Roles of Food Types during Exercise - Fats

Fat

* fat provides a concentrated source of energy - it provides more than twice the energy that cabs and protein do. Protein and carbs provide four calories per gram whilst fat provides nine.

* it helps to fuel low-moderate intensity activity. At rest and during exercise which is below 65% of your aerobic capacity (amount of oxygen available) - fat contributes 50% or more of the energy that your muscles need

* fat aids endurance exercise by sparing your glycogen reserves. Usually as the distance or duration of your exercise increaeses the intensity decreases thus fat becomes more important as a fuel source.
