Low glycemic CHO ingestion minimizes cognitive function decline during a simulated soccer match

Often cognitive function is affected adversely during prolonged, high intensity exercise. We assessed whether hydrothermally modified corn starch (HMS) ingestion minimizes decline with soccer play. 11 men (177.7 ± 6.8 cm, 77.3 7.9 kg, 22 3 y, 12.8 4.9% body fat, [Formula: see text]O 2 max = 57.1 3.9 ml•kg BM −1 •min ; mean SD) completed 60 min simulated matches HMS (8% CHO; 0.7 g•kg •h 2.8 kcal·kg ) vs isoenergetic dextrose (DEX) consumed 30 prior to the match and at half time. Compared DEX, blood glucose was lower (p < 0.001) 15 (5.3 0.6 7.7 1.4 mmol•L post (5.6 8.3 1.0 ), greater 0.004) after of play (5.8 0.5 5.1 ). With HMS, perceived exertion ratings were reduced throughout 0.025 min). Flanker test incongruent trial reaction time 0.040) conflict cost 0.019) both better HMS. These data suggest that More study warranted elucidate fully cognition benefits for sport performance.
