Question

rachel wants to improve her body composition by reducing her bmi. she swims with her friends after school two days a week and eats a well - balanced diet. what else should she do to ensure that she properly applies all the necessary fitt principles in her plan? a. she should add more cardiovascular training and weight training to her exercise routine and eat several low - calorie meals throughout the day. b. she should increase her swimming workouts to five days a week and eat a high - calorie diet that equals 2,500 calories. c. she should add a few days of weight training to her exercise routine and consume 4,000 calories a day. d. she should eat a high - protein, low - carbohydrate diet and add five days of weight training to her exercise routine.

Explanation:

Current swimming only covers 2 days/week (low frequency) and one type of cardio. Adding more cardio and weight training increases exercise frequency and expands the type of training, addressing FITT's frequency and type components.

1. Eating several low-calorie meals supports a calorie deficit (needed for BMI reduction) while maintaining consistent energy, aligning with the nutritional component of body composition improvement.
2. Options B, C, and D are incorrect: high-calorie/4000-calorie diets would hinder BMI reduction, and adding 5 days of weight training alone (without balanced cardio or appropriate diet) does not fully address all FITT and weight management needs.
