However, excessive exercise that exhausts the adaptive reserve of the body or its ability to positively respond to training stimuli can induce tissue damage and dysfunction of multiple organs and systems. Tissue injury, inflammation, and oxidative stress are reportedly induced in the skeletal muscles, liver, and kidneys after exercise. However, the precise mechanisms underlying acute tissue injury after intense exercise have not yet been fully elucidated. Studies using various experimental models of acute tissue injury, other than intense exercise, have demonstrated infiltration of inflammatory cells, including neutrophils and macrophages. These cells infiltrate injured tissues and induce inflammatory and oxidative stress responses by producing inflammatory cytokines and reactive oxygen species, thereby exacerbating tissue injury. In addition to the activation of blood neutrophils and increase in their levels during and/or after prolonged or intense exercise, chemokines that contribute to leukocyte migration are released, facilitating the migration of neutrophils and monocytes into tissues. Therefore, neutrophils and macrophages, activated by exhaustive exercise, may infiltrate tissues and contribute to exhaustive exercise-induced tissue injury. Recently, the contributions of neutrophils and macrophages to various tissue injuries caused by exhaustive exercise have been reported. In this review, we summarize the involvement of neutrophils and monocytes/macrophages in exhaustive exercise-induced non-skeletal muscle tissue injury. In addition, we present novel data demonstrating the contribution of neutrophils and macrophages to exhaustive exercise-induced cardiac and pulmonary injuries.

However, several factors can decrease the immunostimulatory efficacy of chemotherapeutic agents. These include reduced tumour cell antigenicity and adjuvanticity and compromised immune function at a local and systemic level. Findings from preclinical studies show that dietary restriction and exercise promote systemic changes that may help to restore immune system function through several mechanisms, including an enhanced infiltration and function of antitumoral immune cells and a decrease in immunosuppressive cells, leading to a reduction in tumour volume. In addition, dietary restriction and exercise training in mice have been shown to enhance the efficacy of chemotherapy. In human studies there is also emerging evidence that dietary restriction and exercise can impact the immune system towards a more antitumoral profile. In this review, we discuss the immunostimulatory effects of dietary restriction (caloric restriction and fasting) and exercise training in preclinical cancer models, and potential synergies with chemotherapy.

The initial aim of the review was to investigate the T-cell specific mechanisms of exercise which affect clinical/disease outcomes in skin cancer. Study quality was assessed by a modified Covidence quality assessment template with animal-model study specific criteria. A total of 10 articles were included; all articles were murine model studies investigating melanoma. Eight studies (n=8) employed a randomised controlled trial design, with two bio-informatics studies, and one study using human data which could solidify a link to human health. While the review focussed initially on T-cells, many studies reported significant changes in NK cells, and as they share the same haematopoietic lineage/ common lymphoid progenitor as T cells, the data was included in the analyses. Most studies indicated that exercise reduced melanoma tumour burden. Exercising prior to melanoma inoculation was most effective for delaying carcinogenesis and reducing tumour burden. Synergism was a topic identified in studies; PD-1/PD-L1 treatment, and exercise were not synergistic. Conversely, exercise and mental stimulation were synergistic, and the temperature at which exercise was conducted significantly reduced tumour burden. Several murine studies reported that exercise improved clinical outcomes in melanoma, and that long-term exercise was more effective in reducing tumour burden.
