• 1 other identifier: KB/750/2023-2024
• Study Type: interventional
• Target: 50

• Sites: N/A

Brief 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.

Conditions

Healthy

Keywords

archery; muscle fatigue; recovery; manipulation

Outcome Measures

Primary Outcomes (2)

• 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.

  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.

  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.

Study Arms (1)

Assessment of acute effects of manipulation and muscle strength

ACTIVE COMPARATOR

Performing the manipulation with a preliminary two-second tension of the joint capsule in the shoulder and elbow joints.

Other: Manual therapy; Other: Placebo

Interventions

Manual therapy OTHER

This technique involves a low-amplitude, high-velocity push on the shoulder and elbow joints with an additional two-second tension

Assessment of acute effects of manipulation and muscle strength

Placebo OTHER

Performing manipulations without a two-second preliminary tension of the joint capsule in the shoulder and elbow joints.
