Robinson
et al. 13

♀, collegiate gymnasts (n =
21, age 16.21.7 years)
runners (n = 20, 14.41.7
years), and nonathletic
college women (n = 19,
13.01.2 years), No BMI
data.

Lumbar spine BMD was lower in
runners compared with both
gymnasts and controls.
Whole body BMD was lower in
runners compared with gymnasts
and controls.

Taaffe
et al. 14

Runners showed significantly lower
BMD in femoral neck, lumbar spine
but not in whole body BMD.

college level athletes

Runners had lowest lumbar spine
and pelvis BMD when compared to

Emslander
et al. 17

No significant difference was shown
in total body, spine and proximal
femoral BMD among runners,
swimmers and control groups.

Duncan
et al. 18

Areal BMD estimation was
performed on mid-third femur.
Runners had higher BMD only than
cyclist. No difference was shown
among groups of runners, swimmers,
triathlete and controls.

There is no significant difference
among amenorrheic runners,
eumenorrheic runners, and controls
in lumbar BMD.

After adjusting for lean tissue mass

in BMC was detected.
