The "core" is a common term used to refer to the middle section of the body between the lower part of the rib cage and the hips. There are 29 muscles in this area including the pelvis, spine, lower back, hips and trunk. Core muscles maintain body stability and transfer power from the legs to the upper body and vice-versa. Core strength training improves overall body functional power, balance, posture and may help reduce the risk of injury. By understanding and applying the science related to the core muscle stability and strength, you can develop more effective running mechanics and avoid lower back pain and other physical challenges. Why your Core Muscles are Important Your core muscles are essential to your overall physical fitness because your body is an interconnected system. For example, tightness in your hamstrings can cause pain in your lower back and a ft injury can lead to pain in your hip. The core muscles help stabilize the entire body and transfer force from the lower body to the upper body. They are also a part of the "kinetic chain," which is a sequence of events that allows each part of the body to be activated at the optimal time and sequence to execute a given movement. A gd example of the kinetic chain is how a soccer player uses their whole body in sequence to kick a soccer ball. In running, the example would be how the left arm moves in sequence and time with the right leg to transfer forces, stay balanced and to run effectively and efficiently. To ensure the optimal functioning of all parts of your body, you need to make sure that your core is strong, stable and flexible. Research has discovered significant links between core strength and speed in distance runners. Subjects who completed a six-week core strength training program of back extensions, hip raises, Russian twists and abdominal crunches on a stability ball experienced a statistically significant improvement in their 5km run times versus a control group that did not engage in core strengthening.(1) This study also found that lower leg stability and running kinetics remained unchanged for all of the runners involved, illustrating the importance of training the core in combination with the lower body to promote overall running performance. Another study illustrated the interconnected nature of the body by illustrating that tennis players who had a proper knee bend and body position were less likely to sustain an elbow or shoulder injury.(2) Improve Your Performance When developing your core muscles, you need to focus on both muscle strength and muscle endurance. This is because these core stability muscles are used in most daily activities, not just while running. If your core muscles are not well developed, they will become easily fatigued and you will be at greater risk of instability, injury, and pr running mechanics. When you are designing a program to build your core, make sure it includes exercises that build both the strength (fewer reps and more resistance) and endurance (more reps and less resistance) of your core muscles. Always start with less resistance and progress slowly to higher resistance levels. You also need to keep in mind that because the whole body is connected, you need to activate your core in a way that also engages the nearby lower and upper body muscles so that the whole system learns to work together. Sample activities that will create this dynamic are hip raises while you lie on your back, superman raises (alternate legs and arms being lifted while you lie on your stomach), and side and front planks. For runners, these exercises are great because they relieve stress on the hamstrings, lower back and knees while still strengthening the core muscles. They will also simultaneously develop the strength and flexibility that is needed in the core muscles because keeping the core strong but fluid and open is important for energy transfer. Make sure you have a fitness professional show you how to do these exercises properly to maximize the training effect and minimize your risk of injury. Because core training puts stress on the spine, it is critical that you learn how to do the exercises properly. You should always focus on balance and control while training the core muscles and make sure a professional (certified physical trainer, kinesiologist, or your athletic/physio therapist) teaches you proper technique before you practice on your own. In particular, if you have a history of back pain, make sure you consult a physiotherapist of chiropractor before beginning a core strengthening program to make sure there are no underlying causes of your back pain or weakness. For an excellent core strength program that is specifically designed for people who are rehabilitating from back injuries, go lk into Solid to the Core at www.solidtothecore.ca. Developing strength in the core of the body is critical for most sporting movements, especially running. To get the benefits, core stability and strengthening exercises must be performed regularly and consistently – just like you need to run regularly and consistently. To establish a fluid and strong set of core muscles, follow these tips: • Do core exercises at least three times a week• Focus on exercises that engage your core muscles but also work the surrounding upper body and lower body muscles• Build up slowly if you are just beginning to exercise your core muscles• Be aware of your spine alignment at all times and ensure that you are engaging your core muscles and maintain gd posture (avoid sagging or slumping).

After Gasquet beat fifth-seeded Ivan Dodig of Croatia 7-5, 6-3, Tsonga followed up with a 6-7 (3), 6-2, 6-2 win against sixth-seeded Edouard Roger-Vasselin in an all-French match. No team has been more dominant at the Olympics over the past 20 years then the U.S. womens basketball team, winning five straight gold medals.Theyll try and keep that streak going in Rio.Training time is always our biggest challenge, said three-time gold medalist Sue Bird. When you get to the medal rounds its one and done, but we have a lot of experience in those games and lk to continue our recent success.The Americans have won 41 consecutive Olympic contests dating back to the bronze medal game in 1992, winning by an average of nearly 30 points a game. With nine players, including Bird, Diana Taurasi and Tamika Catchings, returning from the London Games, the U.S. is a heavy favorite to win another gold medal.Olympic newcomers Elena Delle Donne, Brittney Griner and Breanna Stewart will add a dynamic mix to the veteran core.The only potential thorn for the U.S. is lack of training time. While most other countries get to spend months together preparing, the U.S. has about two weeks before its first game. Although a lot of that time has been spent crisscrossing the country.Im hoping that they remember some of the stuff that we did last year at the World Championship and a couple years ago at the Olympics and maybe February at that little training camp that we had, U.S. coach Geno Auriemma said. Fortunately, theyre a lot of the same players that played. So we havent changed a whole lot. But theres not much time and theres not much that you can do to get ready. You just have to trust that theyre ... They never let you down. They always seem to respond when you need them to.The U.S. is in a difficult group with Serbia, China, Canada, Spain and Senegal.Obviously were in a tough group, Auriemma added. Because anytime you have the European champions like Serbia already in the group and Canada, the Americas champion, those are two really gd teams. And then you add in China and Spain.Here are a few other things to watch for in womens basketball at the Olympics:A LITTLE REVENGEThe U.S. is also out for a little bit of revengge.ddddddddddddThe last time they played in Brazil at the 2006 World Championship, they lost to Russia in the semifinals. It was their only defeat in either the Olympics or worlds since 1992.I hadnt thought about that until you brought it up, Bird said laughing. The fans down there definitely know their basketball and like rting against us. As the deficit against Russia grew, the cheers started getting louder for them.MEDAL CONTENDERSWhile the gold medal is most likely a foregone conclusion, the other two spots on the podium are up for grabs. France was the silver medalists in 2012 and Australia has won either a silver or bronze at every Olympics since 1996. Other candidates for a medal could be Serbia, which won the European championship, and Canada.SCHEDULE CHANGEThis year there will be a change in the competition structure. With the men and women playing in different arenas until the quarterfinal rounds, teams can play on consecutive days. The U.S. doesnt begin play until Sunday, Aug. 7 against Senegal. The Americans then play the next day against Spain. There will only be three or four games per day now instead of the six there used to be. Its the first time this format is being used since the 1984 Olympic in Los Angeles.GOLDEN GIRLSIf the U.S. does win another gold, Taurasi, Bird and Catchings will join Teresa Edwards and Lisa Leslie as the only basketball players to win four gold medals.SLAM DUNKAustralia center Liz Cambage became the first woman to dunk in the Olympics in London. Will the 6-ft-8 star have an encore in Brazil? Keep an eye on Brittney Griner, the odds are the 6-8 American will add her name to the list.IMPRESSIVE STREAKSOnly two other traditional team sports have longer consecutive gold medal streaks than the U.S. womens team. The American mens basketball team won seven consecutive golds from 1936-68. The India mens field hockey team won six in a row from 1928-56. ' ' '
