About

This study investigated whether muscle damage induced by a drop jump protocol varies based on participants' body weight and BMI. Fifty healthy adults were divided into normal-weight and overweight groups. All participants completed a standardized drop jump protocol, and blood samples were collected before, immediately after, and 24 hours after exercise. Creatine kinase (CK) and lactate dehydrogenase (LDH) levels were analyzed as biomarkers of muscle damage.

50 participants in 2 patient groups

Normal Weight Group

Experimental group

Description:

Participants with a Body Mass Index (BMI) between 18 and 24 kg/m². Subjects in this group performed a standardized drop jump (DJ) protocol consisting of 100 total jumps from a 60 cm platform. Muscle damage markers (Creatine Kinase and Lactate Dehydrogenase) were measured pre-exercise, immediately post-exercise, and 24 hours post-exercise.

Treatment:

Behavioral: Drop Jump Protocol

Overweight Group

Experimental group

Description:

Participants with a Body Mass Index (BMI) between 25 and 35 kg/m². Subjects in this group performed the same standardized drop jump (DJ) protocol as the normal weight group. Blood samples were collected at three time points to evaluate changes in muscle damage markers (Creatine Kinase and Lactate Dehydrogenase).

Treatment:

Behavioral: Drop Jump Protocol
