Elite athletes face relentless competition schedules that push their bodies to the limit. Effective recovery after intense efforts is essential for sustaining peak performance, and researchers are exploring innovative strategies to optimize it. The focus is on combating exercise-induced fatigue, which includes pain, tissue inflammation, and muscle weakness.
Cannabis sativa (cultivated hemp) contains numerous bioactive compounds, including at least 144 cannabinoids. The most researched are Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Unlike THC, CBD is non-psychoactive. First isolated in 1940, it gained medical attention for its anticonvulsant properties, particularly in treating two rare, severe forms of epilepsy resistant to standard therapies. In 2018, the U.S. Food and Drug Administration approved the first CBD-based drug, Epidiolex, for these conditions.
As studies advanced, additional therapeutic benefits emerged, leading to diverse CBD products like oils, capsules, patches, sprays, and topical creams. CBD flowers are also available for vaporizing or brewing as tea. Note: A French decree published in the Official Journal on December 31 banned CBD flowers and leaves, but the Council of State suspended enforcement on January 24.
In recent years, CBD products have proliferated across France, meeting rising consumer demand for their calming effects. Clinical trials indicate CBD may reduce anxiety, combat insomnia, and alleviate chronic pain through analgesic properties—though larger, long-term studies are needed to confirm efficacy and safety.
More compelling for athletes, emerging evidence suggests CBD enhances recovery. Natural aids like ginseng, green tea, curcumin, and beetroot have proven anti-inflammatory, antioxidant, and pain-relieving effects post-exercise. CBD joins this lineup of beneficial botanicals.
Preliminary research highlights CBD's physiological, biochemical, and psychological benefits for athletes—without cannabis's psychoactive effects. Its popularity has surged since the World Anti-Doping Agency (WADA) removed CBD from its prohibited list in 2018.
A 2023 narrative review in Frontiers in Physiology found one-third of cyclists, triathletes, and runners have used cannabinoids (THC + CBD). In rugby, 28% report usage, rising with age, citing pain relief and better sleep as key advantages.
A 2019 study linked CBD's effects on physiology and cognition to the endocannabinoid system (ECS), which maintains bodily homeostasis and mediates exercise-induced well-being, happiness, and euphoria. Cannabinoids activate CB1 and CB2 receptors, mimicking exercise's appetite suppression, anti-inflammatory, and anxiolytic effects.
To assess cardiovascular risks, a 2020 study in the International Journal of Molecular Sciences tested CBD on healthy animals and volunteers, finding no harmful effects. Researchers noted: "Although CBD shows vasodilatory and antioxidant properties in hypertension, it did not alter blood pressure in hypertensive models. Its hypotensive effects appear primarily under stress." They added: "Many positive effects of CBD have been observed in experimental models of heart disease."
While promising, CBD remains an experimental recovery tool for elite athletes due to limited high-level studies. The Frontiers in Physiology review urges more research in sports populations. Still, initial findings support its role in streamlining recovery, managing pain, and even combating opioid dependency.
