chest pain

Objective: The present study aimed to compare the effectiveness of autogenic training and progressive muscle relaxation in improving the anxiety components of women with chest pain. Method: The research method was experimental with a pre-test-post-test design, a control group, and a three-month follow-up. The statistical population included all women with chest pain in Karaj city in 2021. using a purposeful sampling method, 60 patients with chest pain in Shahid Rajaei Hospital were selected and randomly assigned into three groups autogenic training, progressive muscle relaxation training, and control group. Autogenic training was provided in twelve 90-minute sessions, and progressive muscle relaxation intervention was administered in eight 2-hour sessions. Beck's (1988) anxiety questionnaires, Tylor & Cox (1998) revised anxiety sensitivity, and Rapee, et al (1996) perception of anxiety control was used to collect data. Data analysis was done using covariance analysis and post hoc test methods. Results: The results showed that autogenic training and progressive muscle relaxation alone have been effective in reducing anxiety symptoms, anxiety sensitivity and perception of anxiety control and autogenic training was more effective in improving anxiety components compared to progressive muscle relaxation (p<0.05). Conclusion: Considering the greater effectiveness of autogenic training on the anxiety components, it is suggested that relevant experts use this intervention to reduce the anxiety of patients with chest pain.

Aerobic power indicates the maximum amount of Oxygen intake that a person uses during strenuous physical activities under the sea. Accordingly, the significance of aerobic power in divers who spend much time under the water must be addressed. In order to investigate the matter, this study examines the correlation of aerobic power with increasing diving depth of divers and its relationship with their chest pain. The statistical population includes 70 students from a diving class of a Diving School in Bandar Anzali. The group consists of 20 male subjects randomly selected according to Morgan's table, aged 18 to 25, with no history of health issues, smoking, and professional sports activities. The results indicated a significant relationship between aerobic power and diving depth until the onset of chest pain; a significant inverse relationship between aerobic capacity and the intensity of chest pain; and a significant relationship was observed between aerobic capacity and duration of chest pain. These results are in favor of the effect of aerobic capacity in prevention of chest pain in divers.
