Note: Omnibus tests indicated no significant order effects, all p’s > .05. Omnibus tests indicated significant stage (baseline, 4-2-4, and 5-5) effects and are represented here. High frequency heart rate variability (HF-HRV). Respiration rate was measured in breaths-per-minute (BPM). Heart rate measured as the number of beats in 60 seconds (HR). Root mean squared of the successive differences between adjacent N-to-N peaks measured in ms (RMSSD). Standard deviation in N-to-N interval measured in ms (SDNN). Low frequency heart rate variability measured in ms2 (LF-HRV). Low frequency to high frequency ratio measured in ms2 (LF/HF Ratio). Very low frequency heart rate variability measured in ms2 (VLF-HRV). The number of interval differences of successive N to N intervals or heartbeat intervals greater than 50ms divided by the total number of NN intervals yielding a percentage (pNN50). Inter-beat-interval measured in ms (IBI). Abdominal Respiration Amplitude measured in volts (ARA).
