PENGARUH LATIHAN HEXAGONAL OBSTACLE TERHADAP PENINGKATAN DAYA LEDAK POWER OTOT TUNGKAI

Abstract

Power is the power and speed of muscle contraction is dynamic and explosive and involves
the expenditure of maximum muscle strength in the fastest time. Explosive power is one component
of physical condition that is needed in sports. This is supported by the opinion of Sukadiyanto
(2011: 128) power is the result of times between strength and speed. To that end, the sequence to
increase power is given after the athlete is trained element of strength and speed. According to
Riaydi, (2010) explosive power is a person's ability to use maximum capabilities deployed in the
shortest time. The obstacle hexagonal jump is done quickly so that the movements performed are
explosive or abrupt so as to have an effect on the increase of explosive muscle limb power. The
result of statistical analysis showed that the mean for the treatment group was 2.90 while the mean
for the control group was 1.55 this indicated that the mean group of threatment was greater than the
control group. While the results of the threatment group analysis is known that the t-test value is
11.599 with the standard deviation of 1.119 and for the control group that the t-test value is 9.131
with the standard deviation of 0.759, thus there is indeed the effect of obstacle hexagonal exercise
on increasing the muscle explosive power ) leg muscles.
