What do you improve during LSDT?

• A. Endurance
• B. VO2 max
• C. Maximum sprint speed
• D. Peak power

Answer: (A)

Long Slow Distance Training builds endurance by training the aerobic system through extended, low-to-moderate intensity work. The body adapts to use oxygen more efficiently, increasing mitochondrial density and capillarization in the muscles, improving fat oxidation, and enhancing overall efficiency. These changes raise your ability to sustain effort for longer and delay fatigue, which is the essence of endurance. VO2 max can improve but typically only modestly with LSD alone, because the emphasis is on sustaining submaximal effort rather than pushing to maximal oxygen uptake. In contrast, maximum sprint speed and peak power depend largely on anaerobic power and neuromuscular factors, which require high-intensity, explosive training rather than long, easy mileage; LSD alone won’t drive those peak power adaptations.
