The purpose of this study was to examine the effect of carbohydrate loading
(CHO) on physiologic and performance variables in seven moderately trained
females (aged 30.9 ± 9.6 years; VO2max 51.8 ± 2.3 ml/kg/minute) during the
follicular and luteal menstrual cycle phases. Participants completed a 60 minute
treadmill run at 70% VO2max followed by a timed run to exhaustion at 80%
VO2max under four conditions: (1) follicular phase, CHO loading (F/CHO); (2)
follicular phase, normal mixed diet (F/NMD); (3) luteal phase, CHO loading
(L/CHO); (4) luteal phase, normal mixed diet (L/NMD). CHO loading was
accomplished using a modified regime and a tapered running program. Performance
time to volitional exhaustion at 80% VO2max was significantly increased in L/CHO
over L/NMD (p
