Ironman) The photo is from a Long Distance Event Swimming in the North of Spain (8,4 miles=13,5
km), I´m the guy who wears the speedo fast skin, and the girl in front of mine is my girlfriend.
I'll check it out. I have several spanish speaking friends. Maybe they can translate for me.

It´s very interesting for me to know the terminology for treshold in England, USA, Australia
and others.
My director´s doctorate is Alejandro Lucia, colaborator with Noakes.
I use LT as "significant increase in lactate concentration in blood from rest values" Many
investigators situate this point near 2mMol/L, but I prefer to individualize for each subject. In
bpms is something like 140 bpm for cycling (in my case 118 bpm)
OBLA is the intensity of exersice where the lactate concentration in blood can not be "cleaned",
Mader et al situate OBLA in 4 mMol/L. In bpm, something like 175 bpm (in my case, 154 bpm)
In OBLA breathing is very fast and superficial, In LT breathing is easy and deep.
Is it normal now?
It seems a bit closer but I'm still having a hard time.
According to the numbers here you place the athletes above a point were lactate is
accumulating in the stream. 75% of the time for the swim, 47% of the time for the bike and
15% fro the run. Lets these athletes did around a 5 hr 1/2 IM, for easy figuring. 30 min
swim 3 hr bike and 1 1/2 hr run. That woudl put them at a point of accumulating lactate for
22.5 mins in the swim, 84.6 mins in the bike and 13 min in the run for a total of 120 min or
two hrs. Roughly 40% of the entire race was run accumulating lactate. These numbers alone I
woudl think would be feasible, something along the lines of an interval workout were you
were allowed a recovery period. Unfortunately this is a race and as you stated a good
portion of the rest of the time was spent at (LT to OBLA) During this transition period the
rate at which the lactate can be "cleaned" is considerabbly slower than the rate during an
interval recovery. I suppose that it is possible that an athlete play the line very closely.
In other words running at 101% (OBLA) for 5 minutes and the 99% (OBLA) at 5 minutes. I just
have a hard time beleveing that is possible for an endurance race such as a 1/2 IM. I'll
check out the study adn see what else I can dig up.

Hi, i´m a spanish triathlete, I´m doing the bachelor in Physiology of triathlon. I´m researching
about heart rate in Long Distance Triathlon.
In a half Ironman, 5 triathletes used a heart rate monitor (Polar s-810)3 weeks later to develop 3
field tests to determinate lactic treshold (LT) and Onset on Blood Lactate Acumulation (OBLA) to
establish 3 zones of intensity. Phase I (from rest to LT) or aerobic phase, Phase II, from LT to
OBLA, or transition phase, and phase III, from OBLA to maximum, or anaerobic phase.
In Half Ironman, the triathletes were in phase I of swimming 1% of time, 4% in phase II and 75% in
phase III. In cycling 4% in Phase I, 49% in phase II and 47% in phase III. In running, 5% in phase
I, 80% in phase II and 15% in phase III
