  predictions of skeletal muscle mass nor dual-energy X-ray 
  absorptiometry provides detailed information on the size of 
  speciﬁc individual muscles. Given the known importance of 
  muscle size as a determinant of muscular strength (9–11), pro- 
  nounced muscle size seems likely to be critical to extreme 
  the speciﬁc muscle size of 
  human strength; however, 
  extremely strong individuals remains unknown. Similarly, a 
  large moment arm (e.g., of the patella tendon at the knee joint) 
  could contribute to the expression of high muscular strength 
  (10, 12), and a large tendon may mitigate the mechanical stress 
  it experiences with very high muscular loads, and therefore, 
  these characteristics may also be expected in individuals 
  selected for exceptional strength. 
  
  Overview 
  
  The WSM reported for a single test session that involved 
  the following assessments (listed in order): axial T1 weighted 
  3.0-T MRI scans from T12 to the lateral malleolus [to assess 
  muscle size throughout the lower body (left and right sides)], 
  axial and sagittal T1-weighted MRI scans of both knees [to 
  assess patellar tendon cross-sectional area (CSA) and patellar 
  tendon moment arm], maximum countermovement jumps 
  (CMJ), and maximum isometric midthigh pulls (IMTPs). The 
  muscle size, patellar tendon CSA, and patellar tendon 
  moment arm of the WSM were compared with various popu- 
  lations measured within our laboratory, as indicated in 
  Table 1, alongside participant descriptives (10, 11, 13–15). In 
  addition, the IMTP and CMJ measures were compared with 
  existing published literature (included studies are summar- 
  ized in Supplemental Materials 1 and 2, alongside participant 
  descriptives).
