Application of Elbow Manipulation in Archers

Analysis of Muscle Strength and Stiffness and the Effect of Manual Therapy on the Time Travel Speed of Kart Drivers

The aim of this study was to: (i) assess the impact of maximal muscle strength and stiffness on EMG and Myoton parameters for selected upper limb muscles; and (ii) assess how manipulation of the initial 2-s tension phase, in particular involving muscle stretching, affects these EMG and Myoton parameters during karting training.

EMG and Myoton measurements will be performed on selected muscles of the shoulder joint and forearm during karting drivers' training, initially at the beginning, after the athletes perform their first 8-minute run, after manipulation and after another 8-minute run.

Inclusion Criteria:

• Healthy persons aged 18,
• A license to drive a kart,
• A competitor who regularly competes in the league,
• Expressing informed consent to participate in the study and undertakes to comply with the regulations on the track and wear a helmet.

Exclusion Criteria:

• Lack of volunteer consent,
• Previous upper, lower limb and spine surgeries,
• Other upper limb injuries in the last 6 months,
• Pain limiting participation in the study,
• Neurological diseases,
• Connective tissue diseases.
