Abstract:Objective To assess the heart rate (HR) and blood pressure (BP) response to exercise stress test in the recruits with different mental state. Methods The SCL-90 item Hopkins Symptom Checklist (SCL-90) was used to assess the mental state of the recruits. 40 soldiers, whose score> 160 points, were included in the study group, and another 40 soldiers with score <160 points were assigned to the control group. Both groups of participants were tested with the standard Bruce treadmill protocol from step 3, and the heart rate and blood pressure were measured at rest, every minute during the exercise stress test and every minutes during recovery stage using standard laboratory procedures. Results The number of soldiers reached maximal exercise in study group was lower than that in the control group, accompanied by increased adverse reactions such as dizziness and chest distress. Compared with the control group, the study group had higher basal heart rate before test[(80.0±9.8) beats/min vs (69.2±9.2) beats/min,P=0.023], abnormally high diastolic blood pressure[(96.6±6.4) mmHg vs (78.4±8.3) mmHg,P=0.013]accompanied by decreased heart rate during maximal exercise, and slower heart rate recovery after exercise. Conclusions There are significant differences in the cardiovascular system response to exercise stress test in the recruits with different mental state. Increased adverse reactions are observed in low mental quality group of recruits, which may be related to secretion imbalance of stress hormones.
