Text: In the training group : a) maximal oxygen uptake (VO2max) increased from 58. 1 + / - 4. 5 mL x kg (-1) x min (-1) to 64. 3 + / - 3. 9 mL x kg (-1) x min (-1) (P < 0. 01) ; b) lactate threshold improved from 47. 8 + / - 5. 3 mL x kg (-1) x min (-1) to 55. 4 + / - 4. 1 mL x kg (-1) x min (-1) (P < 0. 01) ; c) running economy was also improved by 6. 7 % (P < 0. 05) ; d) distance covered during a match increased by 20 % in the training group (P < 0. 01) ; e) number of sprints increased by 100 % (P < 0. 01) ; f) number of involvements with the ball increased by 24 % (P < 0. 05) ; g) the average work intensity during a soccer match, measured as percent of maximal heart rate, was enhanced from 82. 7 + / - 3. 4 % to 85. 6 + / - 3. 1 % (P < 0. 05) ; and h) no changes were found in maximal vertical jumping height, strength, speed, kicking velocity, kicking precision, or quality of passes after the training period.
