| ABSTRACT | |||
| Pre-participation screening is very important for prescribing
and practising exercise safely. The aim of this study was to investigate
both ratings of perceived exertion (RPE) and blood pressure responses in
two different types of exercises with matching duration and indirectly determined
working heart rate (HR). Participants were 23 male students, who were generally
healthy but sedentary. The time course of their RPE and blood pressure during
a 50- minute work-out session on an arm crank ergometer and a cross trainer
were compared. RM-ANOVA showed both a higher RPE (p < 0.001) and diastolic
blood pressure (DBP) (p < 0.001) response to the arm exercise that were
shown significantly correlated (r = 0.883; p = 0.008). Linear regression
analysis (p = 0.001) confirmed the ability to predict the time course of
DBP by knowing the RPE on the arm crank ergometer. Even if people use the
recommended relative intensity, the HR method is not always safe for health
without pre-participation screening because exercise characteristics can
negatively influence physiological responses. The HR method could be substituted
by the RPE method. Key words: Diastolic blood pressure, arm crank ergometer, cross trainer. |
