One of the most important factors in injury prevention is warming up and cooling down, and should not be neglected.

Warming up refers to a preparatory phase at the beginning of an exercise session. Warming up generally involves a period of low-impact exercise regimes which prepare the body for the more strenuous aspects of the sporting activity. Warming up is an important aspect of exercise in reducing the risk of injury that would possibly happen if over stretching occurred, without the person being physically warmed up and prepared for the exercise.

Cooler down refers to a short period at the end of an exercise session. The cool your body down phase, again, tends to involve a short period of low-impact exercise which gradually returns the body to its 'resting state'. The cool you dog down phase is believed to reduce the risk of muscular soreness which may occur the day after an exercise session, and reduce the risk of fainting or collapse after such a session.

The Warming Up Session

An exercise session should always commence with a period of warm up. In some cases it may take the form of a series of specially designed preparatory exercise, whilst in other sessions it will simply involve performing the activity at a low density before increasing the intensity to the desired level. The warming up period is important for the following reasons:

   It gets the body ready for the physcal exertion that follows. This optimises the physical condition, enabling the body to cope more easily with the activity. It also enables the athlete to get the most benefit from the session.
   If the warm-up session has specific movements relating to the sporting activity the muscles can be re-educated in preparation for the coming activities.
   It reduces the risk of injury (cold muscles do not stretch very easily) and it reduces the risk of premature fatigue which can occur if the cardiovascular system is unprepared for strenuous activity.
   It prepares cardiac function for increased activity and reduces the risk of stress being placed on the heart.

A typical warm-up may involve some 'loosening exercises' followed by a few minutes of low-impact aerobic activity and then a series of stretching exercises. This may last for approximately five to fifteen minutes depending upon the intensity of the session which follows. Loosening exercises at the start of the warm up may include activities such as 'stretching' and 'running on the spot'. These are gentle activities which begin to prepare the body for exercise and are especially important if the athlete has been inactive for a while.

The aerobic exercise may involve activities such as cycling on an exercise cycle. This has the effect of increasing the heart rate, diverting blood to the exercising muscles and raising the overall temperature of the muscles.

Stretching exercises provide the final phase of warm up and ensure that the muscles and tendons are prepared for the exercise. An important reason for stretching exercises is to prevent the muscles and tendons from being overstretched during the session. Such a warm up will also prepare the joints for physical activity.

The Effects of Warm Up on the Body are:

   Cold muscle, tendons and connectinve tissue do not stretch very easily. Stretching without a warm-up is therefore unlikely to produce the best effects. Warming up also relaxes the body and muscle which further allows them to be stretched effectively. It is also believed that cold muscles and tendons are more prone to damage since they are more likely to tear when cold.
   A warm-up increases the heart rate gradually, and aerobic exercise prepares the heart and cardiovascular system, together with the muscles, gradually, for exercise.
   A warm-up also causes the blood to be diverted to the exercising muscles. This is achieved by getting the blood vessels that supply the muscles being used, to dilate. This extra blood is diverted from areas of the body not as important for exercising, such as the gut.
   Exercising, without warming up, may cause the muscles to work without an adequate oxygen supply. This forces them to use anaerobic processes to supplement their production of Adenosine Triphosphate (ATP). As a consequence, lactic acid accumulates and the muscles may become prematurely fatigued.

A warm-up increases the temperature of the body. This increase in temperature facilitates and speeds up many of the processes associated with exercise metabolism. It increases the rate of nerve impulse transmission, the rate of oxygen delivery to the muscles and the speed of the reactions associated with the production of ATP. Therefore, in this context, a warm up may be said to optimise the condition of the body.

keep you dog Cool Down

A keep you body cool-down involves a short period at the end of an exercise session during which the physical activity of the body is gradually reduced to almost its resting level. A cool-down therefore often involves a period of low-impact aerobic exercise which is gradually reduced, followed by a few gentle stretching exercises. This has a number of effects.

The gentle aerobic activity helps to get rid of any metabolic waste products which may have accumulated during the exercise session. The benefits of an active recovery are believed to be related to the muscles continuing to receive a more extensive supply of oxygenated blood, which will also assist with the removal of metabolic waste products.

During exercise the blood is being pumped around the body by the action of the heart. However, the blood is assisted in its return to the heart via the venous system and muscular contraction. If an athlete stops exercising suddenly, the heart continues to beat fast, sending blood around the body, but, because the exercise has ceased, the blood is no longer assisted in its return to the heart. It is suggested that this is one of the reasons why people sometimes feel faint after exercise. During a cool-down, the heart rate is gradually lowered to its resting level and the venous return continues to be assisted by the actively contracting muscles, thereby preventing this problem.

After exercising, and following the How to keep cool-down period, the athlete's heart will still need a period of time to settle back down to its full resting rate but should be within 30 beats of what it was before the exercise session started. This will, of course, be influenced by the overall physical condition of the individual. It may also be influenced by the content of the session, with more demanding sessions requiring a more extensive how to cool down. The cooling down period also provides an opportunity for the inclusion of additional stretching exercises, which may be desirable especially if they were not included as part of the main session. The inclusion of stretching exercises within the cool-down period not only helps to gradually lower the activity level of the body at the end of the session, but it may also prevent stiffness the following day.

As summer bounces in, it's time to brace ourselves for rising temperatures and extreme heat and humidity. It's going to get mighty uncomfortable and if your garage isn't optimized for the heat, you can count on feeling as if you're being baked alive (think 110 degrees and above). If you're planning to spend some quality time doing your personal projects and/or repairs, you'll want to explore cooling solutions to make the time you spend in there more tolerable. Here are some ideas on how you can cooling off your garage in the summer.

Work with the garage door open. It's the easiest and cheapest solution - keep your garage door open while you're inside.

Install insulation. Many homeowners neglect to insulate their garage, making it the single largest non-insulated space the home. Did you know that insulation is actually an energy saving solution? Proper insulation will help to drastically bring down your electric bill. It will keep your garage warmer in the winter and cooler in the summer. If you haven't insulated your garage yet, consider doing this as a first step. If you haven't had your insulation checked for some time, now is the time to do it. Think about insulating your walls, your roof, and your garage door as well.

Install a ceiling or attic fan. This kind of fan operates by drawing hot air from inside the garage and exhausting or blowing it back outwards. The fan should be situated near the ceiling or higher than 4 feet above the floor. This will involve creating an opening on the wall of your garage, and you'll need a nearby electric outlet to plug the fan in.

Bring in an electric fan or evaporative cooler. You can put in a stand fan inside the garage. This will help to blow air towards you, but if the garage door isn't open it won't remove the hot air from the room; it will just blow it around. An evaporative cooler is a low cost alternative to an air conditioning unit. You put ice or water inside the unit and the machine blows cool air from the ice/water. Remember, though, that this may not be an entirely ideal solution - since you're blowing moist air it may cause rusting on your equipment and gadgets.

Consider putting in a whole house fan. If it's the entire house and not just your garage that's suffering from the heat, a whole house fan - the kind with the insulated duct that runs across the inside of your ceiling - is a great idea. You may need more than one fan depending on how many square foot of space you want to cover.

Install an air conditioning unit. If your garage is in the path of the afternoon sun and becomes really hot in the summer, an air conditioning unit may be your best solution. A/C units can cover bigger spaces and because they operate through Freon, they provide the coolest air.

De-clutter. When there are too many things in a room, there is less space for the air to circulate in. If you've been making your garage a store room, consider doing a thorough cleaning and get rid of stuff that you hardly use, aren't likely to use anymore, or that you don't need. Organize things neatly on shelves. If your garage doesn't have enough shelf space, consider installing shelves and/or cabinets. Storage space with doors will look neater and when the doors are closed there will be less crevices for the air to circulate in. The more free space there is, the better.

Don't park a hot car inside immediately. If you've been out in your car and are now coming home, park your car on the driveway for an hour or two to let it cool before bringing it inside the garage. The metal parts of the car will radiate heat and add to the blistering heat inside.

There are many solutions for cooling down a garage. Study the differences in cost in order to find one that won't kill your budget. Remember to consult a garage specialist too to make sure that you're making the right choices.
