International Physiology Journal invites high quality submissions across cardiovascular, respiratory, neurophysiology, renal, endocrine, metabolic, and integrative physiology. We welcome original research, reviews, and methods papers that deliver validated evidence and clear implications for physiological science or clinical practice.

Our editorial priorities focus on rigor, transparent reporting, and translational relevance. Submissions should explain how findings advance mechanistic understanding or improve physiological assessment and care.

• Cardiovascular and vascular physiology
• Respiratory mechanics and gas exchange
• Neurophysiology and sensory systems
• Renal, electrolyte, and fluid balance regulation
• Endocrine and metabolic physiology
• Exercise, muscle, and performance physiology
• Gastrointestinal and hepatic physiology
• Reproductive and developmental physiology
• Aging, stress, and adaptive physiology
• Systems, integrative, and computational physiology

• Short communications reporting high impact findings
• Technical notes on physiological monitoring or diagnostics
• Translational studies linking mechanisms to clinical outcomes
• Data or resource papers that improve reproducibility
• Perspectives on emerging physiology questions

Successful submissions present a clear research question, robust sampling design, and transparent statistical reporting. We value studies that demonstrate reproducibility and relevance to physiological science or applied outcomes.

Authors should explain novelty, document measurement protocols, and connect findings to physiological mechanisms or clinical implications.

• Clear measurement protocols and instrumentation details
• Sampling methods and participant context reported in detail
• Validation against established benchmarks or controls
• Appropriate statistical methods with effect sizes

Submissions undergo editorial screening for scope fit, study design quality, and data transparency. Qualified manuscripts move to single blind peer review with subject matter experts.

IPJ operates under an open access model to ensure physiology research is discoverable and reusable. APCs are applied after acceptance and support peer review, production, and archiving services.

Membership options and affordable APC waivers are available for eligible authors. Contact the editorial office at [email protected] for guidance.

• Scope fit confirmed for physiology research
• Measurement protocols and instrumentation details included
• Sampling design and participant context documented
• Data availability statement included
• Cover letter explains novelty and relevance

IPJ prioritizes submissions that demonstrate clear physiological endpoints, validated measurement protocols, and transparent statistical reporting. Manuscripts should explain how experimental conditions were controlled, how data were normalized, and how variability was addressed across cohorts or model systems.

• Describe measurement devices, calibration procedures, and reference standards.
• Report participant or model characteristics, including age, sex, and inclusion criteria.
• Define primary outcomes and prespecified analyses before presenting results.
• Provide effect sizes, confidence intervals, and model assumptions.
• Explain timing of measurements relative to interventions and recovery periods.
• Document environmental conditions such as temperature, altitude, or humidity.
• Include quality control steps for assays, sensors, and data cleaning.
• State how missing data were handled and justify imputation methods.
• Clarify normalization for signals such as heart rate, VO2, or pressure data.
• Provide protocol details that enable replication across laboratories.
• Report software versions and statistical packages used.
• Summarize mechanistic implications supported by the evidence.

IPJ expects clear ethics documentation and transparent data availability for all submissions. Studies involving humans or animals must include approval identifiers and describe welfare safeguards. Data sharing improves validation and long term reuse of physiology findings.

• Include IRB or ethics committee approvals and consent statements.
• Document animal welfare monitoring and humane endpoints.
• Provide data availability statements with repository links.
• Share code or analysis workflows when feasible.
• Describe restrictions on sensitive or proprietary datasets.
• Disclose conflicts of interest and funding sources.
• Note preregistration details if applicable.
• Report adherence to CONSORT, STROBE, or PRISMA as relevant.

Physiology manuscripts should document experimental design in sufficient detail to ensure reproducibility and clear interpretation. Describe model selection, sampling strategy, timing of measurements, and the rationale for primary outcomes.

• Define primary endpoints and specify secondary outcomes.
• Report calibration and validation for measurement devices.
• Describe control conditions, blinding, and randomization.
• Specify environmental conditions and protocol timing.
• Document normalization methods for physiological signals.
• Include power calculations or sample size justification.
• Report inclusion and exclusion criteria transparently.
• Clarify intervention dosing and exposure parameters.

Clear statistical reporting improves transparency and comparability across physiology studies. Provide complete method descriptions, report effect sizes, and define how variability was addressed.

• List statistical tests and model assumptions.
• Report confidence intervals and effect sizes.
• Explain multiple comparison or correction methods.
• Describe handling of missing data and outliers.
• Include sensitivity analyses when feasible.
• State software versions and analysis packages.

Ensure your manuscript highlights physiological relevance and connects results to mechanisms or clinical interpretation.

• State hypotheses and primary outcomes clearly.
• Summarize key methodological controls.
• Include clear figure captions and units.
• Confirm data availability statements.

Use this checklist to confirm methodological clarity and physiology reporting consistency before submission.

• Describe participant or model characteristics in detail, including sex, age, and inclusion criteria when applicable.
• Report experimental protocols with enough detail to allow replication across laboratories.
• Provide calibration details for physiological measurement devices and instrumentation.
• State primary endpoints and physiological outcomes clearly before presenting results.
• Include normalization methods for physiological signals such as heart rate, VO2, or blood pressure.
• Explain how environmental conditions such as temperature, altitude, or humidity were controlled.
• For cellular physiology studies, report culture conditions, passage numbers, and media composition.
• Describe anesthesia, analgesia, and monitoring protocols for animal or clinical studies.
• Report statistical models, effect sizes, and confidence intervals for key outcomes.
• Clarify how baseline measurements were obtained and how changes over time were calculated.
• Include information on randomization, blinding, and allocation procedures when applicable.
• Document compliance with ethical approvals and informed consent for human studies.

IPJ is committed to rigorous, transparent publishing in physiology research. We emphasize reproducible methods, clear reporting of experimental protocols, and ethical compliance across all article types.

The editorial office supports authors, editors, and reviewers with clear guidance and responsive communication. For questions about scope or workflow, contact [email protected].

We encourage continuous improvement in reporting practices and share updates that help the community maintain high standards in human and comparative physiology.
