About this trial
The aim of this study is to: (i) characterize the effect of repeated archery shots on the EMG parameters of certain selected upper limb muscles; and (ii) evaluate how manipulation of the initial two-second tension phase, in particular involving muscle stretching, affects these EMG parameters after repeated shots.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Actively training as an archer at least twice a week for six months;

Over 18 years of age;
Engagement in all phases of the study.
Disqualifiers
Any injury or illness present at the time of the study;
Recent history (within six months) of upper extremity injury (shoulder, elbow, or wrist), joint pain, lower extremity joint hypermobility, or neurological/connective tissue disease.
No training participation
No consent for study

Treatments tested in this trial
Manual therapy
Other interventionThis technique involves a low-amplitude, high-velocity push on the shoulder and elbow joints with an additional two-second tension
Placebo
Other interventionPerforming manipulations without a two-second preliminary tension of the joint capsule in the shoulder and elbow joints.

Trial outcomes
Primary outcomes
1
Assessment of MVC.
Muscle EMG is an assessment of the electrical characteristics during the study, the electrical source of which is the muscle membrane potential, and the measured EMG potentials are measured in μV and the repetition rate of muscle motor unit firing measured in Hz, at the same time of the study.
Time frame
Each isometric muscle test lasts 3 seconds. The study is performed three times for each muscle.2
Muscle stiffness
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
Time frame
Each Myoton application lasts 1 sec for one point. Three evaluations of one of the two points for one muscle are performed. It is assumed that the study with recording will last 30 seconds for one muscle.Locations
