text: In this paper, we present the ﬁndings from a unique op- 
  portunity to examine the laboratory function, muscle size, 
  and distribution of muscle mass, as well as patellar tendon 
  size and moment arm, of a World’s Strongest Man and dead- 
  lift champion (WSM) in comparison with existing data on 
  untrained individuals, power athletes (100-m-track sprint- 
  ers), and long-term resistance-trained populations that we 
  have assessed previously (10, 11, 13–15). 
  
  MRI Measurement of Muscle Tendon Unit Morphology 
  and Moment Arm 
  MATERIALS AND METHODS 
  
  Participant 
  
  The WSM’s achievements included one World’s Strongest 
  Man title (14 mo prior to measurement), ﬁve Britain’s 
  Strongest Man titles (the most recent 6 mo prior to measure- 
  ment), twice being World Deadlift Champion and Deadlift 
  World Record holder (500 kg; at the time of measurement), 
  and second place at Europe’s Strongest Man. Prior to agreeing 
  to participate, the purpose of the research study and the test- 
  ing procedures were explained to the participant along with 
  the risks and beneﬁts of taking part. The participant gave his 
  written informed consent to participate in the study that was 
  approved by the Loughborough University Ethical Advisory 
  Committee (Ethics Number R18-P090). Included in the writ- 
  ten consent was a statement providing permission for publi- 
  cation of the collected data and the likelihood that their 
  identity may be evident based on their achievements and 
  characteristics, despite anonymization.
