				|  October was the American 
				Physical Therapy  Association’s National Physical Therapy Month and this year the feature was biking 
				for fitness while minimizing injury.  
				 |

				| What are the Benefits of Biking? | 
			
			
				| Biking is an excellent non-impact aerobic 
						exercise program. You can bike indoors on an exercise bike or enjoy the fresh 
						air on a street bike. We have also seen the level of competition that biking 
						can offer with events like the Tour de France. We teach young children to begin 
						riding bikes at a young age to help them develop their balance and 
						coordination. A bike is an outstanding mode of exercise for rehabilitation of 
						ankle sprains, knee injuries, joint replacement surgeries, etc. Best of all, in 
						general, there are no age boundaries for biking. But, as always, if you have 
						any medical conditions, you should first consult your health care provider 
						before engaging in strenuous physical exercise.

				 | 
			
			
				| How Should the Bike Fit?
							
				 | 
			
			
				|  Whether you ride for recreation or 
						competition or for your own wellness or aerobic conditioning, a proper fit on a 
						regular or an exercise bike is of utmost importance to ensure comfort and 
						prevent injury or unnecessary pain. Below are a few tips for ensuring a 
						good comfortable fit and minimizing the possibility for excess strain or 
						injury. 
				 | 
			
			
				 | 
			
			
				| Seat/Saddle 
				 | 
			
			
				| You need to be sure that the seat/saddle 
						is a good fit for your hips/buttocks. The seat should not be too narrow. A 
						narrow seat/saddle can give you pressure areas in the groin and the tail bone 
						area (coccyx). The seat/saddle should not be too wide because it will not only 
						give you pressure areas along the bottom of the buttocks (ischial 
						tuberocities), but an extra wide seat can actually restrict your hip range of 
						motion necessary for pedaling the bike. 
				 | 
			
			
				 | 
			
			
				| Bike Frame | 
			
			
				| An exercise bike’s frame size is not as 
						critical as the frame of a regular bike. When it comes to the street and/or 
						racing bicycles, the rider and the bike should fit well together. To measure 
						the correct frame for your body size, carefully review the manufacturer’s 
						recommendations and seek assistance from the bike shop sales associates. There 
						are a couple of simple ways that you can test for yourself if the bike fits you 
						well. Here a few recommendations:
				 | 
			
			
				|   | 
			
			
				
							
								- 
								Begin by getting up on the bike while your toes still touch the ground while 
								you are on the seat. To prevent excess strain on the neck, lower back and 
								shoulders, check the handlebars position. The higher the handlebars, the more 
								weight will be placed on the seat/saddle. Generally, taller riders should have 
								lower handlebars in relation to the height of the saddle.
								
 - 
									Next, check the pedal length. When in the full down 
        stroke, the knee should be slightly bent, not fully stretched or 
        straight leg that you have to hike your other hip to get the pedal all 
        the way around. This is because if the leg is fully stretched, it would 
        not only reduce the efficiency of the pedaling force, but could also 
        produce excessive stress on the knee and the hip 
          joints.

				|   | 
			
			
				| In addition to above sizing 
						considerations, one must not forget how important it is to do proper 
						stretching, balance, and flexibility exercises. Make sure to do calf stretches, 
						hamstring stretches, neck mobility, shoulder stretches, and shoulder rolls to 
						name a few. For balance, you could work on unsupported squats and walking on 
						toes and heels. These are just a few suggestions. Check out, “Stretch into 
						Shape -- 5 exercises to keep you flexible and prevent injuries,” at 
							http://www.prevention.com/article/0,5778,s1-2-69-210-4179-1,00.html a 
						few stretching exercises.

				 | 
			
			
				| Your choice of footwear for bicycling is 
						also important: A soft-soled shoe is best for comfort and flexibility, as the 
						soft-soled shoe will grab the pedal better than a hard-soled shoe. If you want 
						the special bike shoes with clips, you should speak with professional bike 
						sales personnel. 
				 | 
			
			
				 | 
			
			
				| With these preparation suggestions in 
						mind, let’s get out and bike for fitness before old man winter arrives! 
						Remember to exercise regularly for fitness and let fitness be a way of your 
						life.
