Redikus – I can also help – drop me an email.

Cheers, Jon

Fisherboy – you are welcome to speak to me too if you like – just to keep things even – coaching is the new doping! haha

Do you mean skills training or fitness training?
If it is fitness training, then no point really having someone local. Almost all training is given over the net these days.

I race at a high level and have had testing done with LabMonkey. I can recommend him, top bloke and knows his stuff.

Thanks Matt – there is a lot of ‘love’ being chucked about on this thread tonight!

Matt, how is the racing going at the moment? It must be about the time for your regular lab beasting and pinch an inch session?

Malc – I have just seen your email – I will respond properly soon.

If you meant ‘coaching’ in regard to performance analysis and training plans etc I can help you out – just give me an email (in profile).

Cheers, Jon

Zipp 303 carbon tubs – the perfect compromise between light and aero – I have some are they are awesome!

But if you want to win points – don’t buy wheels, buy a decent coach – or as someone said earlier – learn to sprint.

iOS5 is great on a 4S

I am having a PIE, chips, eggs and beans for tea thanks to this tread!

Are you meant to have ‘sum Col A’ in the first formula – as this has nothing to do with your calculation?

Thanks everyone – I appreciate your comments and I will look elsewhere.

Take them to A+E – right now. Go.

Bored.

Jock – thank you – that has worked perfectly!

spoon – shallow threads work for me… and I have spacers! cheers

B17 – ‘anaerobic capacity’ is meant in an energetic context – so the ability to supply energy to the muscle without requiring atmospheric oxygen. Although this could be associated with the ‘strength and power’ of rugby… (both use phosphocreatine in the muscle for example) they are still not really the same thing with regard to cycling type exercise.

If you make a ‘maximal’ effort on the bike you will use all of your phosphocreatine up in ~8 seconds… as with 100 m runners as they tend to be slowing down form ~80 m. But the 400/800 m guys need to be able to deliver maximal ‘aerobic power’ and to sustain as high a percentage of their ‘anaerobic metabolism’ (different to capacity) for the race duration. The difference in the muscle mass of 100 vs. 400/800 m runners may show you the difference?

B17 – I have a little over 1000 papers on this stuff… I am just finishing my PhD at the moment… it is due in next Friday.

Send me an email to jon [at] rstsport [dot] com and I may send a few things back your way – but it will all be mechanistic stuff – perfect for geeks!

Power output full stop is complicated as it jumps about so much (even on the road) – then consider off road (pedal/not pedal) and the constant change of pace, inclination, cornering etc… its all over the place. Then consider the lag in HR… you have nightmare making sense of everything as your HR only tells half the story.

But simply – raising power or speed for a given physiological effort (this could be HR) is the aim… how you do this best depends upon what part of your physiology is causing the performance bottleneck.

B17 – that would sound about right. But of course, I don’t know at what percentage on HRmax your FTP occurs at so I can’t be more specific.

Your FTP would roughly equate to the highest CONSTANT speed (or power) at which your HR will stabilise. Above this ‘effort level’ HR increases as a function of power and time – i.e., cardiovascular drift… or you have overloaded your ‘aerobic’ type I muscle fibres… they can’t work any harder… you need to recruit type II fibres (the anaerobic ones) and these need the enzymes I mentioned earlier to work efficiently. Lack of enzymes means your HR increases faster (as you have to recruit proportionally more of these less efficient fibres to maintain the effort) and so you have to stop riding so hard sooner (as you hit HRmax).

interested to hear more Labmonkey!

Oh god… look what I have started!

Can HR zones be related to work outs targeting capillary/mitochondria vs enzymes/glcolysis?

In theory – Yes – but traditional HR ‘zones’ are in essence related to ‘aerobic’ energy transfer and so work best during ‘endurance’ type exercise – the type that increases capillary density and mitochondria.

More intense exercise is required to stimulate enzyme production, and by extension, anaerobic glycolysis.

FTP has an ‘aerobic’ and ‘anaerobic’ component – the former has by far the largest ‘capacity’ but the latter tends to be where the gains can be made in most trained individuals.

EDIT: If you for example knew your time to exhaustion at a range of exercise intensities – for example 500W, 400W, 200W – it is possible to make a good guess which of these parts of your physiology is likely holding you back. This is because you can mathematically model the relationship between the imposed power output and the time to exhaustion – this then provides a value for the combined ‘aerobic capacity’ (similar, but a little lower than FTP) and the ‘anaerobic capacity’ also. The relative proportion of each indicates which system is strongest.

ps. sorry ro5ey.

[sorry – made a mistake there – time to exhaustion at a given time makes no sense – well it is quite obvious]

I do know how this is possible through specific workouts which target my threshold power. and i didn’t need to know my … capillary and mitochondrial density, capacity for glycolysis and haemoglobin concentration

Generic work outs performed close to threshold power will likely increase threshold power… simple really.

But, lets say you have a low enzyme density – and this is the weak link to your FTP – then some work outs target the enzymes specifically will increase your FTP more than doing your ‘specific’ FTP work outs.

A lab can tell you specifically what the weak link in your system is – or you can essentially make an educated guess from your performance time at different power outputs.

Well I enjoyed labmonkey’s post … ty

Thanks.

ps. Geek corner is closed. Unless encouraged further.

err.. WTF!

To do this you must understand the physiological determinants of FTP

do i?

Could you bake a cake without knowing the ingredients?

2 x 20’s work well… continue.

(getting geeky) I have wondered how you maintain/improve your FTP throughout the winter

To do this you must understand the physiological determinants of FTP – that is the ability to transport oxygen to the muscle (so essentially haemoglobin concentration), and the ability to use that oxygen within the muscle. The latter is the important part as you can’t really alter the former without having a good doctor or moving house.

Four things make a difference here… capillary and mitochondrial density within the muscle (generally increased with endurance training) and oxidative enzymes and the capacity for glycolysis (generally increased with interval training). You can kill the same bird* with many stones.

ps. Pete Reads book was written in the 1980’s… scientific understanding has moved on somewhat since then… although human physiology has not evolved much since that time.

*no birds were harmed in the writing of this post.

Yep. I have emailed them in the past and had no response too.

What the hell was that all about? Haha

AW – I am an exercise physiologist and cycle/triathlon coach – feel free to drop me an email if you want to chat about training/coaching etc.

If God hatched from an egg. How did the egg come into being?

+1

(sorry, couldn’t resist)

Wise words Herman shake.

That will do me for tonight. Happy arguing discussions.

Maybe we should have a simple YES or NO answer count up?

It is very important… as Science can’t tell us which came first… therefore where did the first ‘common ancestor’ come from…?

(I am a man of science, and I do not believe in god).

How does knowing the ‘common ancestor’ of chicken important to our life?

Man of science … hmmm … to answer your question … even until your turn carbon you will never find that answer of Chicken or Egg.

I think you may* be missing my point.

I was not trying to prove or disprove the existence of god, quite the contrary in fact… I was implying that science does not have all the answers, and it is unlikely it ever will… humans will kill each other well before then.

Religion and/or greed will see to my latter point.

Why is the chicken important? If you go far enough back… to the ‘primordial soup’ – the synthesised amino acids (from water, carbon dioxide, methane, hydrogen and ammonia) by the suns ultraviolet radiation, which created the first replicating chains of molecules… which would have been the ‘common ancestors’ to both the chicken and the human.

*if I am wrong I apologise

Chicken or Egg?

Is that important?

Free range or organic? I don’t mind either

Chicken or Egg?

I don’t believe in god… but where all of this ‘stuff’ came from to make the Universe and to allow for evolution is somewhat of a mystery.

..If you sign up for it and do it I’ll give you £50 as a start. Let us know.

STW generosity at its best… I can’t afford £50… but post up a photo of you on your first day and I will chuck a few quid your way too!

Go for it mboy… you won’t regret it!

Kit – The life of a PhD student is great… enjoy!

mboy – come on then what course do you want to do? (if you have said already please ignore the question).

If it is something that will open more doors in the future then go for it… if it is simply just a ‘fun’ subject to fill some time… then maybe it is not worth the debt.

I want back to Uni at 26 to study sports science, did well, got a funded PhD in exercise physiology… hand in date is 22 days away… now I get paid to teach, to do research, and to do consultancy type activities… Uni had been good to me (I am 32 now).

My previous life – well I managed a bike shop.

If I am honest, despite a few blips… I have had a great life so far… doing jobs that I love has been a big part of that… we spend so much time at work that doing a job you like is very important.

I would say to anyone that is in a job they hate, or can’t find a job in these tough times to consider University… money is tight, but you learn to budget and end up living just fine… go for it!

Sorry LabMonkey I didn’t get there in time – someone else must have used it

Is someone else on STW stealing jcrompton’s codes? shame on you!

I echo mchlptcher’s comments – I have a non UST black chilli tyre working fine as tubeless – it is more faff to get it to seal but it is working just fine now that it has.

I also have 2 x UST 2.2 (not black chill) going spare… £50 posted for the pair anyone?

I love my job – exercise physiologist – I am very lucky!

Good question – I have been wondering the same.

Maybe it has something to do with the ‘handmade in Germany’ label?

me too
