the sports drink, probably due to the higher energy content of the later, resulting in delayed gastric emptying and slow absorption rate after hyperhydration ( Okabe et al., 2015 ). During the baseline phase, all the samples were reported with LH values above the threshold of 1.0 IU/L, while 24.6% and

were given 5 min to consume 20 g of the supplement dissolved in 300 ml of warm water. To standardize gastric emptying, no further fluid was allowed for 60 min after the supplement ingestion and no food was consumed or exercise performed for 3 hr, after which, the participants returned to their normal

Despite previous concern about delayed gastric emptying associated with the addition of solutes to an exercise beverage, carbohydrate-containing drinks

“ileal brake” mechanism to attenuate gastric emptying and orocaecal transit. This involves neural and hormonal negative feedback signals from the terminal ileum and proximal colon targeting the stomach and duodenum ( Shin et al., 2013 ). Of practical and performance relevance, considering the gastric

to a delay in gastric emptying ( De Oliveira et al., 2014 ; Jeukendrup, 2017 ). General protein intake guidelines for athletes recommend 1.2–2.0 g/kg per day ( Egan, 2016 ; Thomas et al., 2016 ). In the present study, protein intake was at the higher end of these guidelines. A high protein intake

correlated with reductions in performance. Although digested slowly in the small intestine, gastric emptying for modified AMY-7 has been reported to be similar to other maltodextrins ( Severijnen et al., 2007 ). Confirming previous findings ( Johannsen & Sharp, 2007 ), subjects in the present study did not

Furthermore, caution is required when coingesting caffeine with a pretest meal, which may slow gastric emptying and delay caffeine absorption. 10 Another popular substance is sodium bicarbonate, which is an effective exogenous buffer causing preexercise alkalosis and buffering the accumulation of H + during

However, it can be relatively short (∼6 h) provided all recommendations are fulfilled. 35 Another parameter of the cardiovascular system that can be altered after training or competition is the maximal excitability of the autonomic
