The purpose of this study was to determine whether aerobic fitness training for a four week period can be a useful stress coping method in acculturative stress. To measure its efficacy, the stress profile procedure was applied to compare physiological reactivity (heart rate : HR, skin temperature : ST, skin conductance level : SCL, and trapezius electromyographic activity : EMG) to psychological stress task (arithmetic) between the pre - and post - training tests. Twenty four female Japanese students participated in each of the following three groups : aerobic exercise (AE), HR biofeedback assisted relaxation (BF), and control (C).
　Results revealed that the AE and BF groups had significantly smaller HR reactivity at some time points during the recovery period in the post-training test than did the C group. However, other physiological measures did not show differences between groups. After controlling for the length of residence, the AE group had significantly smaller HR and EMG reactivities in the post training test compared to the C group.
　The aerobic exercise training may not be a enough period to improve the reactivity to psychological stress in this study. A discussion followed about the coping effects of aerobic exercise on the type of stress symptom.
