HILO LIVING DOES NOT CHANGE VO2max BUT DOES INCREASE ANAEROBIC CAPACITY
Roberts, A. D., Martin, D. T., Gore, C. J., Hahn, A. G., Lee, H., Gawthorn, K. M., Dixon, J., Clark, S., & Slater, G. (2000). Live high:train low altitude exposure enhances anaerobic energy capacity. Medicine and Science in Sports and Exercise, 32(5), Supplement abstract 56.
Well-trained endurance athletes (13 male triathletes; 11 female road cyclists) served as subjects. A control group (C) and a live-high/train-low group (HiLo) of mixed gender were formed. Ss were measured for VO2max and maximal accumulated oxygen deficit. The C group lived and trained at 610 m. The HiLo group lived 8-10 hours per night in normobaric hypoxia at simulated altitudes of 2,650-3,000 m for 12 nights.
VO2max did not change in either group during training alone or training plus exposure. While the C group did not change in the anaerobic measure, the HiLo group did.
Implication. HiLo exposure does not increase VO2max, but does increase anaerobic energy system capacity.
