Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
HNO: High intensity interval training (HIIT) + nitrate supllementation (NO3-).
Performed 12 high-intensity interval-training (HIIT) sessions during a 4-week period (3 sessions/ week) under normobaric hypoxia conditions (FiO2=\~13%, \~3000 m) with NO3- supplement.
Nitrate + Hypoxia
The combined effect of nitrate supplementation and hypoxia training on both performance and health at sea-level and altitude conditions.
HPL: High intensity interval training (HIIT) + placebo supllementation.
Performed 12 high-intensity interval-training (HIIT) sessions during a 4-week period (3 sessions/ week) under normobaric hypoxia conditions (FiO2=\~13%, \~3000 m) with placebo supplement.
Placebo + Hypoxia
The combined effect of placebo supplementation and hypoxia training on both performance and health at sea-level and altitude conditions.
CON: High intensity interval training (HIIT) + placebo supllementation.
Performed 12 high-intensity interval-training (HIIT) sessions during a 4-week period (3 sessions/ week) under normoxic conditions (FiO2=\~20.9%) with placebo supplement.
Control
The combined effect of placebo supplementation and normoxia training on both performance and health at sea-level and altitude conditions.
