Powering through in 2010 with my powerlifting

I have just come to the end of my first training cycle of 2010. It has been a good start to the year. I have been following a Westside Barbell split, which I had good gains with a few years ago when I started powerlifting. On reflection, it has been good to come back to it and has definitely helped in two of my lifts (Squat and Bench) and not so good in the other (Dead Lift).

I am very pleased with my lifts, as only in November I was lifting significantly less, although I have put on weight and a fair amount of body fat since then. I am now weighing about 90-91kg, instead of the lean 81kg back in November at the Worlds. My lifts have definitely benefitted from this weight increase and now it is time to get my muscles a lot stronger and not just rely on the increase in body weight.

I am now taking a week off and looking to go into a new training cycle for the second quarter of 2010. Having gone to watch the British Championships this weekend, I can see I have a lot of work to do to catch up to the other 90kg lifters in that category, Andy Bonner and Henry Tosh both lifting 660kg + totals. It is great to have these goals though and I totally believe I can be among them, maybe not next year or the year after, but in a few years.

I have not decided on what program or split I am going to do yet and will keep you updated on the program choice. I am a believer in modeling oneself on people who have been successful, this doesn't just apply to my powerlifting, I apply this to my life in general. So, I am looking into programs such as Jim Wendler's 5 3 1 program, Ed Coans routines, maybe a different Westside Barbell Split, I am not sure yet. As I said though, I will keep you posted.

The role of fluid in and around exercise sessions

Water makes up around 45% - 70% of our total body weight (2). Organs, all tissue and all bodily fluid contain water contain water as a essential constituent. Very little water is stored in the bones, teeth and hair (3).

Under normal conditions, such as a temperate climate, fluid balance is regulated by thirst sensations and by regulation of loss by the kidneys. Loss of water through urination, sweat, respiration and feces determines the amount of water required by the body. The total water intake for young men and women (ages 19 - 30) is 3.7L and 2.7L/day, respectively (6).

The risk of dehydration can be a real factor during exercise, which, unless sweat losses are replaced, the temperature of the body will go up, which can lead to heat exhaustion, heat stroke and even death. We can track sweat loss through changes in our weight. A total body weight loss of 1% can have and elevate our core temperature. A 3% - 5% loss of fluid in body weight can affect our cardiovascular system and impair our ability to dissipate heat. A 7% loss of fluid in body weight can result in collapse (2).

We can monitor our fluid loss during exercise by weighing ourselves before and after exercise. Remove sweaty clothes for accuracy. Every .45 kg or 1 lb, lost during exercise is the equivalent of 1 pint (2). This must be replaced before the next workout. Other indicators of dehydration can be dark yellow, strong smelling urine, a decreased frequency of urination, a rapid resting heart rate and muscle soreness last many days (1).

Fluid Replacement

Replacing fluid occurs at three general times. We want to start exercising in a hydrated state to we consume fluid before we start and to avoid dehydration, continue during exercise and replace fluid loss after the exercise session has finished.

Before Exercise

You want to consume 1 pint (500 ml) of fluid 2 hours before the exercise session starts. This allows us to be hydrated and allows for urination before the exercise session starts (2). The fluid can come in any form, water, juice, milk etc and can be consumed with a meal.

During Exercise

When consuming fluid during exercise, the aim is to get fluid into circulation to match the speed that the body is getting rid of fluid through sweat. This can be achieved by taking in fluids that are fast absorbing e.g. water. The drink also wants to be palatable. Fluid should be consumed before feeling thirsty. If the stomach can take it, it is better to take in large amounts of water, rather than sip, as large volumes empty from the stomach quicker than small volumes (2).

A variety of fluids can be consumed during exercise (4). Cool water is the ideal, although if water is unpalatable, then adding flavoring to it can be done, which means you can drink more (2). Aside from fluid intake, there has been no evidence to support that there is a physiological benefit of drinking a carbohydrate drink during exercise, if the exercise is less than 1 hour long.

Water should be consumed frequently, with around 200 ml - 250 ml consumed every 15 minutes of exercise (2).

After Exercise

The goal after the training session is to get the body ready for the next workout. As mentioned above, weighing yourself before and after can allow you to monitor fluid loss and indicate how much fluid to take in after the exercise session has finished.

If large amounts of fluid has been lost through sweating, sodium chloride (salt) levels may be low and so drinking fluid or eating food containing sodium chloride, minimizes urine output and speeds up recovery of water and electrolyte balance (5).

Most fluid intake occurs when consuming food, with water coming from both food and beverages. Drink plenty of water during the day aiming for 3 - 4 L a day and adding an extra 1 L - 1.5 L to account for fluid loss on days that you are exercising.
