Heart rate recovery and its correlated cardiovascular recovery are important factors for athletes who need to perform at a high level with limited time to recover. The purpose of this study was to evaluate the effect of four different breathing protocols on heart rate (HR) and ratings of perceived exertion (RPE) in collegiate level hockey players. Participants (N=20, 10 male, M=21.6±1.6 years, and 10 female M=20.6±1.1 y ears) ran on a treadmill until 80% age-predicted max heart rate was achieved. Upon achieving the predetermined HR, participants recovered in a sitting position for two minutes, using one of the four breathing techniques (normal breathing, deep breathing, nose breathing, and controlled hyperventilation) for the first 30 seconds of recovery, followed by 90 seconds of regular breathing. HR was recorded every 30 seconds and RPE was recorded after two minutes of recovery. This procedure was repeated for each of the four breathing techniques on two separate days. Results from a repeated-measures one-way ANOVA, sphericity assumed, revealed no significant differences for females on post-exercise HR at all four time intervals or RPE. For males, significant differences were found for HR between breathing protocols at 30 seconds (F=9.18, 3, p≤.050) and 60 seconds (F=2.93, 3; p≤.05). Pairwise comparisons found post exercise heart rates for controlled hyperventilation significantly different from normal breathing (MD = -13.2 bpm), deep breathing (MD=-11.2 bpm) and nose breathing (MD =-6.9 bpm) at 30 seconds, and nose breathing significantly different from normal breathing (MD = -7.2 bpm) at 60 seconds. No significant differences were found for HR at 90 seconds or 120 seconds or for RPE. Results from this study indicate certain breathing techniques, particularly controlled hyperventilation and nose breathing, may result in faster HR recovery.
