Abstract
PURPOSE: To compare by sex the proportion of college athletes that consume protein below, inside and above the recommended amount. METHODS: We evaluated 341 athletes (192 males and 149 females) from different sports. Food intake was evaluated through a 24-hour reminder for a habitual training day. Afterwards, daily protein intake was estimated and then calculated for g/kg body weight. Afterwards, subjects were categorized into one of three categories according to their daily protein intake: below (<1.4 g/kg/day); inside (1.4 to 2.0 g/kg/day), and above (>2.0 g/kg/day) the recommended amount (as suggested by the International Society of Sports Nutrition). The results were counted and expressed as percentage of subjects at each category. The 95% confidence interval (CI) was calculated for each percentage. This analysis was performed in both male and female athletes and compared by sex RESULTS: The general characteristics of the evaluated subjects for age, weight, height and BMI were 21.2 ± 2.1 y, 74.7 ± 14.1 kg, 176.2 ± 6.9 cm, 24.0 ± 3.8 kg/m2 for males, and 20.6 ± 1.9 y, 61.5 ±11.2 kg, 163.4 ± 6.6 cm, 23.0 ± 3.7 kg/m2 for females, respectively. We observed that the number of male athletes that consumed protein below and inside the recommended amount was the same (61 subjects each; 31.8%, CI 25.2 - 38.5), and the remaining 70 subjects (36.4%, CI 29.5 - 42.3) consumed above the recommended amount of protein. Similarly, the majority of the female athletes consumed above the recommended protein amount (55 subjects; 36.9%, CI 29.1 - 44.7), followed for those who ingested below (53 subjects; 35.6%, CI 27.8 - 43.4) and inside (41 subjects; 27.5%, CI 20.2 - 34.8) the recommended amount. There were no significant differences by sex (p >0.05). CONCLUSIONS: The proportion of athletes consuming protein below, inside and above the recommended amount were similar regardless of sex. Most of the male and female athletes consumed more than 2.0 g/kg/day.
