Abstract

Hyperthermia accelerates dehydration and can lead to a glycolysis malfunction. Therefore, to deeply understand the relationship between dehydration and hyperthermia during exercise, as well as in the recovery time, there might be important factors to improve athletic performance. A systematic review was carried out in different databases using the words “hydration” OR “dehydration” AND “glycogen” OR “glycogenesis” OR “glycogenolysis” AND “muscle” OR “muscle metabolism” OR “cardiovascular system” and adding them to the “topic section” in Web of Science, to “Title/Abstract” in PubMed and to “Abstract” in SPORTDiscus. A total of 18 studies were included in the review and 13 in the meta-analysis. The free statistical software Jamovi was used to run the meta-analysis (version 1.6.15). A total sample of 158 people was included in the qualitative analysis, with a mean age of 23.5 years. Ten studies compared muscle glycogen content after hydration vs. remaining dehydrated (SMD −4.77 to 3.71, positive 80% of estimates, \hat{\mu} = 0.79 (95% CI: −0.54 to 2.12), z = 1.17, p = 0.24, Q-test (Q(9) = 66.38, p < 0.0001, tau2 = 4.14, I2 = 91.88%). Four studies examined the effect of temperature on postexercise muscle glycogen content (SMD −3.14 to −0.63, 100% of estimates being negative, \hat{\mu} = −1.52 (95% CI: −2.52 to −0.53), (z = −3.00, p = 0.003, Q-test (Q(3) = 8.40, p = 0.038, tau2 = 0.68, I2 = 66.81%). In conclusion, both hyperthermia and dehydration may contribute to elevated glycogenolysis during exercise and poor glycogen resynthesis during recovery. Although core and muscle hyperthermia are the key factors in glycogen impairments, they are also directly related to dehydration.

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

  • Re-establishing water and electrolyte balance during the post-exercise recovery period is important.

    “Therefore, re-establishing water and electrolyte balance during the post-exercise recovery period is important [100].”

    From Nutritional Strategies to Improve Post-exercise Recovery and Subsequent Exercise Performance: A Narrative Review (2025) · cites this paper as [100]

    The Discussion supports the importance of post-exercise fluid replacement for recovery, particularly for restoring muscle glycogen and avoiding hypohydration before subsequent exercise. The cited passages do not address restoring electrolyte balance, so that part of the claim is unsupported. (LLM, conf=0.86)

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.
