New Delhi, Jan 1: Six months of yoga lifestyle "significantly reduces" blood pressure in pre-hypertensive patients, a new study by doctors at a city hospital has claimed.

The study, recently published in the Journal of Hypertension, was conducted by researchers from the Department of Neurophysiology of the Sir Ganga Ram Hospital (SGRH).

"It was a randomised study of 120 patients to study the effect of yoga lifestyle on ambulatory blood pressure in patients with high normal blood pressure (prehypertension)," the hospital said in a statement.

The patients were divided into two groups -- Group A (yoga), who were assigned to practice yoga an intensive lifestyle modification; while patients in the Group B (conventional) were prescribed the conventional lifestyle modifications (exercise, diet, smoking cessation), it said.

"Twenty-four hour diastolic BP particularly the night diastolic and mean arterial pressures showed a significant decrease from the baseline in the yoga group compared to the conventional group, whose members underwent lifestyle modifications at 12 weeks," said Nandini Agarwal, author of the study.

"This study has convincingly demonstrated that yoga intervention in patients with prehypertension can significantly reduce blood pressure," Agarwal claimed.

M Gourie Devi, Chairperson, Department of Neurophysiology at the SGRH, said, "Hypertension is a major public health problem throughout the world with over one in five adults affected worldwide and this is likely to increase to 29.2 per cent by 2025."

Pre-hypertension is a precursor of clinical hypertension and is closely related with the increased incidence of cardiovascular and cerebrovascular diseases, Devi said.

Sandeep Joshi, co-author of the study, said, "Patients with prehypertension (120- 139 / 80-89 mmHg) have an increased risk of cardiovascular morbidity and mortality compared with patients who have normal blood pressure (less than 120/80 mmHg)."

The yogic practices that were followed in the study were, health rejuvenating exercises, asanas, breathing and relaxation exercises and meditation, the hospital said.

Chennai, Apr 23: Shane Watson brought back memories of last year's IPL final with a blazing knock that has now almost ensured a play-off berth for Chennai Super Kings as they beat Sunrisers Hyderabad by six wickets here Tuesday.

On a vastly improved Chepauk track, Watson roared back to form with an 96 off 53 balls as CSK stuttered a bit in end before winning in 19.5 overs.

Watson's innings studded with nine fours and half a dozen of sixes ensured that CSK have reached the cut-off limit of 16 points needed for the play-off even though they would like to finish in the top two.

Watson's innings would also be a relief for skipper Mahendra Singh Dhoni, who had urged the top order to finish matches.

A 77-run stand between Watson and Suresh Raina (38) created the platform and the former Australia all-rounder singlehandedly decimated the Sunrisers attack.

What made it more difficult for the Sunrisers was the fact that their strike bowler Rashid Khan was pulverised by Watson, who took him to the cleaners with 44 coming off his spell.

Sandeep Sharma was another bowler, who was handed severe punishment as he went for 54 in 3.5 overs. Sandeep repeatedly bowled short and Watson would gleefully pull him. Skipper Bhuvneshwar Kumar (1/18 in 4 overs) had no option but to bowl the 19th over and left Sandeep with nine runs to defend.

However Kedar Jadhav literally finished the match with a six off the second ball that sealed the deal.

Earlier, the immensely talented Manish Pandey was back in his element as his unbeaten 83 off 49 balls powered Sunrisers Hyderabad to a fighting 175 for 3 after being put into bat.

Pandey and league's current leading run-scorer David Warner (57 off 45 balls) added 115 runs for the second wicket to lay the foundation for a decent score on what was the best batting track on offer at the Chepauk.

Veteran spinner Harbhajan Singh struck an early blow, having the in-form Jony Bairstow caught behind in the second over for a duck.

He was the most successful bowler with figures of 2 for 39 in four overs while Deepak Chahar picked up the wicket of Vijay Shankar (26 off 20 balls).

Despite the early dismissal of Bairstow, the visiting team didn't get tied down as the irrepressible Warner and Manish Pandey kept hitting those boundaries and sixes. They brought up the team's 50 in the sixth over.

Pandey who has not been in the best form, hit his straps, scoring freely and was not afraid to go over the top. Dhoni's shuffling of the bowlers didn't make much of an impact as Warner and Pandey kept attacking.

Pandey was the first to reach 50 in 25 balls, pulling one from Dwayne Bravo for a boundary.

Warner was a touch slower in comparison to Pandey, but didn't miss out when the opportunity presented itself and hit a couple of big sixes.

The pugnacious Warner fell against the run of play, victim of Dhoni's trademark lightning quick stumping off a Harbhajan delivery. The Australian, who is leading the run charts this season, fell for 57 (45 balls, 3x4, 2X6) after adding 115 runs for the second wicket with Pandey.
