English abstract
Scientific background: The recovery time after Post activation potentiation using
weights may have a positive or negative effect on physical requirements such as
strength, speed, and muscle ability. The research aims was to study the effect of
recovery time after Post activation potentiation using heavy weight exercises on arms
muscle power.
Methodology: Thirteen students from the department of Physical Education and
Sports Science at Sultan Qaboos University (21.05 ± 1.1 years) Participated in this
study. The Participants visited the sport hall at Sultan Qaboos University eight times.
The visits from 1-5 were assigned to get used to the Wingate test, as well as to do
two measurements of Wingate test for each individual sample to study the reliability of
the test, and also measure the maximum frequency of each player (one repetition
maximum – 1RM). During the following visits, three investigated positions have been
applied randomly: the recovery times 3 or 5 or 7 minutes after Post activation
potentiation by 3 sets of 6 repetitions at 45% of RM.
Results: The results of the study showed that there are statistically significant
differences between the three recovery times for absolute and relative arms peak and
mean power. The results also indicated that the effect of recovery time 5 and 7
minutes on muscle arms power is better compared to recovery time of 3 minutes. The
results also showed no statistically significant differences between recovery times 5
and 7 minutes.
Conclusion: The study concluded that recovery times 5 and 7 minutes after Post
activation potentiation using strength exercises at 45% of RM have an appositive
effect on maximum muscle power and on the mean power
