摘要

在炎热的环境中踢足球会导致严重的体液不足。如果运动员不能确定他们的失汗量,那么在训练期间和训练之间就不能确定准确的液体摄入需求。本研究评估了大学男足球运动员(n = 17)在高温条件下进行三次90分钟的训练后,汗水损失估计的准确性。数据是在季前赛最后一周的一个早晨收集的(P1;湿球温度(WBGT) = 31.2°C)和同一天下午(P2;WBGT = 26.9°C)实践。第三次评估是在常规赛早晨训练之后进行的(P3;WBGT = 31.5°C)。评估训练前和训练后裸体质量的变化,以及体液摄入和尿量的调整,以确定失汗量。每次练习后,参与者通过在杯子里装满一定量的水来估计他们在练习过程中损失的汗量。三组患者排汗量差异均有统计学意义(p < 0.05) (P1 2.181±0.693;P2 1.706±0.474;P1的预估失汗量小于实际失汗量(P < 0.001)(0.804±0.329 L;40.2±21.5%),p2(0.672±0.324 l;P3(1.076±0.489 L);(31.8±11.6%),但准确率差异无统计学意义。运动员对排汗量的估计与实际排汗量呈上下波动趋势,但运动员一直大大低估了排汗量。对失汗量的可视化描述可能会提高对热环境下足球运动员训练时液体摄入需求的认识。

Collegiate soccer players consistently underestimate practice sweat losses regardless of practice sweat loss volume
Soccer play in hot environments can result in major fluid deficit. If competitors are unsure of their sweat losses, accurate fluid intake needs during and between training bouts cannot be established. This study evaluated sweat loss estimation accuracy among collegiate male soccer players (n = 17) following three, 90-minute practice ses- sions in the heat. Data were collected during the last week of pre-season training during a morning (P1; wet bulb globe temperature (WBGT) = 31.2 °C) and same day afternoon (P2; WBGT = 26.9 °C) practice. The third estimation took place after a regular season morning practice (P3; WBGT = 31.5 °C) the following week. Change in nude body mass, with adjustment for fluid intake and urine output, from pre- to post-practice was assessed to determine sweat loss volume. After each practice participants estimated their sweat loss volume by filling cups with a vol- ume of water equivalent to the volume of sweat they believed they lost during the practice session. Sweat losses differed (p < 0.05) among all 3 practices (P1 2.181 ± 0.693; P2 1.706 ± 0.474; P 3.360 ± 0.956 L). Estimated sweat loss volume was less (p < 0.001) than actual sweat losses for P1 (0.804 ± 0.329 L; 40.2 ± 21.5%), P2 (0.672 ± 0.324 L; 40.1 ± 19.9%) and P3 (1.076 ± 0.489 L; 31.8 ± 11.6%), but there were no differences in percentage accuracy. Players estimations of sweat loss trended up and downward with actual sweat losses, but players greatly and consistently underestimated sweat losses. Visual depiction of sweat loss volume could potentially increase awareness of be- tween training bout fluid intake needs of soccer players training in hot conditions.
