Electromyographic Analysis And Body Balance In The Use Of Athletes After Cryotherapy By Immersion Ankle

The influence of cryotherapy on ankle motor control and balance of athletes is controversial. The aim of this study is to assess the neuromuscular response of the dominant leg and body balance basketball athletes after application of cryotherapy. The sample is distributed into two groups. Group one will consist of 20 basketball players without a history of ankle sprains in the past 12 months and no complaints of instability in this joint, and group two, 20 non-athletes, active, no complaints in the lower limb in the last 12 months. Will perform the inversion movements and single-leg hop for the analysis of the electromyographic signal of anterior tibial, peroneal, gastrocnemius (lateral), rectus femoris, hamstrings and gluteus medius. Will also be performed kinematic analysis in search of body balance and range of motion of the joints of the lower limbs. And yet, the analysis of the plantar support and ground reaction force. After the initial collection of the data subjects will be submitted to the application of cryotherapy by immersion in a time of 20 minutes, with a temperature of 6 ± 2 degrees Celsius. Data collection will be held in pre, 0, 10, 20 and 30 minutes after application of cryotherapy. The data will be statistically analyzed to compare the results in collection times within and between groups. The significance level is set at 5%. The data support the intended use of cryotherapy in motor control of the inversion movement, jump and balance of athletes.

About this study

Forty male subjects, aged 21.6 (±3.2) yr, 177.9 (±7.9) cm tall, 82.8 (±19.3) Kg body weight and 25.9 (±4.8) Kg.m-2 body mass index (BMI) were evaluated. Skin surface temperature before and after cold-water immersion was 27.7(±3)°C and 7.1 (±1)°C, respectively (p=0,0001).

Treatment and study plan

cryotherapy by immersion

Other

the dominant leg was immersed in cold water for 20 minutes [2, 17], temperature of 4º C [22, 24], water level at 20 cm

Other names: Cryoimmersion, 20 minutes, temperature was 4C.

Primary outcomes

  1. Cryoimmersion decreases neuromuscular response of lower limb after ankle inversion

    Time frame: 2 years

    The peak values of the electromyographic signal amplitude (RMS) were obtained from thirty-five healthy, active university subjects after the use of a tilt platform to force the ankle into a 30º of inversion before (pre), and immediately after (post) 10, 20, and 30 minutes, followed by cold-water immersion at 4ºC, for 20 minutes. Shapiro-Wilk test, Repeated Measure Analysis and Bonferroni post-hoc test provided the results. Peak RMS values were significantly lower at all times after cold-water immersion when compared to prior application for all muscles, except in the post-immediate time for GM. There was a decrease in muscular response to the ankle inversion movement after cooling, with residual effect of up to 30 minutes. Therefore, special care should be taken by those involved in sports activities.
