Primary data from three different cancer populations: breast, prostate, and lung, will be examined. A number of experimental studies have been conducted to confirm the effectiveness of resistance training on pain relief as well as the biochemical pathways that relate to this process. In this review, we will examine 5 randomized controlled trials. For the purposes of this review, pain is defined as physical suffering or discomfort associated with illness. Pain is the body’s natural signal, bringing attention to damage that has been sustained by tissues. However, chronic pain is common in the cancer population, and often serves no good purpose but instead will negatively impact both physical and mental health. The three types of pain: nociceptive, neuropathic, and inflammatory pathways have been investigated, and the knowledge of pain mechanisms allows for the understanding of how it is associated with pain. The purpose of this exploratory literature review is to give insight on how to maximize pain-relieving effects of resistance training. Research has indicated that resistance training modulates pain pathways by upregulating the release of pain-relieving substances including beta-endorphins, anti-inflammatory cytokines, and endocannabinoids. Understanding of the benefits of resistance training may be useful in relieving cancer pain, and reproducing effects of pain-relieving strategies while minimizing the symptoms related to cancer and its treatment.展开更多

However, no study has evaluated the safety and benefits of exercise in relapsing polychondritis. Aim: To evaluate the effectiveness of an exercise training program in a patient with relapsing polychondritis. Case presentation: A 67-year-old female patient with relapsing polychondritis in remission was submitted to a 12-week, twice weekly, aerobic and resistance training program. Aerobic capacity, muscle strength and function capacity, as well as body composition, were evaluated at baseline and after 12-weeks. Conclusions: Exercise training program demonstrated to be effective for increasing aerobic capacity, muscle strength and function, and for improving body composition in the patient. Further studies are necessary to confirm these findings.展开更多

Exercises, including resistance training, Ti-chi and yoga surprisingly show various and promising outcomes. We present an unusual case which certain aerobic techniques over a period of 5 weeks have improved a patient’s myocardial contractility and overall function after sustaining an anterior myocardial infarction.展开更多

This study is characterized as observational of comparative cross-sectional design. The sample was composted by young women, trained at least for three months, without health complications. Maximum strength (1RM) and endurance muscular (repetition at 60% 1RM) of the lower limbs were evaluated in knee extension exercise, unilaterally. Overall quality of life and in four domains was evaluated by the WHOQOL-bref. Data were described by mean and standard deviation values. Outcomes were compared by independent t-test, adopting a significance level (α) of 0.05. Thirty women were evaluated (isolated gymnastic (IG), n = 15;30.13 ± 7.24 years—combined gymnastic and strength (CG), n = 15;29.46 ± 8.18 years). Similarly values were found among groups for all outcomes (p > 0.05). The results suggest that the association of strength training with gymnastics training, possibly accumulating excessive training volume, may not increase the levels of maximum strength, endurance muscular and quality of life in young women.展开更多
