“…Pain was measured before the beginning of the test (PAIN 0'), in the minute 2 (PAIN 2'), in the minute 4 (PAIN 4') and then at the end of the test in the minute 6 (PAIN 6'). The OMNI scale 20 was used to evaluate rating of perceived exertion (RPE), with values ranging from 0 to 10. The measurement of RPE was performed during the minute 2 (RPE 2'), minute 4 (RPE 4') and soon after the end of the test in the minute 6 (RPE 6').…”

“…This category metric contains a rating range from 0, "extremely easy," to 10 "extremely hard". 73 Thermal sensation was obtained with the novel OMNI Thermal Sensation Scale (Appendix C) which contains verbal descriptors from the Gagge thermal sensation scale 20 and numerical categories ranging from 1, "comfortable," to 5 "very hot". Perceptual strain was determined by the equation: PeSI = 5 * [(TS t -1) / 4] + 5 * (PE t / 10); where TS = thermal sensation, and PE = perceived exertion.…”

Fire suppression and rescue is a physiologically demanding occupation due to extreme external heat as well as the additional physical and thermal burden of the protective garments. The hot environment challenges body temperature homeostasis inducing heat stress. Accurate field assessment of hyperthermia is complex and unreliable. Purpose: The present investigation developed a perceptually based hyperthermia metric to measure physiologic exertional heat strain during treadmill exercise. Methods:Sixty-five (28.88 ± 6.75 yrs) female (n=11) and male (n=54) firefighters and non-firefighting volunteers participated in four related thermal stress investigations performing treadmill exercise while wearing thermal protective clothing in a heated room. Physiological and perceptual responses (i.e. body core temperature, perceived exertion, and thermal sensation) were assessed at baseline, 20-mins exercise, and at termination. Results: Perceived exertion increased from baseline (0.24 ± 0.42) to termination (7.43 ± 1.86). Thermal sensation increased from baseline (1.78 ± 0.77) to termination (4.50 ± 0.68). Perceived exertion and thermal sensation were measured concurrently with body core temperature to develop a twodimensional graphical representation of three "colored" exertional heat strain zones. Each exertional heat strain zone was representative of a range of mean body core temperature responses such that green incorporated 36.0 to 37.4°C, yellow incorporated 37.5 to 37.9°C, and red incorporated 38.0 to greater than 40.5°C. Conclusions: A perceptual hyperthermia index (PHI) was developed using ratings of iii perceived exertion and thermal sensation. The PHI can provide a quick and easy momentary assessment of the level of risk for exertional heat strain for firefighters engaged in fire suppression and rescue. This metric may be beneficial in high risk environments that threaten the lives of firefighters.

“…It seems unlikely that the CNS performs this same calculation based on the sheer number of variables and parameters needed, but it may not need explicit knowledge of all these quantities to modulate the CoT. For example, the whole-body metabolic rate correlates fairly well with perceived exertion [40], which the nervous system could use to calculate an analogous CoT if the speed of the centre of mass was known. Some modulation could also take place at the peripheral level, without direct involvement of CNS.…”

Evaluation of the minimum energy hypothesis and other potential optimality criteria for human running

et al. 2011

A popular hypothesis for human running is that gait mechanics and muscular activity are optimized in order to minimize the cost of transport (CoT). Humans running at any particular speed appear to naturally select a stride length that maintains a low CoT when compared with other possible stride lengths. However, it is unknown if the nervous system prioritizes the CoT itself for minimization, or if some other quantity is minimized and a low CoT is a consequential effect. To address this question, we generated predictive computer simulations of running using an anatomically inspired musculoskeletal model and compared the results with data collected from human runners. Three simulations were generated by minimizing the CoT, the total muscle activation or the total muscle stress, respectively. While all the simulations qualitatively resembled real human running, minimizing activation predicted the most realistic joint angles and timing of muscular activity. While minimizing the CoT naturally predicted the lowest CoT, minimizing activation predicted a more realistic CoT in comparison with the experimental mean. The results suggest a potential control strategy centred on muscle activation for economical running.
