Acute Effects of Heat, Cold and Stretching on Knee Proprioception and Vertical Jump

The aim of our study is to investigate the effects of heat, cold and stretching on knee proprioception and vertical jump. 60 healthy individuals were randomized into hot, cold, stretching and control groups of 15 each. Pre-test and post-test measurements were made immediately after the application. Knee proprioception was measured with a digital goniometer using the EPD (joint position sense) test. Vertical jump heights were measured with contact mat by countermovement (CMJ) and squat splash (SQS) tests.

Treatment and study plan

Stretching

Other

Static stretching technique was applied to the quadriceps and hamstring muscle groups in both the dominant and non-dominant extremities of the participants in the stretching group. All stretches were performed twice for 20 seconds with a 3-second rest.

Hot pack application

Other

Hot pack application was applied to the participants in the hot group to warm the extremities locally after the pre-tests were completed. For the application of hotpack, which is a superficial and moist temperature agent, a Chattanooga ® brand hotpack pad (DJO Global, Chattanooga; CA, USA) with 10 slices and a size of 28 cm x 39 cm was used. The hotpack pad was taken with the help of tongs from the Chattanooga ® brand hot pack boiler (DJO Global, Chattanooga; CA, USA) at 80° temperature and wrapped in a total of 5 layers with the help of 2 towels. A hotpackpad was placed on each knee of the participant. Hotpack pads were applied for 15 minutes in total.

Cold pack application

Other

For participants in the cold group, MSD ® brand cold pack gel (MVS Inmotion, MSD cold pack; Weftdijk 1502830, Belgium), 15 cm x 25 cm in size, was used to cool the extremities locally. The cold pack gel, kept in the freezer, was wrapped in a paper towel and placed on the knee area. Cold pack was applied to both knees for a total of 15 minutes.

Primary outcomes

  1. Vertical Jump Distance Measurement

    Time frame: Before and immediately after application

    Two types of vertical jump distances, squat jump and countermovement jump, were evaluated using a Fusion Sport ® brand jump meter (Fusion Sport, SmartJump; Colorado, USA) with a sensitivity of 1 nanometer, which is one thousandth of an antimeter. Both tests were repeated a total of 3 times and the best results were recorded.

  2. Joint Position Sense Measurement

    Time frame: Before and immediately after application

    For the active joint position sense test, which measures the individual's ability to find the taught target angle, a BASELINE ® brand digital goniometer (BASELINE ® Evaluation Instruments, Digital Absolute + Axis goniometer; NY, USA) with a sensitivity of 0.1° was used.
