Journal ArticleDOI
Concentric and eccentric: muscle contraction or exercise? New perspective.
Johnny Padulo,Karim Chamari,Alberto Concu,Juliano Dal Pupo,Guillaume Laffaye,Alessandro Moura Zagatto,Luca Paolo Ardigò +6 more
TL;DR: This research presents a novel approach called “Sports Performance Optimization with real-time reinforcement learning”, which automates the very labor-intensive and therefore time-heavy and expensive process of training athletes to improve their physical and mental performance.
Journal ArticleDOI
The effects of daytime melatonin ingestion on arousal and vigilance vanish after sub-maximal exercise: a pilot study.
Amine Souissi,Mohamed Amine Farjallah,O. Gaied Chortane,Ismail Dergaa,Mohamed Arbi Mejri,Nawel Gaamouri,N. Souissi,Karim Chamari,K. Weiss,Houda Ben Saad,Amine Ghram,Beat Knechtle +11 more
TL;DR: The effect of submaximal exercise on vigilance and arousal following acute melatonin ingestion has not yet been studied as discussed by the authors , but it is known that physical exercise is known to produce an increase in core temperature and circulating cortisol which can enhance arousal and vigilance.
Journal ArticleDOI
Correlation of gas exchange threshold and first muscle oxyhemoglobin inflection point with time-to-exhaustion during heavy-intensity exercise.
TL;DR: The anaerobic threshold as identified from GET was concomitant to [O2Hb]-T, and could therefore be used as a performance index in middle-duration events.
Journal ArticleDOI
Effect of Aerobic Physical Exercise and Training Status on the Perceived Egocentric Distances
TL;DR: In this article, the effect of moderateintensity-exercise and training status on the perception of the egocentric distance (PED) was investigated and the results showed that the precision of PED was greater in trained than untrained subjects (p<0.05) and during and after the exercise in comparison with before the physical task.
Journal ArticleDOI
Athlete level, sport-type, and gender influences on training, mental health, and sleep during the early COVID-19 lockdown in Malaysia
Jad Adrian Washif,Lian Yee Kok,C. James,C. Martyn Beaven,Abdulaziz Farooq,David B. Pyne,Karim Chamari +6 more
TL;DR: In this paper , the authors evaluated the extent of changes in training practices, recovery, mental health, and sleep patterns of athletes during the early COVID-19 lockdown in a single country-cohort.
