You exercise so intensely that your muscles burn and you gasp for breath. Then you slow down for a minute or two, catch your breath, and then go very fast again. This training technique has been used in all endurance sports since the 1920’s. Now George Brooks of the University of California at Berkeley has shown why interval training makes you a better athlete (American Journal of Physiology-Endocrinology and Metabolism, June 2006).

Inside each muscle cell are mitochondria, the little furnaces that burn fuel for energy. A major fuel for your muscles during exercise is the sugar, glucose. In a series of chemical reactions, glucose is broken down step by step, with each step releasing energy. When enough oxygen is available, the glucose releases all of its energy until only carbon dioxide and water remain; these are blown off through your lungs. However, if not enough oxygen is available, the chemical reactions stop at lactic acid which accumulates in the muscles and spills over into the bloodstream. Lactic acid makes muscles acidic and causes a burning feeling. This recent research shows that lactic acid is the most efficient source of energy for muscles. Anything that helps muscles to break down lactic acid faster will make you a better athlete because it will increase your endurance and allow you to move faster when you are tired.

Since lactic acid is burned for energy in the mitochondria, anything that enlarges the mitochondria builds a bigger furnace and helps to increase endurance. Lactic acid is carried from the cells into the mitochondria by special proteins called lactate transporter molecules, so anything that increases these molecules will build endurance. An enzyme called lactic acid dehydrogenase is needed to start the reaction, so anything that increases this enzyme will also help. Interval training does all three: it enlarges the furnace (mitochondria), increases lactic acid transporter molecules, and increases the amount of lactic acid dehydrogenase.

Treadmill running differs from road running in a number of ways and this should be considered when training. The first obvious difference is the lack of wind resistance when running indoors. Another difference is the surface. Although experts differ on this issue a smooth moving surface underneath your feet is not the same as an uneven stationary road. Most runners agree that running on a treadmill feels different to road. This should be taken into consideration when training. Is running on a treadmill better than the road? This comes down to preference. Many prefer being outdoors whereas others have environmental, climatic or personal safety concerns making treadmill running an ideal choice.

Firstly let’s look at the psychological factors of running on a treadmill compared to the road. Unless you have a large room for your machine you will most likely to be facing a wall or window within a few meters. Research has shown that runners on treadmills take shorter paces that may be due to the proximity of a barrier or fear of falling off. It does take time to learn how to run on a moving surface and even when confident many runners will tighten their lower backs, again possibly a psychological reaction to staying on the machine.

When comparing physical technique, research has found that when the foot lands on the belt the foot, ankle and shin, become temporarily part of the belt and move backwards from the centre and mass of the body at the same speed. This means the shinbone of the leg landing is not as upright as with normal running and has a greater range of motion. Treadmill running can be useful for injured athletes, using a mirror can be a good way to observe your technique (although it must be recognised that it is not the same as training on the road).

Whether using a treadmill or road you will need to vary your running program for two reasons. Firstly, if you continue doing the same distance and the same speed you will get less and less benefit as your body adapts. Secondly, you can soon become de-motivated by the same thing week in, week out. Alternating between shorter faster runs and longer distances at a slower pace will help to condition your body and improve endurance, muscle strength and cardio-vascular function. It will also provide you with variety and a different challenge for each session.

I usually recommend runners to use one or the other exclusively, because I see them as different activities.

Running is one of the best ways to get into shape and to stay in great condition, because it is a sport you can practice on your own time, at your own pace, and without a lot of fancy equipment. However, making running your primary mode of exercise can prove to be a bit problematic because it puts your fitness at the mercy of the elements. Running on a crisp fall afternoon is a lot different than trying to hit the sidewalks for a great run in the heat of a scorching August day or in the frigid chill of a snowy January. Luckily, dedicated runners have developed ways to keep improving their skill and strength even when Mother Nature is not on their side.

During the warm days of summer, the most important thing that you as a runner need to worry about is dehydration. The combination of sweating from exertion and from the heat can take its toll. Many runners who are not anticipating the effects of the weather on their hydration levels end up facing symptoms that range from temporary discomfort to very serious problems that can land even the fittest runner in the hospital. To protect yourself from this summertime menace, be sure to drink plenty of fluids throughout the day. It is crucial to carry a bottle of water or a sports drink on your run with you. But because the stomach can only absorb a limited amount of fluid at a time, it is equally important to keep feeding your body liquid throughout the day in order to gradually replenish the water that you will inevitably lose on your run.

When the weather outside is chilly, runners often have trouble keeping their muscles warm enough, which can lead to injury. Cold increases stiffness, which makes muscles less flexible and responsive, and therefore more vulnerable to trauma. If you are set on running outdoors during the winter, you should plan on investing in some new running gear that will help you protect yourself against the dangers of cold weather. Shoes with enough traction to handle slippery patches of ice, and a good pair of athletic pants that will wick away your sweat while keeping your legs warm, are two crucial parts of safe winter running.

Many runners are firm believers that the great outdoors is the best place to run, and the benefits of sunshine and fresh air are certainly important. However, when the climate is inhospitable for running because of snow, excessive heat, slippery wet ground, or any number of other factors, it is often a better idea to hit the gym rather than the streets.

Running on a treadmill can help you build up your strength and endurance without risking the kind of injuries that hazardous weather can bring. Running on a treadmill is gentler on your knees than running on pavement. Because of this, many fitness experts recommend alternating between outdoor and treadmill running regardless of the weather. By knowing when it is a smart idea to stay inside, you will be able to make sure you avoid weather-related injuries so that you can be in peak condition when you get your next chance to run outdoors.
