A few 30 second sprints as beneficial as hour long jog

01.06.2005


Just six minutes of intense exercise a week could be as effective as an hour of daily moderate activity suggests new findings from researchers at McMaster University.



"Short bouts of very intense exercise improved muscle health and performance comparable to several weeks of traditional endurance training," says Martin Gibala, an associate professor in the department of kinesiology of McMaster.

The research, which is published in the June edition of the Journal of Applied Physiology, found that performing repeated bouts of high-intensity "sprint"-type exercise resulted in profound changes in skeletal muscle and endurance capacity, similar to training that requires hours of exercise each week.


The study was conducted on 16 subjects: eight who performed a two-week sprint interval training program and eight who did no exercise training. The training program consisted of between four and seven 30-second bursts of "all out" cycling followed by four minutes of recovery three times a week for two weeks. Researchers found that endurance capacity in the sprint group increased on average from 26 minutes to 51 minutes, whereas the control group showed no change. The muscles of the trained group also showed a significant increase in citrate synthase, an enzyme that is indicative of the tissue’s ability to utilize oxygen.

"Sprint training may offer an option for individuals who cite "lack of time" as a major impediment to fitness and conditioning," said Gibala. "This type of training is very demanding and requires a high level of motivation, however less frequent, higher intensity exercise can indeed lead to improvements in health and fitness."

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
