When Ag* was present, a color change (absorbance variation, ΔAbs) of the solution is detected at a fixed wavelength (655 nm) by an optical chip docking system and registered by a computer. The amount of saxitoxin, present in the sample (or standard), that generates the variation of the intensity of the color, will be directly proportional to the concentration of the analyte in the analyzed solution. Indeed, the absorbance response increased proportionally to the enzymatic product and to the concentration of saxitoxin in the range of 3.5 × 10-7-2 × 1

The measured loaded-trial total (1310±153 mls O2/kg) was slightly under-predicted by the Minimum Mechanics equation (-2%, 1289±22 mls O2/kg) and over-predicted by the Pandolf equation (+13%, 1463±32 mls O2/kg). Computational comparisons for hypothetical trials at different constant speeds (range 0.6-1.8 m/s) on variable-gradient loop courses revealed between-equation prediction differences from 0 to 37%. We conclude that treadmill-based predictions of free-walking field energy expenditure are equation-dependent but can be highly accur
