WebPhysiologic Responses and Long-Term Adaptations to Exercise is generally much higher in these patients, likely owing to a lesser reduction in total peripheral resistance. For the first 2 to 3 hours following exercise, blood pressure drops below preexercise resting lev-els, a phenomenon referred to as postexercise hy-potension (Isea et al. 1994). WebStudies have shown that a high carbohydrate, low salt diet can help people adapt to altitude and reduce their chances of altitude sickness.
