RELATIONSHIP BETWEEN HIGH AGENCY AND POWER MUSCLE TUNGKAI ON THE ABILITY OF STAFF LONG STUDENTS SMP NEGERI 1 AMPEK BALAI TAPAN

Abstrak

A long jump is a jumping motion that uses a pedestal on one foot to reach a distance as far as possible. The goal and purpose of long jump is to achieve the greatest jump distance to a landing or jump point. The jump distance is measured from the repulsion boards to the nearest limit of the landing points generated by the body parts. According to Adang Suherman (1992: 36). Long jump is the movement of motion movement from one place to another with a repulsion forward as far as possible.

            The type of research is correlational with the population is the students of SMP Negeri 1 Basa Ampek Balai Tapan. Sampling in this study by using the total sampling of all students of SMP Negeri 1 Basa Ampek Balai Tapan which amounted to 59 people. Data taken in three ways measures height for height and Standing Broad jump for leg muscle power, long jump measuring student long jump. The data obtained in the analysis using product moment correlation formula and multiple correlation.

            The result of the research with significant level (a = 0.05) showed that: (1) there was a correlation between height and ability of long jump student of SMP Negeri 1 Basa Ampek Balai Tapan with simple correlation result of robs 0,351> rtab 0,254, tobs 2,826> ttab 1,671, 2) there is correlation between leg muscle power with ability of long jump student SMP Negeri 1 Basa Ampek Balai Tapan with result of simple correlation robs 0,417> rtab 0,254, tobs 3,453> ttab 1,671, (3) there is relation between height and power muscle leg together -together with the long jump ability of SMP Negeri 1 Basa Ampek Balai Tapan with a simple correlation result Robs 0,443> Rtab 0,254, Fobs 6,845> ftab 1,56.

            There is a significant correlation between the height of ability of long jump student of SMP Negeri 1 Basa Ampek Balai Tapan (X1). There is a significant correlation between limb muscle ability of long jump ability of SMP Negeri 1 Basa Ampek Balai Tapan (X2) students. There is a significant relationship between height and leg muscle power together with the ability of long jump student SMP Negeri 1 Basa Ampek Balai Tapan (Y).

Key Wort : height, leg muscle power, long jump ability.
