Brief Summary

The mechanical characteristics play a crucial role in sustaining daily life activities and facilitating participation in sport activities and exercises demanding a diverse range of motion. Furthermore, it is postulated that the mechanical composition of the muscle could impact the minimal energy expenditure, perceived exertion, and risk of injury during physical activities. This study aims to examine the effects of various exercise approaches, including aerobic exercise, strength training, and whole-body vibration, on the passive mechanical properties of muscle tissue.

Outcome Measures

Primary Outcomes (4)

• Muscle Strength

  Isokinetic testing and rehabilitation systems were utilized to assess muscle strength. An assessment was conducted on the concentric and eccentric forces exerted on the quadriceps femoris and hamstring muscles in the dominant lower extremity. The assessment of concentric strength was conducted within the knee flexion range of 0-90 degrees, while the evaluation of eccentric strength was undertaken in the knee flexion range of 10-90 degrees at a velocity of 60º/sec. The peak torque values acquired from the experiment were utilized as the basis for the analysis.

  Baseline and at Week 4

• Horizontal Jump

  Test was conducted unilaterally on the dominant lower extremity. Horizontal jump was repeated three times and the average of the measurement results was recorded.

  Baseline and at Week 4

• Muscle Stiffness

  Changes in muscle stiffness were evaluated through shear wave elastography. The alterations in the stiffness properties of the muscle were documented utilizing an ultrasound device. Measurements were conducted on the dominant lower extremity to evaluate alterations in the muscle stiffness of the quadriceps muscles (vastus medialis obliquus, rectus femoris) and hamstring muscles (biceps femoris, semimembranosus).

  Baseline and at Week 4

• Muscle Thickness

  Changes in muscle thickness were evaluated through shear wave elastography. The alterations in the thickness properties of the muscle were documented utilizing an ultrasound device. Measurements were conducted on the dominant lower extremity to evaluate alterations in the muscle thickness of the quadriceps muscles (vastus medialis obliquus, rectus femoris) and hamstring muscles (biceps femoris, semimembranosus).

  Baseline and at Week 4

Study Arms (4)

Whole Body Vibration Exercise

EXPERIMENTAL

Whole body vibration exercises were conducted utilizing a specialized exercise platform. The participants underwent a prescribed exercise protocol involving both static and dynamic exercises on the designated platform. Specifically, static squats at a 30º angle, dynamic deep squats ranging from 30 to 60º, toe raises, weight transfer maneuvers during squats, as well as static and dynamic squat exercises performed unilaterally were implemented as part of the program. Each exercise was performed for 30-50 s with a frequency ranging from 30-45 Hz and an amplitude of 2 mm. The exercise regimen was structured to comprise three sets, with a designated three-minute inter-set rest interval. Physical exercise sessions were conducted on a weekly basis, with a duration ranging from 30 to 45 minutes. The intensity and duration of the exercises were progressively adjusted based on the adherence.

Other: Whole Body Vibration Exercise

Aerobic Exercise

EXPERIMENTAL

Aerobic exercise group were directed to engage in running activity on a conventional treadmill. The participants engaged in aerobic exercise, specifically moderate-to-high-intensity running at 65-80% of their maximal heart rate, for durations of 30-45 minutes per session, three times weekly. Heart rate was monitored with a portable pulse oximetry device.

Other: Aerobic Exercise

Strengthening Exercise

EXPERIMENTAL

Strengthening exercise group, participants engaged in various lower extremity strengthening activities such as straight leg raises, abduction and adduction movements, knee flexion-extension, ankle plantar-dorsiflexion exercises. These exercises were performed both on a bed and in standing positions, utilizing resistance exercise bands.

Other: Strengthening Exercise

Control Group

NO INTERVENTION

The participants continued their daily lives without any exercise practice until the end of the study.
