Outcome Measures

Primary Outcomes (3)

Trunk muscles activation during forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack
The root mean square of electromyography (EMG) data of bilateral erector spinae and bilateral abdominal external oblique will be normalized by the maximum voluntary contraction amplitude (percentage of maximal voluntary contraction, %)
Immediately during the experiment
Trunk kinematics during forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack
Trunk kinematics, including flexion, extension, lateral flexion and rotation, were measured in degrees (°) across four conditions: forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack.
Immediately during the experiment
Upper limbs muscles activation during forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack
The root mean square of electromyography (EMG) data of the biceps brachii, triceps brachii, anterior deltoid, and pectoralis Major will be normalized by the maximum voluntary contraction amplitude (percentage of maximal voluntary contraction, %) and calculated over forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack.
Immediately during the experiment
