Response of central arterial stiffness and morning BP surge to acute SJL when including those who did not adhere to the intervention in the SJL trial
Although there were significant interactions in cfPWV, morning BP surge, and time course of ambulatory SBP, the significant interactions disappeared when including participants who did not adhere to the intervention in the SJL trial (SJL < 2 h). The results suggest that acute small SJL ( < 2 h) does not influence cardiovascular system in healthy men. As the present study could not clarify how many hours of SJL influence the cardiovascular system, further study is necessary.
