Metabolic adaptation
VO2 peak was unchanged at 8 days but increased at 30 days of training.
Significant improvements in VO2 peak occur after 30 days of endurance training, which is important for enhancing overall fitness.
StrongSupportsmedium confidence
VO2 peak was unchanged from PRE (3.52 +/- 0.20 l/min) at 8D (3.55 +/- 0.20 l/min) but was increased (P < 0.01) at 30D (3.89 +/- 0.18 l/min).
Why this rating
Based on the study design and statistical significance.

- Mean response time to reach 63% of steady-state VO2 was faster at 4 days (34.9 +/- 2.4 s) and 9 days (32.5 +/- 1.8 s) of training compared to pretraining (38.1 +/- 2.6 s), and was fastest at 30 days (28.3 +/- 1.0 s).Strong
- Blood lactate concentrations were lower at 4 days and 9 days of training compared to pretraining, and were also lower at 30 days than at all other times.Strong
