Relationship between sleep quality and functional Cardiovascular Variables in active and none-active young women

Poor sleep quality lead to cardiovascular dysfunction. Present study was aimed to investigate the relationship between sleep quality and functional cardiovascular indexes and their comparison in active and none-active young women.

Thirty healthy young women were randomly assigned in two active (n=15) and none-active (n=15) groups. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The functional cardiovascular indexes including systolic and diastolic blood pressure mean arterial pressure, resting and maximal heart rate, VO2max, resting and maximal rate pressure product and resting and maximal oxygen pulse were measured. The data was processed by using SPSS version 22 and Mann-Whitney u and Multiple Linear Regression.

A significant increase showed in VO2max (p< 0.001) and resting (p< 0.001) and maximal oxygen pulse (p< 0.001) in active group compared with the none-active group. Maximal heart rate (p= 0.047) and score of sleep quality index (p= 0.018) in active group was significantly lower than none-active group. In active group with increasing in functional cardiovascular indexes an insignificant reduction in score of sleep quality were observed. In in-active group with increasing in resting heart rate (P-value= 0.047), systolic blood pressure (p< 0.001), mean arterial pressure (p< 0.001) and resting (p= 0.046) and maximal (p= 0.048) rate pressure product a significant increase in score of sleep quality was observed.

The results indicated that, regular physical activity led to improve cardiovascular function and sleep quality in young women sleep quality.
