What the study found
HRV increased within the group training three times weekly, but the study did not find a significant interaction between the two schedules.
Participants and protocol
Twenty-seven male student-athletes completed twelve alpha-band neurofeedback sessions under two weekly-frequency protocols. EEG and HRV were recorded throughout.
What this cannot establish
A within-group change does not establish that three sessions are superior to two or that neurofeedback improves athletic recovery. The abstract reports no untreated comparison group or race-performance outcome.
