Objective

The present study aimed to examine the acute effects of legal-market cannabis on regular cannabis users’ subjective responses to exercise in a controlled laboratory environment.

Background

Given the stereotype that cannabis is associated with extreme sedentary behavior, there are concerns that cannabis legalization may exacerbate the US physical inactivity epidemic. However, despite these concerns, recent years have seen considerable public interest in the use of cannabis concurrently with exercise (e.g., running).

Methods

The present study compared participants’ experiences of exercise without cannabis to their experiences of exercise after acute ad libitum use of one of two commercially available cannabis flower products: a Δ9-tetrahydrocannabinol-dominant or a cannabidiol-dominant product. Participants (N = 42) were regular cannabis users between the ages of 21 and 39 years (mean = 30.81 years, standard deviation = 4.72 years).

Results

Although participants reported a more positive affect (p < 0.001), enjoyment (p < 0.001), and runner’s high symptoms (p < 0.001) during their cannabis (vs non-cannabis) exercise appointment, they also reported more exertion (p = 0.04). Pain levels were very low and did not differ between appointments (p = 0.45). Effects appeared to depend, in part, on cannabinoid content; there was a larger difference in enjoyment (p = 0.02), and a smaller difference in exertion (p = 0.02), between the cannabis and non-cannabis exercise appointments among participants in the cannabidiol (vs Δ9-tetrahydrocannabinol) condition.

Conclusions

To our knowledge, this is the first study to investigate the acute effects of commercially available cannabis on subjective responses to exercise in a laboratory environment. Our findings suggest that, among regular cannabis users who use cannabis in combination with exercise, cannabis use prior to exercise may lead to increases in both positive and negative aspects of the subjective exercise experience. Research using diverse samples, exercise modalities, and methodologies (e.g., placebo-controlled trials) is needed to establish the generalizability of these findings.

随意使用市售大麻产品对有氧运动主观体验的急性影响：一项交叉研究

客观的

本研究旨在研究合法市场大麻对常规大麻使用者在受控实验室环境中运动的主观反应的严重影响。

背景

鉴于大麻​​与极端久坐行为有关的刻板印象，有人担心大麻合法化可能会加剧美国缺乏身体活动的流行。然而，尽管存在这些担忧，近年来公众对在运动（例如跑步）的同时使用大麻产生了相当大的兴趣。

方法

本研究将参与者在没有大麻的情况下的运动经历与他们在急性随意使用两种市售大麻花产品之一（以 Δ9-四氢大麻酚为主或以大麻二酚为主的产品）后的运动经历进行了比较。参与者 ( N  = 42) 是年龄在 21 至 39 岁之间的经常吸食大麻的人（平均 = 30.81 岁，标准差 = 4.72 岁）。

结果

尽管参与者在大麻（与非大麻）运动预约期间报告了更积极的情绪 ( p  < 0.001)、享受 ( p  < 0.001) 和跑步者的高症状 ( p  < 0.001)，但他们也报告了更多的运动 ( p  = 0.04) ）。疼痛水平非常低，并且在两次预约之间没有差异（p  = 0.45）。效果似乎部分取决于大麻素含量； 大麻二酚（与 Δ9-四氢大麻酚）条件下的参与者在大麻和非大麻运动预约之间存在较大的享受差异（p  = 0.02）和较小的运动差异（p = 0.02）。

结论

据我们所知，这是第一项调查商业大麻对实验室环境中运动主观反应的急性影响的研究。我们的研究结果表明，在使用大麻与运动相结合的常规大麻使用者中，运动前使用大麻可能会导致主观运动体验的积极和消极方面增加。需要使用不同的样本、运动方式和方法（例如安慰剂对照试验）进行研究，以确定这些发现的普遍性。
