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

Not Applicable

Completed

• Conditions: Sedentary Behavior; Plyometric Exercise
• Interventions: Other: plyometric training protocol

• 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.

Arm && Interventions

Group	Intervention	Description
Volume Training Group	plyometric training protocol	Participants in this group will undergo a plyometric training protocol at a known effective volume that is expected to induce changes in lower limb strength, power, and muscle activity.
Reduced Volume Training Group	plyometric training protocol	Participants in this group will undergo a plyometric training protocol at a lower volume than the Volume Training Group, aiming to determine if a lower volume still leads to significant improvements in lower limb strength, power, and muscle activity.

Primary Outcome Measures

Name	Time	Method
Change from baseline muscle power at 4 weeks	Baseline (pre-intervention), and two days after the last training session	level of lower limb muscle power during an instrumented sit to stand test
Change from baseline muscle strength at 4 weeks	Baseline (pre-intervention), and two days after the last training session	level of lower limb muscle strength during an instrumented sit to stand test
Change from baseline muscle activity at 4 weeks	Baseline (pre-intervention), and two days after the last training session	level of lower limb electromyographic activity during an instrumented sit to stand test
