Efficiency in 4-week Plyometric Training: Lower Limb Improvement in Sedentary Adults

Not Applicable

Completed

• Conditions: Sedentary Behavior; Plyometric Exercise

• Registration Number: NCT05928130
• Lead Sponsor: Rodrigo Lizama Perez

Brief Summary

The goal of this clinical trial is to compare the effects of different volumes of plyometric training on lower limb muscle strength, power, and muscle activity in sedentary individuals. The main question\[s\] it aims to answer are:

* What is the minimum volume of plyometric training that can induce changes in lower limb strength and power variables?

* How does muscle activity in the lower limbs vary with different volumes of plyometric training?

Participants will be asked to:

* Complete questionnaires to determine their level of physical activity.

* Attend pre and post-evaluations of lower limb muscle activity, strength, and power during an instrumented sit-to-stand test.

* Perform lower limb plyometric exercises, such as jumps, hops, and bounds.

* Attend supervised training sessions three times a week for a duration of 4 weeks.

Researchers will compare three groups to see if the minimum volume of plyometric training can be identified.
