Description
Geranda Slager, PhD, is a physiotherapist and human movement scientist with a continuing focus on clinical measurement and muscle strength. She is a lecturer and senior researcher in the Physiotherapy programme at Hanze University of Applied Sciences, Groningen.
In her research, she collaborates with senior researcher Martine Sealy, PhD, and Marianne Nieuwenhuis, PhD, from the research group Healthy Ageing, Allied Health Care and Nursing, Hanze University of Applied Sciences Groningen and the Burn Centre, Martini Hospital in Groningen, the Netherlands.
In recent years, her research has focused on simplifying bioelectrical impedance analysis (BIA) measurements for assessing body composition and estimating muscle mass, fat mass, and fat-free mass. BIA measurements are generally performed according to standardized protocols with a number of specific preconditions. Her research investigates whether these measurements remain valid when such preconditions are not met. This includes examining the effects of, among other factors, placing electrodes at alternative locations, consuming large amounts of water, measuring with a full bladder, or performing measurements in different body positions.
In addition, she investigates the effects of increased body weight on the outcomes of functional muscle strength tests by using weighted vests ranging from 5 to 60 kg. Her research includes functional tests such as the Five Times Sit-to-Stand Test (5TSTT) and the 30-Second Sit-to-Stand Test. One of the aims is to gain insight into the level of (relative) muscle strength required by people with obesity to perform the Five Times Sit-to-Stand Test within the normative time.
