Special Issue Information

Dear Colleagues,

It is well known that most people in industrialized societies are engaged in far less physical activity than the human body requires. Regular exercise puts physical and metabolic stress on the body, increases the amount of energy that it burns while exercising, boosts the resting energy expenditure and affects more physiological systems than any other everyday activity.

In particular, the biochemistry of exercise is not only a primary concern of athletes and exercise physiologists, but also has important implications for those who engage in moderate exercise only, as well as sedentary individuals. Exercise also has profound beneficial effects on the biochemistry of people with diabetes, obesity and other metabolic disorders, while the recent COVID-19 outbreak has revealed that exercise and physical activity provide protection against severe COVID-19 disease and comorbidities such as obesity and cardiovascular diseases, that belong to the most important factors affecting mortality after SARS-CoV2 infection.

Herein, we set up a Special Issue to incorporate papers focusing on exercise physiology and biochemistry, i.e., the study of acute responses and chronic adaptations to exercise. It will include, but is not limited to, the following topics: physical or motor activity and biomechanics, exercise training, exercise metabolism, thermoregulation, systemic physiological responses (musculoskeletal, cardiovascular, respiratory, endocrine, etc.), and clinical exercise physiology and biochemistry.

This Special Issue aims to present advances and new insights into the molecular, cellular and systemic mechanisms that mediate acute and adaptive responses to exercise in health and disease.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Physiologia is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Citrulline malate (CM) has been touted as a nutritional ergogenic aid for sports performance, with purported mechanisms of increased muscle blood flow, ammonia clearance, and adenosine triphosphate resynthesis. Combined, these physiological benefits may be best applied to whole-body endurance exercises, such as swimming, though this postulate has not yet been explored. In a double-blind, randomised, and crossover design, 11 national-level swimmers (age: 17 ± 3 years, height: 1.71 ± 0.05 m, body mass: 60.6 ± 8.3 kg) from a high-performance swimming club ingested either 15 g CM or a placebo (PLA) 60 min before six × 300 m freestyle bouts (at 4.5 min intervals). Blood lactate, blood pressure, and ratings of perceived exertion were measured at baseline, 60 min post-ingestion, and immediately post-exercise. Neither mean 300 m swimming time (CM: 212.0 ± 9.6 vs. PLA: 212.8 ± 7.7 s, p = 0.683, g = 0.09) nor any individual swimming bouts (p = 0.679, Pŋ2 = 0.02) were improved with CM ingestion. Moreover, no differences in any physiological or subjective measures were identified between conditions (all p > 0.05). Whether the proposed CM mechanisms were active was unclear as more direct physiological measures (i.e., plasma NO, ammonia) may have been required. Resultantly, these observations do not support an ergogenic effect of acute CM ingestion in highly trained swimmers. Full article
