True or False: Females are genetically predisposed to bulking up if they start lifting weights?

Posted on October 19, 2016


While strolling through the magazine isle at her local super- market, Amanda happened to glance at the cover of a female bodybuilding magazine. She stared in near disbelief at the size of the woman on the cover. Her muscles were huge! Her veins were bulging! She looked more like a man than a woman.

Earlier that week, Amanda had found an article touting the benefits of resistance training. She had read that lifting weights can help decrease body fat, strengthen muscle and bone, help prevent injuries and have a positive impact on balance. She was actually considering a visit to her local fitness center to talk about getting a membership, but not now—not after seeing the cover of that magazine!

Regretfully, many women believe that if they start lifting weights, their thighs, biceps and shoulders will almost immediately be transformed into giant slabs of bulking muscle. In reality, it is difficult to gain significant muscle mass from lifting weights, a truth for both men and women. However, it is particularly difficult for women to gain muscle mass, as they have much less testosterone than do  men.

Think about it: You likely have friends and family members who participate in resistance-training exercises. They lift weights on their own, and they attend strength-training classes, often with friends. Maybe you even know someone who attends those dreaded 5 a.m. boot-camp classes, where participants are forced to do thousands of squats, lunges and pushups to the point of exhaustion!

Few of these individuals have muscles that resemble those of the people you see on bodybuilding magazine covers. When you see pictures of women with huge muscles, you can almost bet that performance-enhancing drugs are involved.

It is true that women who engage in resistance training activities usually get stronger; those gains in strength are often similar to gains realized by men, as long as the training programs are similar. In their book Physiology of Sport and Exercise, authors Wilmore and Costill (2004) report on research showing that women can gain considerable benefit from strength-training programs, even though strength gains are usually not accompanied by large increases in muscle bulk. They also write that hypertrophy (increase in muscle size) is neither a necessary consequence of nor a prerequisite to gains in muscle strength.

I’ve worked in the fitness arena for nearly 20 years and can think of dozens of women I’ve known who started lifting weights—even heavy weights— and in a matter of 4–6 weeks looked more lean, symmetrical and feminine because of their efforts. I can’t think of a single example of a woman who bulked up because of lifting.

I believe that both men and women would derive greater benefit from resistance training exercises if they would crank up the intensity just a bit. Rest assured, you can put aside your fear that starting a lifting program will someday land you on the cover of that bodybuilding  magazine.

True or False: Resistance training can help you lose weight?

Posted on October 11, 2016


Let’s tackle the question of whether engaging in resistance training can help you lose weight.

Many of us have heard fitness professionals say that lifting weights will help you shed pounds. But when you think about it, a natural assumption  might be that lifting weights would cause you to gain weight because you’re strengthening and building muscle.

The truth is that performing resistance-training exercises can indeed help you lose weight. There are a number of reasons why this is the case.

Lifting weights burns calories. The number of calories burned while doing biceps curls, push-ups, squats or resistance-band exercises depends on a number of factors, including the intensity of the lifting session and how many sets and repetitions are performed. On average, we burn from 200– 500 calories an hour lifting weights. If you are lifting 3–4 times a week, those calories can really add up.

Our metabolism elevates slightly when we lift weights. Following our lifting session, our metabolism doesn’t immediately drop to what its baseline level was prior to hitting the gym; it can stay elevated for minutes or even hours afterward.

This phenomenon known as EPOC—excess post-exercise oxygen consumption—results in a slightly increased rate of oxygen update after exercise as the body works to restore hormonal balance and replenish fuel stores. You burn additional calories during this recovery process. The more intense the workout, the longer your metabolism will stay elevated and the more calories you will burn.

Researchers Kirk & Colleagues (2009) examined whether resistance training had an impact on energy expenditure and fat oxidation in men and women. They studied overweight young adults and had them lift weights three days a week for six months, performing one set of nine exercises with 3–6 repetitions. Following the study, the authors concluded that their findings “suggest that a minimal resistance training program may provide a sufficient stimulus to impact daily energy balance and to prevent long-term weight or body fat gain in sedentary, overweight young adults.”

Muscle is metabolically active tissue; each pound of muscle we have burns about 20 calories a day at rest. Considering that after age 30 we lose from 5–10% of our muscle mass per decade, you can see how maintaining the muscle mass we have—or adding to it a bit by resistance training—could help with weight maintenance over our  lifetime.

True or False: More candy is sold for Valentine’s day than any other Holiday?

Posted on September 22, 2016

False.86 candy on valentines

Valentine’s Day, another opportunity for me to forget a “special” occasion for my wife and be riddled with guilt. As if remembering to buy gifts on Christmas, birthdays, Easter, anniversaries, ground hog’s day, mother’s day, and of course helping my kids pull off an April Fools prank isn’t enough! Valentine’s Day, celebrated on February 14th, was established in AD 500 and has traditionally been a day for lovers to display affection for each other by offering gifts of cards, candy, and flowers. It is thought that the designation “Valentine’s Day” came from a Christian martyr or martyrs named Valentine. According to the website of the National Confectioners Association (NCA), one of those men, a priest named Valentine, was beheaded by order of the Roman emperor Claudius II on February 14th 270 AD because he was performing marriage ceremonies, something the emperor had outlawed. The website also says that more than 36 million boxes of heart shaped candy are sold for Valentine’s Day. Another tradition related to Valentine’s Day, in no way connected to lovers, is for children to exchange valentines at school. Our three children usually come home with dozens of valentines, and most of them have heart shaped candy, a sucker, or some form of cavity-causing delicacy attached to them. It’s really no surprise, then, that so many people think more candy is sold for Valentine’s Day than any other holiday. The truth is, however, that Valentine’s Day ranks fourth on the list of holidays for candy purchases. According to sales figures for 2007 compiled by the National Confectioners Association based upon data from Information Resources, Inc., and cited in an article published in Confectioner (2007), the top four selling holidays for candy were Valentine’s Day (1 billion), Christmas (1.4 billion), Easter (1.9 billion) and Halloween (2.1 billion). Trick or treat!

True or False: Certain dogs can smell cancer?

Posted on September 13, 2016


Many people affection89 dogs can smell cancerately refer to dogs as man’s best friend. I’ve grown up with dogs and have always had dogs in my life, so I would wholeheartedly agree with that statement. Dogs provide us with companionship, help seeing-impaired individuals safely navigate streets and sidewalks, and help farmers and ranchers herd sheep and cattle; dogs are also used to locate missing persons and detect things like drugs and bombs (a dog’s sense of smell is estimated to be 10,000 to 100,000 times more sensitive than a human’s). Recently, I had a chance to spend some time with a gentleman (Mike) from England at an outdoor archery range. Mike happened to have epilepsy and always traveled with his dog. I learned that day that Mike’s dog could warn Mike before he was going to have a seizure. Usually the warning (barking) came two to five hours before a seizure occurred, and Mike said his dog was right one hundred percent of the time. I was truly amazed! It now appears that dogs may also start being used to help detect cancer. A study by McCulloch and colleagues (2006) published in the journal Integrative Cancer Therapies examined whether dogs could be trained to detect cancer simply by sniffing someone’s breath. Due to increased oxidative stress, cancer cells emit slightly different waste products than normal cells. The results of the study suggest that dogs can be trained to smell cancer with high degrees of sensitivity and specificity. The authors concluded that “training was efficient and cancer identification was accurate; in a matter of weeks, ordinary household dogs with only basic behavioral ‘puppy training’ were trained to accurately distinguish breath samples of lung and breast cancer patients from those of controls.” The dogs used for the study were Portuguese water dogs and Labrador retrievers, but the ability to be trained to detect cancer is probably not breed specific.

True or False: There is a link between the full moon and bad behavior in humans?

Posted on July 18, 2016


90 moon and behaviorIf I were to base my response to this myth on what occurs in television shows and movies, the answer would be a resounding “yes!” TV shows and movies frequently have werewolves, zombies, and many other undesirables coming out during a full moon to engage in their sinister activities. These media outlets also exaggerate the amount of crime and abnormal human behavior that occurs during a full moon. This idea that the moon triggers a wide variety of deviant behavior in humans has been with us for many years. Consider that lunacy, which means insanity, is derived from the Latin word “luna” for moon. The full moon is frequently associated with or blamed for things like murder and other crimes, alcoholism, epilepsy, arson, natural disasters, suicide, and mental illness. It is also common for people to think that the moon influences things like the weather, fertility, and birthrates. We frequently read about police officers, paramedics, nurses, and physicians believing that crime rates increase and emergency room visits skyrocket during periods of a full moon. However, this belief is not supported by scientific studies. A few of the many studies that have been conducted on this topic have shown a relationship or association between the full moon and bad behavior, but the overwhelming evidence suggests there is no correlation between the two. Rotton and Kelly (1985) reviewed thirty-seven studies on this topic in an article published in the journal Psychological Bulletin and stated, “Although this meta-analysis uncovered a few statistically significant relations between phases of the moon and behavior, it cannot be concluded that people behave any more (or less) strangely during one phase of the moon than another.” Again, most of the studies conducted and published do not support the idea that the full moon influences human behavior in any way whatsoever.

True or False: Cocoa butter eliminates stretch marks?

Posted on April 26, 2016

False.92 cocoa butter prevents stretch marks

Stretch marks (the medical name is striae gravidarum) are those linear scar-looking lines that appear on the skin. They commonly appear on the stomach and breasts but can also appear on the legs and buttocks. They are frequently a dark purple in color and are a source of embarrassment for many. Stretch marks sometimes appear following pregnancy, after large gains in muscle mass in weight lifters and body builders, or other significant weight gains in a relatively short time period. I experienced stretch marks my freshman year in college when I gained fifty pounds after just nine months (unlimited meal plan in the cafeteria). My wife also developed stretch marks following the birth of our first child. Interestingly, both of us were informed by healthcare providers that using cocoa butter would help eliminate stretch marks and would help prevent more stretch marks from occurring in the future. We both tried cocoa butter but didn’t notice any change in the appearance of the marks. After performing a quick internet search I came across many sites that promote the use of cocoa butter for stretch marks, but the claims of what cocoa butter could do were never backed up by scientific evidence. I was able to find one study (Osman, et al. 2008) where researchers randomly assigned pregnant women to a group that received lotion containing cocoa butter and another group of pregnant women to a group that received a placebo lotion that did not contain cocoa butter. The women entered the study during the first trimester of pregnancy and were instructed to apply the lotion until delivery. Following the study there was no difference in the development of stretch marks in the women who used cocoa butter lotion and those who didn’t.  The authors concluded that their findings did not support the use of cocoa butter lotion to prevent stretch marks.

True or False: Having a husband creates seven extra hours of housework a week for women?

Posted on March 31, 2016

True.91 husbands equal housework

It’s true! Having a husband does create an extra seven hours of housework each week for women. I have to admit I’m feeling a tinge of guilt as I sit and write these words. I’ve been scolded so many times for walking through the house with my shoes on that I’m surprised I still have shoes. I’ll also admit to having done the dishes a few times without using soap and throwing light and dark colored clothes together in the same load of laundry with the hope that everything would not turn out pink. Now, my wife cringes if I even get near the sink or the washing machine. I still get to take out the trash, pick up after the dog, and do most of the weeding in the garden, however. A research study directed by economist Frank Stafford at the University of Michigan Institute for Social Research revealed that women sweep, dust, mop, clean, and pick up an average of seven hours more each week because of their husbands. On the other hand, having a wife saves husbands roughly an hour of housework a week. It’s interesting how much research has been done on who does the household chores. It really isn’t as simple as it was sixty or seventy years ago when more women stayed home and the expectation was that they would take care of much of the housework. Today, with many more dual income families, couples have to work together and decide who is going to do the laundry, cleaning, cooking, and tidying up. The study directed by Stafford revealed some interesting trends. Overall, women spend less time doing housework today (seventeen hours a week) compared to 1976 (twenty-six hours a week) whereas men do more than double the housework today (thirteen hours a week) compared to 1976 (six hours a week). The study also revealed that younger single women (in their twenties and thirties) did the least amount of housework a week, about twelve hours, and married women with more than three children did the most, about twenty-eight hours a week.

True or False: Cancer rates have increased dramatically over the past ten years?

Posted on March 23, 2016

False.94 cancer rates dramatically increased

Cancer is a disease whereby cells divide and grow abnormally, often spreading throughout the body and invading other organs and tissues. According to the National Cancer Institute (NCI), there are over one hundred different types of cancers with the main categories being 1) carcinoma, 2) sarcoma, 3) leukemia, 4) lymphoma and myeloma, and 5) central nervous system cancers. Most people know someone who has battled or is currently battling cancer. It is not surprising that most people mistakenly believe that cancer rates are on the rise, but just the opposite is true. The National Cancer Institute’s Cancer Trends Progress Report for 2009/2010 reveals that death rates for lung, breast, prostate, and colorectal cancers, the four cancers that occur the most frequently, are on the decline. In fact, death rates for all cancers combined continue to go down. The report indicates that the number of people getting cancer has continued to go down since about 2000. Historically speaking, the incidence of cancer increased from the mid 1970’s to about 1990, then leveled off for the next ten years or so, and has been on the decline since. It is important to note that rates for some cancers are on the rise. Those would include esophagus, pancreas, liver, bile duct, testis, kidney, leukemia, thyroid, melanoma of the skin, and childhood cancer. Cancer is the second leading cause of death in the United States; heart disease is the first. The Centers for Disease Control and Prevention reported that in 2007, 616,067 people died of heart disease and 562,875 people died of cancer. The NCI report also stated that blacks had the highest rate of new cancers, followed by whites, with lower rates for Hispanics and Asians. If you want to try and reduce your risk of getting cancer, avoid smoking, eat a healthy balanced diet, engage in regular physical activity, and maintain a normal weight.

True or False: People who drive red cars get pulled over more often?

Posted on March 1, 2016

88 red cars get pulled over more often False.

Every time my wife and I contemplate buying a different vehicle, we spend a lot of time walking around car dealerships and examining our many options. The first thing I usually notice when looking for a new car is the price tag. My reaction is often one of sheer horror—followed by disbelief—and this question: can that really be the correct price for this vehicle? Shortly after the sticker shock wears off, I take a good look at the color and ask myself: is this a color I can tolerate for the next five or even ten years? Inevitably, we come to a shiny red car and I have to sit in it, just for fun. I’ve always believed the old saying that red cars get pulled over more often for speeding. Just sitting idly in the showroom, they look fast. It turns out that there has not been a lot of research examining whether the color of vehicles impacts the frequency at which the drivers of those vehicles get stopped and/or ticketed. However, the little research that is available suggests that this is just an old wives’ tale or urban legend. Newman and Willis (1993) conducted the only published study I could find looking at car color and the chance of getting a speeding ticket. These authors monitored speeding tickets over a twenty-two month period and compared the frequency of tickets by car color to the frequency of cars on the road with those colors. They found that red cars get ticketed about the same amount as gray and brown cars. About ninety-five percent of the tickets in this study were the result of using radar, and many times when radar is used the speed is already obtained before an officer notices the color of the car. Some think that red cars give the appearance of going faster; there really is no good scientific evidence for this either. So go ahead and buy the bright shiny red car without fear of being pulled over and ticketed more often.

True or False: “Only” children are more selfish, bossy, and spoiled?

Posted on February 11, 2016

Fasle.87 only children are spoiled

It is a common misconception that only children (sometimes referred to as “onlies”) are spoiled, selfish, and rotten little brats. To most people it makes perfect sense, and it may even be somewhat logical. When parents have only one child, that child gets all the attention, all the toys, all the affection, and all the coolest birthday presents; they don’t even have any competition selecting which cartoons they are going to watch on Saturday morning. How could they not be self-centered? There has been tremendous growth in the number of single child family units in the past five to ten years. There has also been a fair amount of research looking into whether only children are indeed spoiled and selfish compared to other children with siblings. It appears that they are not. Mancillas (2006) published a very good review article on the topic in the Journal of Counseling and Development stating, “There is clearly a need to correct the negative bias and stereotypes about only children, not only to benefit children and families but to ensure that mental health professionals, researchers, educators, and policy makers articulate an accurate understanding of only children and their families ….” Many children are spoiled and bossy at various times in their lives. I’m a father of three children, and I have to say that it has been my experience that every child (at least mine—and all my friends’ children) at some point thinks everything should revolve around them. This commonly happens in a child’s early years, but I’ve also heard that this can be the case during the teenage years as well, as shocking as that may sound. Everything I’ve ever read and been taught suggests that how a child acts and behaves is much more a result of parenting style than number of siblings or birth order.
