Abstract/OtherAbstract:
The purpose of this study was to determine the meal and snack eating frequency and the nutritional composition of each eating occasion of Canadian high performance athletes during training. Athletes from 8 Canadian Sport Centres prospectively completed 3-day dietary records, including all food, fluid and supplements consumed. The time of consumption and if the consumption was a meal or snack were also identified. The dietary records were analyzed for energy (kcal) and macronutrient intake (CHO, protein, fat) and compared based on gender, age, meal versus snack and training versus rest days. Three hundred and twenty-four athletic subjects (64% females and 36% males) completed the study. On average the athletes ate 4.8 ± 0.8 times daily. Nearly all athletes consumed three daily meals of breakfast (98.9%), lunch (97.9%) and dinner (98.7%) with less having snacks: 57%, 71.6% and 58.1% of athletes consumed an AM, PM and evening snack, respectively. Training day meal frequency did not differ from that during rest days, however, fewer snacks were consumed on rest days. AM and PM snacks were consumed significantly more often on training days than rest days. Overall snacks contributed 24.3% of total daily energy intake. Few dietary variations were discovered between genders, while the youngest athletes (< 18 yrs) ate less often, especially their morning snack, compared to the older athletes. In conclusion: Canadian high performance athletes self-adjusted their energy intakes on training versus rest days primarily by snacking less and reducing their carbohydrate and protein intakes on rest days yet they consistently ate regular meals.
