Do metabolic “thresholds”/ sudden breakpoints exist? Is there an on/off switch in glycolysis or the LD enzyme? Is there an on/off switch on La diffusion or a “passage” from aerobic to anaerobic metabolism in the muscle fiber? Is this what blood La behaviour tells us?

@lime_crush @seresartur @feelthebyrn1 @JDruns I highly suggest this thread on “thresholds”. All this discussion (including the unexplainable occurrence of LT1 at such high HR values) would be viewed in a different manner

@GregLJMU Dear Professor Atkinson, I have been trying to reach out to you through this email greg.atkinson@tees.ac.uk but it cannot be delivered for some reason. Is there any other way I could reach out to you? I have a few questions regarding interindividual variability.

@StrengthDebates @sid_eats_moves @kdtimms25 @BradSchoenfeld Plus, there is no selective fiber type recruitment depending on the speed of movement! If you explosively toss a ping pong ball you will hardly recruit any type II fibers (due to the minimal resistance).

@StrengthDebates @sid_eats_moves @kdtimms25 @BradSchoenfeld In this recent review the authors discuss how low load RT leads to similar gains as high load RT. The most likely mechanism appears to be the recruitment of higher threshold motor units (including type II) as fatigue is reached.

@SeanSeale @johngetstrong I recommend this point/counter point published in 2008 about whether SV increases or decreases with increments in exercise intensity. Of note, no zone (or “threshold”) has any effect on this.

@bensmithlive This is not true. “Real hydration” requires only water. The sodium plus glucose concept started when Na/Glucose cotransporters were discovered in the gut. The premise is that sodium enhances glucose absorption. This has nothing to do with Hydration (water volume)

@SamueleMarcora @MichaelMindrum Exactly! Twin studies do show that ~50 of individual differences in adipose tissue is explained by genetic differences. Heritability index: 0.50

@MichaelMindrum @SamueleMarcora I believe the CIM is poor and doesn’t explain many aspects of weight gain. One of my professors is interested in genetics of obesity and claims that the brain is the locus (behaviour); some people just eat more than others. This is closer to the energy balance model.

@MichaelMindrum @SamueleMarcora What if the excess energy is mostly fat and not carbs. Where would it be stored?

@MichaelMindrum @SamueleMarcora Urine contains around 0.01 mmol of fatty acids per litter. Given that a normal person urinates about 1.5-2 litres a day, I doubt this 0.015 or 0.02 mmol of fatty acids should be considered as fat storage or disposal….

@DrRajacobs Thank you for the comment! I agree! As a PhD student (2nd year), with no published articles on lactate metabolism, (with all due respect) I don’t think I have the academic “power” to suggest a replacement for a universal term that the mighty Wasserman coined.
