“…However, correlation tests do not express agreement between methods, and this is a common statistical procedure error seen in the relevant literature (3,14). Therefore, the absolute agreement between T RPE and AT was tested using Lin's agreement coefficient, and significant concordance was observed (Pc = 0.84 [0.66–0.92 CI 95%]) and confirmed using the Bland-Altman technique (−4.7 [−34.2/24.7 CI 95%] watts) (Figure 3A), which produced a value similar to that reported by Madrid et al (15) for the RPE-13 protocol (−4.7 [−27.0/17.6 CI 95%] watts). Furthermore, the reliability of T RPE in AT estimation was also confirmed using the ICC (0.84 [0.64–0.94 CI 95%]), and the accuracy of the method was observable from the small CV differences of T RPE (CV = 20.74) and AT (CV = 16.44).…”

“…Madrid et al (15) tested the validity of an RPE score of 13 AU in MLSS estimation using the RPE-13 protocol. The study included physically active men, and the protocol for MLSS estimation consisted of 3-stage 3-minute exercises with RPE scores of 10, 13, and 16 AU at each stage.…”

“…Despite the proven association between RPE scores and AT, only a few studies have tested the validity (agreement) of RPE for AT estimation (10,15). The different RPE strategies used for AT estimation need complementary mathematical procedures such as linear regression and the maximum distance (10,18,33), which may limit the applicability of the evaluation methods.…”

The objective of the study was to investigate the validity of the rating of perceived exertion threshold (T RPE ) for anaerobic threshold (AT) estimation during an incremental test (IT) on a cycle ergometer. Nineteen physically active and healthy men performed an IT on a cycle ergometer. The intensity corresponding to the AT was considered as the point immediately before the abrupt increase in blood lactate concentration ([La]) in the IT. T RPE was determined in the last intensity corresponding to perceptual response previous the 15 arbitrary units (AU) in the 15-point RPE scale. The heart rate (HR), [La], and RPE were obtained at the end of each stage of the IT. There was no significant difference between workload obtained from the watts) and T RPE (150 [120-150] watts) (p . 0.05). In addition, there were no differences between HR (AT, 139.5 6 12.7 b•min 21 vs. T RPE , 141.9 6 14.6 b•min 21 , p . 0.05) and [La] (AT, 3.1 [2.8-3.2] mM vs. T RPE , 3.1 [2.9-3.7] mM, p . 0.05). There was a strong correlation between the intensities in AT and T RPE during the IT (r 5 0.88). A substantial reliability (intraclass correlation coefficient 5 0.84 [0.64-0.94 confidence interval 95%]) was evidenced, as well as a substantial agreement between the AT and T RPE intensities (Pc 5 0.84), as confirmed by the Bland-Altman plot (24.7 [2 34.2/24.7]). T RPE was a predictor of the AT (b 5 1.146, R 5 0.770, SEE 5 15.070, p , 0.01). It can be concluded that T RPE is valid for AT estimation during an IT on a cycle ergometer.

“…Several studies have accepted the RPE as a valid submaximal test to estimate, monitor and guide the exercise intensity in various population including healthy older adults (Chung, Zhao, Liu & Quach, 2015), young athletes (Manoel et al, 2016), healthy sedentary individuals , physically active individuals (Al-Rahamneh & Eston, 2011;Madrid et al, 2016), and cardiac rehabilitation patients (Klinger, McConnell & Gardner, 2001). These studies confirmed the validity of RPE scale based on its linear relation with HR and VO 2 during exercise testing and aerobic exercises.…”

ii iii ABSTRACT Alajmi, R. A. Comparison of non-maximal tests for exercise prescription and outcome assessment. MS in Clinical Exercise Physiology, December 2017, 71pp. (C. Foster) This study examined the accuracy of non-maximal tests: the Talk Test (TT), Rating of Perceived Exertion (RPE) extrapolation, Rockport Walking Test (RWT) and non-exercise VO 2 max prediction equation for predicting exercise capacity (VO 2 max and VT). Subjects (N=20) were 18-50 yrs. of low to moderate fitness level. Subjects performed three exercise sessions. Test 1 was a maximal incremental test to measure VO 2 max and VT. Test 2 was a submaximal incremental exercise test without respiratory gas exchange measurements, using the TT and RPE. Test 3 was the RWT. Also, VO 2 max was calculated using the non-exercise prediction equation of Matthews et al. (1997). The results showed that there was no significant difference between measured VO 2 max and predicted VO 2 max using the non-exercise equation, extrapolation to RPE19 and the RWT. However, measured VO 2 max was significantly less than predicted VO 2 max using extrapolation to RPE 20 (p≤0.05). There was no significant difference (p>0.05) between the VO 2 at VT, the LP, and EQ stages of the TT, and at RPE13 and RPE14. However, the VO 2 at RPE 15 was significantly higher than VO 2 at VT (p≤0.05). In conclusion, the results showed that the non-maximal methods could be used as primary methods for exercise prescription and outcome assessment.iv ACKNOWLEDGEMENTS

It has been shown that engaging in regular physical exercise yields short- and long-term health benefits, primarily by mitigating the risk for cardiovascular disease, but little information is known about physical deconditioning at aging process. The aim of the present study was to analyze the aerobic capacity, through maximal lactate steady state (MLSS), in Wistar rats of different ages (2,4, 6 e 12 months ) and physical conditioning deconditioning responses in middle-aged rats. The results were significant for weight gain in the sedentary (588 ± 71 g) and detraining animals (576 ± 62 g) at 12 months, whereas the conditioned group maintained their original body weights – BW (515 ± 72 g), similar at four (455 ±17 g) and six months of age (471 ± 37 g). MLSS decreased with age (2 months sedentary (8.4 ± 1% Body Weight, 4 months sedentary (6.4 ± 0.6% BW), 6 months sedentary (5.8 ± 1% BW), 12 months sedentary (5.1 ± 0.7% BW), but physical exercise was effective in attenuating the age-related loss of aerobic capacity after 12 months (5.8 ± 1.3% BW). The physical detraining was (5.3 ± 0.4% BW) was similar at 12 months trained. The physical training in long term protected against the increased of the body weight and fat depots caused by aging, but, this effect was found by deconditioning physical. Additionally, the physical training attenuated the aerobic capacity loss due to aging process and this effect was maintained after detraining physical.
