Figure 4. Kinematic measurements and cognitive performance during tasks that induced physical fatigue (PF), mental fatigue (MF), or both types of fatigue (PMF). (A) Training impulse (TRIMP) during tasks that induced PF or PMF. (B) Heart rate (HR) during tasks that induced PF, MF, or PMF. (C) Cognitive performance during an AX-continuous performance task that induced MF or PMF.
