An interventional study of Back squat and Wingate test in Performance Enhancement and Muscle Activation, sponsored by Louisiana State University Health Sciences Center Shreveport. Completed at 1 site in United States. Open to participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-07-04.

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:
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.
Exclusion Criteria:
Participants will perform 2 sets of 3 repetitions at 85% of their 1 repetition maximum weight for the back squat
Other: Back squat
Participants will perform the Wingate bike test, with resistance at 7.5% of body weight, with a maximal effort for 30 seconds.
Other: Wingate test
2 sets of 3 repetitions of a back squat, set to 85% of the 1 repetition maximum weight
30 second maximal effort cycling test, with resistance at 7.5% bodyweight
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.
Time frame: Visit 2 (1 week post- enrollment); visit 3 (2 weeks post-enrollment)
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.
Time frame: 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.
Time frame: Collected at visit 1, upon enrollment into the study
Plan to share: Yes — All of the individual participant data collected during the trial, after deidentification.
