- Knee muscles isokinetic evaluation in short distance elite swimmers: A comparison between symmetric and asymmetric swimming styles(2011) SECCHI, Leonardo L. B.; MURATT, Mavi Diehl; CIOLAC, Emmanuel G.; GREVE, Julia M. D.Objective: To compare knee extension-flexion isokinetic performance between elite swimmers of simultaneous (SS butterfly and breaststroke) and alternated swimming (AS - front crawl and backstroke) styles. Method: Nineteen short distance elite swimmers (50 m, 100 m and 200 m events), divided into SS (n = 7; 23.3 +/- 5.6 years) and AS (n = 12; 22.6 +/- 1.4 years) were tested for knee extension-flexion isokinetic strength at 60 degrees/s (4 repetitions) and endurance at 300 degrees/s (30 repetitions). Results: There were no significant differences between groups or legs for concentric knee extension and flexion variables. However, the agonist/antagonist (HQ) ratio was lower (p = 0.032) in AS than SS group for both legs. Conclusion: These results indicate the need for training programs to improve strength balance between hamstrings and quadriceps muscles in short distance elite swimmers.
conferenceObject Isokinetic Evaluation in Knee Muscles Elite Swimmers: A Comparison between Symmetric and Asymmetric Swimming Styles(2012) SECCHI, Leonardo Luiz B.; CIOLAC, Emmanuel Gomes; MURATT, Mavi Diehl; GREVE, Julia Maria D'Andrea- The effects of motor learning on clinical isokinetic performance of postmenopausal women(2011) BRECH, Guilherme Carlos; CIOLAC, Emmanuel Gomes; SECCHI, Leonardo Luiz Barretti; ALONSO, Angelica Castilho; GREVE, Julia Maria D'AndreaObjective: To analyze the effects of motor learning on knee extension-flexion isokinetic performance during clinical isokinetic evaluation of postmenopausal women. Methods: One-hundred and twenty postmenopausal women (60.3 +/- 3.2 years; BMI = 27.6 +/- 4.7 kg/m(2)) without knee pain or injury and that never underwent isokinetic testing, were submitted to two bilateral knee extension-flexion (concentric-concentric) isokinetic evaluation (5 repetitions) at 60 /s (Biodex (TM) Multi-joint System 3 dynamometer). The tests were first performed in the dominant leg, with a 1-min recovery between them, and after a standardized warm-up that included 3 submaximal isokinetic repetitions. The same procedure was repeated in the non-dominant leg. Peak torque (PTQ) was adjusted for body weight (PTQ/BW), total work (TW), coefficient of variation (CV) and agonist/antagonist (agon/antag) ratio was compared between tests. Results: Subjects showed greater levels (P < 0.001) of PTQ PTQ/BW and TW, and lower CV levels (P < 0.01) in test 2 of both legs. Agon/antag ratio did not change significantly between tests. Conclusions: PTQ PTQ/BW, TW and CV improved in the second knee extension flexion isokinetic testing of postmenopausal women. The results suggests that performing two tests, even with a short period of recovery between them, could be considered for reducing motor learning effects on clinical isokinetic evaluation of knee joint in postmenopausal women.
