Abstract
Introduction: The explosive strength of the lower limbs was a crucial physical ability for the jumping events in athletics, and its objective assessment became essential in regional competitions.
Objective: Measure the explosive strength of the lower body in male jump athletes from the field trials of the Bolívar Athletics League, Colombia, to characterize their explosive strength.
Methodology: The research was approached from a quantitative perspective, with a non-experimental, descriptive, and cross-sectional design. The sample consisted of twenty-five male athletes. The evaluation was carried out using a standardized Squat Jump protocol and the data were analyzed with descriptive statistics.
Results: The average jump height was 19.97 cm in the first measurement, 23.19 cm in the second, and 26.27 cm in the third. The dispersion of the data was moderate, with standard deviations of 4.42, 5.86, and 5.82 cm, respectively. The minimum values ranged between 10.60 and 12.76 cm, and the maximums reached up to 37.28 cm, demonstrating the great interindividual variability of explosive strength power.
Discussion: The comparison with the scientific literature supported the use of the Squat Jump to assess explosive power and demonstrated that the variability found matched the neuromuscular differences observed in jump athletes.
Conclusions: It is determined that the assessment of explosive strength thru the Squat Jump is a way to objectively characterize the performance of athletes in regional leagues.
