It is a mistake to believe that playing a sport will keep you fit! Much depends on the level of fitness you wish to achieve.Playing a sport will, of course, benefit you over doing no exercise at all, but it is an undisputed fact that if you only participate in a sport say once or twice a week, then this is not going to make you fit. In fact, if you play a particularly demanding sport, such as squash or rugby etc. then you must definitely do some physical training to keep in the best of fitness. As you get older, it can be very stressing on the body to play squash.It is for this reason that most people who take part in sport, to a reasonable standard, also take there training seriously. The training must also be of a specific kind to meet the particular sport in question.It is of no use doing long marathon type of training if you are a 100 yard sprinter, the requirements are completely different. We have sports that are of an anaerobic nature, other that are aerobic and yet others that are somewhere between aerobic and anaerobic.However, it is very important to get expert advice on the correct way to train for your particular sport. As a tennis coach, we like other sports have a periodisation plan, i.e. covering long term goals and short term goals and taking into consideration the necessity to peak at the correct competition times. In broad terms, we do our strength and endurance training to start with; then introduce speed and specific movement training, combining the two 50/50 and finally very specific tennis training.This shows the importance of getting some good advice, taking into consideration what you want to achieve, but be careful in thinking that by doing the same exercise week in and week out, that your body will be receiving it’s best results. You could be wrong.
