The basal metabolic rate (BMR), defined as the energy required for performing vital body functions at rest, is the largest contributor to energy expenditure and is a major contributor to energy balance. Therefore, accurately estimating BMR is critical for developing rigorous obesity prevention and control strategies. The Timed Forearm Plank Test, also known as the Prone Bridge Test, is a simple and cost effective fitness test of core muscle strength which can be easily self-administered. It is also an excellent technique for strengthening the core muscles. Very few studies have studied the relationship of Basal Metabolic Rate and isometric muscle endurance which is known to be less in the female population. Therefore the need to establish whether there is a significant relationship between the BMR and isometric core muscle endurance in adult females.
