From: Impact of physical fitness and biometric data on the quality of external chest compression: a randomised, crossover trial

Figure 4

Minute-to-minute results of external chest compression performed by male participants for 30:2 in correlation to physical fitness determined by the heart rate at 75 watts of rowing (HR 75 ). A: compression depth, lower vs. higher HR75: p < 0.001; B: compression rate, lower vs. higher HR75: p < 0.001. Black squares = low HR75; white squares = high HR75. Asterisks indicate significant differences comparing the first minute with the subsequent minutes of compression within each group. *: p < 0.1; **: p < 0.05; ***: p < 0.01. Data are presented as mean ± standard error of mean. For the definition of lower and higher HR75 please refer to the main text.
