About this study
Official title: 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.
Read the detailed description
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.

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 electrical characteristics during the test, the electrical source of which is the muscle membrane potential, and measured in μV.
Measured: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2). Each isometric muscle test lasts 3 seconds.
2 Assessment of MVC.
Muscle EMG is an assessment of electrical characteristics during the test, which is measured by the repetition frequency of muscle motor unit discharges, which is measured in Hz, at the same time of the test.
Measured: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2).Each isometric muscle test lasts 3 seconds.
3. Muscle stiffness
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
Measured: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2). Each Myoton application lasts 1 sec for one point.

What does the primary outcome measure?
Assessment of MVC. (time frame: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2). Each isometric muscle test lasts 3 seconds.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
