OBSERVATIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria1
- Weightlifters younger than 15 years old and older than 18 years old (up to 23 years), registered to compete in the 2025 "El Pavo" National Tournament with no declared health issues.
Exclusion Criteria1
- Weightlifters registered for the 2025 "El Pavo" National Tournament who present any declared health issues.

Interventions
The participants' force production capacity will be assessed. The test will be conducted on a force platform. Each athlete will perform general and specific warm-up and familiarization with three isometric attempts with CJ grip (\~50%, 80% and 100% perceived effort). For measurement, each participant will execute two 3-s maximum attempts with CJ grip, with 1 minute rest between efforts.
A force platform will be used to measure the lower-limbs vertical impulse during a The Deep Squat Jump (DSJ). Participants will execute the DSJ without any countermovement, ensuring maintenance of the full squat position for 3-4 seconds before takeoff to avoid any contribution from elastic energy storage.
Performance indicators will be obtained from official competition records, extracting the best valid loads in Snatch (SN), Clean \& Jerk (CJ), and Total (TOT)
