“…Incremental maximal tests involving specific water-based exercises have been investigated in the literature, with the determination of HR and VO 2 values at maximum and associated to the first and second ventilatory thresholds in young [4,16,17,30,31] and postmenopausal women [5]. In addition, the significant relationship between these parameters have been verified throughout the test [29].…”

“…Immersion in the aquatic environment exposes the body to conditions that are different from those on land, mostly due to water's hydrostatic pressure and thermal conductivity [1]. These differences lead to changes in cardiovascular, neuroendocrine and metabolic responses [2,3], impacting maximal and submaximal heart rate (HR) and oxygen consumption (VO 2 ) responses [4,5]. Therefore, the assessment and prescription of exercises in the aquatic environment must consider these changes to ensure an adequate control of training intensity in this environment.…”

Introduction: The anaerobic threshold (AT) determination is important for individualizing the aerobic training prescription. Objective: To compare and verify the agreement between oxygen uptake (VO2), heart rate (HR), and rate of perceived exertion (RPE) at the AT determined by the ventilatory threshold (VT) and heart rate deflection point (HRDP) methods during an aquatic incremental test in trained older women. Methods: Nine elderly women (64.3 ± 4.4 years) engaged in a water-based training program in the last three months performed a maximum incremental test using the water-based stationary running exercise. The test started at a 70 bpm cadence for 2 min, followed by 15 bpm increments every 2 min until exhaustion. VO2, HR and RPE were measured throughout the test and the AT was identified for each method (i.e., VT and HRDP) by three experienced physiologists. Paired t-test and Bland-Altman analysis were used for data analysis (α=0.05). Results: There was no difference between the VT and HRDP methods (p>0.05) and the Bland-Altman analysis showed acceptable agreement between them for all investigated outcomes (VO2: 22.9 ± 5.1 vs. 23.5 ± 4.7 ml.kg-1.min-1, IC95%: -3-+4 ml.kg-1.min-1; HR: 147 ± 11 vs. 147 ± 11 bpm, IC95%: -9-+8 bpm; RPE: 16 ± 1 vs. 16 ± 1, IC95%: -2-+3). Conclusion: Based on these findings, both HR and RPE determined by the HRDP can be used as valid parameters and practical tools for field prescription of intensity during water-based exercises in elderly trained women.Keywords: exercise, aging, exercise test, hydrotherapy, oxygen consumption.

Background: There are a lack of clinical trials with suitable methodological quality that compare aquatic exercise training types in type 2 diabetes (T2D) treatment. This study aimed to compare the effects of aerobic and combined aquatic training on cardiorespiratory outcomes in patients with T2D. Methods: Untrained patients with T2D were randomized to receive an aerobic aquatic training, a combined aquatic training, or a procedure control in 3 weekly sessions for 15 weeks. The sessions were 50 minutes long. The intensities were from 85% to 100% of heart rate of anaerobic threshold and at maximal velocity for aerobic and resistance parts, respectively. Resting heart rate, peak oxygen uptake (VO2peak), and oxygen uptake corresponding to second ventilatory threshold and its relation with VO2peak were evaluated. Results: Participants were 59.0 (8.2) years old and 51% women. Intervention groups increased in VO2peak (aerobic aquatic training group: 4.48 mL·kg−1·min−1, P = .004; combined aquatic training group: 5.27 mL·kg−1·min−1; P = .006) and oxygen uptake corresponding to second ventilatory threshold, whereas the control group presented an increase in oxygen uptake corresponding to second ventilatory threshold and minimal change in VO2peak. Conclusions: Aerobic and combined aquatic exercise interventions improve the cardiorespiratory fitness of patients with T2D.
