The problem in this research was the lack of explosive power leg muscle in the athletes smash and block when doing smash and block, it was still not optimal or still low. This was evident when they exercised and competed, their smashed were in netted and out, moreover the blocks were not able to reach the ball, so the team got an attack from opponent team very easy. This research was conducted …
The problem in this research is based on the statement submitted to the lecturers who have authority during the lecture activities, student IVA Education Sports coaching is still said to be weak in the power aspect. This is evidenced by the number of female students who are unable to achieve the standard that has been determined by the lecturer. In addition, it is also seen when rejecting femal…
Base on field observations conducted by researchers, that there are some problem or phenomena that occur in the game extracurricurel football SMK Kehutanan Pekanbaru, namely the lack of mastering technique of playing the ball. such as dribble ie the ball is often dribbled away from the foot of the player, ball contol is not good when dribbing, so players often lose the ball while dribbling. the…
