High-Intensity Interval Training (HIIT)
Sports Nutrition & Exercise Fueling
High-Intensity Interval Training (HIIT) uses repeated high-intensity intervals separated by recovery periods. Interval duration, intensity and total volume determine the session's actual demands.
Intermittent sports combine repeated intense actions with lower-intensity activity or pauses. Carbohydrate availability can support repeated work, while recovery between sessions or matches creates additional needs. Strength and power sports also require adequate energy and protein, with carbohydrate requirements shaped by the amount and density of training. A single brief effort does not describe the full day's demand. Match the food plan to warm-up, practice, competition, breaks and the next event rather than only the longest continuous effort.
Carbohydrate requirements vary with the intensity, duration and importance of the work. Daily intake relative to body mass describes a different quantity from an intake rate during exercise, which is commonly expressed per hour. A larger daily target does not mean the same amount should be consumed in every session. Match supply to the schedule, starting stores and practical tolerance, and distinguish grams eaten from grams absorbed or oxidized when discussing a fueling plan.
Muscle and liver glycogen have related but different roles. Muscle glycogen supplies the muscle in which it is stored, while liver glycogen helps support blood glucose. An overnight fast can reduce liver carbohydrate availability without producing the same depletion in every muscle. Starting concentration, recruited fibers and exercise demand affect use. An estimate of total stores does not directly describe the availability of every local glycogen pool during a specific movement.
For example, a team athlete may have limited eating opportunities during play but useful breaks before and between matches. Organize tolerated carbohydrate and fluid around those opportunities, then plan recovery for the next game. The position, time actually played and tournament schedule can matter more than assigning every teammate an identical food plan.
