Abstract:
Objective To explore the differences in energy contribution between 1500 m speed skat-ing and cycling maximal exercise.Methods Eleven professional skaters took the tests of 1500 m speed skating and cycling maximal exercise,respectively.A portable gas analyzer and a blood lactate analyz-er were used to measure and assess the gas metabolism during and 6 minutes after the tests,along with the blood lactate level before and after them.The energy contribution and contribution rates were calculated by using the phosphoric acid-lactic acid-oxygen method.Results There were significant dif-ferences between the two tests in the average accumulated oxygen uptake(5.52±0.99 L vs 5.94±0.75 L,P=0.043,ES=0.481)and the rapid recovery of oxygen uptake after exercise(2.07±0.67 L vs 1.52±0.86 L,P=0.029,ES=0.746).However,no significant differences were found in the rela-tive anaerobic lactic contribution between the two different exercises.Moreover,the relative anaerobic alactic contribution of speed skating was significantly greater than cycling(21.36%±4.12%vs 15.39%±5.89%,P=0.010,ES=1.211),while the relative aerobic contribution was significantly lower than the latter(52.31%±5.45%vs 57.13%±5.12%,P=0.016,ES=0.913).Conclusions The energy contri-bution of 1500 m speed skating is different from the cycling maximal exercise,indicating that the rel-ative aerobic contribution differs among different exercises.Therefore,future training plans should be tailored to the specific energy contribution characteristics of each sport and speed skaters should strengthen their explosive training when taking cycling as the main training method in non-ice periods.
