Abstract
The concepts of exercise as presented in De sanitate tuenda (Care of Health), 1560, written by the Renaissance physician, Girolamo Cardano (1501–1576), were the focus of the inquiry. In this work, as well as in his personal and professional life, Cardano was an advocate of physical activity for the development of physical and mental well-being. The benefits accrued from participation were: the harmonious development of mind and body; good health; emotional stability; a strong, firm, beautiful body; and a long, robust life. Physical exercise was perceived as a lifelong task ranging from childhood to old age, with activities geared for the needs and limitations of each age grouping. Vigorous activities were recommended for both children and youth. As one grew older, moderate physical exercise with longer rest periods was advised. A comparison of this work with Sir Thomas Elyot's Castel of Helth, 1541, revealed that Cardano was significant in the realm of Renaissance exercise for his advocacy of physical exercise for all ages, particularly the forty to seventy age group, as well as for the delineation of appropriate activities for this older adult group.
