Antagonist activation exercises elicit similar post-activation performance enhancement as agonist activities on throwing performance
Abstrakt
BackgroundThis study aimed to determine the acute effect of agonist and antagonist conditioning activities (CA) on medicine ball throw performance among female softball players.MethodsThirteen national-level female softball players (age 22.2 +/- 3.1 years; body mass 68.3 +/- 11.3 kg; softball experience 7.3 +/- 2.4 years) performed 3 medicine ball chest throws before conditioning activity (CA) and after CA respectively in 3rd, 6th, and 9th minute. CA was the bench press and bent-over barbell row with 2 sets of 4 repetitions at 60% and 80% of one-repetition maximum, and 2 sets of 4 repetition bodyweight push up.ResultsTwo-way ANOVA revealed an increase in throwing distance (p < 0.001) after bent over barbell row and push-up exercise, and an increase in throwing speed (p < 0.001) after bench press and push-up.
All performance increases were in moderate effect size (Cohen d 0.33-0.41), and no differences were found between the experimental CA.ConclusionsWe conclude that upper body throwing performance is similar after antagonist exercise and agonist CA, both agonist and antagonist CA increase muscle power. In the resistance training practice, we recommend the interchange of agonist and antagonist CA using bodyweight push-up or submaximal intensity (80% of 1RM) bench press and bent over barbell row to succeed post-activation performance enhancement in upper limbs.
