| Popis: | The “zero point” method allows for lower intensities for an exercise session without impairing the total training volume. This study aimed to compare the effects of the “zero point” versus the traditional method on muscle responses and muscle damage in trained men. Fifteen experienced men (age: 27.7 ± 6.4 years; body mass: 78.4 ± 11.4 kg; height: 174.8 ± 4.9 cm; experience: 5.86 ± 4.7 years; relative bench press strength: 1.38 ± 0.17 kg·kg−1) were subjected to two exercise protocols in a randomized order and separated by a week. The traditional and “zero point” methods were applied in the bench press, with loads of 70% and 50% of one repetition maximum (1RM), respectively, for 10 sets until concentric failure, with 3-min intervals between sets. The zero point method displayed a higher number of repetitions and time under tension than the traditional method, with no difference in the total training volume, echo intensity, algometry, lactate, and myoglobin. For the muscle thickness, no differences between the groups were presented, except for the deltoid muscle thickness, in which a higher post-training volume was observed compared to traditional training. The “zero point” method increases the demand on the deltoid muscles in the bench press exercise, but not on the pectoralis and triceps brachii. |
