Abstract

The purpose of this study was to examine the acute effects of the Training Mask 2.0 (TM) on performance (m), blood lactate, heart rate recovery (HRR), stroke volume (SV), cardiac output (Q̇), heart rate variability (HRV), and breath rate recovery (BRR) when used during short-term recovery. Methods: Seven trained males completed two interval training conditions (TM and Sham TM). Each condition consisted of five, 1-min, max effort rows with 3-min recoveries. The TM (or Sham TM) was worn during each 3-min recovery. A repeated measures 2x5 (condition x interval) ANOVA was used to determine significant main effects for condition or interval. Post-hoc analysis was conducted using a one-way ANOVA to identify differences in conditions or intervals with the Bonferroni adjustment. Results: There were no differences between TM and Sham TM conditions for performance (m) (p = 0.094), blood lactate (p = 0.495), HRR (p = 0.533), SV (p = 0.672), Q̇ (p = 0.775), or HRV (p = 0.158), while BRR was improved in the TM condition (p = 0.008). Conclusion: The use of the TM during short-term recovery does not improve rowing performance (m), blood lactate, HRR, SV, Q̇, or HRV during interval training. Contrary to anecdotal reports, the implications for the TM to enhance short-term recovery are not supported.
