Introduction:
Cancer is amongst the leading causes of death worldwide. A total of 19.3 million new cases were diagnosed in 2020. Cardiovascular impairment is the second leading cause of death in patients undergoing cancer treatment. By measuring the maximum rate of oxygen consumption (VO2max) in cancer patients, it is possible to estimate their cardiorespiratory health. This study aims to show how participants' VO2max increases with a therapeutic physical exercise programme.
Methods:
Four databases were used for the literature search. Twenty-eight studies were analysed using the inclusion and exclusion criteria. The quality of these studies was analysed with the PEDRO scale. The structural characteristics of the articles and the study variable (VO2max) were studied.
Results:
The VO2max of the 2558 patients studied presents some variations by gender, intervention and moment of measurement. For male-associated cancer, the increased VO2max ranged between 1.5 and 4.2% after the intervention. The increase in the maximum VO2max in female-associated cancer was between 0.3 and 53%. Different types of cancer for both genders presented an oscillation between 0.5 and 3.47%.
Conclusions:
Therapeutic physical exercise is an efficient intervention to improve the VO2max in oncology patients. The results show that a therapeutic physical exercise intervention lasting 12 weeks, 3 days per week with a moderate-vigorous intensity, increases the VO2max in oncology patients.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
