Outcome Measures

Primary Outcomes (1)

  • Muscle Oxygen Saturation Measurement

    Muscle oxygen saturation measurements of the athletes were performed with the MOXY device (Fortiori Design LLC., Minnesota, USA). The MOXY device sends 4 separate near infrared lights and works with a system that goes 12.5-25 mm deep into the skin and gives a numerical average of the amount of light reflected between the sensors. The infrared device, called near infrared spectroscopy (NIRS), measures total hemoglobin, oxygen saturation in capillaries and myoglobin saturation in the muscle. The electrodes are self-adhesive. The device has been shown to be a valid and reliable method for measuring muscle oxygenation (r=0.842-0.993, ICC: r=0.773-0.992). In the athletes in our study, superficial electrodes were placed midline on the quadriceps femoris muscle on the dominant side. Before placement, the electrode sites were shaved and cleaned with alcohol. All measurements were made at the same point and taken in the long sitting position.

    Muscle oxygen saturation measurements were taken before and immediately after training. Subsequently, the measurement was repeated after 15 minutes of passive rest or cold compression and 24 hours later at follow-up.

Secondary Outcomes (2)

  • Fatigue Measurement

    Fatigue measurements of the athletes were taken before and immediately after training. Subsequently, the measurement was repeated after 15 minutes of intervention and at follow-up after 24 hours.

  • Performance Measurement

    The jump heights of the athletes were automatically recorded with the Vert Coach in the training just before the application and in the second training 24 hours later and were included in the evaluation form.

Study Arms (3)

1 Degree Cold Compression Group

Cold compression application was performed using Game Ready for 15 minutes. The target temperature was manually set to 1°C and the pressure was set to high compression (75 mm Hg). Since it is known that the applied pressure increases the effect of cold application and oxygenation in the tissue increases as the compression intensity increases (108), it was applied in the high option. Duration was preferred because the optimal range for the duration of cold applications is given as 11-15 minutes in the literature (120). Pneumatic intermittent compression with a standard ∼3-minute cycle was applied to both lower legs using a thigh wrap. The application was performed with the athletes in the supine semi-recumbent position.

Device: Cold Compression

10 Degree Cold Compression Group

Cold compression application was performed using Game Ready for 15 minutes. The target temperature was manually set to 10°C and the pressure to high compression (75 mm Hg). Pneumatic intermittent compression in a standard ∼3 min cycle was applied to both lower legs using a thigh wrap. The application was performed with the athletes in the supine semi-recumbent position.

Device: Cold Compression

Passive Rest Control Group

The athletes rested passively in the supine semi-recumbent position for 15 minutes after the training.

Interventions

Cold compression was applied to the athletes with the Game Ready (Game Ready; Global, UK) device. The Game Ready (GR) device applies cooling to the tissue by continuous circulation of ice water with intermittent pneumatic compression. The GR consists of a sleeve that surrounds the affected tissue, a tank containing the ice water and a hose connecting the two. There are chambers inside the sleeve and the air pumped through these chambers and the broken ice pieces and water surround the tissue. The pressure settings are no compression (0 mmHg), low compression (5 to 15 mmHg), medium compression (5 to 50 mmHg) and high compression (5 to 75 mmHg). The ice water passes through the sleeve in 3-minute inflation and deflation cycles. The temperature of the water inside the device can be adjusted by adding ice and water. The temperature to be applied to the tissue is set with the screen on the device.
