Comparison of Menstrual Function Among Sprinters, Long Marathon Runners, and Non-athletic Females: An Observational Study

The purpose of this study is to compare between sprinters and long marathon in menstrual characteristics and serum estradiol level.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Menstrual function and dysfunction conversations have long been stigmatized both in the general population and in sport settings (O'Flynn, 2006). However, Discussions of menstruation in the sport context often focuses on the impact of physical menstrual symptoms and dysfunction on activities such as training and sport performance (Bruinvels et al., 2016; Knowles et al., 2019). In addition, no study had been compare between sprinters and long-marathon runners in menstrual characteristics and estradiol level. Therefore, the purpose of this study to compare between sprinters and long marathon in menstrual characteristics and serum estradiol level.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
serum estradiol level
Time Frame: 3 months
Blood samples were obtained on the 2nd day of the menstrual cycle at 10.00 a.m. following overnight fasting and rest. The athletic females were instructed to refrain from performing strenuous exercise on the day of sampling. Blood samples were separated and stored at -80°C till analysis of serum estradiol levels. Serum estradiol levels were measured to evaluate the menstrual function. The manufacturer indicated the following reference intervals for healthy females: Estradiol 40-350 pg/ml.
3 months
Menstrual history characteristics
Time Frame: 3 months
The age at menarche (in years), the number of menstrual cycles in the past year, and the length of menstrual cycles (in days) were collected through a self-administered questionnaire to evaluate the menstrual status of each female participant.
3 months
Age of participation to sport
Time Frame: 3 months
It was taken in years from each female athlete through a self-administered questionnaire.
3 months
Weekly training workload
Time Frame: 3 months
It was taken in hours per week from each female athlete through a self-administered questionnaire.
3 months
Training experience
Time Frame: 3 months
The training experience of the athlete was then calculated by subtracting her age of participation in sport from her chronological age.
