Interesting reading about scientific scepticism and critical thinking. The authors refer to Sir Arthur Conan Doyle who wrote “It is a capital mistake to theorize before one has data”. journals.humankinetics.com/view/journals/…

Is the erythrocyte a simple cell that just passively carries oxygen? NO. In our review “Erythrocyte Metabolism” in @ActaPhysiologica, we collaborated with Angelo D'Alessandro and investigated the dynamics of erythrocyte biochemistry and oxygen physiology. bit.ly/rbcmetab

Biochemistry and physiology are inseparable in the erythrocyte. Oxygen transport and release are just a “reaction away” from glycolysis.

Our synthesis shows that the erythrocyte metabolism is more than just an “internal” biochemical matter, but a matter of controlling one of the most important biological processes: loading, transport and delivery of oxygen.

*Nutritional Biomechanics* In exploring caffeine's impact on sprinting, this paper sheds light on the overlooked biomechanical aspects. Biology is not limited by scientists' tool preferences, so Sports Nutrition need not focus solely on metabolism. onlinelibrary.wiley.com/doi/full/10.11…

While the “beetroot” field may be oversaturated, this seems a carefully executed study, a rarity in this field. It shows that prolonged beetroot juice intake does not improve vascular function or lower blood pressure in older adults with hypertension. pubs.rsc.org/en/content/art…

A thoughtful short comment by Michalis Nikolaidis, encourages researchers to trust again their inner drive and avoid becoming part of an academic “rat race”.

If free radicals did not exist, it would be necessary to invent them. A play on a famous quote by Voltaire, highlighting the tendency to oversimplify/misattribute complex biological phenomena to free radicals, rather than acknowledging the gaps in understanding these processes.

Την ερχόμενη Τρίτη 2 Ιουλίου 2024 στις 12:00 στο ΤΕΦΑΑ Σερρών ο Παναγιώτης Χατζηνικολάου υποστηρίζει τη διδακτορική του διατριβή με θέμα: «Οι οξειδοαναγωγικές επιδράσεις της άσκησης στην κόπωση: μια ποσοτική προσέγγιση»

This study highlights that eccentric contractions in mice increase hydrogen peroxide levels more than concentric, likely due to NADPH oxidase 2 activation. Differences in adaptations between eccentric & concentric exercise may involve a redox component. journals.physiology.org/doi/abs/10.115…

Ελεύθερες ρίζες. Το όνομά τους τρομάζει: είναι «ελεύθερες» (άρα ανεξέλεγκτες) και «ριζώνουν». Με τέτοιο όνομα, πώς να μην θεωρούνται το «κακό παιδί» της βιολογίας; Στο παρακάτω podcast, με Nikos Margaritelis, επιχειρούμε να δώσουμε μια πιο ρεαλιστική εικόνα. youtube.com/watch?v=z9wLph…

Our recent publication at Eur J Nutr showed that a higher protein intake (1.2–1.5 g/kg/day) alone may aid in preserving muscle mass and sustaining physical performance in individuals with type 2 diabetes. link.springer.com/article/10.100…

Pleasure to collaborate with Panos Chatzinikolaou and Cameron A. Schmidt, PhD on this work dealing with the i-space a proteoform centric theory of redox regulation sciencedirect.com/science/articl…

Eur J Appl Physiol now welcomes reviews from all thinkers—whether or not they identify as physiologists. A great review is not about labels but about curiosity, depth & synthesis. Young scientists, your fresh takes are especially invited. My editorial: link.springer.com/article/10.100…

If you have a review ready, submit it. If you have an idea, fill out our proposal template and send it to us for consideration. There are no any restrictions. While science often rewards those who produce results, true progress depends equally on those who make sense of them.

Vitamin C+E supplementation blunts molecular adaptations to sprint interval training but not performance gains. Since performance wasn’t impaired, I wonder whether, and to what extent, the blunted molecular responses can truly be considered detrimental. physoc.onlinelibrary.wiley.com/doi/10.1113/JP…

The new study by Panos Chatzinikolaou, led by Michalis Nikolaidis and published in Sports Medicine, focused on complexity of erythrocyte metabolic pathways that regulate oxygen loading, transport, and delivery.

This one finds that erythrocytes, like any other cell in the human body, can respond to exercise and that erythrocyte metabolism becomes dysregulated under oxidative stress and may partly influence muscle oxygenation and performance.
