TI  - Reliability of 1-repetition maximum estimation for upper and lower body muscular 
      strength measurement in untrained middle aged type 2 diabetic patients.
PG  - 267-73
AB  - PURPOSE: The 1-repetition maximum (1-RM) test is the gold standard test for 
      evaluating maximal dynamic strength of groups of muscles. However, safety of 
      actual 1-RM testing is questionable in clinical situations such as type 2 
      diabetes (T2D), where an estimated 1-RM test is preferred. It is unclear if 
      acceptable test retest reliability exists for the estimated 1-RM test in middle 
      aged T2D patients. This study examined the reliability of the estimated 1-RM 
      strength test in untrained middle aged T2D subjects. METHODS: Twenty five 
      untrained diabetic males (n=19) and females (n=6) aged 40.7+0.4 years 
      participated in the study. Participants undertook the first estimated 1-RM test 
      for five exercises namely supine bench press, leg press, lateral pull, leg 
      extension and seated biceps curls. A familiarisation session was provided three 
      to five days before the first test. 1-RM was estimated for all participants by 
      Brzycki 1-RM prediction equation. Another identical 1-RM estimation procedure 
      occurred one week after first test. Intraclass correlation coefficients (ICC), 
      paired t-test, standard error of measurement (SEM), Bland-Altman plots, and 
      estimation of 95% CI were used to assess reliability. RESULTS: Test-retest 
      reliability was excellent (ICC(2,1)=0.98-0.99) for all measurements with the 
      highest for leg extension (ICC(2,1)=0.99). The SEM was lowest for lateral pull 
      and leg extension exercises. Paired t-tests showed non-significant differences 
      between the means of 2 sessions across three of five exercises. CONCLUSIONS: The 
      study findings suggest that estimation of 1-RM is reliable for upper and lower 
      body muscular strength measurement in untrained middle aged T2D patients.
