Optimal frequency of jogging for a long periods. Part I / 体力科学

ABSTRACT

This study was performed to investigate the optimal frequency of jogging in order to prescribe a jogging to myself as the subject. The program of jogging training was composed of two parts; I) jogging about 4 km 4 days a week for 12.5 years (having started from age of 50 years old), and then stop jogging for about 6 weeks, and II) jogging once a 5 days for 1 year. Blood pressure, blood components and the frequency of arrhythmias appearance were measured and discussed.<BR>After 4 years from starting jogging at age of 50 years old, ventricular premature contraction (VPC) was observed, and then after 10 years VPC, including multifocal VPC, couplets and 3 consecutive VPC was observed frequently, especially after jogging. Therefore, jogging was stopped for about 6 weeks. In 2 nd part of jogging, no arrhythmias appeared in jogging once a 5 days. The recordings of blood pressure and blood components were normal and exercise-induced stress by a low frequency of jogging didn't increase.<BR>Consequently it should be suitable to prescribe a jogging once a 5 days to myself.
