Muscular Oxygen Saturation and Hemoglobin Concentration during Freediving: A Case Study

Autor: Dario Vrdoljak, Željko Dujić, Nikola Foretić

Publikováno v: Oxygen, Vol 4, Iss 3, Pp 285-294 (2024)

Lower limb muscle fatigue is the main reason for withdrawal from diving. Therefore, this study aimed to determine the local muscle oxygen saturation and hemoglobin concentration in the vastus lateralis muscle during different freediving disciplines.

Autor: Ivan Drviš, Dario Vrdoljak, Goran Dujić, Željko Dujić, Nikola Foretić

Publikováno v: Sports, Vol 12, Iss 4, p 110 (2024)

Breath-hold diving is explained as an activity that requires enduring muscle asphyxia and acidosis, high anaerobic capacity, and the tactic of the dive. Therefore, this study aimed to construct and validate tests that will mimic anaerobic processes i

Local Muscle Oxygenation Differences between Lower Limbs according to Muscle Mass in Breath-Hold Divers

Autor: Ognjen Uljević, Dario Vrdoljak, Ivan Drviš, Nikola Foretić, Željko Dujić

Publikováno v: Symmetry, Vol 16, Iss 3, p 377 (2024)

Oxidative potential and anaerobic capacity could be influential to the training regimen and performance of breath-hold diving (BHD) athletes. Therefore, this study aimed to determine the differences in local muscle oxygenation between the lower limbs

Breath-Hold Diving – The Physiology of Diving Deep and Returning

Autor: Alexander Patrician, Željko Dujić, Boris Spajić, Ivan Drviš, Philip N. Ainslie

Publikováno v: Frontiers in Physiology, Vol 12 (2021)

Breath-hold diving involves highly integrative physiology and extreme responses to both exercise and asphyxia during progressive elevations in hydrostatic pressure. With astonishing depth records exceeding 100 m, and up to 214 m on a single breath, t

Lord, Tony Dawkins, Aimee Drane, Michael Stembridge, Tanja Dragun, Otto Barak, Boris Spajić, Ivan Drviš, Joseph W. Duke, Glen E. Foster, Philip N. Ainslie, Željko Dujić, Andrew T. Lovering

Publikováno v: Journal of Science and Medicine in Sport. 25:553-556

Objectives: During apnea diving, a patent foramen ovale may function as a pressure relief valve under conditions of high pulmonary pressure, preserving left-ventricular output. Patent foramen ovale prevalence in apneic divers has not been previously

Case Studies in Physiology: Breath-hold diving beyond 100 meters—cardiopulmonary responses in world-champion divers

Autor: Hannah G. Caldwell, Darija Bakovic-Kramaric, Alexander Patrician, Boris Spajić, Ivan Drvis, Otto F. Barak, Christopher Gasho, Philip N. Ainslie, Željko Dujić

Publikováno v: Journal of Applied Physiology. 130:1345-1350

In this case study, we evaluate the unique physiological profiles of two world-champion breath-hold divers. At close to current world- record depths, the extreme physiological responses to both exercise and asphyxia during progressive elevations in h
