Regression models for predictors of RPE and lactate at 30 W and at 35% VO2peak
| Effort predictor variables | 30 W F statistic (p value) | 35% VO2peak F statistic (p value) |
|---|---|---|
| Physiological RPE predictor model | ||
| Heart rate during 8 min exercise | 9.8 (p=0.002) | 4.1 (p=0.045) |
| Hypertension diagnosis (yes/no) | 6.4 (p=0.02) | 10.3 (p=0.003) |
| Lactate during 8 min exercise | 6.0 (p=0.02) | 4.2 (p=0.04) |
| HOMA-IR | 2.3 (p=0.14) | 0.8 (p=0.38) |
| Behavioral RPE predictor model | ||
| CES-D | 4.5 (p=0.04) | 3.2 (p=0.08) |
| HOMA-IR | 2.5 (p=0.11) | 1.5 (p=0.23) |
| Physiological lactate predictor model | ||
| Heart rate during 8 min exercise | 5.6 (p=0.02) | 8.9 (p=0.0002) |
| T2DM diagnosis (yes/no) | 6.2 (p=0.02) | 1.6 (p=0.26) |
Separate linear regression models were conducted for physiological predictors of RPE, behavioral predictors of RPE and physiological predictors of lactate during exercise at 30 W and at 35% VO2peak.
