“…In each trial, all the arm strokes performed within a 10-second interval were analyzed separately, 3,21 and we extracted the parameters that could influence impulse, a procedure similar to that adopted by Ugrinowitsch et al 23 and Andrade et al 24 The following biomechanical parameters were considered: • Minimum Force ( min F): the lowest force value found in propulsive action. It is the result of an intracycle variation of propulsive force 18 and was used to define the start of each stroke ( min F1, min F2, min F3 ...); expressed in N. • Peak Force ( peak F): the highest force value found in the stroke; expressed in N. • Mean Force ( mean F): mean force generated throughout the stroke; therefore, between two instants of min F ( min F1 and min F2, min F2 and min F3 ...); expressed in N. • Stroke duration (DUR): time elapsed between two instants of min F ( min F1 and min F2, min F2 and min F3 ...); expressed in milliseconds (ms).…”

Introduction: Propulsive force in swimming, represented through impulse, is related to performance. However, since the as different biomechanical parameters contribute to impulse generation, coaches have a difficult task when seeking for performance improvement. Objective: Identify the main components involved in impulse generation in the front crawl stroke. Methods: Fourteen swimmers underwent a 10-second all-out fully tethered swimming test. The following parameters were obtained from the force-time curve: minimum force, peak force, mean force, time to peak force, rate of force development and stroke duration. This stage was followed by a principal component analysis. Results: The principal component analysis showed that component 1, predominantly kinetic, was composed of peak force, mean force and rate of force development, and accounted for 49.25% of total impulse variation, while component 2, predominantly temporal, composed of minimum force, stroke duration, and time to peak force, represented 26.43%. Conclusion: Kinetic parameters (peak force, mean force, and rate of force development) are more closely associated with impulse augmentation and, hypothetically, with non-tethered swimming performance.

SummaryStudy aim: To evaluate the effect of power and muscle strength training on skin temperature and the performance of the vertical jump with countermovement (CMJ).Material and methods: The sample consisted of four male basketball athletes of the under-17 category (age: 15.75 ± 1.0 years). 48 hours after anthropometric evaluation and determination of the loads for 1 repetition maximum (1RM) in the leg extension exercise, the athletes were subjected, through crossover-type entrance, to power (PTP) and strength (STP) training protocols. The protocols consisted of three sets with loads of 60% and 90% of 1RM for PTP and STP, respectively. Thermographic images of the thighs were taken before and immediately after each training session.Results: There were significant differences in results between the two training protocols, with increased total repetitions (t = 13.481; p < 0.05) and total training volume (t = 15.944; p < 0.05) in the PTP, and increase in the % of 1RM (t = 33.903; p < 0.05) and rating of perceived exertion (t = 6.755; p < 0.05) in the STP. The skin temperature before and after PTP and STP showed no significant differences. In the post-STP, the CMJ presented significant reductions in height (t = 3.318; p < 0.05), flight time (t = 3.620; p < 0.05), velocity (t = 3.502; p < 0.05), and force (t = 4.381; p < 0.05). There were no significant differences in pre-and post-STP CMJ.Conclusions: Power and maximum strength training in the leg extension exercise performed until concentric failure appears to be a method that induces thermal stress on the skin. This training directly influenced the performance of the vertical jump after the stimulus.
