Arina Engelbrecht from Organisational Development and Employee Well-being believes physical activity has a number of benefits for one’s health, including stress relief.

Being physically active plays a big role in preventing the development of mental-health problems and in improving the quality of life of people experiencing mental-health problems.

Treatment for depression

Physical activity can be an alternative treatment for depression. It can be used as a stand-alone treatment or in combination with medication and/or psychological therapy. It promotes all kinds of changes in the brain, including neural growth, reduced inflammation, and new activity patterns are formed that promote feelings of calm and well-being. It releases endorphins – powerful chemicals in the brain that energise your spirit and make you feel good.  

Physical activity can be very effective in relieving stress. Research in adults has found that physically active individuals tend to have lower stress levels compared to individuals who are less active.  It also leads to improved sleep. When a person sleeps better and feels more rested, overall quality of life improves. They cope better with daily life stressors.

Reduce Alzheimer's risk

Regular physical activity can reduce your risk of developing Alzheimer's disease by up to 50%. It can also slow down further deterioration in those who have already started to develop cognitive problems.  It stimulates the brain’s ability to maintain old connections as well as to make new ones.

A study asked people to rate their mood immediately after periods of physical activity (e.g. going for a walk/run, cycling, doing housework) and periods of inactivity (e.g. reading a book or watching television). Researchers found that participants felt more content, more awake, and calmer after being physically active compared to after periods of inactivity.

In conclusion, people who are physically active feel a sense of well-being, feel more energetic throughout the day, sleep better at night, have sharper memories, and feel more relaxed and positive about themselves and their lives.

“Being physically active not only changes your body, it changes your mind,
attitude, and your mood.” – Arina Engelbrecht

SARChI Chair on disease resistance and quality in field crops awarded in UFS Department of Plant Science
2016-02-01

Description: SARChI Chair Tags: SARChI Chair

Prof Labuschagne

A South African Research Chairs Initiative (SARChI) chair has been awarded in the Department of Plant Sciences at the University of the Free State (UFS). The chair will be headed by Prof Maryke Labuschagne, and will focus on crop quality breeding and disease resistance in field crops.

The disease resistance research by the chair will be headed by Prof Zakkie Pretorius. The disease resistance breeding will be a continuation of the internationally-acclaimed wheat rust research that Prof Pretorius has been conducting during his career.

The quality breeding will focus on crop protein quantity and quality as well as on iron, zinc, and beta carotene biofortification of staple crops such as wheat, maize, and cassava.

Prof Labuschagne believes that food security is one of the key factors for stability and prosperity on the continent. Her research and that of her students focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she said.

Last year, one of  Prof Labuschagne’s PhD students, Bright Peprah, received an award for $473 000 from the competitive Program for Emerging Agricultural Research Leaders (PEARL) of the Bill and Melinda Gates Foundation for his project on improving the beta-carotene content in cassava.

Prof Labuschagne also received the prestigious ‘Continental Lifetime Achiever Award’ from Africa’s Most Influential Women in Business and Government Programme (MIW) last year for her commitment and continuous contributions to food security. She is an NRF-rated researcher, and author or co-author of over 160 articles in accredited journals.

Research Chairs have been designed by the Department of Science and Technology, together with the National Research Foundation, to attract and retain excellence in research and innovation at South African public universities.
