rate of force development of skeletal muscle which may result in the enhancement of power (speed-strength) dominant activities such as sprint-running and jumping.

Participants were a mix of males (n = 11; …

Gender Differences In Social Support During Injury Rehabilitation, Chelsey Ann Bruns

Dissertations and Theses @ UNI

Athletic injury can be a stress-inducing event that could have negative consequences on the psychological health of the athlete (Anderson & Williams, 1988; Gould, Udry, Bridges, & Beck, 1997). Injuries not only challenge the athlete physically, but also mentally challenge their ability to cope and overcome. A growing amount of research has indicated social support as a key factor in the rehabilitation process for an injured athlete (Yang, Peek, Lowe, Heiden, & Foster, 2010). Athletic injury causes an emotional disruption, and social support could influence the athlete’s reaction to the injury and his or her ability to cope with rehabilitation …

Development And Psychometric Evaluation Of A Post Exercise Exhaustion Scale Utilising The Rasch Measurement Model, Mark D. Hecimovich, Jeremiah J. Peiffer, Allen G. Harbaugh

Faculty Publications

Objectives: The objective of this study to report on the development and psychometric analysis of a scale to measure post exercise exhaustion.

Design: This study utilised the Rasch measurement model for the psychometric analysis of a new scale aimed at measuring acute onset exhaustion in athletes.

Method: An extensive literature review, feedback from athletes and an expert panel from educators in psychology, sports science and exercise physiology provided feedback on the scale, providing evidence of content validity. A final survey, consisting of the 25 items and completed by three hundred and seventynine athletes (Sport: 187 tri-athletes and 192 cyclists; gender: …

Anaerobic Power Of A College Basketball Team Throughout One Season, Mark Frederick Ackerman

Dissertations and Theses @ UNI

The purpose of this study was to describe the changes in anaerobic power of a NCAA Division I men's college basketball team over the course of a season using the Wingate Anaerobic Test.

Administered on a bicycle ergometer, the Wingate Anaerobic Test was given to 15 members of the University of Northern Iowa men's basketball team four different times over the course of a season. During the season the team participated in no specific conditioning program for anaerobic power and relied on regular practices and games for all conditioning.

The Wingate Anaerobic Test measured maximal anaerobic power, anaerobic capacity, and …
