European Prevalence of Diabetes There are about million people with diabetes in the European region, or about 10.3% of men and 9.6% of women aged 25 years and over. There are about million people with diabetes in the European region, or about 10.3% of men and 9.6% of women aged 25 years and over. Prevalence of diabetes is increasing among all ages in the European region (overweight and obesity, unhealthy diet and physical inactivity).

ORGANIZATIONAL PRECONDITIONS Medical check (CV) Type of diabetes  Metabolic syndrome  Body composition (% body fat) Medication Medication  Sulfonyl ureas, etc...  Insulin Scenarios  Obese people  Insulin  Elderly

Scenario 1 : Obese patients recently diagnosed  Intense to moderate aerobic exercise (Daily exercise preferable).  Combined with a caloric restriction to produce a weekly weight loss of ½ to 1 kilo.  At least 1 weekly session of strength training to avoid loss of muscle mass.

Scenario 2 : Patients who have had the condition for some time and have been treated with insulin Bear in mind comorbidities. Bear in mind comorbidities. Programme intermittent exercises, relatively intense strength training exercises and aerobic-type exercises Programme intermittent exercises, relatively intense strength training exercises and aerobic-type exercises Once an improvement in muscle strength and functional performance has been achieved, progress to a more generic intervention programme (with more intense aerobic exercise) Once an improvement in muscle strength and functional performance has been achieved, progress to a more generic intervention programme (with more intense aerobic exercise) Fuente: Praet, SF y Van Loon, LJ; J.

Scenario 3 : Elderly people recently diagnosed with T2DM  Important: Strength training (To avoid or reverse the loss of muscle mass).  Co-intervention with diet Source: Praet, SF y Van Loon, LJ.; J. Appl Phys 103: , Image: Robert Newton. Edith Cowan University

Scenario 4 : Insulin resistant state with no complications  Glycemic control, cardiorespiratory fitness and microvascular function can be improved with a more vigorous programme [including strength training and flexibility] Source: Praet, SF y Van Loon, LJ.
