Water and Hydration

WATER
Water constitutes about 75% of our muscle tissue, 22% of bones, 74% of your brain, 25% of fatty tissue and works within every single cell in the body to transport nutrients and remove waste products. It regulates body temperature allowing heat to evaporate from the skin in the form of sweat. Put simply, the body breaks down without adequate fluid! When we are dehydrated, blood becomes thicker so the body must work harder to transport it to the brain so we lose concentration and feel fatigued.
It is also important to note that too much water is detrimental to performance. The latest research from the American College of Sports Medicine and USA Track & Field says that thirst is an appropriate guide as to when fluid replacement should be commenced. This means drink when you feel your body needs it and stop when you feel satisfied. From this point on in your session consume water regularly.
Bottled water has nudged past milk to become the second most-consumed commercial drink in the country. Due to this there are purified, fortified, enhanced, flavoured waters and more and so it’s worth considering which type is best. I would say simple bottled is best wherever possible and this is due to the endless amounts of research detailing contaminants in tap water and realistically it varies region to region so much that I couldn’t hazard a guess at the quality we drink daily.
Hydration after Exercise
· Weigh yourself before and after training.
· Drink 500-600ml water for every 1 lb lost. You can include your water used for mixing the recovery drinks and protein.

Is Coffee Bad?

Caffeine use in elite sport is a well researched area and so I can evaluate many studies and detail some evidence based tips for you on its use to maximise performance. Firstly, the increase in nerve activity brought about by consuming caffeine stimulates the release of the hormone epinephrine (adrenaline) which in turn, leads to such effects as increased blood flow to muscles and the release of glucose by the liver. Caffeine also increases brain levels of the neurotransmitter dopamine, which is involved in cognitive (thinking) processes, alertness and memory. For this reason alone there are numerous studies which show that caffeine significantly improves mental focus. Also in a recent study from the University of Scranton, Pennsylvania, researchers showed that coffee is the number one source of antioxidants in the average American's diet.
If stimulatory effects are your goal then freshly brewed black coffee is the way to go and not a large latte which is full of milk! An average cup of black freshly brewed coffee contains about 130 milligrams of caffeine (compare that to the 80 milligrams in a regular Red Bull), plenty to give you the mental focus you are after. But remember, everything in moderation because athletes who rely on caffeine to get "up" for games or training are often creating a mental "barrier" that is hard to escape. And as your body develops a tolerance to caffeine it will take more and more caffeine to get the same feeling of "focus" you've come to expect. Also avoid putting a lot of sugar or sweeteners in your coffee or you will ruin the effect you are looking for by increasing sugar content just like r
egular Red Bull. So if you want to use coffee as a pre training/match stimulant then you must not over use it during the week! A maximum of one cup per day would be advised and then 1-2 cup freshly brewed coffee 1-1.5 hrs before competition (game time).
Will it dehydrate me?
A study on the effects of high dose pre-exercise caffeine ingestion found no significant impact on hydration (Can J Physiol Pharmacol, 68(7): 889-92, 1990). Other studies have showed a mild diuretic effect in extremely high doses (8 cups filter coffee per day!). However, this diuretic effect is also governed by the concentration of caffeine in any given drink. For example, an espresso coffee provides around 100mg of caffeine in just 50ml of water, but you’d have to drink around 1 litre of tea to obtain the same amount of caffeine, significantly hydrating your body in the process! A medium Americano contains around 100mg caffeine (1 espresso shot) but 350 ml water.
My advice is clear on caffeine, if you want to gain a stimulatory benefit from it then abstain from using it a lot until competition/training time. The message from years gone by of cutting out tea and coffee is WRONG because there is no evidence of a diuretic effect when used this way and you will also then lose the hydrating effect of drinking the water you made it with!

The Turkish Get-up
It was used by strongmen back in the iron days and for very good reason. For PT's in posh gyms maybe this will make gather a few strange glances from moustached businessmen or over tanned woman but so whgat, its a great exercise for strength, power and endurance development.
So how do you do it?
1.Lie on your back with your KB or Db in your hand, elbow locked.
2.The idea is that you stand up without flexing the elbow and keeping the weight directly above you
3.Firstly, flex the trunk and get one hand down as a stable base
4.Get onto one knee and keep weight above you with elbow locked
5.with the other leg now behind you ina semi split squat position, stand upright
6.Now return to starting position by simply reversing these steps
Here is a perfect example of the turkish get-up:

Tips:
Keep your eyes on the weight at all times
Start out with a light weight until you get a feel for the movement

Accurately predicting injury in collision sports
Collision sports such as rugby league and rugby union have a high incidence of injury due to the impact on their bodies during both training and competition. Much research has centered on how we can prevent injury and following on from this we have seen many papers on prehabilitation and exercises to address muscular imbalance and poor inefficient movement mechanics.
