Because golf is a leisurely sport, many people don’t think of it as promoting heart health. Conversely, since it is easygoing, injuries are believed to be rare. The August issue of the Harvard Men’s Health Watch debunks these myths and advises readers how to benefit the most from their golf game.
Golf can be good for your health and safe for your heart. These health benefits don’t come from swinging your club, but from walking. Walking an average course for a round of golf can be as much as four miles. If you walk 18 holes three to five times a week, you’ll get an optimal amount of endurance exercise for your heart. If you pull your clubs or carry them, you’ll burn more calories per round, and benefit even more.
The August issue of Harvard Men’s Health Watch warns golfers of the likelihood of injuries, which is greatest in older players and infrequent players. Because a golf swing involves the whole body, any part of the body can be injured in the course of play. Common injuries include shoulder problems like rotator cuff tendonitis, hand and wrist injuries like carpal tunnel syndrome, “trigger finger,” as well as elbow inflammation. Back muscle strains are also common and some players can experience serious back injuries. Golfers can also develop strains, sprains, and tendonitis of the knees, ankles and feet.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
