About this study
Official title: Comparing the Effects of Post Activation Potentiation on Vertical Jump Using High-Intensity Back Squat vs. Wingate Bike Test in Healthy Adults
The goal of this trial is to see if using a maximal effort, short cycling test is better at activating muscles to improve vertical jump height compared to a maximal effort back squat. The study looks to answer three questions:
- will the Wingate bike test create a different change in counter movement jump height compared to a back squat?
- What is the best recovery period after each test where the counter movement jump is the highest?
- What person-specific factors predict success of the Wingate bike test as a activation activity for the counter movement jump? Participants will visit the lab 3 times, once to give informed consent and measure their 1 repetition max (RM) back squat, and twice to perform each intervention and measure vertical jump height.
Read the detailed description
Participants will be asked to come to the lab for three visits. On the first visit, they will perform informed consent, have anthropometrics taken, and will provide data to assess weightlifting history and factors that may influence the impact of each intervention. They will perform a 1 repetition max (RM) test for the back squat in order to properly dose the back squat potentiation activity. Visits 2 and 3 will be randomized; one will use the back squat (control) and the other will use the Wingate bike test (experimental) to potentiate vertical jump height as measured by the counter movement jump (CMJ). In each session, a warm up will be performed and the baseline CMJ will be performed. The intervention will be performed, either the 30 second Wingate protocol which is a maximal effort cycling test, or the back squat at a high percent of the 1 RM. The CMJ will be reassessed at 3, 6, and 9 minutes after completed each intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Back squatOther
2 sets of 3 repetitions of a back squat, set to 85% of the 1 repetition maximum weight
Wingate testOther
30 second maximal effort cycling test, with resistance at 7.5% bodyweight
| Study group | Role | What they receive |
|---|---|---|
| Back squat | Active comparator | Participants will perform 2 sets of 3 repetitions at 85% of their 1 repetition maximum weight for the back squat Receives: Other: Back squat |
| Wingate test | Experimental | Participants will perform the Wingate bike test, with resistance at 7.5% of body weight, with a maximal effort for 30 seconds. Receives: Other: Wingate test |
What is being measured
The primary outcome is the main question the study is designed to answer.
Vertical Jump Height
Measured with the Counter Movement Jump (CMJ). This measures the vertical distance a participant is able to jump from a standing, stationary position. Video capture and motion analysis software will be used to analyze the jump and determine vertical displacement of a marker placed at the participants sacrum. Vertical jump height will be measured in meters.
Measured: Visit 2 (1 week post- enrollment); visit 3 (2 weeks post-enrollment)
Secondary outcomes (2)
Years of resistance training experience
This factor will be collected to examine its predictive impact on the Wingate test's potentiation effect. The number of years of resistance training each participants has participated in will be collected.
Measured: Collected at visit 1, upon enrollment into the study
One-Repetition Maximum Back Squat Strength
This factor will be collected to examine its predictive impact on the Wingate test's potentiation effect. The 1 repetition maximum weight in kilograms for the back squat exercise will be collected.
Measured: Collected at visit 1, upon enrollment into the study

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?
Vertical Jump Height (time frame: Visit 2 (1 week post- enrollment); visit 3 (2 weeks post-enrollment)). 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 NCT06779409, which also lists 5 linked publications.
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 4 Jul 2025.
