Abstract: (145 Views)
Background. Post-activation potentiation (PAP) occurs after a previous potentiating stimulus (PP) and causes a sudden increase in muscle strength and performance. After muscular effort, this acute phenomenon manifests itself only if the athlete has rested enough. Fatigue is the ratio between excitation and contraction, dependent on physical activity. If, after performing physical activity with the purpose of potentiation, fatigue is present together with potentiation, fatigue will always prevail.
Objectives. This study examined two different isometric methods for enhancing post-activation performance in track and field athletes.
Methods. The study sample consisted of 25 Croatian track and field athletes who compete in speed-explosive disciplines. The athletes were divided into two groups. One group performed a maximal isometric half-squat protocol (HS; pushing a stationary Olympic bar), and the second group performed maximum voluntary contraction (MVC) on the quadriceps and femoris muscles.
Results. Both groups performed an initial test, then a potentiating stimulus, and after a 5-minute rest, performed the final test again. The dependent t-test results showed no statistically significant difference between the initial and final measurements in the MVC group (p=0.39) and the HS group (p=0.80).
Conclusion. The isometric preparation protocols cannot positively influence the post-activation performance increase in the best Croatian athletes. No single protocol is more effective than the other.

APPLICABLE REMARKS
APPLICABLE REMARKS
- The measurements of the maximal voluntary contraction of the quadriceps femoris muscle protocol showed a small but insignificant improvement in the jump height after the protocol was implemented. With the maximum isometric half-squat protocol, the measurements showed a small but statistically insignificant regression in the results. No single protocol has been shown to be more effective than the other.
- All jump height measurements were made in the Kinovea program, which has been repeatedly proven reliable and valid. Although Kinovea is a reliable tool for this kind of measurement, the quality of the analyzed video also plays a significant role. The recommendation for future research would be to set the camera settings to more than 240 frames per second when recording the subjects' attempts.
