Trainers and athletes have always sought to reduce the failure of muscle function during long endurance events. However, nowadays, it is a topic that is generating much debate in the scientific field. Currently, deep-sea water (DSW) intake seems to be a suitable hydration alternative for this type of endurance event. Therefore, the aim of this study was to determine whether DSW consumption during a triathlon event could preserve muscle function after exercise. Nineteen trained male triathletes (age = 39.0 ± 4.25 years; BMI = 23.67 ± 1.81 kg/m) randomly performed three triathlons, one of them consuming DSW (Totum SPORT 30 AB, Laboratories Quinton International, S.L., Spain), the other consuming isotonic placebo and the last with tap water-hydration. A vertical jump test with countermovement and an isometric muscle strength test were conducted before and after the triathlon test. There was a significant difference between treatment × time during the isometric muscle strength test. Based on the Tukey post hoc analysis, the peak net force decreased statistically in the placebo ( = 0.045) and control conditions ( = 0.026), but not in the experimental condition ( = 0.121). In addition, all of the conditions studied obtained similar results in the countermovement vertical jump after exercise. As a result, consumption of DSW seems to delay the failure of muscle function specifically in isometric exercises but does not improve performance in sports. Thus, DSW does not alter muscle capacity in a negative way; therefore, its consumption may be recommended.
教练和运动员一直试图减少长时间耐力项目中肌肉功能的衰退。然而，如今这一话题在科学领域引发了诸多争论。目前，摄入深海水似乎是这类耐力项目合适的补水方式。因此，本研究的目的是确定在铁人三项比赛中饮用深海水是否能在运动后保持肌肉功能。19名受过训练的男性铁人三项运动员（年龄 = 39.0 ± 4.25岁；体重指数 = 23.67 ± 1.81 kg/m）随机进行三项铁人三项比赛，其中一项饮用深海水（Totum SPORT 30 AB，西班牙昆顿国际实验室），另一项饮用等渗安慰剂，最后一项用自来水补水。在铁人三项测试前后进行了带反向运动的垂直跳跃测试和等长肌肉力量测试。在等长肌肉力量测试中，处理×时间之间存在显著差异。根据图基事后分析，在安慰剂组（P = 0.045）和对照组（P = 0.026）中，峰值净力在统计学上有所下降，但在实验组中没有（P = 0.121）。此外，所有研究条件在运动后的反向运动垂直跳跃中都获得了相似的结果。因此，饮用深海水似乎能特别延缓等长运动中肌肉功能的衰退，但并不能提高运动成绩。因此，深海水不会对肌肉能力产生负面影响；因此，建议饮用深海水。
