(During effort).
· Supine position: the analysis of the variance
shows a significant effect F (2) = 12.67; p <0.05 Ramadan fasting on the
mean values LF (ms2) (Figure 3).
The post hoc analysis shows that the LF values recorded
before Ramadan are significantly higher than those measured in the middle and
at the end of the month of fasting P <0.05.
· Standing position: The analysis of the variance
shows a significant effect F (2) = 12.22, p <0.05 Ramadan fasting on the
mean values LF (ms2) (Figure 3).
The post hoc analysis shows that the LF values recorded
before Ramadan, when standing, are significantly higher than those measured in
the middle and at the end of the month of fasting p <0.05.

During effort: The analysis of the variance shows a
significant effect F (2) = 11,52; p <0.05 Ramadan fasting on mean values LF
(ms2) after exercise (Figure 3).
The post hoc analysis shows that the LF values recorded before
Ramadan, during exercise, are significantly higher than those measured in the
middle and at the end of the month of fasting (P <0.05).

· Supine position: The Analysis of the variance
shows a significant effect F (2) = 11.66; P <0.05 Ramadan fasting on mean
values LF (nu) (Figure 4).
The post hoc analysis shows that the LF values recorded
before Ramadan, in supine position are significantly higher than those measured
in the middle and at the end of Ramadan (P <0.05).
· Standing position: The analysis of the variance
shows a significant effect F (2) = 11,23; P <0.05 of Ramadan fasting on the
mean LF values (Figure 4).

The post hoc analysis shows that the LF values recorded before
Ramadan, while standing, are significantly higher than those measured in the
middle and at the end of the month of Ramadan (P <0.05).
· During effort: The analysis of the variance
shows a significant effect F (2) = 10.55; P <0.05 of Ramadan fasting on mean
values LF (nu) (Figure 4).
The post hoc analysis shows that the LF values recorded
before Ramadan, during the effort, are significantly higher than those measured
in the middle and at the end of the month of Ramadan (P <0.05).
