Just 30 minutes exercise a day could reduce deaths from heart disease

01.02.2005


Currently around one in five menopausal women die from heart disease. But according to new research by exercise scientists at Liverpool John Moores University (LJMU), this shocking statistic could be reversed if women took just 30 minutes exercise, five days a week. The findings are based on the initial results of a 12-month study of 24 60-year-old postmenopausal women.



Professor Tim Cable, Director of LJMU’s School of Sports and Exercise Sciences explained: “In the same way that we need to think about a pension plan, women need to need to invest in their health and fitness now to ensure a real quality of life in later years. 2005 could be the time to start this action plan.”

The study was designed so that the scientists could assess the effects of well-defined aerobic exercise on the women’s cardiovascular system. No other research project has looked at so many different aspects at the same time – from changes in body composition to the performance of the heart and the supply of blood to the muscles and skin of the arms and legs.


Before starting the exercise programme, each of the women volunteers had their bone density measured along with the amount of muscle and fat in their bodies. Next their physical fitness, blood pressure and heart pumping capacity were measured while they were exercising on a treadmill.

An ultrasound technique – Echocardiography – was used to measure the size of the chambers and the thickness of the muscular walls of the heart. Then the movement of blood through the large elastic arteries into the smaller blood vessels found in the muscles and skin of the limbs was monitored.

Dr Keith George, Reader in Cardiovascular Physiology, said: “The volunteers have been terrific, with their enthusiasm and commitment to complete the programme and get themselves much fitter. Most of the ladies have not undertaken any significant exercise since leaving school some 45 years earlier and it would have been so easy for them to give up because of insufficient time or other pressing commitments.”

This series of tests was repeated every three months to determine the impact of the exercise programme and to determine which part of the body was benefiting most. The exercise sessions involved walking and cycling to meet individually established heart rate targets for 30 min a day, 5 days a week. The initial level of exercise was set deliberately low to avoid any injuries before being built up in controlled stages as the study progressed to challenge their bodies.

A very clear sequence of beneficial changes quickly became apparent as the exercise programme went on. After only a short time the women felt mentally and physically much better and this improved sense of well-being was backed up by increases in their measured levels of fitness.

Professor Tim Cable explained: “Although we expected to find improvements in blood flow to the limbs before changes developed in the heart, we were extremely surprised to find how little exercise was required to improve the flow of blood to the muscles and skin of the arms.”

With 2 months left in the research programme, Professor Cable predicts even greater benefits. “We expect to see improvements in the performance of the heart itself. Like most scientific research this study has raised as many questions as answers, and they will keep us busy in the future if we can obtain the right sponsorship.”

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
