Abstract
Abstract. Although combination of physical activity with supplementation has being investigated
on its effects in maintaining and enhancing bone health, however little is known about the
effectiveness of combination of aerobic dance exercise and honey supplementation on bone
metabolism markers and muscular strength in women. The aim of this study was to investigate the
effects of combined aerobic dance exercise and honey supplementation on bone metabolism and
muscular strength in women. Forty four subjects. healthy sedentary women (25-40 year-old) were
age and weight matched, and subsequently being assigned into four groups with n=ll per group:
Control group (C), honey supplementation group (H), aerobic dance exercise group (Ex) and
combined aerobic dance exercise with honey supplementation group (HEx). Aerobic dance
exercise was carried out for one hour per session, three times per week for eight weeks. Honey
drink was consumed by H and HEx groups, in a dosage of 20g of honey diluted in 300m! of plain
water, for 7 days per week for a total of 8 weeks duration. In HEx group, the subjects were
required to consume honey drink 30 minutes before performing exercise on the exercise days.
Before and after 8 weeks of experimental period, subjects' right lower limb muscular strength
were measured with knee extension and flexion isokinetic peak torque at 180 and 300 degree per
second. Meanwhile, blood samples were taken in order to determine the concentrations of serum
total calcium, osteocalcin (bone formation marker), serum C-terminal telopeptide of type I
collagen (ICTP) (bone resorption marker), and parathyroid hormone (PTH). At the end of 8
weeks of experimental period, combination of aerobic dance exercise with honey supplementation
(HEx) exhibited more discemable beneficial effects on lower limb peak torque compared to the
other three Ex, H and C groups. Regarding bone metabolism, the percentage of increment in I CTP,
a bone resorption marker, and PTH concentrations in HEx group were the lowest compared to the
other experimental groups. The results of present study suggest that combination of aerobic
dance exercise and honey supplementation may elicit effects on reducing the increment in bone
resorption, and more beneficial effects on lower limb muscular strength compared to aerobic
dance exercise or honey supplementation alone in sedentary women.
