Sample characteristics
The participants’ mean age was 63.2 years (SD = 7.6, range 36–76), and 54.9% of the sample was female. The average duration of known type 2 diabetes was 10.6 years (±6.6, 3–36). Based on the World Health Organization classification of obesity,32 the study sample included 32.9% overweight (BMI = 25–29.99), 33.7% obese grade I (BMI = 30–35), and 33.4% obese grade II (BMI > 35) subjects. Furthermore, 61.3% of the sample achieved the minimally recommended activity level of 1.000 kcal per week (32.7% did not achieve this level, and 6% did not answer all questions on the FFkA). To establish the level of 1.000 kcal, the author was guided by a review of Warburton et al33 on the health benefits of PA.
On average, the sample was low in cardiovascular fitness and showed very poor endurance results. According to criteria by Oja et al,28 77.7% were classified as “weak” or “very weak”, 11.1% reached a medium performance level, and 11.2% proved to be “good” or “very good.”
Participants with a BMI of 25–30 (age: 66.2; SD = 5.5) were older than individuals with a BMI > 35 (age: 59.8; SD = 8.7), which proved to be significantly different (P < 0.001; F = 22.780; 2 = 0.120). In the group with BMI > 35, there were significantly more men than in the two other BMI classes (P < 0.01; F = 5.045; 2 = 0.028). Significant negative correlations were found between BMI and sex (r = 0.097; P < 0.05) and between BMI and age (r = 0.359; P < 0.01).
Duration of diagnosis was associated with age (r = 0.182; P < 0.05) and with physical role function (r = 0.148, P < 0.05).
From the Results section, the range for age was:
36 years
40 years
63 years
76 years
36 years
40 years
63 years
76 years
Explanation / Answer
From the Results section, the range for age was:
