Shortcomings of Body Composition Assessments, and Fitness-Related Applications of Mindfulness and Meditation
The Stronger By Science Podcast
How Do You Assess Body Composition?
Most methods of assessing body composition work pretty well for groups. There can still be some small group level errors, but they tend to be like 2 or 3% at most. Some of them work better than others; DEXA is just categorically better than BIA. But you know, for assessing groups of people, they all get the job done.
In today's episode, Greg and Eric pat themselves on the back for breaking the 100 episode barrier, in addition to sharing their picks for Fat Bear Week 2022. After that, Greg encroaches on Eric’s territory with a segment about body composition assessments. In the segment, Greg discusses what common body composition devices actually measure, how accurate (or inaccurate) they are for individuals (rather than groups), and some better strategies for monitoring progress toward fitness goals. After that, Eric steers others toward the Road to Enlightenment with a segment on the fitness-related applications of mindfulness and meditation. He specifically looks at the research evaluating mindfulness-based interventions for mental fatigue, sleep, pain management, and eating behaviors. Eric also discusses scenarios in which mindfulness-based interventions might be contraindicated, and provides some resources for people who want to give meditation or other mindfulness-based interventions a shot.
