1 The Effectiveness of Ultra Short Race Pace Training on 11/12 USA Registered Females Roscoe Potts HES00272: Technology & Assessment in Health & Exercise Science Dr. Peter Rattigan July 27, 2015 Rowan University

2 Purpose of this Study: Determine the effectiveness of Ultra- Short Race Pace Training (USRPT) on 11/12 USA registered females

3 What is USRPT? Introduced by Dr. Brent S. Rushall (formerly of San Diego University) 1 Based on the science of developing alactacid production 2 Anaerobic energy source for the first seconds of intense exercise Quick recovery and no lactic acid buildup Ideal set: 20 x 20m at race pace on a 20 second interval 1 Thompson, Daniel, III.

4 How is USRPT a Departure from Traditional Training Methods? Traditionally: Sprinting takes place at the end of a practice Training sets often encompass thousands of yards Sprinting often occurs for up to 100 yards Dry lands training often accompanies practice Lactic acid often builds up during sets

5 How to Measure the Effectiveness of USRPT on 11/12 USA Registered Females 50 yard freestyle time trials Pre-season Prior to first practice of season Mid-season 4 ½ months into the season Post-season Last week of practice for the season

6 Sample Intake Form Name Birthday Age (as of 6/30/15) Jennifer Smith (ex.) Weight (lb.) Height (in.) Pre-season 50 free Mid-season 50 free 7/21/ Postseason 50 free

7 Testing Parameters Same coach assigned for all three tests for each subject Same brand of stop watches used Occurred at the subjects regular practice facility No technical suits permitted Time trial occurred after a 100 yard warm-up 12 yards hard sprinting 88 yards slow, stretched out freestyle

8 Descriptive Statistics Age Weight (lb.) Height (in.) Pre-Season 50 Free Mid- Season 50 Free Post- Season 50 Free Time Improve ment Mean SD P-Values Correlation -.89

9 Results:

10 Results:

11 Outcomes Mean Weight: Just below 50 th % for girls aged 11/12 1 Mean Height: Between 50 th and 75 th % for girls aged 11/12 1 Height and Weight Conclusion: Assists in validating results not tied to physical stature 1

12 Correlation / Two-Tailed Type 1 T Test Correlation between Pre-Season Time/Improvement Time -.89 Time improvement can be attributed to USRPT P Values Significant result for pre- to mid- season time drops Insignificant result for mid- to post-season time drops

13 Interpretation of Results Easier to drop time for first half of season Harder to drop time for last half of season Slower swimmers had more significant time drops Overall time drops can be attributed to USRPT

14 Reflections & Conclusions Future study could use older subjects Done growing and developing Time drops won t be attributable to physical changes Can accept USRPT as standard from of training sprinters Study did not rule out any other training techniques
