1RM one-repetition maximum, NR not reported, – not tested, All players combined across all positions, BB Barbell
^aTotal sample size (all positions combined) was reported rather than independently for each position
^bAge provided categorically as under 15 years instead of being reported as mean ± standard deviation
^cAge provided categorically as under 16 years instead of being reported as mean ± standard deviation
^dAge provided categorically as under 17 years instead of being reported as mean ± standard deviation
^eAge provided categorically as under 18 years instead of being reported as mean ± standard deviation
^fSample size for each test varied so data are reported separately for Bench press 1RM (n = 31), Back squat 1RM (n = 30), Prone row 1RM (n = 31), 40-m (n = 178) in order
