Bodybuilders reduce dietary variety when preparing for competition, consuming fewer food items and less variety among food groups. Despite this, their precompetition diets remain nutrient-dense, except for calcium and zinc.

Area of Science:

  • Sports Nutrition
  • Dietary Habits
  • Nutritional Science

Background:

  • Bodybuilders undergo specific dietary regimens to optimize physique for competition.
  • Understanding dietary changes during contest preparation is crucial for athlete health and performance.

Purpose of the Study:

  • To analyze and describe the food selection patterns of male and female bodybuilders during the precompetition phase.
  • To compare dietary variety and nutrient intake between noncompetition and precompetition periods.

Main Methods:

  • Utilized 3-day food records from male (n=7) and female (n=12) bodybuilders.
  • Collected noncompetition data 6-17 weeks prior and precompetition data 3 days before competition.
  • Classified foods using the Exchange System and additional categories (desserts, beverages).

Main Results:

  • Noncompetition diets featured greater numbers of different food items and overall variety compared to precompetition diets.
  • Precompetition diets showed reduced variety within food groups and across the diet.
  • Despite reduced variety, precompetition diets exhibited high nutrient density, exceeding the Index of Nutritional Quality for most nutrients, excluding calcium and zinc.

Conclusions:

  • Bodybuilders significantly decrease dietary variety and the number of food items consumed as competition approaches.
  • The precompetition diet, while less varied, maintains a high nutrient density, with notable exceptions in calcium and zinc intake.
  • These findings highlight potential nutritional considerations for bodybuilders during intense contest preparation phases.
