Effects of Chocolate Malt Drink Consumption Combined with Aerobic Dance Exercise on Blood Bone Metabolism Markers, Antioxidant Enzymes and Aerobic Capacity in Young Females

Abstract

Purpose: The aim of this study was to investigate the effects of combined aerobic dance exer- cise and chocolate malt drink consumption on bone metabolism markers, antioxidant enzymes and aerobic capacity in young females. Methods: Forty four physically healthy females (19-25 years old) were age and body mass matched and subsequently being assigned into four groups with n=11 per group: Control group (C), Chocolate malt drink group (Cmd), aerobic dance exercise group (Ex) and combined aero- bic dance exercise and chocolate malt drink group (CmdEx). Participants' anthropometry and aerobic capacity were measured. Meanwhile, blood samples were taken in order to determine the concentrations of serum total calcium, serum osteocalcin and serum alkaline phosphatase (ALP) (bone formation marker), serum C-terminal telopeptide of type 1 collagen (1CTP) (bone resorption marker) and antioxidant enzyme activities, i.e. Glutathione peroxidase (GPx) and Superoxide dismutase (SOD). Results: At the end of 8 weeks of the intervention period, the percentage of increment in se- rum osteocalcin was the highest in CmdEx group compared to the other experimental groups. Meanwhile, significant increased in glutathione peroxidase were observed in Ex (p<0.05) and CmdEx (p<0.01) groups after 8 weeks of intervention period. Additionally, the percent- age changes in glutathione peroxidase and superoxide dismutase activity were the highest in CmdEx group compared to other groups. There were also significant increases in aerobic ca- pacity in Ex and CmdEx groups. Conclusions: The present study found that generally aerobic dance exercise alone and aerobic dance exercise combined with the consumption of chocolate malt drink elicited more benefi- cial effects on bone turnover, antioxidant enzyme activities and aerobic capacity compared to chocolate malt drink consumption alone or sedentary without chocolate malt drink consump- tion in young females.
