The present study was to evaluated the effects of habitual physical exercise on the aortic pulse were velocity index (PWVI : PWV adjusted for diastolic blood pressure), in relation to the beginning age and duration of training. The study groups consisted of 41 male runners (Presently Active) aged 30-66 years who had been involved in intense training for over 2 years (9.8± 4.8, mean± SD), and 93 healthy inactive males (Presently Inactive) aged 30-69 years who had not engaged in regular exercise during the recent 10 years. The Presently Active and Presently Inactive groups were each divided into 2 subgroups depending on whether they participated in the vigorous sports activities as youths (10 to 25 years of age). The Presently Active group included 12 subjects who were active as youths and 29 subjects who were inactive as youths. The Presently Inactive group contained 16 subjects who were active as youths and 77 who were inactive as youths. The Presently Active group showed a slower PWVI, i, e, higher extensibility of the aorta, as compared to those parameters in the Presently Inactive group, regardless of vigorous sports participation as youths. There was no significant defference in the PWVI value between the presently inactive subgroups with and without vigorous sports participation in youth. It is suggested that vigorous physical exercise for several years may provide individuals with an extensible aorta independent of age at the beginning of trainning, but the effect of physical exercise cannot be perpetuated over the long-term, without continuing physical exercise.
