In brief: The excellent endurance capacities of ten members of the Finnish motocross team, studied before and after a three-month program stressing endurance and strength, showed further improvement with intense training. Before the program they had 12.2% body fat and maximal oxygen consumption of 64.7 ml· kg(-1)· min(-1) during bicycle ergometry. After the program, fat decreased 7.7%, weight decreased insignificantly, VO2 max increased 12.4%, and anaerobic thresholds (AT) increased 21%, averaging 37.3 ml· kg(-1)· min(-1) (56.1% of VO(2) max). Heart rates at the AT increased 11.7%. Most physiological variables improved more at the AT than at maximum.
芬兰摩托车越野赛队的十名队员在接受了为期三个月的耐力和力量强化训练计划前后接受了研究，其出色的耐力能力在高强度训练后进一步提高。在该计划实施前，他们的体脂率为12.2%，在自行车测力计测试中最大摄氧量为64.7毫升·千克⁻¹·分钟⁻¹。计划实施后，脂肪减少了7.7%，体重无显著下降，最大摄氧量增加了12.4%，无氧阈（AT）增加了21%，平均为37.3毫升·千克⁻¹·分钟⁻¹（最大摄氧量的56.1%）。无氧阈时的心率增加了11.7%。大多数生理变量在无氧阈时的改善比在最大值时更多。
