Neuromuscular Variables and Performance in Mexican Weightlifters

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.

Conditions

• Isometric Muscle Strength
• Jumping Performance
• Weightlifting
• Performance Measures

Interventions

OTHER

Isometric start position pull (ISPP)

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.

OTHER

Vertical impulse

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.

OTHER

Performance

Performance indicators will be obtained from official competition records, extracting the best valid loads in Snatch (SN), Clean \& Jerk (CJ), and Total (TOT)
