     Research areas
     Cellular and molecular physiology of muscle tissue: Our
     research on the cellular and molecular aspects of differentia-
     tion, growth and regeneration versus wasting and apoptosis
     is focused on human muscle cells, the laboratory rat model
     and cell cultures, including stem cells. We study cardiac
     muscle cells (after experimental heart attack or in response to
     hypobaric, low oxygen conditions) and skeletal muscle cells
     (after microdamage or muscle wasting induced by surgical
     stress or immobilisation).
     Environment, nutrition and exercise: We study acute and
     long-term adaptations in humans to delayed onset of muscle
     soreness, altered training programmes, oxygen intake or
     nutritional intake. Athletes are studied in the laboratory and
     the field using modern technological devices. The analysis of
     muscle biopsies and immune cells links this field of human life
     sciences to that of the cellular and molecular physiologists.
     Pathology: Selected pathological conditions, such as HIV/
     AIDS, Type II Diabetes and inflammatory conditions such as
     cancer, heart failure and muscle and tendon injuries are stud-
     ied on the patient’s level, as well as on a cellular and molecu-
     lar level in models.

     MPhil and MSc in Exercise Science
     We offer a unique, part-time MPhil in Exercise Science for stu-
     dents holding a degree in Physiology or any related biological
     science (such as medicine, dietetics, physiotherapy, genetics
     or biochemistry).

     A full-time MSc is offered to students with at least three of the
     following as undergraduate subjects: Physiology, Biochem-
     istry, Sport Science and Nutrition. Students must also have
     completed four years of study (either as a four-year BSc or a
     three-year BSc plus a BScHons).

     These two programmes integrate physiology, biochemistry,
