Rugby is characterized by frequent high-intensity collisions, resulting in muscle soreness. Players consequently seek strategies to reduce soreness and accelerate recovery, with an emerging method being cannabidiol (CBD), despite anti-doping risks. The prevalence and rationale for CBD use in rugby has not been explored; therefore, we recruited professional male players to complete a survey on CBD. Goodness of fit chi-square (χ2) was used to assess CBD use between codes and player position. Effects of age on use were determined using χ2 tests of independence. Twenty-five teams provided 517 player responses. While the majority of players had never used CBD (p < .001, V = 0.24), 26% had either used it (18%) or were still using it (8%). Significantly more CBD use was observed in rugby union compared with rugby league (p = .004, V = 0.13), but player position was not a factor (p = .760, V = 0.013). CBD use increased with players' age (p < .001, V = 0.28), with mean use reaching 41% in the players aged 28 years and older category (p < .0001). The players using CBD primarily used the Internet (73%) or another teammate (61%) to obtain information, with only 16% consulting a nutritionist. The main reasons for CBD use were improving recovery/pain (80%) and sleep (78%), with 68% of players reporting a perceived benefit. These data highlight the need for immediate education on the risks of CBD, as well as the need to explore the claims regarding pain and sleep.
橄榄球的特点是频繁的高强度碰撞,导致肌肉酸痛。因此,球员们寻求减少酸痛和加速恢复的策略,其中一种新兴方法是大麻二酚(CBD),尽管存在兴奋剂风险。在橄榄球中,CBD 的使用频率和原理尚未得到探索;因此,我们招募了专业的男性球员来完成一项关于 CBD 的调查。拟合优度卡方(χ2)用于评估不同比赛项目和球员位置之间 CBD 的使用情况。使用独立性 χ2 检验来确定年龄对 CBD 使用的影响。25 支球队提供了 517 名球员的回复。尽管大多数球员从未使用过 CBD(p <.001,V = 0.24),但 26%的球员要么使用过(18%),要么仍在使用(8%)。与橄榄球联盟相比,橄榄球联合会中 CBD 的使用明显更多(p =.004,V = 0.13),但球员位置不是一个因素(p =.760,V = 0.013)。随着球员年龄的增长,CBD 的使用量增加(p <.001,V = 0.28),年龄在 28 岁及以上的球员中,CBD 的使用率达到 41%(p <.0001)。使用 CBD 的球员主要通过互联网(73%)或另一名队友(61%)获取信息,只有 16%的球员咨询营养师。使用 CBD 的主要原因是改善恢复/疼痛(80%)和睡眠(78%),68%的球员报告称 CBD 有一定效果。这些数据突出表明,需要立即对 CBD 的风险进行教育,同时需要探索关于疼痛和睡眠的说法。
