Delayed-onset muscle soreness in the gastrocnemius muscle of healthy collegiate students following unaccustomed high-intensity eccentric exercise. The condition is characterized by muscle pain, tenderness, stiffness, swelling, decreased muscle strength, reduced joint range of motion, and temporary loss of muscle function. Symptoms typically appear 8 to 24 hours after eccentric exercise, peak within 48 to 72 hours, and gradually subside over approximately one week. The study focuses on physically
Conditions
Interventions
Device and Parameters: A commercially available pneumatic leg massager was used with a pressure setting of 50-80 mmHg (moderate intensity suitable for muscle fatigue relief as per the instrument manua
s pain threshold ranging from 2 to 3 kg per square centimeter. This pressure range was determined individually for each participant using the WE Algometer a validated pain threshold measurement device
