Purpose To study and compare the effects of supplementary legs muscular power training with pneumatic resistance combine sprint training with curve treadmill on sprint times of 5, 10, 20, and 50 meter in rugby football players.
Methods The subjects were 26 rugby football players of the Institute of Physical Education, Samutsakhon campus. There are 2 groups, The experimental group performed legs muscular power program with pneumatic resistance in weeks 1-4 at 50-60% of 1 RM 15-20 reps per set following sprint running 6-7 seconds, 3 sets, 3 minute rest between each sets, for total 30 minute, in weeks 5-8 at 70-80% of 1 RM 5-10 reps per set following sprint running 8 seconds, 3 sets, 3 minute rest between each sets, for total 30 minute, 2 days per week and practice routine rugby football training 90 minute, 5 days per week for total 8 weeks. The control group worked out only routine rugby football training program.
Results The study showed that average sprint times of 5, 10, 20, and 50 meter sprint between the stages of after 4th week and 8th week of training, before training and after 8th week of training were decreased significant difference at the .05.
Conclusion the effects of supplementary legs muscular power training with pneumatic resistance combine sprint training with curve treadmill can improve speed in rugby football players.
