Correction to “Acute kaempferol ingestion lowers oxygen uptake during submaximal exercise and improves high‐intensity exercise capacity in well‐trained male athletes”

Okita, K., Mizokami, T., Yasuda, O., & Ikeda, Y. (2025, May). Acute kaempferol ingestion lowers oxygen uptake during submaximal exercise and improves high‐intensity exercise capacity in well‐trained male athletes. Physiological Reports. 13(9), e70369.

In the final steps, we made errors in converting some figures and tables into journal format. There were errors in the respiratory rate graphs presented in Figure 4 and in the VAS data shown in Table 2.

FIGURE 4.

25% VO_2max condition: The p‐value was incorrectly reported as p < 0.001 and has been corrected to p = 0.001. 50% VO_2max and 75% VO_2max conditions: The graphs of respiratory rate mistakenly displayed VO₂ data from Figure 3 instead of the correct respiratory rate data. The correct graphs are shown here.

TABLE 2.

Regarding the VAS data at 75% VO_2max, muscle fatigue and shortness of breath were incorrectly reported. The correct values are shown here. These changes do not affect the p‐values reported in the text.
