8. Meaningful Difference, Individual Response & Study Design (Concepts, Approaches, Simulations)
Channel: Christoph Schneider
Date: 2021-12-07

In this session, I will introduce the concepts of meaningful differences, individual response and single-case research design in the context of athlete monitoring. The basic concepts and approaches are presented, examples are given from the literature, and simulations are used to illustrate the effect of measurement error on observed (individual) response and in which way repeated measures can help. 

Content:
1. What is a Meaningful Difference? 
2. Individual Response 
3. Study Design 
4. Take-Home Message

The spreadsheet for performing the simulations tasks will be made available on the OSF Project webpage (link below).

This video is part of the seminar ‘Monitoring, Training Prescription & Recovery Science’ that I teach/ taught in the winter semester 2021/22 in the M.Sc. program ‘Sport & Exercise Sciences for Health & Performance’ at the Ruhr University Bochum, Germany.
