Twenty-five years of research on the effects of exercise training in breast cancer survivors: A systematic review of the literature

AIM To investigate the role of exercise training the past 25 years on major physiological-psychological outcomes studied thus far in this patient population. METHODS PubMed, MedlinePlus, the Cochrane Library, Web of Science, SportDiscus, Embase, Scorpus, and Google Scholar were searched from September to November 2013 to identify exercise training studies that used objective measurements of fitness and/or patient reported outcomes assessed pre and post-exercise training with statistical analyses performed in at least one of the following outcome measurements: Cardiorespiratory function, body composition, muscular strength, fatigue, depression, and overall quality of life. Five reviewers independently identified the studies that met the criteria for the review and discrepancies were resolved by consensus among all authors. RESULTS Fifty-one studies were included in this review with 5 from the period between 1989-1999, 11 from 2000-2006, and 35 from 2007-2013. The evolution of study designs changed from aerobic only exercise training interventions (1989-1999), to a combination of aerobic and resistance training (2000-2006), to studies including an arm of resistance training or examining the effects of resistance training as the main mode of exercise (2007-2013). Overall, the benefits of exercise showed improvements in cardiorespiratory function, body composition, strength, and patient reported outcomes including fatigue, depression, and quality of life. CONCLUSION Exercise training appears to be safe for most breast cancer patients and improvements in physiological, psychological, and functional parameters can be attained with regular participation in moderate intensity exercise.

The feasibility of an 8-week, home-based isometric strength training program for improving dressage test performance in equestrian athletes

The aim of this study was to determine the feasibility of an 8-week, home-based isometric strength training program in equestrians. Also, we examined changes in muscular strength, endurance, and riding performance. 18 riders (≥1 year dressage experience, riding ≥1 h/week, otherwise untrained) completed pre-/post-muscular tests and a US Equestrian Federation Training Level Rider Test. A progressive, 3 day/week riding-specific intervention using TheraBands® was implemented. Feasibility was determined as >50% of riders completing ≥18/24 sessions of ≥2 sets/exercise of prescribed volume. Dependent samples t-tests compared pre/post composite muscular strength/endurance, and riding test scores. 55.5% of riders completed ≥75% exercise sessions. Significant improvements were observed for muscular endurance (pre 149.8±82.2, post 209.2±112.2; P=0.003), and for riding test scores (pre 57.8±7.4, post 60.8±5.1; P=0.037). Exploratory analyses revealed a significant correlation between improvements in muscular endurance...
