Article Synopsis
  • - The study explored how ketone monoester affects metabolic and cognitive performance in healthy weight (HW) young adults compared to those with overweight/obesity (OW), using a randomized trial design with a placebo.
  • - Both groups showed changes in blood beta-hydroxybutyrate (BHB) and glucose levels, along with improvements in cognitive function measured through tasks; however, the HW group had more lasting effects on brain connectivity after supplementation.
  • - Overall, higher BHB levels from ketone monoester improved cognitive function by reducing glucose levels and increasing brain activity, indicating potential beneficial effects irrespective of weight status.

Interval training protocols have gained popularity over the years, but their impact on appetite sensation compared to officially recommended training method, moderate intensity continuous training (MICT) is not well understood. Thus, this systematic review and meta-analysis aimed to compare a single session of high intensity interval training (HIIT) including sprint interval training (SIT) with MICT on appetite perception measured by the visual analog scale (VAS). After searching up articles published up to September 2021, 13 randomized controlled studies were included in the meta-analysis.

Background: The efficacy of exercise interventions in the treatment of mental health disorders is well known, but research is lacking on the most efficient exercise type for specific mental health disorders.

Objective: The present study aimed to compare and rank the effectiveness of various exercise types in the treatment of mental health disorders.

Methods: The PubMed, Web of Science, PsycINFO, SPORTDiscus, CINAHL databases, and the Cochrane Central Register of Controlled Trials as well as Google Scholar were searched up to December 2021.

Objective: The aim of our study was to examine cognition response to sprint interval exercise (SIE) against different levels of hypoxia. Research design and methods: 26 recreational active males performed SIE (20 × 6 s of all-out cycling bouts, 15 s of passive recovery) under normoxia (FIO2: 0.209), moderate hypoxia (FIO2: 0.

Objective: The purpose of this study was to investigate the effects of repeated sprint interval training (RSIT) under different hypoxic conditions in comparison with normoxic RSIT on cardiorespiratory fitness (CRF) and metabolic health in sedentary young women.

Methods: Sixty-two sedentary young women (age: 21.9 ± 2.

To examine the effect of acute moderate-intensity continuous exercise performed under normobaric severe hypoxia on cognition, compared to sea-level normoxia. Thirty healthy inactive women randomly performed two experimental trials separated by at least three days but at approximately the same time of day. Executive functions were measured during the follicular stage via an interference control task before (rest) and during exercise with 45% peak power output under normobaric normoxia (PIO₂ = 150 mmHg, FIO₂ = 0.
