Athletes participating in the athletics (track and field) events of jumps, throws and combined events (CE; 7-event heptathlon, 10-event decathlon) engage in training and competition that emphasizes speed and explosive movements, requiring optimal power-to-weight ratios. While these athletes represent a wide range of somatotypes, they share an emphasis on type IIa and type IIx muscle fiber-typing. In general, athletes competing in jumps tend to have a lower body mass (BM) and may benefit from a higher protein (1.5-1.8 g PRO/kg/day), lower carbohydrate diet (3-6 g CHO/kg/day). Throwers tend to have a higher BM, but with considerable differences between events. Their intense, whole-body training program suggests higher protein requirements (1.5-2.2 g PRO/kg/day), while carbohydrate needs (per kg) are similar to jumpers. CE athletes must strike a balance between strength and muscle mass for throws and sprints, while maintaining a low enough BM to maximize performance in jumps and middle-distance events. CE athletes may benefit from a higher (1.5-2 g PRO/kg/day) protein, moderate carbohydrate (5-8 g CHO/kg/day) diet with good energy availability to support multiple daily training sessions. Since they compete over two days, well-rehearsed competition-day fueling and recovery strategies are imperative for CE athletes. Depending on their events' bioenergetic demands, athletes in throws, jumps, and CE may benefit from the periodized use of ergogenic aids, including creatine, caffeine, and/or beta-alanine. The diverse training demands, physiques, competitive environments of jumpers, throwers, and CE athletes necessitates nutrition interventions that are periodized throughout the season, and tailored to the individual needs of the athlete.
