Sit less, move more!

Physical activity (PA) helps prevent or treat increased blood pressure, coronary heart disease, stroke, diabetes, breast cancer, colon cancer and depression. It improves memory and mental health. It is recommended to undertake 150 minutes of moderately intense exercise each week.  2 strength training sessions should also be undertaken as well as working on flexibility and balance. Research into the amount of physical activity people undertook used to be difficult, the production of accelerometers (now widely available as “watches”) has allowed researchers to accurately quantify how much physical activity individuals undertake. It has been shown that there are low levels of…

PHYSICAL ACTIVITY REDUCES SPORTS INJURIES

Physical activity is important in the prevention and treatment of many significant medical conditions including heart and lung disease, diabetes, cancer, increased blood pressure, obesity, osteoporosis and depression. One of the few drawbacks of physical activity is the possibility of injury.The chance of injury is dictated by factors related to the individual – Intrinsic –  (body make up/fitness/ability/gender/risks they take/age) and those acting on them externally – Extrinsic – the activity they participate in (rugby/ snooker/ gym) and the environment in which they play (extremes of temperature/altitude, quality of playing surface).

At least 35

This is the answer to the question of how many hip replacements a surgeon should undertake a year. Each year approximately a million hip replacements are performed each year. Outcomes are generally excellent with over 95% of hips surviving for at least 10 years. Unfortunately complications do occur including infection, bone fracture, loosening, death and dislocation. Complications can be affected by patient, implant and surgeon factors. The operation is technically demanding and takes a long time to learn to perform correctly. A recent study has shown that the risk of dislocation increase in surgeons undertaking less than 35 hip replacements…

Marathon Running

When training for a marathon, everyone will have different aims and objectives, but hope to arrive at the start line in the best physical and psychological condition possible. I have treated a large number of people who have “broken down”, often very close to a race. There are some basic principles that are worth thinking about. Equipment Most training shoes require replacement after approximately 500 miles. Wear one pair in whilst one is wearing out. Have your running/foot pattern properly assessed so that you buy a pair that is suitable for you. Many shops will “advise” you, but a proper running shop is recommended. Video gait…
