This study was conducted to investigate the effect of kinesio tapping on electrical activity and peak torque of quadriceps during concentric and eccentric muscle contraction were carried out in the motion analysis Laboratory.

A Pretest posttest control group design was used to. Two hundred normal subjects of both sexes were recruited.

Subjects were randomly assigned into two groups of equal number.

• Cura Kensio-tapping group: consisted of 100 subjects (females and males) will receive kinesio taping from origin to insertion on the superficial muscles of Quadriceps femoris (vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF).
• Placebo-Group: consisted of 100 subjects (females and males) will receive placebo kinesio taping across quadriceps.

Inclusion Criteria:

• Age must be ranged from 22-30 years.
• Body mass index must be ranged from 20-24.9 kg/m².

Exclusion Criteria:

• Knee or quadriceps disorders preventing physical stress.
• Cardiovascular or neurological problems.
• Athletic subjects.
• Smokers.
• Heavy caffeine intake subjects.
