巧克力香气助力男性完成更多抗阻训练

一项发表在《Frontiers in Physiology》的研究发现，在抗阻训练前和训练中闻巧克力香气能够帮助参与者完成更多次数的腿部伸展运动，且不会增加疲劳感1。这项研究由马来亚大学运动与运动科学学院进行，参与者为23名20多岁早中期的健康男性，训练水平均为中等1。

在香气类型的对比中，深色巧克力（可可含量90%）产生了最强效果，相比对照组（水）使参与者增加约18次重复次数，而牛奶巧克力（可可含量60%）则增加约9次重复次数1。除了训练表现的提升外，深色巧克力还显著降低了参与者的饥饿感和食欲1。相比之下，牛奶巧克力虽然被评为更令人愉悦，但未能显著改变参与者的饥饿感或食欲1。

研究人员认为这一现象可能与学习关联和大脑对食物摄入的预期有关1。实验中，参与者在禁食至少10小时后进行测试1。

A study published in Frontiers in Physiology has found that smelling chocolate before and during resistance training enabled participants to complete additional leg extension repetitions without experiencing greater fatigue 1. The research involved 23 healthy men in their early to mid-twenties with moderate training experience who were tested after fasting for at least 10 hours 1.

The strength of the effect varied by chocolate type 1. Dark chocolate with 90% cocoa content produced the most pronounced results, increasing the number of leg extension repetitions by approximately 18, while milk chocolate containing 60% cocoa increased repetitions by around 9 1. Researchers attributed this effect to learned associations and the brain's anticipatory response to food intake 1. When compared to a water control, dark chocolate significantly reduced both hunger sensations and appetite, whereas milk chocolate, though rated as more pleasant by participants, did not produce significant changes in hunger or appetite 1.

The research was led by Mohamed Nashrudin bin Naharudin, an assistant professor at the Faculty of Sports and Exercise Science at the University of Malaya 1, and was published on September 15, 2026 1.
