title: Erratum.
abstract: In the article by Davis P, Wittekind A, and Beneke R, "Amateur Boxing: Activity Profile of Winners and Losers," in Int J Sport Physiol Perform. 8(1), pp. 84-91, the digit zero was inadvertently deleted from some of the figures in the tables. Table 1, Total punches, Round 1 winners should be 20.7 not 2.7, and Round 3 winners should be 20.3 not 2.3. Table 2, Air punches, Round 1 winners should be 10.1 not 1.1, and Round 3 losers should be 10.6 not 1.6. Table 2, Punches/min, Round 2 should be 20.2 not 2.2, and Round 1 losers should be 20.2 not 2.2. Table 4, 2-punch-combinations, Round 2 winners should be 10.4 not 1.4, and Round 3 winners should be 10.2 not 1.2. We apologize for the error.
