![]() ![]() Alternate the change of direction with each cone. You run straight toward the first cone and then rapidly change direction by running to its outside on the right and continuing this practice by running toward the next cone and running on its left side. Place the cones alternately on the right and left sides of the track. If you have a basement or if you can do this outside, then make yourself a track with five or more cones. What can I do? – R.B.ĪNSWER: This is a question better answered by a basketball coach, but I’ll give it a try. I can shoot well and run fast, but I’m no good at side movement. DONOHUE: One thing I am not good at in basketball is moving to the side. They should exhale while they are lifting the weight, and inhale while they return the weight to the starting position.ĭEAR DR. Doing so impedes blood return to the heart. They should not hold their breath while straining to lift. Forty-eight hours should elapse before they exercise the same muscle.Īll children, regardless of age, should have instructions in proper form when lifting. They should take a two-minute break between sets of consecutive lifts. They should not add more weight until they can lift a weight 12 times in a row. ![]() They should lift a weight that they can raise eight times consecutively without straining. They shouldn’t turn it into a contest of who can lift the heaviest weight – that’s an invitation to injury. Older children must exercise common sense as well as their muscles when they’re lifting weights. They need instruction, and they need someone with a cool head who won’t allow them to overdo it. ![]() DONOHUE: Would you give some ideas on how young boys can lift weights safely? – C.P.ĪNSWER: Children 12 and younger should lift weights only under supervision. I’m glad you’re seeing your doctor.ĭEAR DR. The piece might have been swept into a brain artery, where it temporarily blocked blood flow. You might have dislodged a piece of clot in the neck artery. If they can’t feel the pulse there, they can put a hand over their heart and count the heartbeat. People can learn to take their pulse by feeling it on the thumb side of the wrist. I try to discourage this practice because of the very thing that happened to you. Millions of people take their pulse by feeling their carotid arteries. Doing it unknowingly and doing it when alone can be dangerous. Doctors sometimes massage the carotid sinus to put an end to a rapid heartbeat. You could have pressed on the carotid sinus and triggered heart slowing or heart stoppage, along with a drop in blood pressure. If blood pressure is too high or if the heart is beating too quickly, the carotid sinus detects the changes and sets in motion a reflex that slows the heart and lowers blood pressure. It monitors blood pressure and heartbeat. In that artery is a small area called the carotid sinus. There’s a carotid artery on either side of the neck. Is it possible to apply too much pressure to the neck and effect something similar to what I experienced? – D.T.ĪNSWER: The carotid artery in the neck brings blood to the brain. I didn’t go to the hospital, but I have made an appointment with my doctor to discuss this. ![]() The episode lasted about 15 seconds, and then everything returned to normal. After counting for six beats, like a flash, my right arm went numb and my right leg buckled as I went to my knees. I had to press rather hard to find the pulse. I did so by pressing two fingers on my left neck artery. Normally a walk like the one I was taking would raise it to 110.
