  1. Protein Intake in Volleyball Players

  2. Introduction • Recommendations for endurance athletes is 1.2-1.4g/kg • Growing female athletes need to be sure it is met • Is overall caloric intake representative of protein intake? • “ Protein metabolism during and after exercise is affect by sex, age, intensity, duration, and type of exercise, energy intake… Protein intake for adults older than 18 is 10-15% of total calories.” ASCM

  3. The impact of feedback on dietary intake and body composition of college women volleyball players over a competitive season. • Dietary intake from 15 NCAA volleyball players over the course of two seasons. • First season received no feedback, second did. • Players were consuming les than, or just at the recommended protein intake (1.2g/kg-1.4g/kg) in first season. • After feedback, player’s overall energy intake dropped; protein mostly stayed the same.

  4. Eating Behaviors, Nutritional Status, and Menstrual Function in Elite Female Adolescent Volleyball Players • 23 nationally ranked volleyball players surveyed. • 12 fell short of the protein recommendation (1.2-2.0). • 10 fell short of recommended energy intake. • 52% felt pressure to lose weight, or maintain low body weight.

  5. Macro- and micro-nutrient intake of adolescent Greek female volleyball players. • 65 adolescent Greek volleyball players were surveyed. • All players met the recommendations for protein given in the study (1.0g/kg-1.2g/kg), but not adequate amounts according to the ACSM recommendations. • Protein recommendations for this study were set lower than in previous two studies.

  6. Conclusion • Evidence overwhelmingly indicates adequate nutrient intake is essential for optimal performance. • Many volleyball players not consuming enough protein • Recommended solution is to supplement with protein powder or bar. • “Recommending protein intakes in excess of the RDA to maintain optimal physical performance is commonly done in practice.” ACSM • With education, athletes can achieve adequate protein and energy intake from food, reducing change of overconsumption.
