Effects of an Isometric Training Session on Post-exercise Neuromuscular Function When Compared to Dynamic Strength Training
A study testing strength training in people with Strength Training Effects, run by University of Maia at 1 site in Portugal.
Trial summary
The existing literature shows that maximum strength can be improved through both dynamic and isometric strength training. However, there is a perception that dynamic training has a negative effect on short-term neuromuscular performance in soccer players. Read more about this study

About this study
Official title: Effects of an Isometric Training Session on Post-exercise Neuromuscular Function When Compared to a Dynamic Strength Training Session in Youth Soccer Players
The existing literature shows that maximum strength can be improved through both dynamic and isometric strength training. However, there is a perception that dynamic training has a negative effect on short-term neuromuscular performance in soccer players. Hence, the aim of this study was to compare the neuromuscular impairment after isometric and dynamic training sessions in young soccer players.

Clinical summary

However, there is a perception that dynamic training has a negative effect on short-term neuromuscular performance in soccer players. Hence, the aim of this study was to compare the neuromuscular impairment after isometric and dynamic training sessions in young soccer players.

Questions about this trial
What is this clinical trial studying?
A study testing strength training in people with Strength Training Effects, run by University of Maia at 1 site in Portugal.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.
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 (time frame: baseline (pre-test), 30 minutes and 24 hours post intervention). The study lists 2 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 1 Aug 2025.
