Beetroot juice gives stamina a boost

The University of Exeter led-study has for the first time shown how the nitrate contained in beetroot juice leads to a reduction in oxygen uptake, making exercise less tiring.

The study reveals that drinking beetroot juice reduces oxygen uptake to an extent that cannot be achieved by any other known means, including training.

To reach the conclusion, research team conducted their study with eight men aged between 19 and 38. They were given 500ml per day of organic beetroot juice for six consecutive days before completing a series of tests, involving cycling on an exercise bike. On another occasion, they were given a placebo of blackcurrant cordial for six consecutive days before completing the same cycling tests.

After drinking beetroot juice the group was able to cycle for an average of 11.25 minutes, which is 92 seconds longer than when they were given the placebo. The group that had consumed the beetroot juice also had lower resting blood pressure.

Workplace yoga could beat stress
Is your expanding waistline due to desk job giving you nightmares? Well, then try workplace meditation and yoga, suggests a pilot study.

According to the study, 20 minutes per day of guided workplace meditation and yoga combined with six weekly group sessions can lower feelings of stress by more than 10 per cent and improve sleep quality in sedentary office employees.

The study offered participants a modified version of what is known as mindfulness-based stress reduction (MBSR), a programme established in 1979 to help hospital patients in Massachusetts assist in their own healing that is now in wide use around the world.

Fractures raise mortality rates
Hip and back fractures increase mortality rates in older adults, says a McMaster University study.

The research has found that approximately 25 per cent of men and women who develop hip fractures and 16 per cent of people who develop spine factures will die over a five-year period.

The study was led by George Ioannidis, Michael G DeGroote School of Medicine, in collaboration with scientists from the schools of medicine and nursing at McMaster, as well as several universities across Canada.

Using data from the Canadian Multicentre Osteoporosis Study, the researchers examined the relationship between new fractures and mortality over a five-year period in more than 7,750 Canadians aged 50 years and older.

Insufficient sleep ups diabetes risk
Short sleep times may contribute to the development of insulin resistance and reduced glucose tolerance, which in turn may elevate the risk of diabetes, concludes a new study.

The study will be published in ‘The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism’ (JCEM).

Sleep curtailment is characterised by physical inactivity and overeating.

The new study examined whether reduced sleep duration itself may increase the risk of developing diabetes when combined with physical inactivity and overeating.
