▼ The purpose of this research was to determine if two different conditioning loads could induce acute improvements in height and power output during counter-movement jumping. Ten recreationally active men who were currently resistance training the legs participated in the study. On two separate occasions, subjects completed either five repetitions of a light jump squat or five repetitions of a moderately heavy back squat. At 5- and 15-minutes following the conditioning loads, counter-movement jumps were completed and compared to determine if the different condition loads or the recovery time following the conditioning loads affected counter-movement jump performance. The peak and average height and power outputs of the counter-movement jumps were assessed using a motion analysis system and force plate. A significant improvement was found for the average counter-movement jump height following the jump squat conditioning load. A significant difference was also determined for average power output between 5- and 15-minutes following both conditioning loads. Lighter conditioning loads performed explosively may acutely improve aspects of counter-movement jumping following a 5-minute rest period. Advisors/Committee Members: Gilders, Roger M.

▼ The purpose of this study was to determine the difference in the glycemic response of high and low aerobic fitness men to glucose, and one novel slow and fast digestible carbohydrate (CHO). The glycemic index (GI) value of both novel CHO was determined for the high (n = 6) and low (n = 6) aerobic fitness men. Overall, GI values were 76.44±16.02 for the fast CHO and 48.96 ±17.30 for the slow CHO. Between the high and low fitness men the GI differed significantly, the fast CHO was found to be 86.71±16.15 and 66.17±7.12 and the slow CHO was found to be 59.13±8.50 and 38.79±18.38, for the low and high fitness men respectively. The glycemic response was significantly different among the trials (glucose, fast and slow CHO, p = .0001). The GI of the novel CHO (fast and slow CHO)depended upon the aerobic fitness level of healthy young men. Advisors/Committee Members: Kushnick, Michael R.

▼ This research paper provides a comparison between the metabolic cost and contact forces between treadmill (TM) and mini-trampoline (MT) exercises. Thirteen (22.5 years -/+ 2.18) subjects (7 males and 6 females) performed exercises at either a set pace (126 pace per minute) or a set heart rate (65% - 85% heart rate reserve (HRR) -/+ 10bpm) on the TM or the MT both with and without hand and ankle weights (3.6 kg). For the metabolic cost comparison, each subject participated in 8 randomly ordered exercise sessions (TM or MT, with or without weights, at a set pace or heart rate range). Each exercise session lasted for 10 minutes, during which heart rates (HR) were recorded and the expired gases were collected to analyze the caloric expenditure and METS. Twelve (22.75 -/+ 2.13) subjects (7 males and 5 females) performed 4 randomly ordered trials, for the contact forces; during each an 8 second sample window was collected on the TM and MT with and without weights at a set pace (126 pace per minute). Subjects used the same pair of shoes for each trial with shoe insoles imbedded with sensory cells to collect the contact forces (Newtons) for both feet. For METS, caloric expenditure, and heart rate at an absolute load (126 pace per minute), there was a significantly (p
