About this study
Official title: Determining the Minimum Effective Volume of Plyometric Training for Inducing Changes in Lower Limb Strength, Power, and Muscle Electrical Activity During Functional Performance Testing in Sedentary Individuals
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?
Read more
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
plyometric training protocolOther
The plyometric training program will last for 4 weeks, with three sessions per week. The plyometric exercises will be performed immediately after a warm-up. The program will incorporate bilateral, unilateral, acyclic, cyclic, horizontal, vertical, lateral, and diagonal movements involving both slow and fast movements.
Each session will include 4-5 plyometric exercises, with 2-10 sets per exercise and 1-10 repetitions per set. The training volume will progressively increase from the 1st to the 2nd week and then the intensity will increase while the volume decreases from the 3rd to the 4th week in both intervention groups. However, the final volume will vary by 50% between the groups.
| Study group | Role | What they receive |
|---|---|---|
| Volume Training Group | Experimental | 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. Receives: Other: plyometric training protocol |
| Reduced Volume Training Group | Experimental | 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. Receives: Other: plyometric training protocol |
| Control Group | No intervention | 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. |

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline muscle strength at 4 weeks (time frame: Baseline (pre-intervention), and two days after the last training session). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2024.
