Preconditioning Strategies Before Maximum Clean Performance in Female Weightlifters

Area of Science:

• Sports Science
• Strength and Conditioning
• Olympic Weightlifting

Background:

• Optimizing performance in Olympic weightlifting requires understanding effective pre-exercise strategies.
• Preconditioning protocols aim to enhance acute performance through specific preparatory exercises.

Purpose of the Study:

• To investigate the acute effects of clean pulls at 85% and 120% of one repetition maximum (1RM) on subsequent clean performance in female Olympic weightlifters.
• To compare the rate of perceived exertion (RPE) between the two preconditioning loads.

Main Methods:

• Eight competitive female Olympic weightlifters performed clean pulls at 85% or 120% 1RM, followed by a maximal clean attempt.
• Counterbalanced order was used across two separate testing days, with a 3-minute interval between preconditioning and maximal effort.
• Evaluated metrics included clean performance, RPE, countermovement jump (CMJ), and isometric leg press force development.

Main Results:

• Clean performance significantly increased by 6.1% after 85% 1RM preconditioning and 4.7% after 120% 1RM preconditioning.
• Rate of perceived exertion was significantly lower following the 85% 1RM preconditioning compared to the 120% 1RM.
• No significant correlations were found between performance improvements and body composition, CMJ, or isometric leg press parameters.

Conclusions:

• Both 85% and 120% 1RM clean pull preconditioning are effective for acutely enhancing clean performance in female Olympic weightlifters.
• The 85% 1RM load appears to be a more favorable preconditioning strategy due to lower perceived exertion.
