Respostas cardiorrespiratórias máximas e no limiar anaeróbio da corrida em piscina funda

Abstract

-Aquatic exercises provide numerous benefits to the health of their practitioners. To secure these benefits, it is essential to have proper prescriptions to the needs of each individual and, therefore, it is important to study the cardiorespiratory responses of different activities in this environment. Thus, the aim of this study was to compare the cardiorespiratory responses at the anaerobic threshold (AT) between maximal deep-water running (DWR) and maximal treadmill running (TMR). In addition, two methods of determining the AT (the heart rate deflection point [HRDP] and ventilatory method [VM]) are compared in the two evaluated protocols. Twelve young women performed the two maximal protocols. Two-factor ANOVA for repeated measures with a post-hoc Bonferroni test was used (α < 0.05). Significantly higher values of maximal heart rate (TMR: 33.7 ± 3.9; DWR: 22.5 ± 4.1 ml.kg ) and maximal oxygen uptake (TMR: 33.7 ± 3.9; DWR: 22.5 ± 4.1 ml.kg ) in TMR compared to the DWR were found. Furthermore, no significant differences were found between the methods for determining the AT (TMR: VM: 28.1 ± 5.3, HRDP: 26.6 ± 5.5 ml.kg ). The results indicate that a specific maximal test for the trained modality should be conducted and the HRDP can be used as a simple and practical method of determining the AT, based on which the training intensity can be determined.

Para assegurar esses benefícios, é indispensável uma prescrição adequada às necessidades de cada indivíduo e, para isso, faz-se importante estudar as diferentes respostas cardiorrespiratórias das atividades desenvolvidas nesse meio. Deste modo, o objetivo do estudo foi comparar as respostas cardiorrespiratórias no limiar anaeróbio (LAn) entre o teste máximo de corrida em piscina funda (CPF) e da corrida em esteira terrestre (CET

Aquatic and land aerobic training for patients with chronic low back pain: a randomized study

“…to determine the HR Vt2 used in the prescription for the aquatic environment training, a maximal deepwater running test was performed in accordance with the methodology described in detail by Kanitz et al [27]. to establish the HR Vt2 in the prescription on land, the same progressive test already described for the analyses of VO 2peak and VO 2Vt2 was used.…”

Heart rate deflection point as an alternative to determining the anaerobic threshold in dyslipidaemic patients

“…Accordingly, the HRDP method could be considered simple to implement, requiring less time (around 15 minutes per patient), easy to be incorporated into a training session, and not requiring an invasive procedure. In addition, the HRDP has been found in both trained 18,21,22 and untrained individuals 16,19,20,28 regardless of the age 17,28 and clinical status 23 . Thus, the estimation of the HRDP may be a non-invasive and easy method to determine the AT, which could be used to set and to prescribe individualized training intensities to diverse populations, including dyslipidaemic patients.…”

“…The agreement between the ventilatory method (VT) and HRDP has already been observed in several modalities in healthy individuals [16][17][18][19][20][21][22] and in type 2 diabetes patients 23 . However, no study was found aiming to verify whether HRDP can be used to identify AT in dyslipidaemic patients.…”
