About this study
Official title: Cluster Versus Traditional Set Configurations in Plyometric Training; Acute Neuromuscular, Metabolic, and Perceptual Responses in Young Soccer Players
The purpose of this study is to compare the effects of two different plyometric training methods (cluster sets versus traditional sets) on young male soccer players. The study investigates how these two training structures affect players' jumping performance, muscle fatigue, heart rate, blood lactate levels, and how hard they feel they are working (perceived exertion). Twenty amateur soccer players performed two jump training sessions on separate days. One session used a traditional method (3 sets of 9 jumps with 80 seconds rest between sets), and the other used a cluster method (9 sets of 3 jumps with 20 seconds rest between sets). Both methods involved the same total number of jumps (27 jumps) and the same total rest time (160 seconds). The goal is to determine if breaking the exercise into smaller "clusters" with more frequent, shorter rests helps athletes maintain their explosive power better and reduces fatigue compared to the traditional method.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Traditional Set ConfigurationOther
Participants performed a total of 27 countermovement jumps organized into 3 sets of 9 repetitions. An inter-set rest period of 80 seconds was provided between the sets, resulting in a total rest time of 160 seconds for the session.
| Study group | Role | What they receive |
|---|---|---|
| Traditional Set Arm | Experimental | Participants performed a total of 27 countermovement jumps organized into 3 sets of 9 repetitions. An inter-set rest period of 80 seconds was provided between the sets, resulting in a total rest time of 160 seconds for the session Receives: Other: Traditional Set Configuration |
| Cluster Set Configuration | Experimental | Participants performed a total of 27 countermovement jumps organized into 9 cluster sets of 3 repetitions. A short rest period of 20 seconds was provided between each cluster set, resulting in an equated total rest time of 160 seconds for the session. Receives: Other: Traditional Set Configuration |
What is being measured
The primary outcome is the main question the study is designed to answer.
Countermovement Jump (CMJ) Height
Mechanical fatigue and lower-body explosive power assessed via countermovement jump performance
Measured: Pre-training and immediately post-training
Secondary outcomes (2)
Blood Lactate Concentration
Metabolic response measured via capillary blood lactate samples.
Measured: Pre-training and immediately post-training
Heart Rate (HR)
Physiological cardiovascular response monitored during and after the training sessions.
Measured: Continuously during the session and immediately post-training

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?
Countermovement Jump (CMJ) Height (time frame: Pre-training and immediately post-training). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07843069, which also lists 1 linked publication.
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 28 Sep 2026.
