Effects Of Aerobic Exercises On Bone-Specific Alkaline Phosphatase And Pyridinoline As Markers Of Bone Turnover Among Sedentary Urban-Dwelling Women At Post-Menopause

ABSTRACT

The aim of this study is to determine the effects of aerobic exercises on bone-specific alkaline

phosphatase and pyridinoline among sedentary women at post-menopause. Menopause has been

linked to increase bone turnover, which could lead to osteoporosis and consequently, bone

fracture. However, exercises are more desirable in management and prevention of osteoporosis.

This study was quasi-experimental involving 20 participants’ sedentary women at postmenopause

selected using purposive sampling technique and randomly assigned to two groups of

10 participants each. Aerobic group engaged in exercise training using bicycle ergometer for 30

minutes thrice a week for 6 weeks while the Sedentary group (control) did not engage in any

exercise for that 6 weeks. All participants were within the age range of 45-60 years of age.

Before the exercise interventions, the vital signs, anthropometric measurements (Height, weight,

body mass index), percentage body fat (%Bfat), serum concentration BALP and urine

concentration PYD of all participants in both groups were obtained. After 6 weeks all parameters

above were also assessed. Data collected were analysed using t-test and Pearson product moment

correlation with alpha set at p
