From: Degree of exercise intensity during continuous chest compression in upper-body-trained individuals
Comparisons of changes in heart rate and rating of perceived exertion during 10-min chest compression between groups. HR heart rate, RPE rating of perceived exertion. *P < 0.05, **P < 0.01, and ***P < 0.001, compared with the value at rest for HR. # P < 0.05, ## P < 0.01, and ### P < 0.001, compared with the value at the first minute of chest compression for RPE. a P < 0.05 and aa P < 0.01, between values in the group of sedentary individuals and the group of swimmers
