Hey, there hope this helps
Explanation: Both types of hurdle stretches loosen up the hamstring in the same way. But the hurdle stretch with the leg pointed back puts sideways torque on the back knee and can result in serious injury. So while the potential benefit of the exercises are the same, one risks serious injury to the knee.
Good luck :3
I think b would be the most effective solution

Answer:
The correct answer to the question: The safe residual pressure is always:___, would be: 200 psi.
Explanation:
Portable oxygen that is placed in cylinders has become a great resource for people who are oxygen dependent, but wish to maintain a certain level of independence. However, it is important to understand that these cylinders must be managed in accordance with series of factors, and variables, that will make the use of them safe por a patient. One such really important variable is the residual pressure within a cylinder, which means the pressure exerted by the oxygen available still in the cylinder as it flows. Universally it is accepted that the minimum level of this residual pressure must be 200 psi (pounds per square inch) and once it reaches here it means that once that levels has been reached, it is no longer safe to use that cylinder anymore.
Warming up is important because you need to "warm up" your core and muscles and gets the blood flowing in preparation of a strenuous workout. It also helps prevent the risk of injury.
Stretching, walking, jogging, arm circles, lunges, squats and jumping jacks are good choices to include in a warm up
