Effect of Weight Training on Increasing 100 Meter Running Speed in Sprinter Athletes Based on Gender

The aim of this study was to investigate the effect of weight training on the performance of 100meter spinner athletes based on gender. This research is one group pretest – posttest. Samples on athletes were carried out voluntarily provided that they were not injured and were not taking part in a competition period. The sample consisted of 10 male sprinters (mean: height 170.2±0.6 cm, weight 64.2±2.7, body mass index (BMI) 21.27, training experience 5.6±7.8 years) and 10 female sprinters (mean: height 168.7±7.2, weight 53.7±0.6, body mass index (BMI) 18.14, training experience 5.2±14 years) with age 17 – 22 years. The test for pretest–posttest is 100 meters run, while determining the load volume uses the 1RM Brzycki formula. This training program is carried out for 6 weeks (3 times a week), training volume 40% - 60% with 3 sets x 8 repetitions, types of weight training are bench press, deadlift, leg press, half squat, double leg bounds. The results of the t test, this research shows that weight training has an effect on increasing the 100 meters sprint of male athletes by 0.000 < 0.05 with an increase in time of 0.33 seconds. Then weight training has an effect on increasing the 100 meters sprint of male athletes by 0.000 < 0.05 with an increase in time of 0.20 seconds. The recommendation of this research is to train at the general preparation stage, because this weight training using 2 supports on the right and left sides of the hands and feet.
