Figure 1
From: Intensity-dependent cardiopulmonary response during and after strength training
shows the timeline of measurements (A) execution and equipment (B). (A) The three load conditions (3 sets of 10 repetitions interspaced by a resting period of 4 min; intensities: 50%, 62.5% and 75% of 3-RM) were performed on separate days with a break lasting at least 5 days to ensure adequate recovery. The order of sessions 2 and 3 was randomized. On the first day, the individual 3-repetition maximum (3 RM) in the smith-machine back squat was determined. (B) Resting and post-exercise period = upright in a smith machine; exercise periods = ten repetitions within 60 s; Execution = 2 s descend, 2 s ascend and 2 s hold at the top; Ventilation and hemodynamic were recorded continuously; blood pressure measurement (only in post-exercise period): immediately after exercise, 1:30 min after exercise, and 2:30 after exercise; Blood pressure measurements during strength training sessions were not taken during the standardized strength training sessions because of interference in the repetition sequence and for safety reasons.
