Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Research hypotheses:
this study will test the following null hypothesis: (Vo2max calculator) application will not have criterion validity in estimating VO2max values in the elderly population.
Research question:
Is the Smartphone application (VO2max calculator) considered a valid tool for estimating accurate values of VO2max in the elderly population in comparison to the golden standard method?
