An interventional study of Voluntary Hyperventilation and Post-Activation Performance Enhancement (PAPE) in Anaerobic Performance, Energy System Contributions and Hyperventilation, sponsored by Manisa Celal Bayar University. Completed at 1 site in Turkey (Türkiye). Open to male participants aged 18 Years to 25 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Manisa Celal Bayar University · Not applicable, Interventional, and Basic science
The purpose of this study is to investigate the independent and combined effects of post-activation performance enhancement (PAPE) and voluntary hyperventilation (HV) interventions on anaerobic power outputs, energy system contributions during a 30-second Wingate Anaerobic Test (WAnT).
43 studies on the registry are indexed under Hyperventilation; 6 are open to participants now.
This study's enrollment of 11 is below the median of 40 across 31 interventional studies indexed under Hyperventilation.
