Body Composition of Elite, Eumenorrheic and Amenorrheic, Adolescent Cross-Country Runners

Abstract: The purpose of the study was to investigate the seasonal relationship of athletic amenorrhea and body composition in elite, adolescent, cross-country runners. The participants consisted of 28 female adolescent cross-country runners (mean age +/- SD = 15.4 +/- 1.5 years); 17 eumenorrheics and 11 amenorrheics. The participants' body composition was measured pre- and postseason using dual-energy X-ray Absorptiometer (DXA). The eumenorrheics' postseason BMD was significantly greater than the amenorrheics' postseas… Show more

“…34 Sources of data for earlier studies of athletes in specific sports are in Boileau et al 47,48 and Malina et al 49 ; more recent sources of data for track and field athletes are in Malina. 50 Additional data are from Barrack et al, 51 Bauer et al, 52 Bonis et al, 53 D'Alessandro et al, 54 Nickols-Richardson et al, 55 Nurmi-Lawton et al, 56 50 Additional data are from Gurd and Klentrou, 58 Jürimäe, 59 Juzwiak et al, 60 Roemmich and Sinning, 61,62 and Tahara et al 63 overall pattern in Figures 2 and 4 generally follows the sample for female athletes in a variety of sports.…”

“…The body composition of adult athletes in a variety of sports has been the focus of several reviews. 19,41,[44][45][46] Estimates of % Fat in athletes 9 to 18 years of age in a variety of sports are shown relative to the mean trend for the general population in Figure 2 for girls 33,34,[47][48][49][50][51][52][53][54][55][56][57] and Figure 3 for boys. 33,34,[47][48][49][58][59][60][61][62][63] The reference data for the general population of youth and the majority of data points for athletes (means) are based on densitometry.…”

“…Athletes with longstanding functional hypothalamic amenorrhoea have been shown to benefit less from the osteogenic effects of exercise (Ackerman et al, 2012;Bonis, Loftin, Speaker, & Kontos, 2009). Even subtle alterations in the oestrogen/progesterone imbalance (e.g., regular menstruation but alterations in luteinising hormone), as seen in subclinical ovulatory disturbances, may adversely impact bone, particularly at trabecular-bone-dominant sites, such as the spine (Li, Hitchcock, Barr, Yu, & Prior, 2014).…”

“…"9,10 Previous studies indicate that runners and participants in other "lean-build" sports have a 25.8e26.7% prevalence of menstrual irregularity and reduced BMD. 10,11,15 Maximizing bone density accrual during adolescence is essential, yet only 29e38% of Division I and III college female athletes, 31.5% of female university students, and 7.5% of junior high and high school females are aware of the link between oligo/amenorrhea and osteoporosis. 16e18 To date there are no published data evaluating high school athletes' perceptions of the desirability of oligo/amenorrhea, their knowledge of the connection between menstrual status and BMD, and the association between menstrual status and knowledge and attitudes.…”
