Portable oxygen to enable high-intensity exercise?
People who struggle to maintain longer periods of physical activity at high intensity may want to consider the option of using portable oxygen.
Sara Stanner, a nutrition expert and part of the Daily Telegraph's LifeCoach team, noted obese individuals may not be gaining sufficient oxygen flow.
"If you are overweight, your heart and lungs have to work harder to supply oxygen to your body," the expert observed.
Ms Stanner was speaking in response to a question from a reader who wished to participate in activities such as swimming, but quickly runs out of breath when taking to the water.
Her comments suggest additional levels of the substance could be beneficial to those wishing to exercise but lack the fitness to do so.
Bettor.com contributor Morgan Freeman recently noted a lack of oxygen is the primary reason why sprinters tend to run out of steam at around the 300-metre mark during races.
