- Heart rate response to exercise and cardiorespiratory fitness of young women at high familial risk for hypertension: effects of interval vs continuous training(2011) CIOLAC, Emmanuel G.; BOCCHI, Edimar A.; GREVE, Julia M. D.; GUIMARAES, Guilherme V.Exercise training is an effective intervention for treating and preventing hypertension, but its effects on heart rate (HR) response to exercise and cardiorespiratory fitness (CRF) of non-hypertensive offspring of hypertensive parents (FH+) has not been studied. We compared the effects of three times per week equal-volume high-intensity aerobic interval (AIT) and continuous moderate-intensity exercise (CME) on HR response to exercise and CRF of FH+. Forty-four young FH+ women (25.0 +/- 4.4 years) randomized to control (CON; n = 12), AIT (80-90% of VO2MAX; n = 16), or CME (50-60% of VO2MAX; n = 16) performed a graded exercise test (GXT) before and after 16 weeks of follow-up to evaluate HR response to exercise and several parameters of CRF. Resting, maximal, and reserve HR did not change after the follow-up in all groups. HR recovery (difference between HRMAX and HR at 1 minute of GXT recovery phase) improved only after AIT (11.8 +/- 4.9 vs. 20.6 +/- 5.8 bpm, p < 0.01). Both exercise programmes were effective for improving CRF parameters, but AIT was more effective than CME for improving oxygen consumption at the respiratory compensation point (VO2RCP; 22.1% vs. 8.8%, p = 0.008) and maximal effort (VO2MAX; 15.8% vs. 8.0%, p = 0.036), as well as tolerance time (TT) to reach anaerobic threshold (TTAT; 62.0 vs. 37.7, p = 0.048), TTRCP (49.3 vs. 32.9, p = 0.032), and TTMAX (38.9 vs. 29.2, p = 0.042). Exercise intensity was an important factor in improving HR recovery and CRF of FH+women. These findings may have important implications for designing exercise-training programmes for the prevention of an inherited hypertensive disorder.
- 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.

D.; CIOLAC, Emmanuel G.- 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.
article 8 Citação(ões) na Scopus Hemodynamic response in one session of strength exercise with and without electrostimulation in heart failure patients: A randomized controlled trial(2011) CARVALHO, Vitor Oliveira; ROQUE, Jean Marcelo; BOCCHI, Edimar Alcides; CIOLAC, Emmanuel Gomes; GUIMARAES, Guilherme VeigaBackground: Studies have investigated the influence of neuromuscular electrostimulation on the exercise/muscle capacity of patients with heart failure (HF), but the hemodynamic overload has never been investigated. The aim of our study was to evaluate the heart rate (HR), systolic and diastolic blood pressures in one session of strength exercises with and without neuromuscular electrostimulation (quadriceps) in HF patients and in healthy subjects. Methods: Ten (50% male) HF patients and healthy subjects performed three sets of eight repetitions with and without neuromuscular electrostimulation randomly, with one week between sessions. Throughout, electromyography was performed to guarantee the electrostimulation was effective. The hemodynamic variables were measured at rest, again immediately after the end of each set of exercises, and during the recovery period. Results: Systolic and diastolic blood pressures did not change during each set of exercises among either the HF patients or the controls. Without electrostimulation: among the controls, the HR corresponding to the first (85 +/- 13 bpm, p = 0.002), second (84 +/- 10 bpm, p < 0.001), third (89 +/- 17, p < 0.001) sets and recuperation (83 +/- 16 bpm, p = 0.012) were different compared to the resting HR (77 bpm). Moreover, the recuperation was different to the third set (0.018). Among HF patients, the HR corresponding to the first (84 +/- 9 bpm, p = 0.041) and third (84 +/- 10 bpm, p = 0.036) sets were different compared to the resting HR (80 +/- 7 bpm), but this increase of 4 bpm is clinically irrelevant to HF. With electrostimulation: among the controls, the HR corresponding to the third set (84 +/- 9 bpm) was different compared to the resting HR (80 +/- 7 bmp, p = 0.016). Among HF patients, there were no statistical differences between the sets. The procedure was well tolerated and no subjects reported muscle pain after 24 hours. Conclusions: One session of strength exercises with and without neuromuscular electrostimulation does not promote a hemodynamic overload in HF patients.
