Fat gain in female swimmers

Area of Science:

• Sports Science
• Human Nutrition
• Body Composition Analysis

Background:

• Diet and body composition are key factors in athletic performance.
• Understanding the interplay between nutrition, training, and body fat is crucial for athletes.

Purpose of the Study:

• To investigate the relationship between dietary fat intake and body fat percentage in elite female swimmers.
• To examine the effects of detraining on diet and body composition in these athletes.

Main Methods:

• Longitudinal study over 13 months with nutritional supervision.
• Comparison between 6 elite swimmers and 11 untrained females matched for fat-free mass.
• Analysis of body weight, fat mass, and dietary energy intake before and after a 2-month detraining period.

Main Results:

• A significant positive correlation was found between dietary fat percentage and body fat percentage in untrained subjects.
• This correlation remained consistent when elite swimmers' data were included.
• Detraining for 2 months led to a significant increase in body weight and fat mass in swimmers.

Conclusions:

• Exercise training does not alter the fundamental association between diet and body composition.
• Detraining prompts body fat gain, potentially aiding in restoring energy balance.
• Nutritional strategies should consider the impact of training cessation on body composition.
