Predictive Accuracy Of The Nelson Equation Via Bodpod Compared To Commonly Used Equations To Estimate Resting Metabolic Rate In Adults, Bryndan Lindsey, Daniel Shookster, Joel Martin, Nelson Cortes
International Journal of Exercise Science
International Journal of Exercise Science 14(2): 1166-1177, 2021. Indirect calorimetry (IC) is considered the gold standard for assessing resting metabolic rate (RMR). However, many people do not have access to IC devices and use prediction equations for RMR estimation. Equations using fat free mass (FFM) as a predictor have been developed to estimate RMR, as a strong relationship exists between FFM and RMR. One such equation is the Nelson equation which is used by the BodPod (BP). Yet, there is limited evidence whether the Nelson equation is superior to other common equations to predict RMR. To examine the agreement between …

Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett
International Journal of Aquatic Research and Education
A person, usually a child or young adult, dies by drowning every 90 seconds around the planet. Most drowning prevention initiatives do not assess the efficacy of the intervention. In this study, thirteen- to fourteen-year-olds had their level of water safety knowledge (covering cold shock, rips and tides) assessed before, just after, and 3-6 months after one, 25-minute water safety lesson on these topics. We evaluated the knowledge gained and retained on water safety “awareness” (i.e., knowledge of risks) and “confidence” in terms of knowing what to do in an emergency. The results demonstrated that the lesson significantly increased water …
