| Summary: | The purpose of this study is to compare the differences between 4 minutes of rest
interval and 8 minutes of resting interval on sprinting performance among adolescent
athletes. A total of thirteen subjects (N=13) of Selangor Sports School athletic athletes was
selected through purposive sampling. This study compared the differences between 4 minutes
and 8 minutes of rest interval on sprinting performances. On the first day session, all of the
subjects performed the plyometric (Post-activation Potentiation) exercise which is the athletes
performed 3 sets of 10 alternate-leg bounds (5 contacts per leg per set), with 25 seconds each
set recovery time with 4 minutes of rest interval after completed the 3 sets. The 30 meter
sprint time was measured with a handheld stopwatch immediately after 4 minutes of the rest
interval. On the second day session of this study, the same method was used for 8 minutes of
rest interval on sprinting performance. Paired Sample T-test was used to analyze the data
between 4 minutes and 8 minutes of rest interval on sprinting performance. The hypothesis
was significant differences between 4 minutes and 8 minutes of rest interval after Post Activation
Potentiation activities on sprinting performance (M=0.08, sd=0.03). The overall
result also indicated that 4 minutes of rest interval on sprinting (M=4.22, sd = 0.10) was
better than 8 minutes of rest interval on sprinting (M=4.31, sd = 0.11). Hence, from this
study, the result can conclude 4 minutes of rest interval has been associated with better
muscular explosives and helps in improving the sprinting performance.
