Abstract:
(1) Background: 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. (2) Methods: Nineteen trained male triathletes (age = 39.0 ± 4.25 years; BMI = 23.67 ± 1.81 kg/m2) 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. (3) Results: 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 (p = 0.045) and control conditions (p = 0.026), but not in the experimental condition (p = 0.121). In addition, all of the conditions studied obtained similar results in the countermovement vertical jump after exercise. (4) Conclusions: 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.
摘要:
(1)背景:训练师和运动员一直在寻求减少长期耐力比赛中肌肉功能的衰竭。然而,如今,这是一个在科学领域引起很多争论的话题。目前,深海水(DSW)的摄入量似乎是这种耐力比赛的合适补水替代品。因此,这项研究的目的是确定在三项全能比赛期间消耗DSW是否可以在运动后保持肌肉功能.(2)方法:19名受过训练的男子铁人三项运动员(年龄=39.0±4.25岁;BMI=23.67±1.81kg/m2)随机进行三项铁人三项,其中一个消费DSW(Totum运动30AB,昆顿国际实验室,S.L.,西班牙),另一种是服用等渗安慰剂,最后一种是用自来水水合。在铁人三项测试之前和之后进行了带有反向运动的垂直跳跃测试和等距肌肉力量测试。(3)结果:在等距肌力测试期间,治疗×时间之间存在显着差异。根据Tukey事后分析,峰值净力在安慰剂(p=0.045)和对照条件(p=0.026)中统计学下降,但不是在实验条件下(p=0.121)。此外,所有研究的条件在运动后的反运动垂直跳跃中获得了相似的结果。(4)结论:因此,消耗DSW似乎可以延迟肌肉功能的衰竭,特别是在等距运动中,但不能改善运动表现。因此,DSW不会以负面方式改变肌肉容量;因此,它的消费可以推荐。
