Resumo: | BacKGround: The swimming community has shown considerable interest in using dry-land warm-ups as a method of impacting perfor- mance. This study compared the effects of high-resistance pull-over and swimming warm-up in semi-tethered resisted swimming. MeThodS: an incremental-load semi-tethered swimming test was individually administered in 20 national-competitive swimmers to deter- mine the load maximizing swimming power. in different sessions, participants tested such a load 6 min after a swimming warm-up (SWu) or a dry-land warm-up (dlWu: 3 pull-over reps at 85% of the one-repetition maximum). Kinetic variables (velocity, force, acceleration, impulse, power rate of force development [rfd] and intra-cycle variation), were obtained with a linear encoder through trapezoidal integration regarding time. Kinematic variables (distance, time, stroke-rate and stroke-length), were obtained by video recordings. The differences between protocols were observed by paired-samples t-test (ANOVA). Pearson’s coefficient explored correlations between kinetics and kinematics variables; sig- nificance was set at P<0.05. reSulTS: dlWu increased rfd (34.52±16.55 vs. 31.29±13.70 N/s; Δ=9.35%) and stroke-rate (64.70±9.84 vs. 61.56±7.07 Hz; Δ=5.10%) compared to SWu, but decreased velocity, force, acceleration, impulse and power. during the incremental-load test velocity and power were higher than obtained after SWu (1.21±0.14 vs. 1.17±0.12 m/s; Δ=3.06%), (51.38±14.93 vs. 49.98±15.40 W; Δ=2.72%), suggesting enhance- ments prompted by the test itself. Correlations between stroke-length with impulse (r=0.76) and power (r=0.75) associated kinetics with kine- matics. CONCLUSIONS: Potentiation responses were present after the dry-land warm-up. However, swimmers may benefit more from submaximal prolonged conditioning activities such as resisted swimming rather than high-resistance dry-land sets to obtain performance enhancements. |
