Theoretical and Experimental Analysis of Pumps as Turbines

open access: yes, 2019
La seguente tesi di dottorato è incentrata sull’analisi teorica e sperimentale delle pompe utilizzate come turbine (comunemente chiamate in inglese Pumps as Turbines – PaTs). Il tema di ricerca è stato condotto in collaborazione con Nuovo Pignone Bari, che ha finanziato il progetto di ricerca stesso.

Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.

Commuting by bicycle (vs. by car) is associated with improved aerobic power, microvascular function and diminished CO2 output in the atmosphere

open access: yesExperimental Physiology, EarlyView.
Abstract The study investigated whether bicycle compared with car commuting, over relatively small distances, has positive effects on physiological variables, cardiometabolic fitness and CO2 output in the atmosphere. Bike Commuters (11 M, 15 F; age [median value (interquartile range)] 51.5 (38.3–56.8) years; body mass index [BMI] 22.8 (21.0–24.1) kg m ...

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

open access: yesExperimental Physiology, EarlyView.
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

How do physiological networks respond to normobaric hypoxia and isometric exercise?

open access: yesExperimental Physiology, EarlyView.
Abstract The dynamics of physiological systems are impacted by both exercise and hypoxia. Network models can be used to map the interactions between various physiological components in environmental physiology and exercise using the concepts of information theory.
