A new study testing the benefits of a virtual exercise partner shows the presence of a moderately more capable cycling partner can significantly boost the motivation

Attitude may play an important role in how exercise affects menopausal women, according to Penn State researchers, who identified two types of women — one experiences more hot flashes after physical activity, while the other experiences fewer.
‘The most consistent factor that seemed to differentiate the two groups was perceived control over hot flashes,’ said Steriani Elavsky, assistant professor of kinesiology. ‘These women have ways of dealing with (hot flashes) and they believe they can control or cope with them in an effective way on a daily basis.’
Women who experienced fewer hot flashes the day after participating in vigorous to moderate physical activity were more likely to be part of the group that felt they had control over their hot flashes. Women who had more hot flashes following exercise were likely to be those who felt they had very few ways of coping with their hot flashes, Elavsky and her colleagues report in a recent issue of Maturitas.
Elavsky suggested that cognitive behavioural therapy may help some women feel they have more control over their bodies and reactions to hot flashes.
The participants with fewer hot flashes the day after vigorous exercising were also less likely to experience anxiety and depression. However, women who had fewer hot flashes the day after only light or moderate physical activity had higher levels of pessimism and depression than others.
‘The bottom line for research is that people need to look at individual differences,’ said Elavsky. ‘It’s not enough anymore to do a study and look at overall impact of an exercise program on symptoms. It’s very clear that we need to look at the different responses that women might have, and try to understand these individual differences more.’
Elavsky and her colleagues followed 24 menopausal women for the length of one menstrual cycle, or for 30 days if they were no longer menstruating. Each woman used a personal digital assistant to record hot flashes and wore an accelerometer at the hip to track physical activity. The women in the study regularly had hot flashes before the start of the study, experiencing from five to 20 a day.
‘The real-time reporting of symptoms and the objective measurement is a strength of the study,’ said Elavsky. ‘There aren’t any studies out there that use both of these approaches.

A recent report in The Lancet has concluded that blood pressure should be measured in both arms as the difference between left and right could indicate underlying health problems such as vascular disease.

Dr Christopher Clark and colleagues, from the Peninsula College of Medicine and Dentistry at the University of Exeter, reviewed 28 previous study papers on this subject.

According to the study, the difference between arms is important, although the arm with the higher pressure can vary between individuals. Most people in the study had an elevated blood pressure risk and about one-third had a normal level of risk.

The study concluded that a difference in systolic blood pressure of 10 millimetres of mercury (mm Hg) between arms could identify patients at high risk of asymptomatic peripheral vascular disease. A difference of 15 mm Hg would also indicate an increased risk of cerebrovascular disease, a 70% increased risk of cardiovascular mortality and 60% increased risk of death from all causes, the authors said.

Peripheral vascular disease (PVD) is the narrowing and hardening of the arteries that supply blood to the legs and feet. There are often no symptoms. Early detection of PVD is important because these patients could then benefit from stopping smoking, lowering their blood pressure or being offered statin therapy.

Writing in The Lancet, Prof Richard J McManus, department of primary care health sciences at the University of Oxford and Prof Jonathan Mant, from the department of public health and primary care at the University of Cambridge, said the review supports existing guidelines.

Prof Bryan Williams, from the Blood Pressure Association and the University of Leicester, said the study reinforced the message already in the guidelines from health watchdog NICE.
