How is our lifestyle influenced by our spouse’s lifestyle changes? Effects of smoking and alcohol consumption have been examined in this regard but few studies have assessed this relationship when it comes to physical activity. A recent study in The American Journal of Epidemiology has done just that.
The study included more than 3,000 married couples aged 45-64 years. Participants were examined twice, at baseline and after 6 years. Physical activity was assessed using questions about the frequency, duration and intensity of sports/exercise and leisure activities.
The biological level ageing results from the impact of the accumulation of a wide variety of molecular and cellular damage over time. But these changes are neither linear nor consistent, and they are only loosely associated with a person’s age in years. There is no ‘typical’ older person and some 80 year-olds have physical and mental capacities similar to many 20 year-olds.
However, as we grow older our bodies are changing. We may grow a little rounder around the waistline, or wake in the night, or feel a little stiffer in the morning. Most of us have to start to use glasses, and slowly our hear turns grey. Some even loose it. As we grow older increased forgetfulness that not is impairing our daily life is considered to be a part of the normal aging process. Generally, information processing also slows as we grow older, and older people have more trouble multitasking. However, research find that problems with memory, language, thinking and judgment that are greater than normal age-related changes, also called cognitive impairment may increase the risk of later progressing to dementia. Still, some people with mild cognitive impairment never get worse, and a few eventually get better.
There are several large ongoing project in CERG and OptimEx is one of them. OptimEx is a large multicentre project financed by the European Union and researchers, engineers and technicians from several countries and institutions are involved. I am working with OptimEx as a PhD student and therefore I will give the readers of our blog a short version of what OptimEx is all about and why it is invested so much in the project.
As we already know, lifestyle diseases are a huge and increasing burden on the healthcare system. One of the lifestyle diseases that are continuing to grow is heart failure with preserved ejection fraction named HFpEF. HFpEF is one of two types of heart failure affecting more than 7 million Europeans and accounting for 50% of all heart failure cases.
Agathe – Ageing At Home, is a Grundtvig Learning Partnership under the European Commission’s program for Lifelong Learning, and last month they came to visit us at CERG, and learn more about our project on exercise on elderly, Generation 100.
– We are five partners from Germany, Poland, Spain and Norway who visit each other and learn about how each country try to make it possible for elderly people to live longer at home. Our project aims at building in each country support structures for elder people’s self-determined living at home in structurally weak rural regions, i.e. to create good conditions in order to enable people to live longer at home, project leader Øivind Solheim explains.
The response to exercise training is often described in general terms, with the assumption that the group average represents a typical response for most individuals. However, in reality, it is more common for individuals to show a wide range of responses to identical exercise programs. In 1999, a large study published by Claude Bouchard and colleagues, reported that 20 % of us show little or no gain in maximal oxygen consumption (VO2max) with exercise training. This is a concern, since a high VO2max is associated with decreased rates of cardiovascular morbidity and mortality. Exploring the phenomenon of high responders and low responders following the same exercise program may provide helpful insights into mechanisms of training adaptation and methods of training prescription.
Exercise is healthy, and most of us do not get enough compared to what is ideal for good health. Debates and research focus has understandably gone in depth to look at effects in both sick and inactive. There has also been an important focus to find the most effective and time-saving workouts that can make it easier to motivate yourself to get a good effect. Meanwhile there is a growing group of people who have had the opposite challenge to contend with; exercise addiction. A Danish documentary was recently broadcasted on Norwegian television, showing this growing problem and how exercise totally governed their life.
Would you take your bike or your feet to work on this road? This picture is from the beautiful bike and walkway in Brisbane, Australia. Spending time here made us very happy. On the pathway numerous walkers and runners passed us, and a great deal of people bike to work. The beautiful pathways along the Brisbane river is a part of the CitySmart project. The aim of the project was to turn Brisbane into the most sustainable city in Austrailia, and last year they made it!
To make it easy and beautiful to use active transportation not only saves energy, but gives a lot of people better health and quality of life. Earlier this month we attended the first workshop aiming to make our own city, Trondheim a Smart City. Visiting Brisbane has given us a lot of inspiration and ideas to bringe home.
Cross fit is a workout method using a combination og endurance and strength exercise training, implementing the interval exercise principle quite a bit during training. During the Bondi Fitness Festival Professor Ulrik Wisløff presented the results from the maximal oxygen uptake testing at Bondi Corssfit, together with a presentation of our main reserach focus and results, in addition to a demonstration of high intensity interval training performed by the two Crossfit Bondi members, Carlo and Cora.
The men at Crossfit Bondi had an average maximal oxygen uptake of 50 mL/kg/min, and with a mean biological age of 33 years old, their fitness age corresponded to 24 years of age.
The women at Crossfit Bondi had an average maximal oxygen uptake of 50 mL/kg/min as well, and with a mean biological age of 35, their fitness age corresponded to 18 years of age, making them relative more fit than the men tested.
Tuseday we had a full day of vo2 max testing at Cross Fit Bondi. A fantastic gang who gave it all. Fun to meet so many great people, and test for us a new form of exercise. The results will be presentet at Bondi Fitness Festival on Friday, and today we have analyzed the results and prepared the presentations. If you are in Sydney and wants to join us, buy tickets here!
Meanwihle, enjoy this pictures and video from the testing.
