该实验测试了运动后的焦虑状态和血压反应是否受到肌肉收缩类型的影响。在测试的第一天，11名志愿者分别完成了左右肢体的单次最大重复（1- rms）：手臂伸展，手臂屈曲。伸腿和屈腿（共8个练习）。在随后随机安排的两天里，受试者完成了24分钟的静态或动态锻炼。静态和动态运动条件均包括8个Emin运动时段，强度为1-RM的10%，中间间隔100万休息时间。在动态运动条件下。运动以每分钟收缩20次的速度进行。在此之前立即评估状态焦虑和血压。13. 运动后23分钟。在运动过程中连续评估心率，并在每个3轮运动周期的最后15秒内获得感知运动的总体评分。双向重复测量方差分析显示，静态和动态运动后，状态焦虑和收缩压降低到相似的程度。由此可见，急性运动后的焦虑和收缩压反应不受肌肉收缩类型的影响。
This experiment tested whether state anxiety and blood pressure responses to exercise were influenced by the type of muscular contraction performed. On testing day 1, 11 volunteers completed one-repetition maximums (1-RMs) separately for the right and left limbs: arm extension, arm flexion. leg extension and leg flexion (8 total exercises). On two subsequent days, which were randomly ordered, subjects completed 24 minutes of either static or dynamic exercise. Both the static and dynamic exercise conditions involved eight Emin exercise periods performed at an intensity equal to 10% of 1-RM and separated by a 1-mln rest period. In the dynamic exercise condition. exercise was performed at a rate of 20 contractions-min-'. State anxiety and blood pressure were assessed immediately before as well as 3. 13. and 23 minutes following exercise. Heart rate was assessed continuously during exercise, and overall ratings of perceived exertion were obtained during the last 15 seconds of each 3-rnin exercise period. Two-way repeated measures ANOVAs revealed that state anxiety and systolic blood pressure were reduced to a similar degree following both static and dynamic exercise. It is concluded that anxiety and systolic blood pressure responses to acute exercise are not mediated by the type of muscle contraction performed.
