|---|---|---|---|---|---|---|---|
| Bray et al. (2008) | 49 subjects (21,25±1,70 years), 35 women. | 3 min 40 seconds – teste Stroop or control | Fatigue, effort, pleasantness of the task, frustration, mood | Isometric handrip task EMG hand and wrist flexors Force recording |
Isometric handrip task – 50% MVC |
↔ Mental effort ↔ Fatigue ↔ Pleasantness of the task ↔ Mood ↑ Frustation ↔ RPE |
↔ Handgrip endurance performance ↔ Force ↔ EMG |
| Marcora, Staiano, Manning (2009) | 16 subjects (26±3 years), 6 women | 90 minutes– AX-CPT test or control | BRUMS Motivation |
Physiological and perceptual | Rectangular workload 80% of peak power output | ↑ HR ↓ [Gli] ↑ Fatigue ↓ Vigor ↔ Motivation ↑ RPE |
↔ RPM ↓ TE ↔ HR ↔ VS ↔ CA ↔ MAP ↔ VO2 ↔VE ↔ [Lac] |
| Bray et al. (2012) | 38 subjects (21,47±3,16 years), 23 women | 22 minutes – Stroop test or control | Visual analogue scale RPE |
Isometric handgrip force generation EMG hand flexors |
Intermittent maximum hand squeezes | ↑ Mental effort ↑ RPE ↔ EMG ↔ Fatigue |
↓ MVC ↔ EMG |
| Brownsberger et al. (2013) | 12 subjects (24±5 years), 4 women | 90 minutes continuous cognitive test | Visual analogue scale | Mean power output | Self-paced exercise RPE (11 e 15) | ↑ Fatigue ↔ HR ↔ [Gli] ↔ Motivation ↔ Mood |
↓ Power output |
| Pageaux, Marcora, Lepers (2013) | 10 subjects (22±2 years) | 90 minutes - AX-CPT test or control | BRUMS Motivation |
Time to exhaustion MVC |
Submaximal isometric knee extensor exercise | ↑ HR ↑ Fatigue ↓ Vigor ↔ Motivation ↑ RPE |
↓ TE ↔ MVC ↔ Amplitude e duração da onda M para o VL e RF. |
| Pageaux et al. (2014) | 12 subjects (21±2 years), 4 females | 30 minutes –Stroop or control | BRUMS Motivation |
HR [Lac] [Gli] Performance |
Time trial 5-km | ↑ HR ↔ [Gli] ↔ Fatigue ↔ Motivation ↓ Vigor ↑ RPE |
↓ Performance 5-km ↓ Running speed ↔ Pacing strategy ↔ [Lac] |
[Gli]: glucose concentration; [Lac]: lactate concentration; MVC: maximal voluntary contraction; CA: cardiac output; EMG: electromyography; HR: heart rate; MAP: mean arterial pressure; RPE: rate perception exertion; VE: ventilation; VO2: volume oxygen; RF: rectus femoris; RPM: rotation per minute; TE: time to exhaustion; VL: vastus lateralis;
