Although it has been hypothesized that moderate to vigorous exercise immediately modulates cognition via ascending arousal system activation, such activation during very-light to light exercise has remained uncertain. Here, we aimed to uncover the exact exercise intensity necessary for ascending arousal system activation using pupillometry. The pup...

This study aimed to compare cerebral oxyhemoglobin (O2Hb) levels during incremental exercise by cycling vs. arm cranking in 12 healthy adult men aged 20.8 ± 0.2 years old. O2Hb was measured by near-infrared spectroscopy. Regions of interest included the left and right prefrontal cortices (LtPFC and RtPFC, respectively), the left and right premotor ...

The aim of the present study was to investigate potential anti-inflammatory effects of wet-cupping prior to a moderate-to-vigorous exercise test among martial arts athletes. Twenty-one male karate athletes voluntarily participated in this study and were randomly divided into 3 groups: vigorous exercise (VE, n = 7), cupping (CT, n = 7) and cupping p...

The objective of this study was to investigate the effects of chronic Rhodiola rosea (R. rosea) supplementation on mental and physical performance, as well as hormonal and oxidative stress biomarkers. Twenty-six healthy male students received either R. rosea extract (600 mg/day; RR) or placebo (PL) in a randomized double-blind trial. Prior to suppl...

Commonly performed during an incremental test to exhaustion, maximal oxygen uptake (V̇O2max) assessment has become a recurring practice in clinical and experimental settings. To validate the test, several criteria were proposed. In this context, the plateau in oxygen uptake (V̇O2) is inconsistent in its frequency, reducing its usefulness as a robus...

PurposeThe goal of this study was to quantify obesity-related differences in systemic physiologic responses and cerebral hemodynamics during physical work to exhaustion.MethodsTwenty men, ten who are obese and ten of healthy weight, completed an incremental exercise lifting a box from 25 cm below to 25 cm above knuckle height at 10 lifts/min. The l...

Recent studies postulated that increased oxygenation of the prefrontal cortex (PFC) during elevating exercise intensities reflects a specific activation of this region. Furthermore, the drop in PFC oxygenation often measured shortly before exhaustion is interpreted as a main factor limiting exercise. Nevertheless, a limitation of these studies is t...

Purpose The aim of this project was to study the impact of pedal rate on breakpoints in muscle oxygenation (deoxy[Hb + Mb] and total[Hb + Mb]) and activation (iEMG and MPF) at high intensities during ramp exercise.MethodsTwelve physically active students performed incremental ramp exercises at 60 rpm, starting either at 50 or 80 W (i.e., 60rpm50 an...
