1 . Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.

A study followed more than 80,000 people for an average of nine years to find out if certain sports protected them against early death. It found that people who played racket sports regularly were the least likely to die over the study period, reducing their individual risk by 47 percent compared with people who did no exercise. Swimmers also reduced their chance of death by 28 percent, aerobics (有氧运动) fans by 27 percent and cyclists by 15 percent. Yet running appeared to have no impact at all on dying early, and neither did playing football or rugby.

Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash (壁球), which often involve clubs and organized activities outside of the game. It means that people often have larger social net-works and tend to keep up activities into later life, both of which are proven to be good for health.

In contrast, people who play team sports often do not move onto a new sport once their teams break up for family, or injury reasons. They become watchers rather than participants in their chosen activity.

The researchers found that playing racket sports was associated with a 56 percent lower risk from heart death. Similarly, swimmers lowered their heart disease or stroke risk by 41 percent, and people who took part in activities like aerobics, dance or gymnastics lowered their risk by 36 percent. But again running, football and rugby had no significant impact on heart deaths.

However, other experts argue that this study must not be misinterpreted as showing that running and football do not protect against heart disease. In this study both runners and footballers had a lower rate of death from heart disease.

2 . Try This at Home!

Are you looking for a new pastime that will create a balance between physical activity and relaxation? Then yoga may be the perfect choice for you. Yoga can be practiced by people of all ages and levels of fitness.    1     It's a great way to strengthen your muscles and become more flexible.

In the 1930s, Indian Sri Tirumali and K. Pattabhi developed one of the most popular forms of yoga practised worldwide today. They worked together using an ancient Sansknt text called Yoga Korunta to create a set routine of yoga movements and breathing exercises.     2    

Ashtanga is different from other forms of yoga. It is a very powerful form of aerobic (有氧的)exercise which creates deep heat in the body.     3     In other forms of yoga, however, the routine can change each time and the stretching exercises aren't aerobic.

By focusing on your breathing while doing physical exercise, you are able to get a balance between mind and body.
