Acute ergogenic effects of repetitive maximal breath-holding maneuvers on hematological and physiological responses: a graded exercise test investigation.
Eur J Appl Physiol
October 2024
Sports Medicine Laboratory, School of Physical Education and Sport Science, Aristotle University of Thessaloniki, Campus AUThThermi, 57001, Thessaloniki, Greece.
Article Synopsis
- Repetitive maximal breath-holding (BH) could improve physical performance by enhancing blood properties and oxygen delivery.
- The study involved 17 trained participants completing a graded exercise test (GET) after performing five breath-holds, leading to significant changes in blood indicators like increased red blood cell count and reduced lactate levels.
- Results show that breath-holding may delay fatigue and improve overall endurance during exercise, suggesting potential benefits for distance runners.
Effects of Zinc Oxide Nanoparticles (ZnO NPs) on Growth, Immune Responses and Histopathological Alterations in Asian Seabass (, Bloch 1790) under Low-Salinity Conditions.
Animals (Basel)
September 2024
Laboratory of Aquatic Animal Health Management, Department of Aquaculture, Faculty of Fisheries, Kasetsart University, Bangkok 10900, Thailand.
In the present study, Asian seabass (, Bloch) fingerings were used as an animal model to investigate the toxicological effects of zinc oxide nanoparticles (ZnO NPs) under 5 ppt estuarine conditions. The fish were exposed to 0, 1, 5 or 50 ppm ZnO NPs for 8 weeks. It was found that ZnO NP concentrations of 5-50 ppm negatively affected several growth rate parameters, such as the weight and total length of the fish.

The purpose of this study was to investigate the effect of whole-body cryotherapy (WBC) on acute recovery after a single high-intensity training day. Twelve elite professional male rowers from the national aquatic training base. They were randomly divided into a WBC group (n = 6) and a control group (CON group, n = 6).

Article Synopsis
- This study aimed to compare the accuracy of a hemoglobinometer that uses capillary blood samples with a clinical lab that uses venous blood samples.
- Conducted in Badalona, Barcelona, it involved 120 randomly selected participants over 18 years old who required routine blood tests.
- Results showed small differences in hemoglobin and hematocrit values between the two methods, but a strong correlation suggests that the Verio Q hemoglobinometer is effective for early anemia diagnosis in primary care settings.
Effect of Fluid Intake on Acute Changes in Plasma Volume: A Randomized Controlled Crossover Pilot Trial.
Metabolites
May 2024
Division of Exercise Physiology and Metabolism, Bayreuth Centre of Sport Science, University of Bayreuth, 95440 Bayreuth, Germany.
Plasma volume (PV) undergoes constant and dynamic changes, leading to a large intra-day variability in healthy individuals. Hydration is known to induce PV changes; however, the response to the intake of osmotically different fluids is still not fully understood. In a randomized controlled crossover trial, 18 healthy individuals (10 females) orally received an individual amount of an isotonic sodium-chloride (ISO), Ringer (RIN), or glucose (GLU) solution.
