简要总结
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.

研究组 & 干预措施
Volume Training Group
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.
干预措施: plyometric training protocol (Other)
Reduced Volume Training Group
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.
干预措施: plyometric training protocol (Other)
Control Group
Participants in this group will not undergo any plyometric training and will serve as a comparison to assess the natural progression of lower limb strength, power, and muscle activity without intervention.
