Exercise and Muscle Performance

2.3K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Summary
This summary is machine-generated.

High-intensity functional training (HIFT) athletes often have nutrient gaps, with many using dietary supplements (DS) to compensate. Few consume recommended whole food servings, highlighting potential reliance on DS for health and recovery.

Area of Science:

  • Exercise Science
  • Nutritional Science
  • Sports Medicine

Background:

  • High-intensity functional training (HIFT) popularity has surged.
  • Previous research often focused on elite athletes and quantitative methods.
  • Limited understanding of typical HIFT athletes' nutrition and body composition exists.

Purpose of the Study:

  • To comprehensively describe common dietary habits and body composition in HIFT athletes.
  • To explore dietary supplement (DS) use and rationales among HIFT athletes.

Main Methods:

  • Descriptive analysis of data from 62 HIFT athletes.
  • Body fat percentage (BF%) estimation using a 3-compartment model.
  • Online questionnaire assessing dietary habits, DS use, and rationales, with inductive thematic analysis for qualitative data.

Main Results:

  • Body composition varied significantly between male and female HIFT athletes.
  • Most participants consumed lean meats and home-cooked meals but few met recommendations for dairy, fruits, vegetables, and whole grains.
  • 77.4% of HIFT athletes used an average of six DS, commonly dairy protein, creatine, caffeine, and electrolyte drinks, often to improve health, recovery, and nutrient intake.

Conclusions:

  • Many HIFT athletes may use DS to fill nutritional gaps instead of whole foods.
  • Dietary supplement use is prevalent, with common motivations including health, recovery, and nutrient intake.
  • Findings highlight potential areas for nutritional guidance within the HIFT community.
