Sharla's Log

Sharla, if you can get hold of Biochemistry of Exercise vol V11 volume 21 you will enjoy, bicarbinated Soda stops the warning system through acid breakdown from working as it should and can overstrain the Heart its a NO NO.

Thanks Scrap and Salty,

Great input as always.

I found the bicarb soda info in a Women's Health mag so women everywhere in Australia are likely to be trying it - a bit scary to hear it's dangerous!

I'm actually really suprised the acidity of gastric juices in the gut doesn't nuetralize the bicarb before it reaches the bloodstream but I guess it is absorbed too quickly for that.

I was thinking that the cycling part makes sense. My mum's running improved when she began cycling and that is a common scenario I've heard in triathlon circles. Further capillarization occurs to allow a cyclist to operate at their maximum heart stroke volume. Maybe that serves to help running performance even though it's not induced by running?

There wouldn't really be any equivalent exercise for your arms though would there not without extreme discomfort from all your blood rushing to your head! Pity it would be great for boxing conditioning!

Anyway I had thought that especially for women who are unlikely to increase heart stroke volume any other way maybe endurance training would be an advantage even for boxing. Perhaps endurance swimming or a low impact endurance sport at least.

Reading about the conversion of fast twitch to slow twitch muscle fibres and knowing the capacity of heart stroke volume increase is fairly small I'm not so sure now. Damn!

In general i think it might say something positive about increasing capillarization in the legs by cycling.

I think that must be how trained cyclists overcome the heart stroke volume limitation seen in non-cyclists are tested on stationary bikes.

My mum's running performance increased when she started cycling and that's quite common from what i've heard. I'd say it would be a good initial improvement but I'm not sure if you'd continue to improve for long.

Apparently guys have slightly bigger hearts than women (along with more hemoglobin, lower body fat percentages, more muscle etc etc ) so you'll have a larger stroke volume than me. Pity it's so hard to target in training for an athlete trying to maintain fast twitch muscle fibres.

Thanks for the article Salty - i will definately study it

I'll look for that text you mentioned too Scrap - sounds like something that should be available at uni - good to know there are some perks for being a uni student!

One thing I would mention about training your lactate threshold is that it does not discriminate where you do it. For instance if you just train your right arm the left will exhibit similar gains, so running will improve that of the whole body, but if I were you I would find a cross trainer to do it with high resistance. Cross county skiing can be one of the best workouts your can ever do, too bad we don't have snow over here in Aus though

Thanks Salty

I look forward to the guide!

I'm going to look up more on muscle fibres - I just don't really want to believe that they can only be converted from fast to slow and won't go back!

Especially in response to an Adult's training rather than during a young person's development? It sounds more like deterioration than an adaption to exercise.

Perhaps that's what it is though - less ability to react to firing neurons as quickly since they are not maintained or something? I'll have to read up on it!

[Sharla]

Right I'm still reading it but I found an article RE fast and slow twitch muscles fibres that might be of interest:

About.com: http://www.the-aps.org/publications/classics/articles/ingalls.pdf

And another one:

It is generally accepted that muscle fiber types can be broken down into two main types: slow twitch (Type I) muscle fibers and fast twitch (Type II) muscle fibers. Fast twitch fibers can be further categorized into Type IIa and Type IIb fibers.

Bsically i think from these articles the evidence is inconclusive although granted I might want to keep looking for more up to date info.

I'm wondering how much mentality comes into it also.

I feel most confident with a strong endurance base and I think longer workouts tend to be a good outlet. I generally only need one real endurance and perhaps one semi-endurance workout per week to see improvement. I don't see it including these sessions as being at the cost of other workouts neccessarily since I doubt I'd make gains from having more than 2 max 3 speed sessions a week?

[Scrap]

Sorry missed this on the other post, Fibres can be altered over time. Also 3 maximum sessions a week is enougth for fitness. The secret of fitness is recovery Time, and having a good Vo2 max base. Boxing Fitness is in the catogary of middle distance Running train accordingly, its a mixture

[Sharla]

Thanks Scrap

So by middle distance you might mean say a 10 km runner?

I'll look into that.

I've been reading articles on the Ross Boxing site and one relating to patience hit a nerve.

I guess that's what part of this is about - having the patience to trust that a few quality workouts a week is better than a heap of shitty ones, not to mention the patience to stick with a training program for a decent amount of time rather than changing it more often than your underwear.
