The purpose of the study was to determine whether an 8-week strength and power resistance training program would elicit an increase in club head speed (CHS). In addition to measuring CHS, this study aimed to determine if there were increases in muscular strength and power as a result of the 8-week program. Procedures: The participants for this study consisted of 6 male and 6 female NCAA division II collegiate golfers, age ranging from 18-23 years. All participants were experienced golfers and were not competing in a school supported golf season at the time of the study. The participants were separated by gender, then randomly assigned to either the intervention (N=6) or control group (N=6). Pre-test measures were taken to measure CHS, vertical jump height, back squat 1 RM, deadlift 1 RM, and clean 1 RM. The average and peak swing velocities from 3 max effort swings were recorded and analyzed. The participants then proceed to undergo an 8-week resistance training program. The experimental group performed a strength and power resistance training intervention designed to elicit muscular strength and power. The control group performed their normal off-season resistance training program. The participants trained three days a week. The intervention and control group were then tested post-treatment for CHS and VJ height, and 1RM power clean, back squat, and deadlift. Results: The average and peak of the control groups' CHS pre-test was 101.4 ±8.25 mph. After the 8-week study, the control group decreased CHS to an average of97.6 ±3.82 mph. The average of the control groups' VJ pre-test was 19.9 ±6.92 inches with a slight increase to 20.0 ± 1.235 inches with a peak VJ pre-test of 26.3± 7.2 inches (p=0.024). The average of the control groups' pre-test back squat 1RM was 201.7 ±81.4lbs. with a slight increase to 209.2 ±13.7lbs. and was found to be significant p=0.026. The average of the control groups' deadlift 1RM pre-test was 230 ±43.2lbs. and slightly increased to 244.2 ±14.0 lbs. post-test. However, the deadlift was not significant p=0.138. The average of the control groups' clean 1RM was 99.2 ±33.40 lbs. which increased to 111.5 ±10.9lbs. post-test (p=0.031). The average of the intervention groups' CHS pre-test was 101.36 ± 7.52 mph which increased to 104.6 ±2.47 mph post-test (p=0.004). The average for the intervention groups' VJ pre-test was 19.05 ±3.78 inches which improved to 21.25 ±1.40 inches post-test (p=0.024). The average back squat 1RM for the intervention group at pre-test was 216.6 ±82.0 lbs. which improved to 254.2 ± 32.36lbs. post-test, and reported significance p=0.026. The average deadlift 1 RM for the intervention group at pre-test was 257.5 ±86.2 lbs. which improved to 289.2 ±16.3 lbs. post-test, and reported no significance of p=0.138. The average clean 1RM for the intervention group pre-test was 117.5 ±43.2lbs., which improved to 148.8 ±14.6lbs. post-test, and reported significance of p=0.031. The Pearsons' correlation test reported 1RM back squat was significant (r=0.70, p=0.025), while the VJ trended towards significance (r=0.73, p=0.069). Conclusion: The results of this study revealed that an 8-week strength and power resistance training program increased muscular strength and based on a Pearsons' correlation was significantly related to CHS.
