Background and Objective: Breast cancer and related treatments induce various physical symptoms. One of suggested method for preventing or reducing physical symptoms is exercise training. This study was done to evaluate the effect of 8 weeks Pilates exercises physical fitness indices in breast cancer patients.
Methods: In this randomized clinical trial study 30 female breast cancer patients were divided into intervention (n=15) and control (n=15) groups by block randomization method. Pilates exercise for 8 weeks, 3 days a week for 60 min in every session was performed in Patients in interventional group but patients in control group did not participate in any regular physical activity. Flexibility, coordination, back and hand strength and muscular strength were determined using Wells, alternate hand wall toss, one leg –stance, back and handgrip dynamometer, sit up tests, respectively.
Results: Pilates exercises significantly increased flexibility, balance, coordination, back and hand strength, muscular endurance and sit up in interventional group in compared to controls (P<0.05).
Conclusion: Pilates exercise improves physical fitness indices in women with breast cancer.

Background and Objective: Physical exercise and nutrition supplements are recommended interventions to reduce cachexia. This study was conducted to determine the effect of resistance training and resveratrol supplementation on muscle regeneration indices of MyoD (myoblast determination protein) and eMHC (embryonic Myosin Heavy Chain) in CT-26 colon cancer mice.
Methods: This experimental study was performed on 20 six-week-old BALB/c mice to which CT-26 tumor was implanted. The mice were divided into four groups of resistance training, resveratrol, combination of resveratrol with resistance training, and control. The resistance training group performed six weeks of progressive resistance training. The resveratrol group received 100 mg/kg resveratrol per day, and the control and resistance training group received the solution of Methyl cellulose through gavage. In gastrocnemius muscle MyoD protein and eMHC level were measured using western blot and ELISA methods, respectively.
Results: eMHC protein in combination of resveratrol with exercise group (4.66±0.25) increased significantly compared to the exercise group (3.46±0.64) (P<0.05). Body weight of mice without tumor (21.50±1.30) in the resistance training group increased significantly compared to other groups (P<0.05). There was no significant difference in the tumor weight of mice and MyoD protein in expermental groups.
Conclusion: Regarding the increasing effect of combination of resveratrol with exercise group compared to resistance training group on eMHC, resveratrol supplementation at higher doses may be recommended along with resistance training to improve muscle regeneration.
