Present study aimed to examine the effects of high-intensity intermittent training on metabolic or circulatory parameters and exercise time during 30s-lasting exhaustive exercise. Six healthy males (22 ± 1yrs) had an intermittent training four days a week for four weeks. The intermittent training consisted of 8 or more sets of 20s exercise bout at an intensity of 170%VO2 max separated by 10-s recovery. Before and after training period, VO2 max and maximal accumulated O2 deficit (MAOD) were determined as indices of metabolic capacity. During 30s-lasting exhaustive exercise, VO2, O2 deficit, and circulatory parameters, such as heart rate, stroke volume, and cardiac output, were also determined every 10s. After the training, VO2 max and MAOD were significantly increased. During 30s-lasting exhaustive exercise, exercise time, stroke volume, and cardiac output were also significantly enhanced. However, no significant differences were observed in VO2 and O2 deficit every 10s during 30s-lasting exhaustive exercise. Therefore, these findings suggest that high-intensity intermittent training enhances exercise time during 30s-lasting exhaustive exercise and that the improvement of exercise performance is closely related to an increase in anaerobic capacity.

Objective: We investigated the association between catastrophizing with regard to numbness and pain, subjective symptoms, upper extremity function, and disability in cancer patients with chemotherapy-induced peripheral neuropathy (CIPN). Method: We evaluated catastrophizing (pain catastrophizing scale [PCS] total score, rumination, helplessness, magnification), subjective symptoms of numbness and pain, upper extremity function, and disability in patients with hematological malignancy and gastrointestinal cancer who developed upper extremity CIPN. We calculated the Spearman’s rank correlation coefficient to determine the strength of the association. Result: A significant association was observed between catastrophizing and disability; however, upper extremity function was not significantly association with catastrophizing. Based on the PCS subscale scores, only rumination was significantly association with subjective symptoms. Conclusion: Functional assessment and approaches may not be sufficient to improve the activities of daily living in cancer patients with upper extremity CIPN, and assessment and approaches to cognitive aspects, such as catastrophizing, should also be considered.
