Over the past 2 decades, great strides have been made in the field of exercise-oncology research, particularly with breast cancer. This area of research is particularly important since there are >2.8 million breast cancer survivors who are in need of an intervention that can offset treatment-related side effects. Noticeable reductions in physical fitness (ie, cardiopulmonary fitness and muscular strength), negative changes in body composition (ie, increase in body mass, decrease in lean body mass, and increase in fat mass), increased fatigue, depression, or anxiety are some of the common side effects of cancer treatments that negatively impact overall quality of life and increase the risk for the development of comorbidities. Exercise plays a vital role in improving cardiopulmonary function, psychological events, muscular strength, and endurance in breast cancer survivors, and thus should be considered as a key factor of lifestyle intervention to reverse negative treatment-related side effects. The purpose of this review is to address current perspectives on the benefits of aerobic and resistance exercise after breast cancer treatments. This review is focused on the well-established benefits of exercise on physical and emotional well-being, bone health, lymphedema management, and the postulated benefits of exercise on risk reduction for recurrence of breast cancer.

Worksite health promotion programs (WHPPs) aim to improve the health and wellness of employees in an effort to improve health related quality of life (HRQOL). The effect of exercise on improving HRQOL is well documented among clinical populations. However, few studies have examined the effect of WHPPs on HRQOL. The purpose of this study was to investigate the effect of a six-week "Workplace Walk-Off Competition" (WWC) on HRQOL among university employees. One hundred and nine university employees were included in this study (WWC group: n=47, Control group: n=62). All study participants completed the Short Form 12 Question, Version 2 (SF-12v2), a HRQOL questionnaire, before and after the WWC. The SF-12v2 questionnaire determines HRQOL based on two components and reports scores for a physical component summary (PCS) score and a mental component summary (MCS) score. A two-way repeated measures ANOVA was performed on PCS and MCS scores, followed by dependent t-tests for each group. There was no significant difference in PCS or MCS scores between the groups. Further, there were no statistically significant changes in PCS or MCS scores (p>.05) among either group, following the six-week WWC. Although much research deems WHPPs effective for improving many health indicators, this short-term program was not effective in improving PCS and MCS components of HRQOL.
