Please help in solving this problem, as I'm not sure how to correctly answer this. It is recommended that athletes consume 1.0-2.0 grams of protein/kg body weight per day, depending upon level and type of activity. Additionally, women who are pregnant or lactating have additional protein needs. The amount of additional protein intake is listed below. General recommendations for Athletes: - Sedentary DRI is 0.8 g/kg/day. - General guideline for athletes: 1.0-2.0 g/kg/day. - Guideline for recreational athletes: 0.8-1.0 g/kg/day. - Guideline for strength athletes: 1.2-1.7 g/kg/day. - Guideline for endurance athletes: 1.2-1.4 g/kg/day. - Guideline for ultra-endurance athletes: 1.2-2.0 g/kg/day. Women Extra Need: - Pregnant: Add ten grams to prepregnant recommendation. - Lactating: Add 15 grams (first six months) and 12 grams thereafter. (20 pts) For the athletes below, determine an appropriate amount of protein intake. As the general recommendations are given as a range, briefly explain which end of the range you would recommend based on the athlete's activity or goals. Calculations are needed to get any credit. Explain the rationale for the lower or upper end of the range recommendation. Protein needed (daily):
  1. Recreational 152-pound male athlete playing volleyball three times per week.
  2. Bodybuilder 216 pounds training to increase skeletal muscle mass.
  3. 10 km female runner 112 pounds maintaining body composition.
  4. Female triathlete 125 pounds in a high-volume training period.
