The Effects Of Caffeine On Jumping Performance And Maximal Strength In Female Collegiate Athletes, Benjamin Burke, Kyle Travis, Henry Lang, Jeremy Gentles, Kimitake Sato, Caleb Bazyler
Undergraduate Honors Theses
Introduction: Caffeine has long been used to enhance athletic performance. The research regarding caffeine’s effects on strength and power performance is lacking, especially in female athletes. Purpose: To analyze the acute effects of caffeine on jumping performance and maximal strength in female collegiate athletes. Methods: Eight female collegiate athletes performed two testing sessions separated by one week. Using a double-blind approach, athletes randomly received 6 mg/kg of body mass of caffeine (CAF) or a placebo (PLA). Following 60min of quiet sitting and a standardized warm-up, athletes were tested on measures of squat jump height (SJH) and peak power (SJPP), countermovement …

Testing Vert™ Accelerometer To Identify Validity And Reliability When Compared To Switch Mat, Tara Mcdonald
Undergraduate Honors Theses
This present study was intended to identify the reliability and validity of the Vert™ device when compared to a Switch mat. Vert is a wireless device intended to measure jump count and jump height through an application on a smartphone or tablet and the Switch mat provides jump height using wireless sensors. Jump height is an important factor in many sports such as volleyball and basketball and it is important to have devices that coaches and trainers can use for testing that they can rely on. If this device is found to be valid and reliable, coaches and trainers …
Relationship Between Lower Body Strength, Countermovement Jump Height, And Optimal Drop Jump Drop Height, Cameron V. Griggs
Relationship Between Lower Body Strength, Countermovement Jump Height, And Optimal Drop Jump Drop Height, Cameron V. Griggs
Electronic Theses and Dissertations
The purpose of this study was to understand the relationship between back squat one-repetition maximum relative to body mass (1RMrel), countermovement jump height (CMJH), and optimal drop height in drop jump (DHopt). Fifteen male participants with various sport backgrounds and training experience completed a one repetition maximum (1RM) back squat, maximum countermovement jump (CMJ), and drop jumps (DJ) from incrementally increasing drop heights to determine which drop height elicited the greatest jump height. The DHopt testing protocol was unique in that smaller increments were used to determine DHopt compared to what has been reported in literature previously. Pearson correlation coefficients …
