“…In 28.57% (n=4) the researchers included a comparison group where participants performed whether stretching exercises, conventional physical exercisesor resistance bands exercises. 17,19,21,25 In 50% of the studies there were no statistically significant differences between experimental and control groups.

“…27 On the contrary, in those studies that included a comparison group where participants performed conventional physical exercise (either aerobic or resistance exercise) and stretching, yoga was not superior. 17,22,25 Only in the study of Yagli et al yoga had a greater effect to decrease fatigue in comparison with the conventional physical exercise, which must be interpreted with caution because of the very small sample (20 participants) and, besides, because the authors did not specify the type of exercise in the control group, nor the volume and intensity. 19 In addition, it should be noted that this study was the one that presented the lowest score on the PEDro scale between all of the included.…”

In its most recent report, the International Agency for Research on Cancer revealed that 1.7 million new cases human beings that year. The International Agency for Research on Cancer reported that 1.7 million new cases of breast cancer were diagnosed worldwide in 2012, which represented almost 12% of all cancer types diagnosed in human beings that year. The purpose of the study was to determine if the practice of yoga allows decreasing cancer-related fatigue in women diagnosed with breast cancer. Methodology of the study was taken from database search on Web of Science, Embase, Pubmed, and Cochrane Library, as well as manual reference registration. The eligibility criteria were: (a) randomized controlled trials; (b) measurement of fatigue as main or secondary outcome; (c) studies published until December 2016; (d) studies published in English, Spanish, French or Portuguese. The guidelines of the PRISMA statement were followed. Methodological quality of randomized controlled trials was evaluated with the PEDro scale. Out of the 255 registers found, 14 randomized controlled trials were included. In half of the studies no statistically significant differences were found between experimental and control groups. Only four studies included had a comparative group besides a control group. All studies included were of moderate or high methodological quality according to PEDro scale. Findings suggest that yoga may not be effective to decrease cancer-related fatigue in women diagnosed with breast cancer.

Moderate-quality evidence supports the recommendation of yoga as a supportive intervention for improving health-related quality of life and reducing fatigue and sleep disturbances when compared with no therapy, as well as for reducing depression, anxiety and fatigue, when compared with psychosocial/educational interventions. Very low-quality evidence suggests that yoga might be as effective as other exercise interventions and might be used as an alternative to other exercise programmes.

No conclusions regarding breast cancer-related and all-cause mortality or breast cancer recurrence were possible. However, physical activity interventions may have small-to-moderate beneficial effects on HRQoL, and on emotional or perceived physical and social function, anxiety, cardiorespiratory fitness, and self-reported and objectively measured physical activity. The positive results reported in the current review must be interpreted cautiously owing to very low-to-moderate quality of evidence, heterogeneity of interventions and outcome measures, imprecision of some estimates, and risk of bias in many trials. Future studies with low risk of bias are required to determine the optimal combination of physical activity modes, frequencies, intensities, and durations needed to improve specific outcomes among women who have undergone adjuvant therapy.
