Age of menarche in various categories of Indian sportswomen.

Abstract

Data on the age of menarche has been collected on 264 Indian sportswomen, and 108 girls forming the control group, all hailing from the Punjab, Haryana, chandigarh and Delhi. Outstanding athletes and players of hockey, basketball and volleyball were included. The combined mean age at menarche for sportswomen is 15.21 years and for the control sample is 14.05 years. The differences in the two series are statistically significant. The mean age at menarche in hockey, basketball, volleyball and athletes is found to be 15.15, 15.40, 15.05 and 15.27 years respectively. The differences in these groups, however, are not found to be statistically significant.

A Comparative Study of Understanding of Menstrual Process among Married Women Belonging to Two Ecological Settings

“…The age at menarche is widely considered as an important landmark in sexual maturity (Sidhu and Grewal, 1980). However, it varies widely, even within the same population and is influenced by many factors like climate, geographical, socioeconomic conditions and many other factors of genetic and non-genetic nature (Mehta et al, 1991).…”

Age at menarche in Nigerian athletes.

“…For the purpose of the study and analysis of data the following four groups were constituted: Group A: Control subjects (non-athletes) Group B: Combined samples of athletes Group C: Athletes with regular sports starting before menarche Group D: Athletes with regular sports only after menarche participation participation The test for significance in the difference between the means of various groups was calculated by using a 't' test. (1973) and Sidhu and Grewal (1980). It is obvious from Table II that with the exception of jumpers, athletes of different activity groups in Group C had significantly delayed onset of menstruation, expecially ball game players and throwers.…”

“…Further, Malina et al (1978) noted that college athletes attained menarche significantly later than non-athletes and various groups of national and Olympic athletes attained menarche significantly later than high school and college athletes. Sidhu and Grewal (1980) In this study, an attempt has been made to determine whether menarcheal age of Nigerian women athletes differs from that of non-athletes. This would afford an understanding of the probable influence of physical exercise on the menarcheal age.…”

A Comparison of Body Composition between Eumenorrheic and Amenorrheic Adolescent Cross-Country Runners

“…For example, data from a review (Malina, 1985) of seventeen studies found that menarche occured later in athletes compared to the general population, suggesting that training delays menarche. In addition, studies by Frisch, et al (1981) and Sidhu and Grewal (1980) found menarchal age occurred later among athletes who began training before menarche as compared to athletes who began training after menarche.…”

“…To further this point, studies (Frisch, et al, 1981;Sidhu and Grewal, 1980) indicate later mean menarchal ages among athletes who began training before menarche as compared to athletes who began training after menarche. It is not surprising that menarche is also significantly related to skeletal maturity (Tanner, 1962;Malina, 1978), but the results of these studies and the other studies noted illustrate how highly complex the association between menarche and amenorrhea can be.…”
