简要总结
The aims of this study are to investigate the effects of scapular muscle fatigue on scapular joint position sense and neuromuscular performance (scapular muscle strength, the kinematics data and muscle activity of shoulder during scaption (arm elevation in the scapular plane)). The investigators hypothesize that scapular muscle fatigue would increase scapular reposition error and affect neuromuscular performance of the scapular during scaption.

结局指标
主要结局
Change From Baseline in Scapular Proprioception
时间窗: through fatigue intervention completion, an average of 20 minutes in female subjects and 40 minutes in male subjects
Test the ability of active re-position the scapula from neutral to 90% range of protraction, and elevation.
Change From Baseline in Muscle Activation During Scapular Proprioception
时间窗: through fatigue intervention completion, an average of 20 minutes in female subjects and 40 minutes in male subjects
Test the ability of muscle activation (upper trapezius, lower trapezius, and serratus anterior) during active re-position the scapula from neutral to 90% range of protraction, and elevation. Muscle activation during active re-position would divide into muscle activation during maximum voluntary isometric contraction (MVIC), present in percent.

- Change From Baseline in Shoulder Kinematics Data During Shoulder Elevation in the Scapular Plane(through fatigue intervention completion, an average of 20 minutes in female subjects and 40 minutes in male subjects)
- Change From Baseline in Scapular Muscle Activity During Shoulder Elevation in the Scapular Plane(through fatigue intervention completion, an average of 20 minutes in female subjects and 40 minutes in male subjects)
- Change From Baseline in Scapular Muscle Recruitment Timing During Arm Elevation in Scapular Plane(through fatigue intervention completion, an average of 20 minutes in female subjects and 40 minutes in male subjects)
