The influence of repeated sprints over the aerobic performance at swimmers

Table 4:

Correlation between heart rate and lactic acid level
Right linear regression Y = α + β × X
Y = Heart rate or heart rate increase (heart rate difference after test - heart rate before test) X = Lactic acid level Y = Heart rate difference after heart rate before test X = Lactic acid level
Date of the test Size Y Coefficient β (slope of the regression line) 95% confidence interval of b β Pfor β R2 Square of the regression coefficient Pfor regression
11.02.2015 HR before the race -0.50 -0.24; -0.14 0.576 0.024 0.576
15.07.2015 HR before the race 0.13 -0.07; 0.34 0.178 0.135 0.178
11.02.2015 HR after the race -0.43 -0.21; 0.12 0.585 0.024 0.585
15.07.2015 HR after the race 0.13 -0.13; 0.28 0.070 0.230 0.069
11.02.2015 HR increase after test 0.02 -0.11; 0.10 0.970 0.001 0.970
15.07.2015 HR increase after test 0.05 -0.10; 0.19 0.516 0.033 0.516
There was no correlation between heart rate and lactic acid. A weak positive association trend at the limit of statistical significance with lactic acid level was observed for heart rate after the test on 15.07.2015.
