Brief Summary

Aerobic exercise is associated with many benefits in patients with cancer treatments. Among these, the reduction of cancer-related fatigue (CRF) is one of the best demonstrated. Besides, several animal models have shown a marked reduction in tumor growth with aerobic exercise, sometimes by more than 60%. As the level of physical activity is convincingly associated with a reduction in the risk of cancer or recurrences, this suggests that aerobic exercise may represent a central therapeutic approach during treatment, both against CRF and for its potential anti-tumor effect. Both benefits have been suggested to be based on the immunostimulatory and anti-inflammatory effects of exercise. Indeed, systemic inflammatory activity seems to play a central role in the etiology of CRF during cancer treatments, among other things by stimulating the neuro-inflammatory activity of the central nervous system. Also, regarding the anti-tumor effect of exercise, animal models show that this benefit is partly explained by an increase in the activity of immune cells called natural killers (Natural Killer; NK) in tumor tissue and a reduction in the activity of regulatory T cells, the latter having an immunosuppressive effect. However, in humans, the results vary. While some improvement in NK cell activity has been reported in response to aerobic training in breast cancer survivors, others have seen no effect on the immune profile of patients and survivors. On the other hand, some authors report an improvement in the inflammatory profile with training, while others report little or no effect, as well as weak associations with the perception of fatigue. Although these results seem to discredit the hypothesis of immune and inflammatory regulation of exercise in humans, these studies have all looked at the effect of several weeks of training on the inflammatory and immune profile on an empty stomach and rest. However, several results from the field of exercise immunology convincingly show that the anti-inflammatory effect, as well as the immunostimulating effect of aerobic exercise (including the anti-tumor activity of NK cells) are mainly acute and transient, ie. in the hours following the end of the effort. Furthermore, certain results suggest that in the context of chemotherapy treatments, cyclical treatment by nature, the peaks of fatigue are also acute (i.e. in the days following the treatment) and parallel to peaks of inflammatory activity. Considering these results, it is therefore plausible to assume that the effect of aerobic exercise on suppressing tumor growth and reducing CRF results rather than the repetition of this acute response at each exercise session. In this case, the prescription of aerobic exercise preceding a session of chemotherapy could potentially represent an interesting therapeutic modality, allowing both the reduction of the CRF associated with this treatment, as well as a better response to the treatment. Besides, as this acute response seems to be highly dependent on the intensity of the effort, high-intensity interval training (HIIT) could be a particularly interesting approach in this context, because it does not require that the high intensity or long-lasting exercise. However, considering the immunosuppressive and pro-inflammatory effects of chemotherapy, the extent of the acute response to exercise may not allow this type of therapeutic use to be considered in this population. To date, no study has attempted to characterize the acute immune and inflammatory response following aerobic exercise in patients currently undergoing chemotherapy treatments.

Study Arms (3)

Cancer patients with MRI

EXPERIMENTAL

9 cancer patients will be recruited and received the 3 experimental conditions : first the rest condition (with MRI), then randomly MICE condition and HIIT condition (with MRI).

Other: Resting state (Control); Other: Moderate Intensity Continuous Exercise (MICE); Other: High Intensity Interval Exercise (HIIE)

Cancer patients without MRI

EXPERIMENTAL

9 cancer patients will be recruited and received the 3 experimental conditions : first the rest condition, then randomly MICE condition and HIIT condition, all without MRI.

Other: Resting state (Control); Other: Moderate Intensity Continuous Exercise (MICE); Other: High Intensity Interval Exercise (HIIE)

Healthy patients

ACTIVE COMPARATOR

9 healthy patients will be recruited and received 2 experimental conditions : first the rest condition (with a MRI), then HIIT condition (with MRI).

Other: Resting state (Control); Other: High Intensity Interval Exercise (HIIE)

Interventions

Resting state (Control) OTHER

Participants were asking to sit on a sofa for 50 minutes.

Cancer patients with MRI; Cancer patients without MRI; Healthy patients

Moderate Intensity Continuous Exercise (MICE) OTHER

MICE condition consisted of 50 minutes of moderate and continuous aerobic exercise on ergocycle. This includes a warm-up and cool-down period at low intensity, and a 40-minute period at moderate intensity (power output is equivalent to an effort perception from 4 to 6/10 and lactate levels from 2 to 4 mmol/L, obtained by submaximal test)

Cancer patients with MRI; Cancer patients without MRI

High Intensity Interval Exercise (HIIE) OTHER

HIIT condition consisted of a 30 minutes of aerobic exercise training perform on ergocycle. This includes a warm-up at low intensity, followed by 10 blocks of 1 minute at high intensity (power output corresponding to the highest power reached at the submaximal test and lactate levels \> 4 mmol/L) and 1 minute of active cooldown (effort perception around 1-2/10).
