BACKGROUND Cryotherapy has been associated with a significant decrease in nerve conduction velocity and muscle contraction with possible effects on exercise and physical training. OBJECTIVES To quantify the electromyographic response of the lateral gastrocnemius, tibialis anterior, fibularis longus, rectus femoris and gluteus medius to ankle inversion following cold water immersion. METHOD ...

To improve the conventional cold water immersion test for assessing peripheral circulatory function, the immersed area of the hand was changed in this study. Twenty-seven healthy medical students with a mean age of 24 years participated in the study. The cold water immersion tests were carried out using two methods (in 5 degree C water for 1 min), in which the immersed area was up to the metaca...

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s= 2.1; height 1.84 m, s= 0.34; body mass 88.5 kg, s= 14.7) were assigned to one of three treatment groups: carbohydrate+stretching (7.7 g kg(-1) day(-1), s= 1.7; 'n = 9), cold water immersion (11 degrees C, 5 x 1; n = 10) or ...

Cold thermoregulatory models (CTM) have primarily been developed to predict core temperature (T(core)) responses during sedentary immersion. Few studies have examined their efficacy to predict T(core) during exercise cold exposure. The purpose of this study was to compare observed T(core) responses during exercise in cold water with the predicted T(core) from a three-cylinder (3-CTM) and a six-...

Cold-induced vasodilatation (CIVD), which occurs in fingers and toes exposed to extreme cold, is a defensive reaction of protecting the extremities against frostbite. Yoshimura and Iida (1950) developed a practical method, based on observation of CIVD reactivity, for assessing peripheral resistance against frostbite (local cold tolerance). Thereafter, many studies using this test method to clar...

Trauma-induced cold intolerance (cold sensitivity) is characterised by pain, stiffness, altered sensibility, or colour change associated with cold exposure (Campbell and Kay 1998), and is common after nerve injury or surgery (Irwin et al 1997). The Immersion in Cold water Evaluation (ICE) is a cold stress test administered through a standardised protocol where the hand is immersed in cold water...

Newborn Holstein-Friesian calves were cold stressed by immersion in water at 15 to 17 degrees C until the core body temperature was lowered by 10 degrees C. Non-cold stressed calves were immersed in water at thermoneutral temperature (35 to 37 degrees C). The time required to lower the core body temperature of the cold stressed calves by 10 degrees C was 172 +/- 87 minutes (mean +/- SD). The ti...
