CONTEXT
Slideboard exercise is consistent with the American College of Sports Medicine guidelines for exercise intensity of 55% to 90% of maximal heart rate or 40% to 85% of maximal oxygen uptake.
OBJECTIVE
To determine if slideboard exercise while in a leg harness increases the metabolic and cardiorespiratory demands.
DESIGN
Repeated-measures design.
SETTING
Athletic Training Research Laboratory.
PATIENTS OR OTHER PARTICIPANTS
Sixteen volunteers from the university community.
INTERVENTION(S): Subjects performed 2 graded slideboard exercise tests with and without the leg harness, each 2-minute stage ranging from 46 to 90 slides per minute.
MAIN OUTCOME MEASURE(S): We measured maximal oxygen uptake, heart rate, blood lactate, respiratory exchange ratio, ratings of perceived exertion, and total time to exhaustion during each session.
RESULTS
Significant decreases in maximal oxygen uptake and blood lactate were observed when the leg harness was used.
CONCLUSIONS
Performance was hindered when subjects wore the leg harness during the slideboard exercise.
背景
滑板运动符合美国运动医学学会关于运动强度的指南，即最大心率的55%至90%或最大摄氧量的40%至85%。
目的
确定在腿部系上安全带进行滑板运动时，是否会增加代谢和心肺功能需求。
设计
重复测量设计。
地点
运动训练研究实验室。
患者或其他参与者
来自大学社区的16名志愿者。
干预措施
受试者进行了2次分级滑板运动测试，一次系腿部安全带，一次不系，每个2分钟阶段的速度为每分钟46至90次滑动。
主要观察指标
我们测量了每次测试期间的最大摄氧量、心率、血乳酸、呼吸交换率、主观用力程度评分和疲劳总时间。
结果
使用腿部安全带时，最大摄氧量和血乳酸显著降低。
结论
在滑板运动中，受试者佩戴腿部安全带时运动表现受到阻碍。
