Table 1.
Physiological responses to constant workload trials at exhaustion during large (BIKE) and small (KE) muscle mass leg exercise.
| BIKE (85% of peak workload) |
KE (85% of peak workload) |
|
|---|---|---|
| Time to Exhaustion (s) | 378 ± 30 | 547 ± 22.7* |
| Workload (W) | 238 ± 8 | 52 ± 4* |
| Oxygen Consumption (L/min) | 3.1 ± 0.1 | 1.8 ± 0.2* |
| Carbon Dioxide Production (L/min) | 3.4 ± 0.2 | 2 ± 0.2* |
| Ventilation (L/min) | 116 ± 9 | 84 ± 6* |
| VE/VCO2 | 34.9 ± 1.9 | 42.6 ± 0.9* |
| Heart Rate (bpm) | 166 ± 4 | 130 ± 5* |
| RPE | 10 ± 0 | 10 ± 0 |
Values expressed as mean ± S.E.M. VE/VCO2, ventilation relative to carbon dioxide production. RPE, rating of perceived exertion.
