“…The VO 2max of the MD group in this study was 61.0 ± 6.3 mL/kg/min, and this is the first study using the AC [La] + EP-OCfast method in athletes with a high aerobic capacity in which their VO 2max exceeded 60.0mL/kg/min. Therefore, the A 1 of the MD group in this study was 43.9 ± 5.0 mL/min/kg, which was higher than previous studies that reported A 1 values between 14.9 to 27.8 mL/min/kg [4,8,18]. In addition, a significant correlation was found between VO 2peak and A 1 (▶ Fig.…”

“…Heart rate (HR) was monitored using a heart rate monitor (Polar 430 H10; Polar, Finland). Additionally, subjective perceived exertion (RPE) was recorded on a Borg scale (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) at the end of each stage or after exhaustion in all tests.…”

The anaerobic capacity (AC[La]+EPOCfast ) method is of interest as it can differentiate between the contributions of phosphocreatine(PCr) and glycolytic energy, assess the anaerobic metabolism during a single effort, and evaluate various exercise modalities. However, no previous studies have investigated whether the superiority of the PCr and glycolytic systems can be assessed in athletes with high anaerobic capacity. This study aimed to compare the AC[La]+EPOCfast method in seven sprinters (SP) and seven middle-distance runners (MD). The participants underwent a graded exercise test and constant-load exercise at 115% VO2max until exhaustion using a bicycle ergometer. AC[La]+EPOCfast was calculated as the sum of oxygen equivalents from the phosphagen (EPCr) and glycolytic (ELa) pathways. This study reveals that there was no significant difference in AC[La]+EPOCfast or maximal accumulated oxygen deficit (MAOD) between the two groups. Although EPCr was not significantly different between groups, ELa was significantly higher in the SP group than in the MD group. In conclusion, the AC[La]+EPOCfast method can be used to evaluate high and low anaerobic capacities. However, further studies on athletes with high aerobic capacity are required.

Acute high-intensity intermittent exercise (HIIE) induces the myokine secretion associated with neurogenesis, as well brain-derived neurotrophic factor (BDNF); however, it remains unknown how the menstrual phase influences this secretion after an acute exercise session. The current study aimed to investigate the effects of HIIE performed in luteal and follicular menstrual phases on BDNF, cognitive function, mood, and exercise enjoyment. Fourteen healthy women completed four experimental sessions, randomly. One graded exercise test (GXT) and one HIIE session (10 × 1-min runs 90% peak GXT velocity [1-min recovery]) were performed for each menstrual phase. Blood samples were collected at rest and immediately after efforts, and the profile of mood states questionnaire (POMS) and Stroop-task test were applied. During the HIIE, subjective scales were applied (feeling, felt arousal, rate of perceived exertion, and physical activity enjoyment). The main results showed that the serum BDNF presented no difference between menstrual phases (p = 0.870); however, HIIE increased BDNF concentration in both menstrual phases (p = 0.030). In addition, the magnitude of circulating BDNF variation (Δ%BDNF) and $$\dot{\text{V}}{{\text{O}}}_{\text{2max}}$$ V ˙ O 2max demonstrated an inverse relationship in the follicular phase (r = − 0.539, p = 0.046), whereas in the luteal phase, Δ%BDNF was negatively correlated with time test (r = − 0.684, p = 0.007) and RPE (r = − 0.726, p = 0.004) in GXT. No differences between menstrual phases were observed for POMS (p ≥ 0.05); however, HIIE attenuated tension (p < 0.01), depression (p < 0.01), and anger moods (p < 0.01), independently of menstrual phases. The subjective scales and Stroop-task test did not show differences. In conclusion, menstrual cycle phase does not affect serum BDNF levels, cognitive function, mood, and exercise enjoyment. Contrary, HIIE increases peripheral BDNF and attenuates tension, depression, and anger independently of menstrual phase. In addition, Δ%BDNF was correlated with physical fitness in the follicular phase, exhibiting higher changes in women with lower physical fitness status.

The study aimed to investigate the effect of high-intensity intermittent effort (HIIE) performed in luteal and follicular menstrual phases on BDNF, cognitive function, mood and exercise enjoyment. Fourteen healthy women completed four experimental sessions, randomly. For each menstrual phase one graded exercise test (GXT) and one HIIE session (10 × 1-min runs 90% peak GXT velocity [1-min recovery]) were performed. Blood samples were collected at rest and immediately after efforts, as well profile of mood states questionnaire (POMS) and Stroop-task application. During the HIIE, subjective scales were applied (feeling, felt arousal, rate of perceived exertion and physical activity enjoyment). In serum BDNF no difference was observed between menstrual phases (p = 0.87). Nevertheless, HIIE increased BDNF concentration during two phases (p = 0.03). In addition, the magnitude of circulating BDNF changes (BDNFΔ) and VO2max showed an inverse relationship in follicular phase (r= -0.539, p = 0.046), whereas in luteal phase the BDNFΔ were negatively correlated with duration (r= -0.684, p = 0.007) and RPE (r= -0.726, p = 0.004) in GXT. No difference between menstrual phases was observed for POMS (p ≥ 0.05); however, HIIE attenuates tension (p < 0.01), depression (p < 0.01) and anger moods (p < 0.01), independently of menstrual phases. Subjective scales and Stroop-task did not show differences. Menstrual cycle does not affect BDNF, cognitive function, mood and exercise enjoyment, but HIIE increases peripheral BDNF and attenuate tension, depression and anger independently of menstrual phase. Besides, the BDNFΔ were correlated with fitness status in follicular phase, exhibiting higher changes in women with lower fitness status.
