EFEKTIVITAS PELATIHAN DOUBLE LEG BOUND TERHADAP DAYA LEDAK OTOT TUNGKAI

Based on observations made at the Gianyar State Vocational School, it was obtained data that the explosive power of the students' leg muscles was still at a low level. Related to this, research is carried out related to the explosive power of leg muscles through double leg bound training. The purpose of this training is to determine the effectiveness of double leg bound training on leg muscle explosive power. The research sample amounted to 50 people who came from all students of class number XI state high school Gianyar with the study population sampling technique. The results showed that double leg bound training increased leg muscle explosive power by obtaining a mean difference in the treatment group of 5.68 cm and 2.56 cm in the control group with a percentage increase of 11.15% for the treatment group and 5.04% for the control group.
