“…32 For example, a study involving cycle ergometer performance showed a strong correlation between HRDP and AT determined by ventilatory threshold ( r = 0.90, p < 0.001), with no significant differences. 34 As well, when HRDP was compared with AT verified by blood lactate during a running test, it also showed a strong correlation ( r = 0.84, p < 0.0001) without significant differences between both methods ( p > 0.05). 26 This relation has been reinforced by the absence of differences during repeated tests, which suggests that it is a reliable method to find the HRDP, 32 which can be easily identified in individuals with higher training levels.…”

This study aimed to investigate the validity of a boxing-specific test to predict anaerobic threshold (AT) using the heart rate deflection point (HRDP) in boxing athletes with mobile technology. Ten male boxing athletes performed the boxing-specific incremental test (TBOX). Maximal heart rate (HRMAX), HRDP, pace, maximal punch frequency (FPMAX), and punch frequency relative to HRDP (FPAT) were measured. Participants also performed an incremental running test on a treadmill (IT) as a reference test. Paired t-tests were performed to verify differences between the mean values of HRMAX and HRDP during TBOX and IT. Pearson linear correlation was applied to test correlations and the Bland and Altman visual analysis was used to verify the level of agreement. A significant level of p < 0.05 was adopted. The average HRDP was 174 ± 7 bpm, which corresponded to 92% of the observed HRMAX. FPAT and FPMAX presented values between 39 ± 4 and 73 ± 8 blows, respectively. No differences were found, and strong correlations were evidenced between TBOX and IT for HRMAX ( p = 0.281; r = 0.73) and heart rate response related to HRDP ( p = 0.096; r = 0.85). The 95% limits of agreement for the differences between TBOX and IT for HRMAX should be considered with bias by 2.1 ± 9.7 found between −7.65 and 11.85, as well as the 95% limits of agreement for the differences between TBOX and IT for HRDP with bias −2.3 ± 7.68 found between −9.98 and 5.38. HRMAX and HRDP obtained during TBOX leads us to infer that the test was well founded to estimate parameters associated with the aerobic power and aerobic capacity of boxing athletes. In addition, TBOX shows significant applicability for the aerobic assessment of boxers based on real competition movements and can be useful to determine and control training intensities.
