No Time To Exercise? Then This Training Programme Might Be For You

TheWhen it comes to exercise, whats your excuse? Whether its lack of time, fund or motivating sometimes the lure of the sofa can merely be too strong it can be all too easy to put off that run for another day. But whatever your reason, its still recommended that adults aged between 19 and 64 should be getting at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity workout a week. This approximately is currently working at about half an hour of brisk walk-to or cycling five times a week.

While this doesnt sound like a lot of exercise in the grand strategy of things, research presents that you could actually do even less workout and still preserve a good level of fitness with the use of high intensity interval develop( HIIT ).

A typical HIIT session involves doing multiple intervals, or explodes of relatively short, intense exercise separated by rest or light workout, and can last anywhere between a few minutes, right up to half an hour. It tends to involve many forms of exercise such as cycling, operating or even resistance based train. All of which can be completed in a typical gym or health club setting.

Although high intensity interval train has been around for a while, it is receiving increased attention from researchers. This is because of its period efficient approach and the many health benefits it can offer such as increased cardiovascular fitness, lower blood pressure and improved blood outcomes like glucose tolerance how the body deals with sugar throughout the day and good cholesterol.

The downside of the typical HIIT programme is the intensity of the exert HIIT sessions usually involve maximal sprints such as running or cycling as fast as you can, for 30 seconds. These sprints can be tough to complete especially for a lesser trained participant. This means that although HIIT is effective at improving fitness, lots of people are put off actually doing it because of the intense levels of exercising required.

A Different Approach

This is why at the University of Hull we have developed a modified HIIT program which offers the important health benefits often links with prolonged exercising, while saving hour and being easier to complete. In our research, we employed lower intensity, longer intervals for the protocol which are different to the short, very intense intervals of traditional HIIT.

The programme involves a 28 -minute HIIT workout on a stationary bike, featuring five two minute intervals, with only ten minutes of hard work, and the remaining 18 minutes light exert. Over six weeks, we compared three sessions a week of our 28 -minute HIIT protocol, with a continuous moderate intensity cycling programme and a gym based resistance exert programme which were both 55 minutes in length.

We discovered that our 28 -minute HIIT programme devoted the same fitness improvements as the longer 55 -minute moderate intensity cycling conferences. This was indicate as a fitness increase of 13% over six weeks and was measured by a VOmax test of participants before and after the six-week training intervention. This exercise exam allows us to measure how well the body is able to deliver oxygen to, and use oxygen in the working muscles during exercising. The higher the participants oxygen consumption( VOmax ), the fitter the participant is. So of course we would expect this value to increase after completing an exercise training intervention.

Getting Fit With HIIT

Our training study adds to the growing body of evidence which suggests HIIT is effective at improving markers of health. Although it is still unclear why exactly HIIT runs so effectively, researchers have been able to show that it activates similar biological pathways and mechanisms traditionally related to endurance kind exercise such as an increase in muscles ability to use oxygen.

But while HIIT does appear to be effective at improving markers of health, more research especially larger studies looking at the safety, adherence rates and participant pleasure are required. These examines could examine the real world potential and be applied in HIIT, as much of the present research is conducted under controlled laboratory conditions.

So while it is clear there is still a lot that is unknown about HIIT, what is known is that by means of a modified HIIT protocol you may be able to increase your fitness while spending less period at the gym. And in a time poor world, where more people need to engage in regular physical activity, that is definitely not a bad thing.
