About this trial
This study will investigate how different warm-up strategies affect physical performance in female athletes who practice invasion sports (e.g., soccer, handball, and basketball). Participants will complete three different conditions: a standard warm-up only, a warm-up followed by a performance-enhancing activity, and a warm-up followed by a low-intensity activity designed to simulate the same expectations without real physiological effects.
After each condition, athletes will perform tests of vertical jump performance and change-of-direction speed. In addition, participants will report their perceived effort, expectations, muscle soreness, and recovery status.
The study will include eighteen female athletes and will be conducted under controlled conditions, including standardized hydration, recovery, and environmental factors. The design will allow comparison of the physical and psychological effects of the different warm-up strategies on performance.

Treatments tested in this trial
post-activation performance enhancement (PAPE) protocol
Other interventionThis study uses a randomized crossover design in which participants complete three conditions (real conditioning activity, SHAM, and control), reducing inter-individual variability. A key feature is the SHAM condition designed to control for placebo and expectancy effects, combining low-load resistance exercise (20% 1RM), verbal suggestion, and simulated blood flow restriction (15 mmHg), insufficient to induce physiological responses. All conditions are strictly standardized, including a warm-up, metronome-controlled cadence, fixed rest intervals, and equal total duration. The conditioning activity (drop jump) is performed at maximal intensity with individualized box height and standardized technique. The study focuses exclusively on female athletes and includes evaluator blinding, addressing gaps in research and improving control of psychophysiological influences on performance.

Trial outcomes
Primary outcomes
1
Countermovement Jump Height
Countermovement jump height (cm), assessed under standardized conditions using a contact mat. Participants will perform three attempts, and the mean value will be used for analysis. Jumps will be executed with hands on hips to minimize upper-body contribution. Measurements will be collected at baseline and after each experimental condition to evaluate changes in performance.
Time frame
Baseline (pre-intervention) following each experimental condition within the same session.Secondary outcomes
1
Agility Performance
Agility performance assessed by the 5-10-5 change of direction test (seconds), measured under standardized conditions using photocell timing gates. Participants will perform three attempts, and the mean time will be used for analysis. The test consists of sprinting 5 meters to one side, 10 meters to the opposite side, and 5 meters back to the starting point. Measurements will be collected at baseline and after each experimental condition.
Time frame
Baseline (pre-intervention) and after the countermovement jump assessment (following each experimental condition).2
Participant Expectation
Participant expectation assessed using a bipolar Visual Analog Scale (-500 to +500), used to quantify perceived effectiveness and potential placebo/nocebo effects. Participants will rate their expected change in performance following each experimental condition. Assessments will be conducted immediately after each condition and prior to performance testing.
Time frame
