Too much jogging is ‘unhealthy’

first_img Tweet National guidelines suggest exercising for 150 minutes a weekToo much jogging may be as bad for you as not putting on your running shoes at all, a report in the Journal of the American College of Cardiology says.Scientists studied more than 1,000 healthy joggers and non-joggers over a 12-year period.Those who jogged at a steady pace for less than two and a half hours a week were least likely to die in this time.But those who ran more than four hours a week or did no exercise had the highest death rates.‘Upper limit’Analysing questionnaires filled out by all the people in the Danish study, scientists concluded the ideal pace was about 5mph (8km/h) and that it was best to jog no more than three times a week or for 2.5 hours in total.People who jogged more intensively – particularly those who jogged more than three times a week or at a pace of more than 7mph – were as likely to die as those who did no exercise.Researcher Jacob Louis Marott, from the Frederiksberg Hospital in Copenhagen, said: “You don’t actually have to do that much to have a good impact on your health.“And perhaps you shouldn’t actually do too much.“No exercise recommendations across the globe mention an upper limit for safe exercise, but perhaps there is one.”Scientists are not yet sure what is behind this trend – but they say changes to the heart during extreme exercise could contribute.‘Brisk walking’In their report, they suggest: “Long-term strenuous endurance exercise may induce pathological structural remodelling of the heart and arteries.”Maureen Talbot, senior cardiac nurse at the British Heart Foundation, said: “This study shows that you don’t have to run marathons to keep your heart healthy.“Light and moderate jogging was found to be more beneficial than being inactive or undertaking strenuous jogging, possibly adding years to your life.“National guidelines recommend we do 150 minutes of moderate-intensity activity a week.“It may sound like a lot, but even brisk walking is good exercise. And if you’re bit of a couch potato, this is a good place to start.” 199 Views   no discussions Share Sharing is caring!center_img Share Share HealthLifestyle Too much jogging is ‘unhealthy’ by: BBC News – February 3, 2015last_img read more

Dein lauds Wenger

first_img Dein helped to bring Wenger to north London in 1996 and, almost two decades later, Arsenal have firmly established themselves as one of the most envied clubs in the world. Wenger is the man who can take most responsibility for that according to Dein, who thinks he will be an “impossible act” to follow when he finally leaves the club. “He’s won three Premier League titles and two doubles in that of course,” he said. “Four FA Cups, he is the longest-serving manager in the Premier League today and he has, if I’m not mistaken been manager of the month 13 times which is in itself more than anyone else other than Sir Alex Ferguson, so he leaves behind a phenomenal legacy of what he has achieved on the pitch but also off the pitch. Wenger is yet to agree a new contract – his current deal expires in the summer – to create some uncertainty over his future. Dein is certain, however, that he has the passion to stay on, adding: “He still has the fire in his belly and wants to win every game. “We have a ritual that after a home game we go up the road and we normally have dinner together with his wife and my wife – but only if we haven’t lost. If we’ve lost he’s bad company. It’s a monologue instead of a dialogue. “The other day I said to him you’ve probably had 1,000 games with other clubs and 1,000 with Arsenal, you’ve probably had collectively about 2,000 games. “I asked what does that mean to you? He looked at me and said: ‘Two thousand sleepless nights’. “That tells you a lot about the man.” Former Arsenal vice chairman David Dein has hailed Arsene Wenger for “transforming” the club as the French boss prepares for his 1,000th game in charge of the Gunners this weekend. “He has transformed the club, revolutionised the club,” Dein said in an interview on Sky Sports 1. “Whenever he decides to leave he will be leaving behind a phenomenal state-of-the-art training facility, a wonderful stadium, a very good squad which he is trying to improve and a legacy of what he’s won. “Arsene is a football purist. He has a lovely phrase, he calls it ‘possession with progression’. “Arsene Wenger transformed the club on the pitch and off the pitch. I will go on record as saying he won’t be a difficult act to follow, in my opinion it will be an impossible act.” Wenger will reach the 1,000-game landmark against Chelsea at the weekend and – following Sir Alex Ferguson’s exit from Manchester United last summer – Dein does not expect another manger to come close to matching his record. “I would go on record and say I don’t think we will see that again in our lifetime,” he said. “It’s a phenomenal milestone; 1,000 games at one club for 18 years. In modern football the longevity in the whole of the 92 professional clubs, you know how long a manager stays in his job for? Eleven months, and Arsene has been there for 1,000 games which is absolutely astonishing.” Despite not winning a trophy for eight years Dein believes Wenger’s record at Arsenal stands the test of time.

Duminy, Elgar centuries power Proteas to 388-run lead

first_img(REUTERS)-South Africa’s JP Duminy and Dean Elgar both scored centuries in a third-wicket partnership of 250 to drive the tourists to a 388-run lead over Australia at the end of the third day of the first Test yesterday.Australia removed both centurions around the tea break, as well as Temba Bavuma and captain Faf du Plessis in the last hour, but by then the damage had been done and the Proteas will go into day four on 390 for six.Quinton de Kock, who was dropped by Adam Voges on one, was at the crease unbeaten on 16 at the end of a long, hot day at the WACA, along with Vernon Philander, who had made 23 not out.South African paceman Dale Steyn was ruled out of the rest of the series with a fractured shoulder on Friday and will play no further part in the match, reducing the number of wickets Australia need to take.Steyn was a member of the Proteas team that chased down 414 to beat Australia at the WACA in 2008 but it was a debutant Duminy who scored the three runs off Mitchell Johnson that got the South Africans over the line.Now 32, Duminy looks to have played a key role in another Perth triumph after his brilliant 141 rammed home South Africa’s advantage after they had skittled Australia for 244 in reply to their 242 on Friday.Duminy faced 225 balls and hit 20 of them for fours with another going for six, overhauling partner Elgar before lunch and reaching his fifth test century with two runs to deep cover soon after the break.NERVOUS NINETIESIt was his first century in two years and his third against Australia, just reward for a masterclass of calm control and shot-making.The end came just as it looked like the pair of left-handers would bat through to tea, Peter Siddle benefiting from a DRS review when the technology revealed a nick off the bat that carried through to wicketkeeper Peter Nevill.Elgar did not have such a good experience on his previous visit to the WACA, having got a pair when he made his test debut at the ground in 2012, albeit on the winning team.Dogged and determined where Duminy was fluent, the 29-year-old reached his fifth test century half an hour before tea after a prolonged spell in the “nervous nineties”.His career-best 127 came off 316 balls and he had hit 17 fours and one six when Josh Hazlewood finally winkled him out after tea when he offered a tired shot and got an edge which Mitchell Starc took at gully.Starc should have caught Elgar on 81 when the batsman skied the ball to mid-off but he lost the ball in the Perth sun, tripped himself over trying to readjust his position and spilled it on the turf, to the despair of bowler Nathan Lyon.The left-arm paceman also accounted for Du Plessis (32), a fine edge taken behind by Nevill, while Hazlewood had Bavuma well caught by Usman Khawaja at deep square leg for eight but the collapse Australia needed never materialised.After Perth, the series continues in Hobart before concluding with a day-night Test at Adelaide Oval.SOUTH AFRICA 1st innings 242 (Q. de Kock 84, T.
