High-intensity exercise found safe and effective in long-term heart transplant recipients

18.08.2014

High-intensity exercise can help stable heart transplant patients reach higher levels of exercise capacity, and gain better control of their blood pressure than moderate intensity exercise, investigators report in a new study published in the American Journal of Transplantation.

Recent research shows that high-intensity interval exercise—training for a few minutes at close to the maximum heart rate—is safe and more efficient than moderate exercise for improving exercise capacity in different groups of patients with heart disease.

Researchers led by Christian Dall, PhD fellow, MSc, of the Bispebjerg Hospital at the University of Copenhagen, Denmark, investigated whether people who have received a new heart gain similar benefits from high-intensity interval training, or whether they should exercise at moderate intensity as currently recommended.

The team compared the effects of 12 weeks of high-intensity interval training versus continued moderate training in 16 stable heart transplant recipients who had been living with their new heart for more than one year.

The trial revealed that high-intensity interval training is safe in heart transplant patients, and the effect on exercise capacity and blood pressure control is superior to moderate intensity training. VO2 max, or maximal oxygen uptake, increased by 17 percent in patients performing high-intensity interval training compared with 10 percent in patients performing continued moderate training.

Systolic blood pressure decreased significantly in patients in the high-intensity group, while it remained unchanged in patients in the moderate intensity group. Peak heart rate also increased in the high-intensity group but not in the moderate intensity group. Heart rate recovery improved in both groups.

"Today, people who have been given a new heart experience increased physical function, quality of life, and overall life span; however, most patients continue to have limitations in their physical function and reduced quality of life compared to the general population due to side-effects from anti-rejection medications and because heart rate regulation is impaired after heart transplantation," said Dall.

"The impaired heart rate response has been considered a hindrance for more demanding high-intensity training, but this new study documents that stable heart transplant recipients benefit from this type of training more than from the moderate training that has been recommended so far. Importantly, the training is also safe and well received by patients."

The findings may be especially encouraging for athletes who compete in the Transplant Games of America, whose most recent event was held earlier this month in Houston, and those training for upcoming summer and winter World Transplant Games.

In an accompanying report, investigators provide a summary of a two-day meeting held in April 2013 in Toronto, Canada, in which a group of clinicians, researchers, administrators, and patient representatives discussed key issues related to exercise in organ transplant recipients.

The attendees developed a list of top research priorities and a research agenda for exercise in solid organ transplant, which includes the need to conduct large multicenter intervention studies, standardize measures of physical function in clinical trials, examine the benefits of novel types of exercise, and assess the effects of exercise on measures such as immunity, infection, and cognition.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
