Acute Hemodynamic Responses to Combined Exercise and Sauna

This study investigated acute hemodynamic, plasma volume and immunological
responses to four loading protocols: sauna only, and sauna after endurance,
strength or combined endurance and strength exercise. Twenty-seven healthy,
slightly prehypertensive men (age 32.7±6.9 years) were measured at PRE,
MID (after exercise), POST, POST30min and POST24h. The measurements consisted
systolic and diastolic blood pressure, heart rate, body temperature and
concentrations of high-sensitive C-reactive protein, white blood cells and
plasma volume measurements. Endurance+sauna showed significant decreases
in systolic blood pressure at POST (–8.9 mmHg), POST30min (–11.0
mmHg) and POST24h (–4.6 mmHg). At POST30min, significant decreases were
also observed in sauna (–4.3 mmHg) and combined+sauna
(–7.5 mmHg). Diastolic blood pressure decreased significantly from -5.4
to –3.9 mmHg at POST in all loadings. Plasma volume decreased
significantly at MID in all exercise loadings and at POST in
endurance+sauna and strength+sauna. Plasma volume increased
significantly (p < 0.01) in endurance+sauna and
combined+sauna at POST24h. White blood cells increased following all
exercise+sauna loadings at MID, POST and POST30min, whereas high
sensitive C-reactive protein showed no changes at any measurement point. The
