In this blog, we are going to provide a little detail for athletes and practitioners on how to interpret changes in blood lactate parameters and profiles derived from serial laboratory-based lactate threshold assessments. These assessments typically involve exercising initially at a very low workload, considerably below the aerobic threshold, with heart rate and blood lactate concentration recorded prior to an increase in workload every 3-4 minutes (although these ‘steps’ can be longer). These steps are repeated until exhaustion. Expired gases may be collected throughout, and these can provide insight into movement economy, substrate utilization, and maximum oxygen uptake (VO2max). The tests are typically performed for (i) training zone identification and (ii) monitoring adaptations to training.
Classic rightward and leftward shifts
Below we have a textbook rightward-shift in the blood lactate vs. power output curve, which we...

We’ve really been enjoying watching the return of road racing after the pandemic (or somewhat ‘after’), like we're sure many of you are too, and are particularly enjoying watching the athletes at Le Tour grinding up the Alps and Pyrenees in big gears and at massive power outputs. Hill reps are a common part of many endurance training programs, whether that be for running, cycling, or triathlon, and at Endure IQ we are big fans of riding up hills and doing specific overgearing work on the trainer in preparation for a long-distance triathlon (in fact, we dedicate a whole module to this type of training in our three disciplines in our online course LDT 102). We thought now was as good a time as any to review some of the key studies in this field, and whether the available research backs up this type of training prescription.
Specific strength training for endurance athletes
We call this type of work –...

How “easily” we can perform a specific movement or task is a critical determinant of Long Distance Triathlon (LDT). For example, to run a 3-hour marathon (an excellent running time in an Ironman Distance Triathlon) the average pace is 4:16 min/km. There are many athletes who can run 4:16 for 1 km; the issue most athletes face is that they simply can’t do it easily enough to do it 42 times back-to-back. In their online course Endure IQ LDT 102: Training Program Fundamentals for Long Distance Triathlon, Dan and the team at Endure IQ go through the rationale regarding how, for LDT, it’s likely better to focus on “specific strength” rather than lifting heavy weights in the gym. However, gym-based exercises where the main focus is to improve movement efficiency are still likely to be very beneficial, and, moreover, can be completed is less than 20 minutes; a key consideration for the time-poor long distance...
