Based on the latest readership survey of ACSM's Health & Fitness Journal®, "You Asked For It" is one of the most popular columns published in the Journal. As its author, David C. Nieman, Dr.P.H., FACSM, steps down after more than 9 years of providing excellent, well-written columns covering a variety of health and fitness issues, it is only fitting to highlight all the questions he's answered over the years. The list below includes the volume and issue numbers along with the question addressed in each issue.

* 9:3 Can exercise help me sleep better?
* 9:4 My daughter is in college and runs, swims, or cycles for at least 2 hours a day in preparation for triathlon events. I am worried that this amount of exercise is too much, especially because she has become quite thin. Can high levels of exercise be harmful to women?
* 9:5 My 13-year-old son wants to start running and lifting weights. Can you give me some exercise guidelines? I'm worried about injury during this time when he is growing so rapidly.
* 9:6 My physician just informed me that I have prediabetes and am at high risk of developing type 2 diabetes. Is there anything I can do to turn this around and prevent future diabetes?
* 10:1 I am a 28-year-old woman, married with children, and weigh 40 lbs more than I should. Obesity runs in my family, especially on my mom's side. Is it possible for me to achieve normal weight, or am I always going to fight being overweight because of my heredity?
* 10:2 Is there anything good about health and fitness in America? It seems that every time I turn on the TV or read the newspaper, I learn something more about how unhealthy we are.
* 10.3 I have two children (ages 8 and 11 years). The summer break is just about here, and I am concerned about their health and fitness. What physical activity recommendations do you support to keep them in good shape?
* 10:4 Every time I walk into a health food store or open a fitness magazine, I see advertisements for antioxidants. These ads claim that I need to ingest antioxidant supplements if I exercise to counter the damaging effects of "free oxygen radicals." Is this true?
* 10:5 My physician says that my high-density lipoprotein cholesterol is too low and my low-density lipoprotein cholesterol is too high. He gave me some medication, but I am more interested in trying to improve my cholesterol numbers by improving my health habits. What do you recommend?
* 10:6 I am 43 years old, and several of my older friends have been told by their physicians that they have osteoarthritis. I'm worried. What can I do to prevent osteoarthritis?
* 11:1 I exercise just about every day and feel great mentally and physically. However, a friend of mine claims that all the time I am spending in exercise will not add up to a longer life. What can I tell him?
* 11:2 What is more important to my health: strong muscles or aerobic fitness?
* 11:3 I exercise vigorously for 1 to 2 hours a day, sweat a lot, and often notice salt residue on my skin after I have cooled down. Do I need to ingest salt tablets to replace the salt I lose in sweat?
* 11:4 I exercise for approximately 30 minutes nearly every day, maintain a healthy body weight, and consume a nutritious balanced diet. However, I am confused about whether moderate alcohol consumption is an additional healthy habit for men like me to follow.
* 11:5 I experienced the flu last winter. What can I do to prevent the flu? Does exercise help?
* 11:6 I am a vegetarian fitness enthusiast but have started training for an Ironman 70.3 (1.2-mile swim, 56-mile bike, and 13.1-mile run). Should I add meat to my diet to ensure adequate protein and iron as I step up my training?
* 12:1 I am eager to lose the extra flab I have built up over the years. My modus operandi is via "Do Lists." Can you provide a list that I can use to become lean?
* 12:2 Several of my friends during the past few years have been diagnosed with breast cancer. What can I do to prevent the onset of breast cancer?
* 12:3 I had a question about aerobic exercise programs. Is it more advantageous to exercise once a day or break this up into two or three shorter segments?
* 12:4 Some of my running partners stretch and others don't, and we have debated the issue several times. Is stretching worthwhile, and if so, what is the best system?
* 12:5 I saw in the news recently that cancer deaths are going up. Why are we not winning the war against cancer? What can I do to lower my risk of getting cancer?
* 12:6 According to my physician, I'm 40- to 50-lbs overweight for my height of 65 inches. He says I need to lose this excess weight if I intend to live a long and high-quality life. I'm confused about what I hear and read from the news media regarding health and overweight. Is excess weight really that bad for your health?
* 13:1 I am 67 years old, prone to getting sick a lot and hoping that a walking program can help. What is the connection between exercise, immune function, and illness for my age group?
* 13:2 I run ultramarathons and enjoy the challenge. However, training for and competing in ultramarathon races is taxing, and my wife claims that over time, my health will suffer. Is there any evidence that being an ultramarathoner is unhealthy?
* 13:3 How do the 2008 Physical Activity Guidelines for Americans differ from previous recommendations?
* 13:4 Can you expose some common myths regarding exercise?
* 13:5 I enjoy energy drinks but wonder if the high amounts of caffeine are harmful to my health. What do you recommend?
* 13:6 I have heard that omega-3 fatty acids are good for your heart, but I am confused about the best way to safely include them in my diet. Should I use supplements or include more fish? Also, can regular use of fish oil supplements help me recover better from hard exercise bouts?
* 14:1 I know my diet is low in fiber from fruits, vegetables, and whole grains, but I am a runner and believe fiber intake is less important for my health than for my less active peers. What do you think - is fiber needed for healthy runners?
* 14:2 Should I eliminate sugar from my diet? I drink a sports drink bottle after each workout. I have read that sugar causes obesity, diabetes, heart disease, mental depression, misbehavior in children, cancer, and immune suppression.
* 14:3 Could you comment on the "calorie rule" that New York City is imposing on restaurants? Will this effort really work to stem obesity?
* 14:4 Is it possible to "feed" and "exercise" your immune system and "boost" its fighting power, as is so often claimed?
* 14:5 Are eggs good for my health and fitness or not? I am very confused because some reports emphasize that eggs provide many good nutrients, whereas others claim that people eating one or more eggs a day die at an earlier age.
* 14:6 I am an avid runner and train 30 to 50 miles per week. So far, I've been running for 20 years and plan to continue as long as I have the motivation. I am worried though that my knee joints are "wearing out" and arthritis will set in. Is this likely?
* 15:1 Is it true that the brain functions better during exercise? When I go for a walk, some of my best ideas are spawned.
* 15:2 What are flavonoids, and do they really protect me from the stresses of a hard workout?
