Since previous studies have reported that elite athletes are often deficient in their nutritional intake (for example, total calories, carbohydrates, protein), a group of researchers decided to evaluate Canadian high-performance athletes. A total ofn= 324 athletes

from eight Canadian sports centers participated in the study. One reported finding was that the average caloric intake among then= 201 women

was 2403.7 kilocalories per day(kcal/d).The recommended amount is2811.5 kcal/d.

For one part of the study,n= 114 male

athletes from eight Canadian sports centers were surveyed. Their average caloric intake was3076.0kilocaloriesper day(kcal/d)with a standard deviation of987.0. The recommended amount is3422.9. Is there evidence that Canadian high-performance male athletes are deficient in their caloric intake?
