About

This study aims to determine whether, within each weight and sex category, higher isometric pull force or greater vertical jump impulse is associated with better final placement in the competition.

Full description

This cross-sectional observational study will be conducted during the 2025 "El Pavo" National Tournament, held in San Luis Potosí, Mexico, with athletes officially registered with the Mexican Weightlifting Federation (FMLP). Vertical jump impulse will be assessed using the Deep Squat Jump (DSJ) approximately two hours after each athlete's last valid attempt, followed by the Isometric Pull Start Position (IPSP) test to measure isometric pull force. Competitive performance data-best Snatch (SN), Clean & Jerk (CJ), and Total (TOT)-will be obtained from official competition records, along with the athlete's final placement within their sex and body mass category.

The study will analyze athletes from two age groups (U-15 and Over-18) and both sexes, selecting one light and one heavy body mass division per group. The included divisions are: U-15, Female: -44 kg (light), -63 kg (heavy) and Male: -56 kg (light), -79 kg (heavy); Over-20, Female: -53 kg (light), -77 kg (heavy) and Male: -65 kg (light), -94 kg (heavy)
