Lactate distribution in the blood during steady-state exercise
. Med Sci Sports Exerc.
However at intensities between LT1 and second lactate threshold (LT2) (phase 2) the lactate production rate is higher than metabolizing capacity in the muscle and the lactate will appear in the blood (increasing the BL concentration), but with possibility of stabilization in steady-state exercise
. Above LT2 (phase 3), the muscular lactate production rate exceeds the systemic lactate elimination rate without attainment of steady-state during a constant work-load (Binder et al., 2008; Tscharkert and Hofmann, 2013).
The study also noted that Zumba is a good weight-control exercise because it is an interval training (going back and forth between high- and low-intensity workout) where you burn more calories during and even after workout, even more than a steady-state exercise
Therefore the HR-V[O.sub.2] relationship during non-steady-state exercise cannot mimic the relationship in steady-state exercise
as the oxygen consumption is reduced due to a decrease in exercise intensity while the HR remains high.
Figure 1 presents the percentage of the physiological parameter during steady-state exercise
compared to the maximal value of the respective physiological variable.
The magnitude of cardiovascular drift during the 2-hr bout of steady-state exercise
was not different between trials (p = 0.886).

(1996) Comparison of muscle near-infrared spectroscopy and femoral blood gases during steady-state exercise
Oxygen consumption values were averaged over a 5-min period during steady-state exercise
. Heart rate was observed using a Polar HR monitor and recorded at the 7 1/2-min mark.

Ischemic cycling studies use pneumatic cuffs placed proximally around both thighs, then inflate them to impede blood flow and [O.sub.2] delivery during steady-state exercise
Of relevance, only steady-state exercise
was performed in these studies and total work output was not assessed.
