What´s really important on intreval training is the total average pace and that teh total number of intrevals is done with with a closed amplitude.
If you run 60s but also 55s that is 57.5 average, but it´s open amplitude
If you run 58.5s and 56.5s that is also 57.5 average but it´s closed amplitude and it´s better.
Is closed amplitude important only in the race-specific zone, or is it also important for intermittent training in the "special" pace zones? I imagine if you're training for a 1500m that you will race at 57.5 per 400, the closed amplitude session is better. But if you're training for a 5000m at 63 per 400, does a "special" interval session of 400m starting at 60 and working down to 55 make sense?
