Key result
The discontinuous and continuous protocols yielded similar VO2max values (56.8 vs 55.8 ml.kg-1.min-1), demonstrating that a VO2 plateau is not a prerequisite for defining VO2max.
Why the study?
Does a continuous exercise protocol yield similar maximal physiological responses and VO2max criteria achievement compared to a discontinuous protocol in young males?

Continuous protocols may suffice for VO2max testing without plateau requirement in young males; leaves open broader validation.

Absolute Event Rate: 56.8% vs 55.8%
p-value: p=< 0.05
A VO2 plateau is not a prerequisite for defining VO2max, and secondary objective criteria like RER and lactate in combination are more reliable indicators.
Duncan et al. (1997) studied this question. Discontinuous protocol (DT) vs. Continuous protocol (CT) was evaluated on VO2max (ml.kg-1.min-1) (p=< 0.05). The discontinuous and continuous protocols yielded similar VO2max values (56.8 vs 55.8 ml.kg-1.min-1), demonstrating that a VO2 plateau is not a prerequisite for defining VO2max.
