  1. Exhaustion in T2D (n = 9) and ND (n = 10).
  2. T2D = individuals with type 2 diabetes; ND = individuals without type-2 diabetes; *p < 0.05 in relation to corresponding results for T2D; ‡ p < 0.05 in relation to the thresholds (LT, TV, HRVT RMSSD and HRVT-SD1). No differences were observed within groups for the methods to identify anaerobic threshold intensities.
