We found that colour discrimination was better at ovulation than at the other 2 time points. It is possible that psychological as well as hormonal factors could contribute to improved colour vision performance at ovulation.
Heart rate alteration during a constant load exercise in the different menstrual phases
2012
In fitness centres, the most common way to modulate exercise’s intensity is heart rate (HR) control and therefore training at constant heart rate (CHR) is widely used but this method assume that exercise’s response to exercise should be always the same; Instead there are conflicting results about menstrual cycle’s effects on physiological response to exercise (Jense de Jonge 2003). Many researches have investigated the influences of estrogenic hormone levels in sport performance (Sarwar 2006; Phililps 1996), muscle strength and heart rate during maximal and submaximal exercise (Oosthuyse 2005; Kishali 2006). No study has attempt to verify if CHR correspond to a constant load of endurance ex…
