Article Synopsis
- This study explored how photobiomodulation therapy (PBMT) affects the time to exhaustion and energy usage in amateur athletes during treadmill running in both low oxygen (hypoxia) and normal oxygen (normoxia) conditions.
- * It involved 11 male participants who underwent tests to measure their maximal oxygen uptake and then participated in treadmill runs under various conditions with and without PBMT.
- * Results showed that time to exhaustion was shorter in hypoxic conditions, but PBMT increased anaerobic energy contribution in hypoxia without improving overall exhaustion times.
The aim of this study was to investigate the effect of 8 weeks of hypoxic exposition and physical training on healthy mice femur outcomes analyzed through conventional statistic and complex networks. The mice were divided into four groups, subjected to physical training (T; 40 min per day at 80% of critical velocity intensity) or not (N), exposed to hypoxic environment ("Living High-Training Low" model - LHTL; 18 h per day, FIO=19.5%; Hyp) or not (Nor).

- This study aimed to validate an alternative measure of anaerobic contribution, called AOD_alt, against the traditional method, Accumulated Oxygen Deficit (AOD).
- In two experiments, participants performed intense cycling exercises in both normal (normoxia) and low oxygen (hypoxia) conditions while physiological responses were measured.
- Results showed that AOD_alt was correlated with AOD in most conditions, confirming AOD_alt as a valid measure of anaerobic capacity, especially during severe exercise and in hypoxic environments.
The present study aimed to verify the effect of acute nitrate supplementation on oxidative, phosphocreatine, and glycolytic energy contribution (C, C, and C respectively) during a high-intensity intermittent exercise (HIIE). Fifteen physically active subjects were submitted to incremental running test on a treadmill and two random HIIE (10 × 1 min at maximal aerobic speed with 1 min of passive recovery) in the following conditions: sodium nitrate (SN) or Placebo (PL). Repeated measure ANOVA was used to compare C, and C within the 10 efforts.

Following a graded exercise test to determine maximal oxygen uptake intensity (iVO), 26 recreational runners performed a time to exhaustion effort (TTE) as baseline at 110% iVO. The same TTE was performed in fasting state, then, a muscle glycogen depletion protocol was executed.
