The main aim of this study is to investigate the acute effects of cryotherapy on muscle mechanical properties, muscle strength, and activation changes in healthy subjects.

What changes occur in muscle stiffness following cryotherapy application? How does cryotherapy affect muscle strength? How does cryotherapy impact muscle activation? Are there differences in muscle mechanical properties, muscle strength, and muscle activation between different cryotherapy methods (ice massage and cold spray)? How do the effects of cryotherapy on muscle mechanical properties, muscle strength, and muscle activation change over time?

Inclusion Criteria:

• Being willing to participate in the study
• Being between the ages of 18 and 35

Exclusion Criteria:

• Having undergone orthopedic surgery involving the lower extremity
