It is true that most people nowadays survive cancer. It is calculated that at least 65 % of people survive at least five years. However, 75-100 % of them experience fatigue, which can last up to ten years after the treatment is over. Now scientists conducted a research, which showed that high intensity interval training is the most effective way to combat this fatigue. This is quite surprising news, because there was a long-held belief that cancer survivors should protect themselves from intensive physical stress and possibility of strains. However, scientist found that bowel cancer survivors can partake in high intensity exercise and experience no serious adverse effects.
It comes with high intensity cardio exercises that work the entire body at once. Hence, they are pretty hard to perform. This way your heart and breath will be high since all the muscles are working.
All the other studies involved a single exercise session. Guelfi et al studied the effects of HIT (repeated 4-second cycle ergometer efforts separated by rest) on blood glucose during exercise and in the immediate 1-hour postexercise period. Participants injected their normal dose of insulin and had breakfast. After the postprandial peak in blood glucose, on alternate days, participants either exercised or rested. During exercise blood glucose declined more rapidly as compared to the nonexercising controls, indicating that high intensity exercise may increase the risk of hypoglcemia. This finding is not supported by the other studies reviewed. However during the recovery period blood glucose levels continued to decline in the controls while remaining stable in the exercise group suggesting a decreased risk of postexercise hypoglycemia. Guelfi et al also compared a HIT protocol that was combined with moderate-intensity exercise (repeated 4-second cycle ergometer efforts over 30 minutes separated by cycling at 40% VO2max) to moderate exercise only (cycling at 40% VO2max) for 30 minutes. Exercise commenced 3.5 hours postprandially when the blood glucose was about 11 mmol/L. Blood glucose fell to a greater extent in the moderate exercise group compared to the HIT group, and remained stable in the HIT group in the 1-hour recovery period while continuing to fall in the moderate-exercise group. Blood glucose at 1-hour postexercise was 3.3 mmol/L lower than the pre-exercise level in the HIT group, and 6.3 mmol/L lower in the moderate exercise group (P = 0.021). However, Maran et al, using a similar exercise protocol, demonstrated that following morning HIT, blood glucose was significantly lower between midnight and 6 AM the next day compared to when only moderate-intensity exercise was done. Mitchell et al showed that continuous noninterval exercise at 80% VO2max until exhaustion (approximately 10 to 13 minutes) increased blood glucose during and in the 2-hour postexercise period. Thus, unlike moderate-intensity exercise, HIT is unlikely to cause hypoglycemia during or immediately postexercise in type 1 diabetics, but 14 to 20 hours later it may result in lower glucose levels.
A group of volunteer school children, 10 girls and 47 boys, were recruited, and were randomly divided into a moderate exercise group and a high intensity exercise group.
