Exercise volume and timing does not affect body composition of elderly in Singapore
Background: Singapore has one of the fastest aging population in the world. Changes in body composition of aging people are considered one of the major causes of chronic diseases like osteoporosis and obesity (Kyle, Morabia, Schutz, & Pichard, 2004). Current guidelines by organisations lik...

| Summary: | Background: Singapore has one of the fastest aging population in the world. Changes in
body composition of aging people are considered one of the major causes of chronic diseases
like osteoporosis and obesity (Kyle, Morabia, Schutz, & Pichard, 2004). Current guidelines
by organisations like World Health Organisation (WHO) have neglected the possible benefits
of exercise volume and timing on body composition despite significant findings by other
researchers.
Purpose: The primary objective is to investigate the relationship between exercise volume
and body composition of elderly in Singapore, while the secondary objective is to investigate
the difference in body composition between exercise timings.
Methods: A cross-sectional study design was employed. 37 healthy elderly aged between 60
79 was recruited to the laboratory to have their body composition measured with InBody 230,
while their physical activity was assessed using International Physical Activity Questionnaire
(IPAQ) with an additional question for exercise timing. Data obtained were analysed using
statistical analysis software (SPSS v.23; SPSS Inc.).
Results: There was no significant correlation between exercise volume and body
composition: MM, p = 0.123; FM, p = 0.105; BMI, p = 0.662; BMD, p = 0.857. There was no
significant difference in body composition between exercise timings: MM, p = 0.733; FM, p =
0.768; BMI, p = 0.098; BMD, p = 0.600.
Conclusion: Before more conclusive evidence supporting the benefits of exercise volume or
timing is found, intervention strategies formulated to promote healthier body composition of
elderly should focus on other components of exercise habit, like type or intensity of exercise.
