EFFECTS OF TWO PLYOMETRIC TRAINING PROGRAMMES OF DIFFERENT INTENSITY ON VERTICAL JUMP PERFORMANCE IN HIGH SCHOOL ATHLETES

摘要: Although plyometric training is a significant component of most conditioning programme designs, little research exists with regards to the design/structure specific interventions and intensity involved. The aim this study was compare effect manipulation on 6-week programmes vertical jump performance. Eighteen healthy adolescent male subjects were randomly allocated periodised (INCR), constant moderate (CONS) control (CONT) group, for 6- week programme. Pre- post-training measurements net impulse, take-off velocity, height peak force calculated from countermovement jump. Contact time flight time, rebound reactive strength index drop INCR CONS groups achieved improved performance compared CONT (P 0.05) between any variables, there trend greater improvement group. In conclusion, exercise short duration could be less than intervention itself. Longer durations density as well consideration exercises merit further investigation.
