Yeah it's a load of rubbish. Playing a few extra games in the League Cup and FA Cup, albeit against weak opponents, hasn't impacted their form at all. And Guardiola went with a strong lineup in each of those games as well. It hasnt impacted Spurs' league form either and they have a paper thin squad. Neither of them look dead on their feet.
You don't tend to see it show up in form and performances until April. This is when our warm weather training will really start to reap dividends and City's players will be tired and red lining. Until then, we wait.
That's just complete speculation, or wishful thinking.
"During periods where the schedule is particularly congested (i.e. two matches per week over several weeks), the recovery time between two successive matches can be between 2 and 4 days, which may be insufficient to restore normal homeostasis."
http://www.aspetar.com/journal/viewarticle.aspx?id=180#.XG6VY6L7SigToo many games absolutely does have an effect, and it's likely to be a worse effect the longer it goes on for, and it's very clear that the kind of schedule City in particular are facing falls into that critical '2-4 days' recovery time phase, a schedule that will be (assuming they stay in the CL) pretty relentless for them until the end of the season.
Shall we google some stuff about warm weather training and see what comes up? I don't know much about it, so we can find out more together...
https://ridefullgas.com/news-archive/5-benefits-of-warm-weather-training-in-winter/"As the ex-head of British Cycling, Peter Keen, once said: “The bottom line is that the body does not get fitter through exercise. It gets fitter through recovery”.
https://www.sportscoverdirect.com/scd-blog/2015/10/30/warm-weather-training-benefits/"During the winter we often see media reports about people suffering from a lack of vitamin D, especially amongst those that do not get enough sunlight, which is a natural source. Research has suggested not only that a lack of vitamin D can lead to sporting injuries but that the vitamin can actually improve muscle strength, speed, stamina and reaction time.
It is often said that a change is as good as a break and many of the benefits of warm weather training are psychological. I have already mentioned how it is easier to be motivated when the sun is shining but there are other benefits. Training away from the normal routine and away from work and other responsibilities can give athletes the space to refocus on their goals and objectives. Often athletes suffer from a mid-winter lull but exploring new training rides and meeting new people can give an athlete a much needed boost."
So, as well as the bit about recovery times (the bits which directly contradict your post about lots of games having no effect), we're talking about thinks like extra vitamin D, lower risk of injury and psychological benefits - less stress, change of environment etc etc.
Do these all sound like things that you're going to see immediately? Like 1 extra match in the weak = shit performance in next match? Or do they sound like things that are felt more over time, with increased injuries, players losing motivation, players being unable to recover from niggly injuries etc etc?
And if they're things that you're likely to see over time, do you think that you're more likely to see the benefit during a short term spell of 'form' or over a longer term, like, say, looking back at the end of the season?
