“…Lower intensity and higher volume used in CA promote a more prolonged effect on force production. However, more experienced athletes bene t from higher loads and longer rest intervals in RFD 8, 34 . Although the EP did not present a signi cant improvement for the group of rowers, the study points to an increase in the total 3-minute distance covered and in the mean output power, which suggests ergonomic e ciency, in addition to the individual analyses showing more elevated EP values for more experienced rowers after CA intervention 11 .…”

This study aimed to investigate the impact of post-activation potentiation enhancement (PAPE) on parameters of 3-minute all-out test (3MT) on non-motorized tethered running performance by applying the concept of complex networks for integrative analysis. Ten recreational sports athletes where submitted to anthropometric tests, 1RM ramp, and 3MT trials (PAPE and CONTROL conditions) across five separate test sessions. The conditioning activity model applied was two series of six back squats at 60% 1RM. Based on the complex network, graphs were constructed for each scenario (CONTROL and PAPE) to investigate the Degree, Eigenvector, Pagerank, and Betweenness centrality metrics. PAPE scenario shows greater centrality of anthropometrics and conditioning parameters related to aerobic efficiency, ranking among the top-five classified nodes. Paired Student t-test (p ≤ 0.05) results for 3MT showed differences between two conditions (PAPE vs. CONTROL) for values of EP-W (407.83 ± 119.30; 539.33 ± 177.10) and rEP-W.kg-1(5.38 ± 1.70; 6.91 ± 2.00), and mechanical parameters in absolute and relativized values of peak output power, mean output power, peak force, and mean force. Our results suggest that PAPE modifies the graphs' configuration, raising the network density, and may increase the neuromuscular functions and running economy. In addition, it seems to optimize the activation of aerobic and anaerobic metabolism.

“…One such strategy is postactivation performance enhancement (PAPE) (5)(6)(7). PAPE has been extensively studied in the past two decades, particularly in relation to land-based activities like jumping (8,9) and sprinting (10,11). For these types of activities, it is well-established that performing pre-activation activities involving heavy weightlifting a few minutes prior to explosive muscle actions leads to improved performance (10)(11)(12)(13).…”

“…PAPE has been extensively studied in the past two decades, particularly in relation to land-based activities like jumping (8,9) and sprinting (10,11). For these types of activities, it is well-established that performing pre-activation activities involving heavy weightlifting a few minutes prior to explosive muscle actions leads to improved performance (10)(11)(12)(13). The magnitude of this effect can be influenced by several factors, including strength, sex, level of training, and the protocol of the pre-activation activity (including the amount of resistance, number of sets, and time between the pre-activation and the potentiated action) (7,14).…”

Our aim was to investigate if using a warm-up routine that included parachute-resisted sprints with large hand-paddles improves 50 m freestyle performance in trained collegiate swimmers. Twelve swimmers (23.9 ± 2.2 years, 179 ± 7 cm, 77.1 ± 10.6 kg) participated in the study and completed two 50-m freestyle races, each preceded by a different warm-up routine, either control (CON) or experimental (EXP). The warm-up routines consisted of 500 m of swimming at self-selected speed, followed by four 10 s sprints with 1 min rest intervals. During EXP, sprints were performed using large hand-paddles and a swimming parachute, while during CON, sprints were performed freely. Performance and technique were assessed during the 50 m freestyle races. We found no significant differences in 25- and 50 m performance times (CON: 12.6 ± 0.8 vs. EXP: 12.5 ± 0.8 s, ES = 0.125; and CON: 26.8 ± 1.6 vs. EXP: 26.7 ± 1.7 s, ES = 0.06, respectively) between the two conditions. Mean stroke length (CON: 2.04 ± 0.21 vs. EXP: 2.02 ± 0.22 m·cycle−1, ES = 0.09), stroke frequency (CON: 55.4 ± 5.3 vs. EXP: 56.3 ± 5.2 cycles s−1, ES = 0.17), and propulsive time (CON: 0.62 ± 0.07 vs. EXP: 0.61 ± 0.06 s, ES = 0.15) were also not different between conditions. It is possible that the CON warm-up routine induced the priming effects that lead to PAPE, or that the EXP warm-up routine primed the athletes further but also induced greater fatigue, resulting in no significant effects on swimming performance. Our findings suggest that parachute-resisted sprints with hand-paddles during warm-up do not enhance 50 m freestyle swimming performance in trained collegiate swimmers. Coaches and practitioners should consider exploring different warm-up protocols to identify what works best for their athletes.
