Mean ± standard deviation. Mean HR = mean hear rate; Mean RR = mean RR intervals; SDNN = standard deviation of all normal RR intervals written in milliseconds; RMSSD = square root of the square mean of the differences of the adjacent normal RR intervals, in milliseconds; LF ms² = low-frequency component in milliseconds squared; LF nu = low frequency component in unit of measurement; HF ms² = high-frequency component in milliseconds squared; HF nu = high-frequency component in unit of measurement; LF/HF = balance between the low and high frequency component; beat/min = beat per minute; SBP = systolic blood pressure; DBP = diastolic blood pressure; mmHg = millimetres of mercury; HSG = high intensity aerobic exercise combined strength group; CG = control group; Pre = pre-training; Post = post-training; |
