Worried about whether being physically active just on weekends can make a difference in health if the rest of the week is spent sitting all day? Well, there is good news! Being a "weekend warrior" (one who exercises or is active only one or two days a week) may also offer health benefits according to a new study (associated with lower death rates from all causes, cancer, and cardiovascular disease).

Current government guidelines recommend at least 150 minutes per week of moderate-intensity activity (such as brisk walking or tennis), or at least 75 minutes per week of vigorous activity (such as jogging or swimming laps), or equivalent combinations of moderate and vigorous physical activity. From Science Daily:

'Weekend warriors' have lower risk of death from cancer, cardiovascular disease

Physical activity patterns characterized by just one or two sessions a week may be enough to reduce deaths in men and women from all causes, cardiovascular disease (CVD) and cancer, regardless of adherence to physical activity guidelines, a new study of over 63,000 adults reports. The finding suggests that less frequent bouts of activity, which might fit more easily into a busy lifestyle, offer significant health benefits, even in the obese and those with medical risk factors.

Regular physical activity is associated with lower risks of death from all causes, cardiovascular disease and cancer, and has long been recommended to control weight, cholesterol, and blood pressure. The World Health Organization recommends that adults do at least 150 minutes per week of moderate-intensity activity, or at least 75 minutes per week of vigorous-intensity activity, or equivalent combinations.

But research is yet to establish how the frequency and total weekly dose of activity might best be combined to achieve health benefits. For example, individuals could meet current guidelines by doing 30 minutes of moderate-intensity physical activity five days of the week or 75 minutes of vigorous-intensity physical activity on just one day of the week. Those who do all their exercise on one or two days of the week are known as 'weekend warriors'.

The great effects (especially for hemorrhagic stroke) were found in people eating just 1 1/2 portions of fresh fruit daily. The amazing part is that 6.3% admitted to never consuming fruit. From Science Daily:

Fruit consumption cuts cardiovascular disease risk by up to 40 percent

Daily fruit consumption cuts the risk of cardiovascular disease (CVD) by up to 40 percent, according to research. The findings from the seven-year follow-up study of nearly a half million people in the China Kadoorie Biobank found that the more fruit people ate, the more their risk of CVD declined.

Dr Du said: "CVD, including ischaemic heart disease (IHD) and stroke, is the leading cause of death worldwide. Improving diet and lifestyle is critical for CVD risk reduction in the general population but the large majority of this evidence has come from western countries and hardly any from China."

The current study included 451 681 participants with no history of CVD and not on anti-hypertensive treatment at baseline from the China Kadoorie Biobank(1) conducted in 10 different areas of China, 5 rural and 5 urban. Habitual consumption of fruit was recorded at baseline according to five categories: never, monthly, 1-3 days per week, 4-6 days per week, daily.

Over the seven year follow up period there were 19 300 cases of IHD and 19 689 strokes (14 688 ischaemic and 3562 haemorrhagic). Some 18% of participants consumed fruit daily and 6.3% never consumed fruit. The average amount of fruit eaten by the daily consumers was 1.5 portions (~150g).

The researchers found that compared to people who never ate fruit, those who ate fruit daily cut their CVD risks by 25-40% (around 15% for IHD, around 25% for ischaemic stroke and 40% for haemorrhagic stroke). There was a dose response relationship between the frequency of fruit consumption and the risk of CVD.

Dr Du said: "Our data clearly shows that eating fresh fruit can reduce the risk of cardiovascular disease, including ischaemic heart disease and stroke (particularly haemorrhagic stroke). And not only that, the more fruit you eat the more your CVD risk goes down. It does suggest that eating more fruit is beneficial compared to less or no fruit."

The researchers also found that people who consumed fruit more often had significantly lower blood pressure (BP). Eating fruit daily was associated with 3.4/4.1 mmHg lower systolic/diastolic BP compared to those who never ate fruit. 

In a separate analysis, the researchers examined the association of fruit consumption with total mortality and CV mortality in more than 61,000 patients from the China Kadoorie Biobank who had CVD or hypertension at baseline. They found that compared to those who never ate fruit, daily consumers of fruit cut their overall risk of death by 32%. They also reduced their risks of dying from IHD by 27% and from stroke by around 40%.
