Summary

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.

Conditions

• Body Mass Index
• Physical Exertion
• Muscle Damage
• Creatine Kinase
• Lactate Dehydrogenases

Interventions

Type	Name	Description
BEHAVIORAL	Drop Jump Protocol	A standardized drop jump (DJ) protocol involving 100 total jumps from a 60 cm platform. Participants performed five sets of 20 jumps, with a 10-second rest between jumps and a 2-minute rest between sets. The protocol was designed to induce muscle damage through eccentric loading.
