Body composition, weight, and self‐reported physical activity. A. Change in body composition (kg), presented as mean ± SD. Measured by DXA scan at baseline, after 6 weeks (end of concomitant chemoradiotherapy [CCRT]), after 13 weeks (end of training program), and at 5, 9, and 13‐month follow‐up (respectively 27, 44, and 62 weeks). Grey area shows treatment period. After CCRT, lean body mass (LBM) began to increase, whilst fat mass (FM) continued to decline during the 12‐week training program. At 13‐month follow‐up total body mass (TBM), LBM, and FM had nearly reached baseline values. Change from baseline: **p < 0.01, ***p < 0.001 (significance level was not analyzed at 5 and 9 months follow‐up). B. Major weight loss is seen over the course of CCRT (0–6 weeks) and a continued minor loss after CCRT. Lowest mean weight is seen at the end of the progressive resistance training program (13 weeks). Dark grey line shows mean values, colored area shows ± SD, and light grey line shows the range. C. Scores from leisure time and work were added and presented as mean ± SD. When added a score from 2 to 8 was given; 2 being sedentary throughout the day, 8 being hard physical activity both at work and during leisure time. D. Difference in composition of TBM. At the end of CCRT (week 6) the majority of TBM loss constituted of LBM loss (64%), while at the end of the 12‐week progressive resistance training (PRT) only 32% of TBM loss was accounted for by LBM.
