초록

The purpose was to examine improvements of performance and different physiological parameters in ten trained male cross-country mountain bikers after a supra-maximal interval training (SMIT) program of 8 sessions. Each session comprised 60 to 90 repeated 1-minute bouts consisting of a 20-s effort at 115% of maximal aerobic power (MAP), followed by 40-s recovery at 50% of MAP. Performance time to complete the virtual time-trial performance test was reduced significantly by -4.2%. Pulmonary sub-maximal oxygen consumption and deoxyhemoglobin in vastus lateralis decreased significantly by ‑4.7% and -21.9% respectively during the MAP test. Our findings suggest that SMIT program might improve performance and cycling efficiency in XC mountain bikers.
