Comparison of Lower Extremity Parameters in Monofin and Bi-fin Swimmers.
Comparison of Lower Extremity Muscle Biomechanical Properties, Joint Range of Motion, and Performance Parameters in Monofin and Bi-fin Swimmers
The purpose of this study is to compare the leg muscle features and joint movements of swimmers who use a single large fin (monofin) versus those who use two fins (bi-fins). Different types of fins change how legs move in the water. This may affect the muscle structure and swimming performance. The researchers want to find out the differences between these two groups of swimmers.
During the study, the researchers will do the following:
Record the age, height, and weight of healthy swimmers who train regularly. Measure the stiffness and flexibility of the leg muscles using MyotonPro device.
Check how well the hips, knees, and ankles can move using digital goniometer.
The findings from this study will help create safer training programs for swimmers. Coaches will use the results to improve swimming performance and lower the risk of leg injuries.

Monofin swimmers

MyotonPro is used to utilize the biomechanical properties of the muscle.
During measurements, the patient will be seated in a chair with back support; the biomechanical properties of the rectus femoris, tibialis anterior, medial gastrocnemius, and hamstring muscles (F - Natural Oscillation Frequency [Hz], Tone or Tension ranges, S - Dynamic Stiffness [N/m], D - Logarithmic Decrease [relative unit], Elasticity increase, R - Mechanical Stress Relaxation Time [ms], C - Relaxation and Deformation Time Ratio [relaxation and deformation time ratio [N/m]) will be measured bilaterally using Myoton PRO.
All measurements will be tracked according to the mileage.
Swimmers' right and left leg lengths (cm) will be measured.
All measurements will be tracked in terms of kilometers covered.
All measurements will be compared statistically according to pallet types.
Passive range of motion of the lower extremity shoulder joint (flexion, extension, adduction, abduction, external rotation, and internal rotation) will be measured using a digital goniometer.
Results will be recorded in degrees (°).
All measurements will be compared statistically according to pallet types.

Measuring the biomechanical properties of muscles with MyotonPro

Bilaterally Biomechanical properties (F - Natural Oscillation Frequency [Hz], characterizing Tone or Tension, S - Dynamic Stiffness [N/m], D - Logarithmic Decrement [relative unit], characterizing Elasticity, R - Mechanical Stress Relaxation Time [ms], C - Ratio of Relaxation and Deformation time [relative unit], characterizing Creep) of the rectus femoris, tibialis anterior, medial gastrocnemius and hamstring muscles were measured using Myoton PRO. Because the MyotonPRO assessment yields a single-session composite outcome by presenting all relevant units concurrently on the screen, these variables were treated as a whole rather than being documented separately. |
