Abstract

Highly branched cyclic dextrin (HBCD) is a novel type of maltodextrin with a narrow molecular weight distribution that is produced from starch. In this study, we investigated the effects of HBCD administration on endurance performance. Seven elite swimmers participated in three trials, conducted in random order. In each trial, the subjects received either HBCD, glucose (1.5 g carbohydrate/kg body weight) or water (as a control), and immediately carried out 10 cycles of intermittent swimming consisting of 5 min of swimming at 75% followed by 3 min of rest, and subsequent swimming at 90% to exhaustion. The time to fatigue was about 70% longer in the HBCD trial than that in the glucose and control trials, a significant difference. Plasma glucose in the HBCD group was maintained at higher levels during pre-swimming cycles than that in the glucose or water group. These results suggest that HBCD administration enhances endurance performance.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several studies have shown that HBCD improves gastrointestinal outcomes, reduces gastric emptying time, has positive effects on endurance sports performance, decreases rating of perceived exertion during prolonged exercise, and attenuates stress hormonal response and reduces urinary cytokine levels after extensive exercise in triathletes.

    “Several studies have shown not only improvements at the gastrointestinal level [82] and a reduction on the gastric emptying time [78] but also positive effects on endurance sports performance [83], a decrease in the rating of perceived exertion during prolonged exercise [84] and even an attenuation in the stress hormonal response and reduction of urinary cytokine levels after extensive exercise in”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
