What They Found
Overall, 41% of the manuscripts used a randomised control trial design with only 1 study being completed on elitelevel athletes competing professionally.
⇒ The most frequent topics covered were carbohydrates, fats, and proteins,
⇒ Each macronutrient was discussed regarding the roles of each with. adaptation, fueling, and recovery from training and competition, particular requirements for athletes and which food sources are best.
⇒ Most of the interventions were delivered face-to-face.
⇒ All in all, this resulted in a nutrition knowledge increase of 19.2 ± 1.6% between before and after interventions.
⇒ A single-arm pre-post design was utilised by 59% (19/32 studies) with the curriculum including hydration, as well as, carbohydrates, fats, and proteins. Similarly, the education was delivered face-to-face and resulted in an average knowledge increase after the intervention of 12.7 ± 0.8%.
⇒ In total, 27/32 studies significantly improved nutrition knowledge in athletes.
