While a lot of middle-aged adults have begun exercising, after realising its potential health benefits, new research claims that even the fittest among them are not immune to cardiovascular disease (CVD)– and they often do not have any symptoms.

The study, from the University of British Columbia (UBC) in Canada, highlights how important it is for middle-aged adults to have their doctor check their CVD risk factors, especially if they have high blood pressure, high cholesterol or a family history of CVD.


CVD refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke.

“We all know that exercise is good for us–it can help prevent a range of health problems and diseases, from cancer to depression,” said lead author Barbara Morrison, doctoral student at the UBC.

“However, even if you are really active, our findings suggest that you still can’t outrun your risk factors,” she added.

For the study, published in the journal BMJ Open Sport and Exercise Medicine, the team followed 798 “masters athletes” — adults aged 35 and older who engage in moderate to vigorous physical activity — running to cycling, rowing and hockey — at least three days a week.

Of the 798 athletes, 94 (11 per cent) were found to have significant CVD. Ten participants were found to have severe coronary artery disease — a blockage in their artery of 70 per cent or greater — despite not having any symptoms.

While the results may seem alarming, Morrison emphasised that it does not mean middle-aged adults should stop exercising.

Moreover, it is also important to practice moderation when it comes to exercise, Morrison noted.

“There is no evidence that pushing exercise to the limit will make you live longer or your heart stronger, but when taken to the extreme, it may have the potential to do harm,” said Morrison. (IANS)

Tokyo Olympics 2020 Indian wrestler Ravi Kumar enter semi finals.

Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.

On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.

Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.

Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).

Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.

India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.

He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.

Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.

The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.

Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
