The purpose of this investigation was to determine the influence of intermittent neck cooling during exercise bouts designed to mimic combat sport competitions. Participants ( = 13, age = 25.3 ± 5.0 year height = 176.9 ± 7.5 cm, mass = 79.3 ± 9.0 kg, body fat = 11.8% ± 3.1%) performed three trials on a cycle ergometer. Each trial consisted of two, 5-min high-intensity exercise (HEX) intervals (HEX1 and HEX2-20 s at 50% peak power, followed by 15 s of rest), and a time to exhaustion (TTE) test. One-minute rest intervals were given between each round (RI1 and RI2), during which researchers treated the participant's posterior neck with either (1) wet-ice (ICE); (2) menthol spray (SPRAY); or (3) no treatment (CON). Neck (T) and chest (T) skin temperatures were significantly lower following RI1 with ICE (vs. SPRAY). Thermal sensation decreased with ICE compared to CON following RI1, RI2, TTE, and a 2-min recovery. Rating of perceived exertion was also lower with ICE following HEX2 (vs. CON) and after RI2 (vs. SPRAY). Treatment did not influence TTE (68.9 ± 18.9s). The ability of intermittent ICE to attenuate neck and chest skin temperature rises during the initial HEX stages likely explains why participants felt cooler and less exerted during equivalent HEX bouts. These data suggest intermittent ICE improves perceptual stress during short, repeated bouts of vigorous exercise.
本研究的目的是确定在模拟格斗运动比赛的运动过程中进行间歇性颈部冷却的影响。参与者（n = 13，年龄 = 25.3 ± 5.0岁，身高 = 176.9 ± 7.5厘米，体重 = 79.3 ± 9.0千克，体脂 = 11.8% ± 3.1%）在功率自行车上进行了三次试验。每次试验包括两个5分钟的高强度运动（HEX）间歇（HEX1和HEX2——以50%峰值功率持续20秒，随后休息15秒），以及一次疲劳时间（TTE）测试。每轮之间给予1分钟的休息间歇（RI1和RI2），在此期间，研究人员对参与者的后颈部进行以下处理之一：（1）湿冰（ICE）；（2）薄荷喷雾（SPRAY）；或（3）不进行处理（CON）。使用ICE处理后，RI1后的颈部（T）和胸部（T）皮肤温度显著低于使用SPRAY处理后（与SPRAY相比）。与CON相比，在RI1、RI2、TTE和2分钟恢复后，使用ICE处理时热感觉降低。在HEX2后（与CON相比）和RI2后（与SPRAY相比），使用ICE处理时的主观用力感觉评分也较低。处理对TTE没有影响（68.9 ± 18.9秒）。间歇性ICE在初始HEX阶段减弱颈部和胸部皮肤温度升高的能力，可能解释了为什么参与者在同等的HEX回合中感觉更凉爽、用力更小。这些数据表明，间歇性ICE可改善短时间、重复的剧烈运动过程中的感知压力。
