compensation point

n
(Botany) botany the concentration of atmospheric carbon dioxide at which the rate of carbon dioxide uptake by a photosynthesizing plant is exactly balanced by its rate of carbon dioxide release in respiration and photorespiration

Although this has not been explicitly expressed, you seem to be apprehensive about agreeing to receive a retainer as you consider that you will be no better than your friend from a compensation point of view.
On the other hand, the gap between AT and the respiratory compensation point (RCP), point of exercise intensity above which only anaerobiosis occurs, the training zone, may become narrowed or difficult to determine.
Using PhotosynAssitant[R] software, maximum photosynthesis ([A.sub.max]), PAR at [A.sub.max], transpiration at [A.sub.max], conductance at [A.sub.max], light saturation point ([L.sub.sp]), light compensation point ([L.sub.cp]), dark respiration ([R.sub.d]) and quantum yield efficiency (IS) were determined for each replicate curve and means were calculated.
Each completed: a) an IET to exhaustion on a treadmill for the determination of the respiratory compensation point (RCP), [??][O.sub.2max], peak treadmill speed (PTS) and energy system contributions; and b) a 10-km time trial (T10-km) on an outdoor track to determine overall endurance performance and pacing.
Estimated times to exhaustion and power outputs at the gas exchange threshold, physical working capacity at the rating of perceived exertion threshold, and respiratory compensation point. J Appl Physiol Nutrit Metab.
The level of ventilation at a given CO2 output determines ventilatory efficiency.29 Ventilatory efficiency is a useful index for assessing patients with heart and lung disease.30 Increase in ventilation(VE) to increase in CO2 output (VCO2) is also an established index reflecting the severity of ventilation perfusion mismatch in heart failure patients.13 Traditionally an incremental exercise testing to a symptom limited maximum has been used to obtain the VE/VCO2 slope.13,29,30 VE increases in tight relationship with the increase in VCO2 during an incremental exercise until the near maximum level i.e ventilatory compensation point. Although slope becomes steeper above the ventilatory compensation point, slope is quite linear below this point.
We calculated several parameters from the curve adjustment: Apparent Quantum Efficiency (AQE), Light saturation Point (Psat), Light compensation Point (Pcom), Dark respiration (Rd), and the Maximum C[O.sub.2] Assimilation (Amax).
The average error of rotation angle dependence on the position of the first compensation point is shown in figure on bottom.
The light compensation point ([Q.sub.o]) was calculated
Light compensation point, light saturation point, and maximum Pn for each experimental unit were calculated or derived from the fitted equation.
