Bottom Line: Conversely, the PA intensity correlated only with CRF for women (r = 0.61, P = .003 versus r = 0.39, P = .340 for men).PA explained 55.8 and 5.6% of weight change for men and women, respectively, whereas the corresponding explained variances for CRF were 15.6 and 36.7%.We conclude that PA was associated with change in body weight and CRF; however, there was a trend towards a gender specific effect between severely obese men and women.

ABSTRACT
We aimed to examine the relationship between physical activity (PA) and change in body weight and cardiorespiratory fitness (CRF) in severely obese men and women. Thirty-five subjects (10 men, body mass index 43.2 ± 5.1 kg/m(2)) who participated in a 10-month lifestyle treatment programme were included. The PA duration correlated only with weight change for men (r = -0.69, P = .027 versus r = -0.19, P = .372 for women). Conversely, the PA intensity correlated only with CRF for women (r = 0.61, P = .003 versus r = 0.39, P = .340 for men). PA explained 55.8 and 5.6% of weight change for men and women, respectively, whereas the corresponding explained variances for CRF were 15.6 and 36.7%. We conclude that PA was associated with change in body weight and CRF; however, there was a trend towards a gender specific effect between severely obese men and women.

Mentions: Correlation between the PA duration and weight change was r = −0.33 (P = .050); the correlation between the PA intensity and weight change was r = −0.17 (P = .336). The correlation between the PA duration and the change in CRF was r = −0.04 (P = .853, n = 30); the correlation between the PA intensity and the change in CRF was r = 0.51 (P = .004, n = 30). The relationship between the PA duration and weight change was much stronger for men than for women (r = −0.69, CI −0.88 to −0.41, P = .027 versus r = −0.19, CI −0.60 to 0.26, P = .372). Conversely, the relationship between the PA intensity and change in CRF was stronger for women than for men (r = 0.61, CI 0.10 to 0.85, P = .003 (n = 22) versus r = 0.39, CI −0.29 to 0.86, P = .340 (n = 8)). Scatterplots of PA duration versus change in weight and PA intensity versus change in CRF are shown in Figures 2(a) and 2(b), respectively. There were no relationship between PA duration and WC (r = −0.10, P = .624, n = 28), nor between PA intensity and WC (r = −0.01, P = .967, n = 28).
