This study examined the post-exercise hypotension (PEH) effect after different sprint interval training (SIT) protocols in matched young and older adults. The results showed that there were no significant differences in blood pressure and heart rate between the two age groups after SIT1 and SIT3. This suggests that age does not affect PEH after SIT.
This study assessed the post-exercise hypotension (PEH) effect in a sample of matched young and older adults after different sprint interval training (SIT) protocols. From forty-three participants enrolled in this study, twelve younger (24 +/- 3 years) and 12 older (50 +/- 7 years) participants, matched for the body mass index, systolic blood pressure, and VO(2)max-percentiles, were selected. The participants completed two SIT protocols consisting of 4 x 30 s exercise bouts interspersed by either one (SIT1) or three minutes (SIT3) of active rest. The peripheral systolic (pSBP) and diastolic (pDBP) blood pressure, central systolic (cSBP) and diastolic (cDBP) blood pressure, pulse wave velocity (PWV), and heart rate (HR) were obtained before and at different measurement time points (t5, t15, t30, t45) after the exercise. No significant time x group interactions were detected in pSBP (p = 0.242, eta(2) = 0.060), pDBP (p = 0.379, eta(2) = 0.046), cSBP (p = 0.091, eta(2) = 0.861), cDBP (p = 0.625, eta(2) = 0.033), PWV (p = 0.133, eta(2) = 0.076), and HR (p = 0.190, eta(2) = 0.123) after SIT1. For SIT3 no significant time x group interactions could be detected for pSBP (p = 0.773, eta(2) = 0.020), pDBP (p = 0.972, eta(2) = 0.006), cSBP (p = 0.239, eta(2) = 0.060), cDBP (p = 0.535, eta(2) = 0.036), PWV (p = 0.402, eta(2) = 0.044), and HR (p = 0.933, eta(2) = 0.009). Matched samples of young and older adults reveal similar PEH effects after HIIT. Accordingly, age does not seem to affect PEH after SIT. These results show that rest interval length and age modulate the PEH effect after SIT.
