Key result
Active recovery at 80-100% lactate threshold clears blood lactate faster than 40% or passive recovery.
Why the study?
There is no commonly agreed intensity or mode for clearing accumulated blood lactate after high-intensity exercise.
Does active recovery at higher intensities close to the lactate threshold improve blood lactate clearance compared to passive or lower intensity recovery after high-intensity running?
Comparison
Active recovery at 60-100% vs 0-40% of lactate threshold and passive recovery
Design
Experimental study measuring blood lactate clearance during recovery

May inform athlete recovery protocols; hypothesis-generating and requires validation before clinical adoption.

p-value: p=<0.05
Active recovery at intensities close to the lactate threshold clears accumulated blood lactate faster than passive or lower-intensity recovery.
Menzies et al. (2010) studied this question. Active recovery at higher intensities (60-100% of lactate threshold) vs. Lower intensities (0-40% of lactate threshold) or passive recovery was evaluated on Blood lactate clearance rate (p=<0.05). Active recovery at 80-100% of lactate threshold cleared accumulated blood lactate significantly faster than 40% of lactate threshold or passive recovery (P<0.05).
