Energy balance

Weekly training volume was approximately 90% lower in the sprint-trained group compared to the endurance-trained group.

Sprint training offers a time-efficient alternative to traditional endurance training with significantly lower energy expenditure.

StrongSupportsmedium confidence
This is particularly impressive given that weekly training volume was ∼90% lower in the sprint-trained group (∼225 versus 2250 kJ week−1).
