- A dive into the physiological responses to O2- and CO2-tables in freedivers. [Journal Article]
- CONCLUSIONS: These results suggest that, in freedivers, O2- and CO2-tables offer a less mentally and physically demanding alternative to repeated maximal apneas, allowing greater variation in apnea training while still targeting O2 conservation and CO2 tolerance, respectively.

- Heart rate variability and cortisol responses to acute low- and moderate-intensity exercise in stress-related exhaustion. [Journal Article]
- CONCLUSIONS: These findings suggest altered physiological stress-system regulation in stress-related exhaustion and highlight the post-exercise period and exercise intensity as important considerations when tailoring exercise recommendations for this population. The study was retrospectively registered on 05/30/2024 at Clinical Trials.gov, with trial registration number NCT06429423.

- High-intensity interval training modulates the SIRT1-P16 pathway, inflammatory markers, and oxidative stress in the liver of D-galactose-treated male rats. [Journal Article]
- CONCLUSIONS: Concurrent HIIT attenuated D-galactose-induced hepatic molecular and biochemical alterations associated with aging. These effects were accompanied by changes in SIRT1-P16-related markers, improved redox balance, and reduced inflammatory responses, supporting the potential of HIIT as a non-pharmacological strategy for promoting liver health during aging.

- "Markers of benefit": the influence of physiological and physical factors on the relationship between slow-paced breathing and heart rate variability. [Journal Article]
- CONCLUSIONS: SPB improves HRV regardless of CRTI status. Those with higher baseline RR are more likely to obtain a significant improvement in HRV during SPB. SPB-based interventions may be introduced for the rehabilitation of military personnel following injury/deployment.

- The ascending aorta and vascular profile in recreational masters runners: a cross-sectional study. [Journal Article]
- CONCLUSIONS: These findings are consistent with modest, exercise-associated aortic remodelling rather than overt aortopathy in recreational masters runners over 40 years.

- Creatine supplementation effects on cognition, sleep, and menopause symptoms in response to six weeks of high-intensity resistance training in perimenopausal females. [Journal Article]
- CONCLUSIONS: In this exploratory analysis, CM combined with HIRT was associated with greater prefrontal oxygenation, higher sleep consistency, and fewer self-reported temperature sensitivity days relative to PLA in PERI females.

- Reliability and analytical validity of the MX3 hydration testing system during exercise in the heat. [Journal Article]
- CONCLUSIONS: Collected-saliva MX3 measurements demonstrated better between-day reliability and analytical performance than direct tongue measurements, although systematic disagreement with the reference osmometer remained. MX3 measurement performance differed between saliva sampling approaches, supporting further validation of the collected-saliva approach.

- Individual variability and predictors of responsiveness in physical outcomes following multicomponent physical training in older adults. [Journal Article]
- CONCLUSIONS: These findings suggest that multimorbidity, younger age, lower body mass index, and higher resistance training adherence are associated with greater responsiveness across multiple physical outcomes.

- Validity of triaxial accelerometer for estimating total energy expenditure in elite female university athletes: a doubly labeled water study. [Journal Article]
- CONCLUSIONS: The Cunningham equation provides reasonably accurate estimates of BMR. ACCTRI overestimated TEE by approximately 12% compared to DLW, thus support staff should consider this when supporting female runners.

- Multifactorial biomarker profiles in fatigued and non-fatigued post-COVID-19 patients: insights from a one-year follow-up. [Journal Article]
- CONCLUSIONS: Post-COVID fatigue was associated with persistent inflammation and genetic variation, supporting a multifactorial biological basis and highlighting hs-CRP as a potential marker requiring further validation.

- Evening high-intensity interval exercise attenuates the next-morning decline in flow-mediated dilation in healthy young men. [Journal Article]
- CONCLUSIONS: A single bout of HIIE attenuates the morning decline in endothelial function. These findings suggest that the vascular benefits of exercise extend beyond the immediate post-exercise period and may influence the diurnal pattern of endothelial function.

- Does a dedicated optimal power phase enhance performance outcomes in trained athletes? A comparison of periodized maximum strength and strength-power training. [Journal Article]
- CONCLUSIONS: Both maximum strength and combined strength-power regimens elicited improvements in maximal strength and selected power measures, while isokinetic training was less effective. The findings suggest that, over a prolonged period, no statistically detectable superiority of either complete program can be established.

- Cardiac autonomic and hemodynamic responses to two-stage cycling and post-exercise recovery with partial blood flow restriction in young males. [Journal Article]
- CONCLUSIONS: BFR modifies cardiovascular regulation during two-stage cycling and recovery and induces sustained autonomic shifts toward reduced parasympathetic and increased sympathetic modulation, largely independent of exercise intensity. Altered recovery kinetics following cuff release highlight the importance of careful monitoring during the recovery phase when applying BFR.

- Side differences in NIRS-derived muscle oxygen saturation during treadmill running. [Journal Article]
- CONCLUSIONS: No systematic differences between SmO2 response between the legs were found. However, wide limits of agreement suggest that individual side differences may exist. A single NIRS device may sufficiently reflect bilateral SmO2 responses at the group level, while individual side-to-side-comparisons should be interpreted with caution.

- The effects of different exercise approaches on muscle mechanical properties, strength, and jump performance: a randomised controlled trial. [Journal Article]
- CONCLUSIONS: Four weeks of exercise produced outcome-specific responses without demonstrating modality-specific changes in passive muscle stiffness or thickness or superiority among active interventions.
