  1. Metrics include sample size (N), peak maximum heart rate (peak fHmax), the temperature of peak fHmax (TPEAK), the temperature at which arrhythmias began (TARR), and thermal safety margin (TSM) as the difference between TARR and max environmental temperature (31 °C). Statistical results are from a one-way ANOVA.
  2. Significant P-values are bolded.
