Cardiovascular and exercise physiology

Purpose The study aim was to evaluate the maximum dynamic strength (MDS), mood levels, stress, and recovery during strength training in Paralympic powerlifting (PP). Methods The study involved 7 male PP athletes (41.0 ± 10.1 years; 84.7 ± 21.1 kg). MDS (one-repetition maximum [1RM] with bench press), stress/recovery (RESTQ-Sport), mood status (BRUMS), and resting heart rate (oximeter) were determined before and after a PP training mesocycle (4 weeks). The bench press training was performed with 5 sets of 5 repetitions (5 × 5) with 80–85% of 1RM in the 1^st week, 5 × 3 with 85–90% of 1RM in the 2^nd week, 5 × 1–3 with 90–95% of 1RM in the 3^rd week, and 5 × 5 with 40–70% of 1RM in the 4^th week. Results There was a significant increase in MDS (<i>p</i> < 0.001; effect size [ES]: 0.50). In the RESTQ-Sport scales, lack of energy (<i>p</i> < 0.022; ES: 1.30), success (<i>p</i> < 0.035; ES: 0.33), and sleep quality (<i>p</i> < 0.007; ES: 0.62) increased. The scales of general well-being (<i>p</i> < 0.012; ES: 2.18), interval disturbances (<i>p</i> < 0.021; ES: 3.14), personal acceptance, and self-regulation (<i>p</i> < 0.006; ES: 2.21) decreased. Regarding mood, the dimensions of tension (^p < 0.003; ES: 1.32), depression (<i>p</i> <; 0.001; ES: 5.00), anger (<i>p</i> <; 0.001; ES: 4.75), fatigue (<i>p</i> < 0.002; ES: 0.72), and confusion (<i>p</i> < 0.002; ES: 2.09) increased and the vigour decreased (<i>p</i> < 0.001; ES: 0.87). Conclusions The internal training load can be controlled by psychophysiological indicators in PP.
