0.05). Specifically, the indicatorsin male and female are as follows respectively: 1) Heart rate is 61bpm and 62bpm, a normal person is75bpm
2) The cardiac axis (angle α) tends to deviate to the left by α = 590 and α = 610, compared with= 650
3) P wave: mean duration is (96 ms and 94 ms, versus 80 ms)
average amplitudes are (14.4mmand 13.9mm, compared to 12mm)
4) The average PR segment time is 177ms and 167ms, compared to150ms
5) QRS complex: mean time 78ms and female 74ms, compared to 70ms

6) T wave amplitude: young male athletes,male athletes, female athletes and young female athletes are 6.3±1.9 mm, 8.7±2.6 mm, 8.5±2.9 mmand 6,4±1,6 mm compared to 6, respectively, up to 12mm
7) The QT interval in young male athletes,male athletes, female athletes and young female athletes were 359± 0 ms, 366± 6ms, 63±15 ms and379±13ms, compared with 0.36s in men and 0.37s in women
The QTc interval in young male athletes,male athletes, young female athletes and female athletes was 417 ± 8 ms, 437 ± 9 ms, 424 ± 9 ms and455 ± 8.5 ms, compared with normal people: QTc is >
440ms in men or >
460ms in women. Gender andexercise time affect EKG characteristics: 1) The mean QTc interval in men is 437 ± 9 ms and 455 ±8.5ms in women, compared with normal men <
440ms and female <
460ms
2) The QTc interval in maleathletes is shorter than in female athletes: male athletes are 437 ± 9 ms
young male athletes is 417 ± 8ms
female athletes is 442 ± 8 ms and young female athletes is 424 ± 9 ms
T wave amplitude in maleathletes is 8.7 ± 2.6 mm
female athletes is 8.0 ± 2.9 mm.
