Does periodic physical exercise reduce pulse wave velocity in healthy female college students?
Periodic physical exercise is associated with lower arterial stiffness, as measured by pulse wave velocity, in young healthy females.
Physical activity was associated with lower arterial stiffness in young females; hypothesis-generating for causal effects on pulse wave velocity.
Objective The purpose of this study was to examine effects of periodic physical exercise on pulse wave velocity (PWV) with 32 healthy female college students.Methods PWV was measured using VaSera VS-1000 (Fukuda denshi, Co., Ltd, Tokyo, Japan) . PWV was measured at rest in supine position with sensory cuffs wrapped to their both brachials and ankles (brachial-ankle method, baPWV) . baPWV was calculated by dividing the distances (D) from the aorta to the cuff on the left (right) brachial and to that on the left (right) ankle by each pulse transit time (t) . That is, baPWV was calculated as: baPWV=D/t.Result and Discussion All subjects were studied for analysis of the relations of exercise frequency with left-baPWV (L-PWV), right-baPWV (R-PWV) and the each was found significantly correlated. Then, we compared PWV between subjects doing periodic physical exercise (active group, n=14) and those doing no periodic physical exercise (inactive group, n=18) . Both L-PWV and R-PWV values were lower in the active group than in the inactive group showing their lower arterial stiffness.Conclusion These results suggested that young people are also able to reduce arterial stiffness and to prevent the lifestyle related diseases by doing periodic physical exercise.
