The Influence Of Strength And Power Training On The Performance Of U.S. Marines, Kristopher J. Klein

Master of Science in Kinesiology

U.S. Marine Infantry conducts a job that requires strength, speed, and endurance; however military fitness training relies mainly on the endurance aspect. With numerous studies showing the correlation between an endurance mainstay within military organizations, and musculoskeletal and joint overuse injuries, this study seeks to understand the performance value in training the anaerobic energy systems. Specifically, we aim to determine whether strength and power training may be more beneficial to the tactical athlete than traditional training. Over a period of 12 weeks, 150 members of the U.S. Marine Infantry will participate in training five days a week with three days …

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone

Graduate Theses, Dissertations, and Problem Reports

The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed. To …

Differences In Lower Limb Kinetics In College Age Female Gymnasts To Coaches’ Perceived Efficiency In A Specific Counter Movement Jump Technique, Stephen Christopher Avgerinos

Theses and Dissertations

This thesis reports the results of a quantitative research project which examined kinetics of female collegiate gymnasts aged 18 to 21 performing a ‘punching’ counter-movement jump (CMJ) technique that is taught and required for exemplar scoring during NCAA competition. Twelve female gymnasts were recruited from the competitive team at Illinois State University. Participation was voluntary and athletes were not compensated. Each gymnast performed 8 punch-CMJ trials without coaching instruction except to perform a punching CMJ. The method of performing this CMJ began by stepping off from a 33 cm elevation, ‘punching’ off the force plates, and finishing with a landing …

Practical Applications Of Biomechanical Principles In Resistance Training: Neuromuscular Factors And Relationships, Jason Lake, Paul A. Swinton, Justin Keogh

Justin Keogh

This paper is the second in our three part series examining how a variety of biomechanical principles and concepts have direct relevance to the prescription of resistance training for the general and athletic populations as well as for musculoskeletal injury rehabilitation. In this paper, we considered different neuromuscular characteristics of resistance exercise. We started by defining the causes of motion, discussing force and Newton’s second law of linear motion. This led to discussion of impulse, and how its relationship with momentum can be used to study force-time curves recorded from different ground-based resistance exercises. This enables the sports biomechanist to …

Effects Of An In-Season Resistance Training Program On Lower Extremity Power Output In Collegiate Basketball Players, Kevin Lee King

Graduate Theses and Dissertations

The purpose of this study was to evaluate changes in muscle power performance in a horizontal (forward movement), vertical, and lateral directions in collegiate basketball players due to the presence of an in-season resistance training program (ISRTP). Four basketball teams were recruited for this study. Two women's basketball teams and two men's basketball teams participated with one team in each gender participating in an ISRTP and one team not participating in an ISRTP. Fifty-three collegiate basketball players (Females= 29, Males= 24) were successfully recruited for this project. Subjects were assessed for lower extremity muscle power and muscle strength at pre-season, …

Neuromuscular Function Following Lengthening Contractions, Geoffrey A. Power

Electronic Thesis and Dissertation Repository

Unaccustomed lengthening contractions have been shown to impair muscle function - however little is known regarding this impairment on muscle power - specifically, the velocity component of power during voluntary contractions in humans. The four studies presented in my thesis investigated power-loss following lengthening contractions in healthy young and old women and young men.

The purpose of Study 1 was to determine reliability of velocity-dependent power of the dorsiflexors using the isotonic mode of the Biodex Dynamometer. I determined the isotonic mode is reliable and can be used to track changes in velocity and power following fatigue and lengthening contractions. …

Aerobic Respiratory Costs Of Swimming In The Negatively Buoyant Brief Squid Lolliguncula Brevis, Ian K. Bartol, Roger Mann, Mark R. Patterson

Biological Sciences Faculty Publications

Because of the inherent inefficiency of jet propulsion, squid are considered to be at a competitive disadvantage compared with fishes, which generally depend on forms of undulatory/oscillatory locomotion. Some squid, such as the brief squid Lolliguncula brevis, swim at low speeds in shallow-water complex environments, relying heavily on fin activity. Consequently, their swimming costs may be lower than those of the faster, more pelagic squid studied previously and competitive with those of ecologically relevant fishes. To examine aerobic respiratory swimming Costs, O₂ consumption rates were measured for L. brevis of various sizes (2-9 cm. dorsal mantle length, DML) …
