About this trial
With an increase in number of female athletes in sport events, it is becoming more important to gain insight in female related sports physiology. A main difference between male anf female athletes is the menstrual cycle. During the menstrual cycle, female reproductive hormones fluctuate. These hormones are also of influence on endurance, recovery, muscle strenght and mental state. Therefore we hypothesize that training efficiancy, power and motivation to train differ during the menstrual cycle. In case there is a pattern seen during the menstrual cycle, training programs can be individualized taking the menstrual cycle into account leading to more effective training programs.

Trial outcomes
Primary outcomes
1
Health of menstrual cycle in amateur cyclist
It is known that the incidence of amenorrhea is about 15% of the professional female athletes. This has many short- and long term health consequences. These health consequences can be avoided since developing amenorrhea is preventable. It is unknown how many amateur cyclist have an irregular period or have amenorrhea. Insight in the size of this health problem creates a window of opportunity in preventive medicine.

Objective training parameters during the menstral cycle
By collecting details in regards to the menstrual cycle in combination with objective parameters (heart rate, power, speed, endurance) of training it is possible to investigate whether these objective parameters are influenced by the hormonal fluctuations during the menstrual cycle.
Time frame
2 years3
Subjective training parameters during the menstrual cycle
By collecting details in regards to the menstrual cycle in combination with subjective parameters (fatigue, discomfort, readiness, motivation) of training it is possible to investigate whether these subjective parameters are influenced by the hormonal fluctuations during the menstrual cycle.

Is menstrual cycle-based periodized training feasible in the future?
In case the menstrual cycle affects objective and subject training parameters, it might be feasible to adjust the training program based on the phase of the menstrual cycle.
Time frame
2 years2
Does the menstrual cycle affect recovery?
Improving endurance, muscle strength and power is not only training, but also the quality of recovery. Therefore, it is interesting to investigate whether the hormonal changes during the menstrual cycle affect recovery (i.e. readiness).

Questionnaires
Out of the complete cohort included, it is possible to select a specific group of cyclist to dive deeper into menstrual cycle related training parameters
Time frame
3 years2
Excercise testing
Out of the complete cohort included, it is possible to select a specific group of cyclist who can be invited to perform excercise tests during different moments of the menstrual cycle.
