This randomized controlled trial aims to investigate the acute effects of two passive warm-up methods-infrared heating and therapeutic massage-on vertical jump, horizontal jump, dynamic balance, static balance, and lower extremity muscle flexibility in healthy adults.

5 minutes of cycling warm-up 10 minutes of infrared application to dominant quadriceps Infrared applied at 90° angle on bare skin while participant rests in prone position Mechanism: IR-induced deep tissue heating increasing molecular activity and passive warm-up effect
5 minutes of cycling warm-up 10 minutes of standardized classical massage applied by trained personnel Techniques used: Stroking (effleurage), local stroking, kneading (rolling technique) Massage oil warmed in hands prior to application

Time frame: Baseline (Pre-intervention)
Dynamic Balance Composite Score
The Y-Balance Test is a dynamic balance assessment tool used to evaluate an individual's ability to maintain postural control while reaching in multiple directions. The participant stands on one leg at the center of a Y-shaped grid and reaches as far as possible with the contralateral leg in three directions: anterior, posteromedial, and posterolateral. The maximum reach distance for each direction is measured in centimeters (cm) and normalized to leg length to reduce inter-individual variability. Outcome Metrics: Reach distance (cm) in the anterior, posteromedial, and posterolateral directions Dynamic Balance Composite Score (%) =(Sum of the 3 reach directions / 3 times the limb length \* 100)
Time frame: Baseline (Pre-intervention)

Flamingo Static Balance Test Score
A balance beam (50 cm long, 4 cm high, and 3 cm wide) and a stopwatch will use. Participant stands on the balance beam with one leg and bents the free leg backward and grip the back of the foot with the hand on the same side, standing like a flamingo. Participant attempts to maintain this position for as long as possible. The time stops if the raised leg touches the ground, and restarts when balance is regained. The test is scored based on the number of mistakes made within one minute. The more mistakes made, the lower the score.
