Abstract

Evidence from recent publications indicates that repeated exercise may enhance the quality of life of cancer patients (Maddocks et al., 2012). Regular physical activity may attenuate the adverse effects of cancer therapy, prevent or reverse cachexia and improve survival, although not all the patients are able or willing to undertake programs currently being offered. The aims of this study were to analyze: i) the effects of a progressive endurance exercise (progressive Training, pTR) on survival and cachexia in sedentary (SED) mice inoculated (I) with a fresh fragment of solid C26 tumor [SED-I-pTR; SED-I-SED]; ii) the effect of different protocols of endurance exercise (Trained for 30 min, TR30; Trained for 60 min, TR60; Trained for 120 min, TR120) on survival and cachexia in trained mice inoculated (I) with a fresh fragment of solid C26 tumor [pTR-I-TR30’; pTR-I-TR60’; pTR-I-TR120’]. All the conditions were tested to evaluate the gender (male and female) and age differences (young, 7-weeks old; adult, 3-months old; old, 15-months old). Mice were trained on a rota-rod for 6 weeks (5 times per week). Male sedentary mice (SED-I-SED) showed a higher median survival than sedentary female mice (for each age group); moreover adult mice survive more than sedentary young and old mice (for both gender groups). The endurance training improved the survival of mice in which the tumor was more aggressive (young and old), especially in female mice. Moreover, in the female old mice the progressive training exercise conducted before the inoculation seems to prolong survival. The data suggest that the endurance exercise as adjuvant therapy in cachexia needs to be gender and age specific.
