jwmlee – I am an exercise physiologist and endurance coach and so I might be able to help you out a little with your training – however, I am out *working* in Spain at the moment and I am about to head out on a training ride with some clients so I don’t have time to get into a long conversation on here right now – if you are interested, drop me an email and I will get back to you later. Cheers, Jon

Do it, you won’t regret it. Buy what suits your needs best – lots of wheels, then buy a crank/pedal system, if you just want one set of wheels, then a hub based system is a good option too.

Calibration ensures the data os consistent from day to day – very important.

It is not commuting admittedly, but I train all the time, that means all winter, on my race road bike – so full dura ace, full carbon rims, tubular race tyres – the full shebang! I ride because I love riding and I wouldn’t want to ride a piece of shit and have something nice sitting gathering dust. If I had to commute, I would ride something nice every day.

R(E)R is the respiratory exchange ratio – it can be used to give a rough estimate of your carbohydrate to fat (and a little protein) energy use (from the O2 consumption and CO2 production from the muscle).

VE is your minute ventilation – the volume of air you are respiring per minute

VE/VO2 is the ventilatory equivalent for oxygen uptake – it is used to identify ventilatory thresholds – like the gas exchange threshold… the numbers for this actually don’t mean anything, the experimenter is visually looking for changes in the VE/VO2 and VE/VCO2.

If you want a description of more of the results drop me an email.

njee20 – Everything I do is from pulmonary gas exchange data (correlated to power output, and converted to HR [if needed]). So you get the precise gas exchange thresholds, VT1 (which is very similar to the lactate threshold) and VT2 (which is roughly equivalent to the functional or anaerobic threshold), exercise economy/efficiency (the amount of O2 needed to increase the power output by 1 W) and the classic VO2max.

Blood lactate measurements are OK, but you get values at each stage, say 50W, 100W, 150W and so a measurement can only be attributed to a stage range, rather than a power output. With breath-by-breath gas exchange data you get a value per breath, which working maximally can be 100 or more breaths per minute – the temporal resolution is therefore far far greater.

plodtv – please send me an email.

Edit: I am an exercise physiologist and endurance sport coach and I can provide physiological testing and such like if required. Email in profile for anybody who is interested.

I can do pain in Aberystwyth too…

Does insulin sensitivity = ‘fitness’? No.

Does the individual with the ‘best’ insulin sensitivity win the race? No.

Will it help diabetics? Probably.

Will in make you faster on a bike? Unlikely (especially if you stop ‘normal’ training).

Joe, I am an exercise physiologist and cycle coach… email in profile should you want some professional assistance.

To correlate speed with power (outside, not on a turbo), WEIGHT, rolling resistance, and aerodynamic drag DO matter – as do the physiological mechanisms that provide the power output. (and a host of other bits and pieces that have a small effect also).

OP – get someone with a powermeter to ride on your turbo to check the calculations.

160W for 20mph…I’d have thought more

On a ‘flat’ ‘smooth’ road – 20 mph costs me ~250W and I am ~78 kg.

edit: that is on a Cervelo aero road bike, Zipp 303 aero rims, and with Conti’s race tubular tyres.

Being fit AND/OR fast is about how you train, not whether you want to race, or not. But, effective training is (generally) based upon science.

To make any sense of the ‘254 watts’ part you first need to know what the ‘pre ride proper’ was all about – given the value of ~250W is *might* have been some type of really simple ‘threshold’ type test – but as you were wearing jeans and chatting – it likely wasn’t performed with any precision (or the required effort). It might just be that the average power during your ride was 254W.

I am just taking my powermeter out for a spin – but if you want to email me we could talk about POWER some more – I do this stuff for a living.

Great stuff – I won’t likely be able to respond till the evening as I have a client In my lab in the morning (over from Nice – small world) and then we are off out for a training ride and (coffee and cake meeting) in the afternoon – its a rock’n’roll life! But, I will get back to you – promise!

…cool! I see you live in the alps – don’t let the distance thing concern you – I currently work with athletes who live in Finland, Israel and France (along with the UK) – there are ways and means!

HungryMonkey – I am an exercise physiologist and I do a fair amount of consultancy and applied sports science ‘stuff’ with a range of athletes – including ultra-endurance and stage racers. If you want some assistance with your training and preparation drop me an email.

I have the kit to do metabolic tests to prescribe individualised training zones and to identify a multitude of thresholds and VO2max etc. Drop me an email if interested.

The only problem when you have a name like:

DE WERT Chris

As you get three columns and it separates the surname.

But, I can manually edit these – not a big deal.

Rondo101 – awesome – thanks!

Everyone – I have learnt lots today, thank you all for your time and patience – it is really appreciated!

I guess I will be a little more cheeky, whilst I have so many excel GODS on here – If I have a name in a cell such as this:

SMITH John

Is it possible to remove the ‘John’ and leave the ‘SMITH’ with a formula of some sort?

Njee20 – you are indeed correct – that didn’t work when I tried it first time, but did the second – maybe I highlighted the column, not the cells, or something?

Anyway, hyperlinks sorted now – thanks!

Rondo thats right – but the:

rondo101
portlyone
LabMonkey
reggiegasket

Is what I see in the cell already – the hyperlinks are hidden

But deleting the original and rewriting the same text makes it work.

Does anyone now how to the the macro thing on a Mac?

A few things to try – this will take me a little while to work through – thanks everyone!

When I hover over the name (in the cell) I get a ‘finger’ symbol and a hyperlink to the webpage appears but in the bar the name is shown.

Deleting the name (with hyperlink) and retyping the name again solves the problem – I just have 550 names to delete and retype (without any spelling mistakes of course).

Njee20 – that is exactly what I have.

Would it matter if the short list of names is copied and pasted from an internet page and so if you click on them they contain hyperlinks?

It appears that it does matter – as when I delete the original name and retype it myself it works.

So next and likely final question – can we remover the hyperlinks without having to delete and retype all the names?

Njee50 – I just get a long list of #N/A’s?

Scratch that – it works on a small sample list I just made up – but not on my big list – I am probably just doing something silly.

Is it really that easy? OMG! Runs off to try – thanks!

Edit: what happens if the names are not in the same row? Will it still work ok?

Stoner – you made me smile! cheers.

If you reduce blood supply to the brain it could be fatal – but ‘something else’ would make you stop exercise well before the brain has to intervene – for example a reduction in intramuscular phosphocreatine, the accumulation of metabolites (H+, ADP, Pi, H2PO4 etc) or an intolerable change in acid-base status.

Oh god… what are we starting here?!

I am not really ‘here’ – I am busy ‘working’ on something else – I am just flicking back – and, it is a bit too late for a central governor debate.

But if we are brief, ischemia, in what context?

I take it as meaning a restriction in blood flow, in the context of exercise?

Haha – don’t get me started on the central governor!

iDave is correct – you don’t *feel* the lactate – you feel the hydrogen ions (H+) that are released when lactic acid is dissociated. i.e., the H+ causes a change in intracellular pH – and you feel this change in acid-base status – if – bicarbonate doesn’t mop up the free H+.

Ton – I don’t know if you saw my earlier post? But I might be able to help you out a little, email in profile if interested. Cheers, Jon

Hi Ton – I am an exercise physiologist and I have experience of helping cardiac rehab patients return (safely) to exercise. I might be able to help you – drop me an email if you are interested.
Cheers, Jon
Ps. iDave speaks sense – I can’t help you over the Internet, but I do have laboratories for safe physiological/exercise capacity testing.

OP – I can help with your question but I am
just leaving for a ride – drop me an email and I will explain all later.

Yeah – 26lbs? – I have a full XTR tracer (36’s, CK hubs, 819 rims – RQ tyre on front, race king on rear) and that is pushing 30lbs – the covert frame is not half the weight of a racer frame.

Overtraining can be a problem for all – IF – you increase your training stress too quickly – AND – don’t factor in adequate recovery.

ps. I am an exercise physiologist and I can help with training etc – email in profile.

phil.w – Member

do you have one LabMonkey?

Yes, well, I don’t own one myself as they cost ~£300K – but there is one just downstairs from my office.

Fact of the day – LabMonkey has 24% head fat.
