In addition, therewas a significant difference within groups in FCR, VO 2 peak, VO 2 VT1, VO 2 VT2, VT2 speed in both groups compared pre- and post-training. A significant difference was noted in maximum speed reached in PG and VT1 and VT2 inclination in NPG in the comparison between groups (Table 4). Skeletal muscle function The evaluation of the muscle strength parameters within groups, compared pre- and post-training, showed a significant improvement. In a comparison made between the groups, no significant difference could be found (Table 5).
