Abstract
The ability to acutely enhance sports performance is a competitive advantage
for athletes. With the phonemenon of post activation potentiation, athletes can
achieve this ability. This study aimed to evaluate the post activation potentiation
(PAP) effect of an eccentric overload (EOL) exercise on sprint performance in
sprinters. Ten male sprinters (mean ± SD, age 24.90±2.60 years, weight
75.80±18, height 182.20±8.25, BMI 22.8 ± 1.22, and training experience
4.10±0.994 years) were involved in a randomised, crossover study. To evaluate
the post activation potentiation effect of EOL exercise, a 30-metre sprint test
was performed. The training protocol consisted of a parallel squat with a
flywheel ergometer. The participants performed 3 sets per 8 repetitions of EOL
parallel squats at an inertia of 0.06 kg.m² using a flywheel ergometer. Post
activation potentiation using an EOL exercise was compared with a control
condition (a standardised warm-up). The study consisted of three separate
sessions. The first session was familiarisation with protocols and equipment.
Sessions 2 to 3 were performed in a randomised order. These sessions are
separated by a 72-hour washout period. In one of the sessions that was the
control session, participants first performed a standardised warm-up and then a
30-metre sprint. In another session, participants first performed a standardised
warm-up, then the training protocols, and then, after 4 and 8 minutes, a 30-
metre sprint test. Post activation potentiation vs. control reported a meaningful
difference for 30-metre sprint time after 4 minutes (p < 0.05) and 8 minutes (p <
0.05). In conclusion, the present outcomes highlight that PAP using an EOL
bout improves sprint performance in sprinters.
