Does duration of rest interval affect 1-Rm bench press test?

Bench press 1-RM test is a common assessment to measure maximal strength of the upper body musculatures. Most protocols recommend a rest period between the maximum contraction trials to avoid fatigue which may confound the assessment. Factors that influence fatigue are strength level and fatigue rec...
