Im interested i this as I have the same reaction. I’m 62 and can held my Max HR of 185 for 10 mins in my last race, no lactic acid.
I’m wondering if it an age thing, or wether its physiology.
what does this tell me about my AeT and AnT levels?
I am not very good at doing specific effort tests, but I have tons of anecdotal data from workouts and racing.
I am 51, and spend most of the year training for Ultra trail races. 80% of my ultra volume is at my endurance, aerobic pace.
in the late summer, I start to incorporate higher intensity work to prepare for skimo race season.
for the past 7 weeks I have been doing what I call my “indoor skimo workout”. I do this workout 2x per week( with 2 full days in between)
1. 10 min warmup
2. 20 mins at 10% incline
3. ME strength: 3×15 single leg box steps, 3×15 single leg lunges.(180 total reps)
I repeat #2 and #3 3 times without stopping. total of 1hr uphill running and 540 total reps of ME strength. takes about 1:45 to finish the workout with short cool down jog.
my question about AeT and AnT is this:
– the max HR I have ever reliably recorded is 175. I only see 175 when I am working extremely hard, and there needs to be a weather factor like extremely hot/humid. or extremely cold.
when I do my indoor skimo workout, by the 2nd run interval, I reach a HR of about 158-160…and I hold that HR for 2 sets of 20 min runs. if my HR goes higher than that, I begin to feel the slow buildup of lactic acid, but if I stay at 160, its comfortably hard but no lactic acid.
if I take out the extreme weather factor, and consider my age, my max HR is prob around 170. my LT run intervals are done at a HR of 160 with no lactic acid build-up. what doesn’t make sense to me is that seems to suggest that my LT threshold is 90% of my max HR. am I thinking about this wrong. or can that be right?
I will add that it takes me a long time to raise my HR to these levels. I seem to need extra time to get to these levels, and if I try to go too hard too soon, I’m panting like a dog and blowing up quickly. if I ease into it over 30-40 mins, I can hold 90% for a long time.
my last trail race of the season was a 6hr timed hill race up/down a ski resort. the climb up took about 1 hr. I was holding a HR of about 155 per 1 hour climb, and I did that 4 times. my PE during the climbs was about 80%( or the max effort I knew I could do 4 times). I did this before introducing the intervals described above.
for skimo, I am trying to raise my LT, but I’m not sure I am thinking about this right. any guidance would be appreciated.
