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 …

The purpose of the study was to compare the physiological responses of skeletal muscle to a resistance training (RT) program using repetition maximum (RM) or relative intensity (RISR). Fifteen well-trained males underwent RT 3 d·wk−1 for 10 weeks in either an RM group (n = 8) or RISR group (n = 7). The RM group achieved a relative maximum each day, while the RISR group trained based on percentages. The RM group exercised until muscular failure on each exercise, while the RISR group did not reach muscular failure throughout the intervention. Percutaneous needle biopsies of the vastus lateralis were obtained …


The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke Jun 2019

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

Michael W. Ramsey

Daily undulating periodization (DUP), using daily alterations in repetitions, has been advocated as a superior method of resistance training, while traditional forms of programming for periodization (Block) have been questioned. Nineteen Division I track and field athletes were assigned to either a 10-week Block or DUP training group. Year and event were controlled. Over the course of the study, there were four testing sessions, which were used to evaluate a variety of strength characteristics, including maximum isometric strength, rate of force development, and one repetition maximum (1RM). Although, performance trends favored the Block group for strength and rate of force …

The Correlation Between Strength Levels Measured Through Dynamic Strength Exercises And The Incidence And Severity Of Injury Among Collegiate Athletes, Alex Jardine

Electronic Theses and Dissertations

Injury to athletes in sport occurs as a result of extrinsic and intrinsic risk factors. Mounting evidence points toward decreased strength as a predictor of injury in athletes. By comparing strength levels in functional movement patterns to injury, the strength and conditioning professional will be able to design effective training programs to reduce the incidence of injury in sport better. The purpose of this study was to determine the correlation between strength measured through dynamic strength exercises (power clean, the squat, and the bench press) among collegiate athletes and the incidence and severity of injury. We hypothesized that greater incidence …

Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams Jan 2012

Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams

Electronic Theses and Dissertations

Phosphatidic Acid (PA) is a natural phospholipid compound derived from lecithin which is commonly found in egg yolk, grains, fish, soybeans, peanuts and yeast. It has been suggested that PA is involved in several intracellular processes associated with muscle hypertrophy. Specifically, PA has been reported to activate protein synthesis through the mammalian target of rapamycin (mTOR) signaling pathway and thereby may enhance the anabolic effects of resistance training. To our knowledge, no one has examined the effect of PA supplementation in humans while undergoing a progressive resistance training program. To examine the effect of PA supplementation on lean soft tissue …
