Application of Manual Therapy to Archers
A study testing Manual therapy in people with Healthy, run by Medical University of Gdansk.
Trial summary
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.

About this study
Official title: Assessment of Upper Limb Muscle Activity and the Effect of Manual Therapy on Fatigue, Stiffness and Muscle Activity During Training
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.
Read the detailed description
EMG measurements will be collected for selected muscles in the shoulder joint and forearm, at points: initially at the beginning, after the athletes have performed 50 and another 50 archery shots, and finally after undergoing manual therapy. The main phase of muscle testing will take place in the Aiming phase.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Manual therapyOther
This technique involves a low-amplitude, high-velocity push on the shoulder and elbow joints with an additional two-second tension
PlaceboOther
Performing manipulations without a two-second preliminary tension of the joint capsule in the shoulder and elbow joints.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Each isometric muscle test lasts 3 seconds. The study is performed three times for each muscle.
Muscle stiffness
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
Measured: 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.
