I recently upgraded my HR strap from a Soft Strap Premium (The black one is used to have for my Forerunner 230) to a HRM-Run (the red one) and it seems to have had a big impact on my Training Status,Training Load and Training Effect.
My usual weekly running routine will consist of nothing on Monday. On Tuesday a 4.5km run to work (mostly downhill with some flat) and the same in the afternoon to get home (mostly uphill with some flat). On Wednesday I will do a 6km flat run at 90% of my 5km pace. Thursday will be a repeat of Tuesdays running. Nothing on Friday. Saturdays and Sundays will be a 10km to 16km run at 80-90% max HR.
My training Status with my old HR strap was always at the higher end of 'productive', but with the new HRM-Run it's more in the 'recovery' or 'unproductive' areas for some reason.
My training load used to be in the 'Optimal' green section, but it now tends to be in the blue 'Low' area.
My (Aerobic) Training effect for Tuesday and Thursday morning runs used to be about 3.1, but now I only hit around 2.2, and the afternoon return runs were hitting 3.6, but now they're only hitting 3.1 if I'm lucky. I ran a 27 km trail run on Sunday and that only gave me a TE of 3.1 (to be fair it was almost 2 mins per km slower than my normal road pace though).
Does anyone know why there would be such a difference in all of these figures based on which HRM I'm using?
