| Popis: | Interval tennis rehabilitation programs (ITRPs) are advocated during later stages of shoulder and elbow rehabilitation. ITRPs utilize gradual increases in hitting or serving effort, based on perceived effort. Over-estimation of effort may increase stress. This investigation purpose was to determine actual tennis serve velocity when asked to hit serves at perceived effort of 50%, 75%. Thirty-nine healthy college tennis players performed a warm-up of groundstrokes and serves. Five maximal effort serves (100% velocity) functioned as the 100% maximal effort serve. Then, five serves were hit at each of two randomly determined velocities. The average of five trials for maximum effort (100% velocity) was calculated. Based on this number, 75% and 50% of maximum velocity was determined. Using one-sample t-tests, the subjects’ perceived efforts were compared against computed percentages. Differences were found between perceived effort and calculated percent. Overall, actual velocity served was greater than percieved. Because velocity at 100% effort was significantly different for males and females, a separate analyses was done by gender. Both males’ and females’ perceived velocities were significantly greater (p |
