Table 1.

Muscle CP, lactate, pH and glycogen before (pre-training) and immediately after (post-training) the first training session consisting of 15 × 1 min knee-extensor exercise bouts, at an intensity eliciting ∼150% of peak thigh V̇_O2max, separated by 3 min rest periods

	Pre-training	Post-training
Muscle CP (mmol (kg DW)−1)	84 ± 3	19 ± 4§
	(70–92)	(4–33)
Muscle lactate (mmol (kg DW)−1)	8.3 ± 1.1	91.3 ± 10.5§
	(5.2–13.0)	(49.1–134.7)
Muscle pH (– log H+)	7.14 ± 0.02	6.88 ± 0.02§
	(7.02–7.21)	(6.82–6.96)
Muscle glycogen (mmol (kg DW)−1)	494 ± 45	133 ± 37§
	(289–647)	(41–281)

Values are means ± s.e.m. and range.

^§Significantly different (P < 0.05) from pre-training value.
