Why You Should Play a Sport You Really Suck At

So when life hands me an opportunity to check my daily fitness box without swiping my key tag, I take it. 


Mow a lawn? That’s a workout. Partake in a three-legged race? That counts, too. Complete a spirited pub crawl? Depending on the mileage, it might even get me off the hook for tomorrow’s sweat session.  


You know what else you can add to the list? Broomball.


Don’t worry if you’ve never heard of the sport. I hadn’t either, but when NBC recently invited me to try it out on an episode of 1st Look, I jumped at the chance. 


Broomball is silly, but simple: You run around wearing tennis shoes on ice, flailing clumsily and swatting at a ball with a plastic paddle that sort of looks like a broom. 


It’s a lot like hockey, but with twice as many wipeouts. See for yourself: 


An hour into my first broomball game, I was sweating so much that steam was rising off of my body. The next day, my glutes and obliques were wrecked, as were the muscles supporting my lower back.


The aches were so glorious, I realized I should be trying more new sports I know nothing about—and so should you. Here’s why:  


1. You’ll grow muscle faster.


It’s not that broomball is a more efficient workout than CrossFit. It has the advantage of putting you off balance, sure. But so do surfing, skateboarding, and those stupid hoverboard things. 


I was sore simply because I was doing something new.

“Whenever you try a new sport or exercise, you stress your muscles in a way that they are not used to,” says Joel Martin, Ph.D., an assistant professor of kinesiology at George Mason University.


You’re not just engaging different body parts—your muscles are physically contracting in unique ways. You’re also moving at different speeds and directions to meet the demands of the sport. 


As you improve, your muscles will adapt. That’s good if your goal is to impress women with your superior athleticism. But if you’re trying to improve your fitness, adaptation actually undermines your progress. 


“If your main reason for playing a sport is to get in shape, you almost want to avoid becoming too proficient,” says Martin. Once your muscles learn to keep up, you begin burning fewer calories with each new match. 


2. You’ll build brainpower.


Do you remember the first time you played volleyball? Odds are you embarrassed yourself. Every ball that came to you ended up in the net or out of bounds. 


But your humiliation wasn’t a waste: You were nurturing new brain cells. In one study, researchers scanned the brains of 40 people, then asked them to practice learning a new motor skill for 30 minutes a day, 5 days a week. 


In this case, the subjects were learning to juggle. After six weeks of training and a 4-week wash-out period, the researchers looked at the participants’ brains once again. Grey matter in their dorsal parietal and primary motor cortexes was measurably thicker.

By the end of the study, people with the most grey matter at the start also turned out to be the best jugglers. It’s a reinforcing loop: Grey matter helps you learn motor skills faster, and learning motor skills helps you build more grey matter. 


So the more time you spend learning tennis, skateboarding, and air hockey, the quicker you’ll pick up seemingly unrelated activities, like soccer, snowboarding, and fly fishing.  


3. You’ll break out of a fitness funk.  


There’s no reason you should dread your workouts. You should look forward to them, and you should notice appreciable gains. 


If you’re not excited to break a sweat, you may just need some novelty. 


“Way too many people go to the gym and do the same routine over and over for years,” says Martin. “It’s more effective to make systematic changes to your workout routine.”


These changes, Martin says, can be quantitative or qualitative: You can add more reps or weight to your old routine (that’s a quantitative change), or opt for a complete workout overhaul (a qualitative change). 


“Many college strength and conditioning coaches will program 4-to 6-week blocks to focus on different aspects of fitness: strength, power, hypertrophy, endurance, and so on,” he says. That’s how their athletes avoid fitness plateaus.

Think about that. What if, after every 4 to 6 weeks in the gym, you took a 4- to 6-week hiatus to focus on a new sport?  


It could be rock climbing, ultimate Frisbee, or even broomball. Doesn’t matter. You’d likely stay motivated, and overall, you’d be more fit. 


The only downside is that you have to be the guy who doesn’t know what he’s doing. Think you can handle that?

Can cooling clothes really burn fat? Thin Ice's claims crackle under weight

People struggling with their weight make easy targets for scams. Fat-busting pills, fad diets, and workout gadgets come and go as their popularity is overwhelmed by their ineffectiveness. Now a line of clothing purportedly tricks your body into losing weight by “hacking your metabolism” — but are the only hacks here those selling the phony technology?



“This would be too uncomfortable to tolerate for the many, many months of wearing Thin Ice that would be required to produce any significant weight loss.”



The Thin Ice Weight Loss Clothing Line, recently backed on Indiegogo by more than half a million dollars, is designed to trick your body into thinking you’re cold and burning fat to keep you warm. The team behind Thin Ice is kicking off the line with two items to target areas of your body with a lot of thermoreceptors (nerves that detect temperature changes). The first is a tank top, dubbed a “vest.” The second is a pair of insoles. Peltier cooling strips (used to cool compact electronics) and the rechargeable battery that powers them are built in. Both garments connect to the Thin Ice Android or iOS app using Bluetooth Low Energy so you can see how many calories you’ve burned and control the temperature.


Turn the temp down and watch the weight fall off, the company claims.


And don’t worry, you won’t freeze to death: Even if you turn the temp as low as it will go, the company says you won’t end up shivering. The cooling mechanism targets specific parts of your body to trick your nervous system and avoid triggering the shiver response. The science is explained in depth in Scientific American and the New England Journal of Medicineamong others. In short, cold triggers your brown adipose tissue (BAT) to consume lipids (A.K.A. fat) to produce heat, and Thin Ice is designed to affect that consumption without chilling you enough to cause muscle spasms (shivering).


Weight-loss facts and figures


It all sounds very clever, as does Adam Paulin, the creator of Thin Ice Clothing — an NCAA athlete who holds degrees in neurology and psychology from the University of Toronto. But is it real? One backer questioned Adam, asserting on the company’s Indiegogo page that research says the temperature range required for thermogenesis — the process of internal heat production that burns fat — is lower than what the clothes can achieve. Adam’s response was simply to assert there were studies saying the opposite. (Paulin did not respond to multiple emails from Digital Trends.)


That’s the thing about emerging technologies: If you want to be an early adopter, it helps to do your own research. Some backers may have not have read the New England Journal of Medicine study listed on Thin Ice’s Indiegogo page thoroughly enough. Consider the statement of conclusion in that paper, which notes that “mean brown-adipose-tissue activity was significantly lower in the overweight or obese subjects than in the lean subjects.” This means that the heavier you are, the less effective cold therapy may be for you.


Thin-Ice-Weight-Loss-002


Digital Trends reached out to Shaun Morrison, a member of the Department of Neurological Surgery at Oregon Health and Science University for his thoughts. Morrison was skeptical, to say the least. “The BAT in overweight and obese humans cannot be activated by cooling,” he wrote to us. “Thus, the ThinIce approach is not expected to activate the BAT in overweight people and thus isn’t expected to produce weight loss in overweight people.”


Dr. Morrison would know. He’s currently running a study on central inhibitory regulation of brown adipose thermogenesis, and has studied the central regulation of sympathetic activity to brown fat in previous work. While he said there was hope for people with a normal body mass index, he pointed out that over time even their Thin Ice results might suffer.


“Although skin blood flow should be reduced in the areas of the Thin Ice stimulation, the normal level of heat production from the basic metabolic processes in the body of an adult human could produce a subcutaneous temperature that would counteract a mild cooling from the ThinIce outside the skin, resulting in little stimulation of cool thermoreceptors, and little activation of BAT.” After a while, the body would simply adjust to counteract mild external cooling.



“This phenomenon could require that the ThinIce product must produce a greater level of skin cooling to get BAT activation, and, at some point, this would be too uncomfortable to tolerate for the many, many months of wearing Thin Ice that would be required to produce any significant weight loss.”


Maybe some backers did read the studies attached to the Indiegogo page and are aware that no one can lose weight with cold alone. To be fair, the Thin Ice app also suggests meals and workouts to “supercharge” weight loss. However, Dr. Morrison went on to point out that over time wearing cooling clothes might change your metabolism, making you feel hungrier.


Related: New smart clothes will be able to adjust to your mood


“I would be concerned that if BAT were continuously activated (even at some low level) and energy stored in fat were consumed by BAT to produce heat, the brain circuits regulating metabolism would sense this sustained energy consumption and attempt to reinstate the energy stores in fat by increasing food consumption, thereby eliminating any weight loss effect of the BAT activation.” So Thin Ice might turn the little rumble in a dieter’s stomach into a gnawing gurgle of emptiness.


Coming soon to a store near you?


On the other hand, maybe backers haven’t really paid attention at all. Based on funding alone, it appears backers are all in, regardless of Thin Ice’s actual effectiveness. The Thin Ice Weight Loss campaign was 3,786 percent funded as of September 17. People grabbed shirts and insoles for $100, saving 35 percent off the projected retail. Who wouldn’t want a shortcut to weight loss? Besides, some people readily spend this amount on workout gear, so it’s not a totally ridiculous ask for a smart shirt that connects to an app.


Unfortunately, there are limitations on this gear you don’t normally see on garment tag. For instance, you can’t run Think Ice through the washer (the company recommends using antibiotic wipes for regular cleanings). And the insoles aren’t for high-impact activities like running or basketball, but more to keep you cool during your daily errands.


It’s possible consumers wearing those insoles won’t be the only ones with cold feet. The company just missed its December shipping deadline, which is still listed on the Indiegogo site. An update on the site explains: “In our last email update in November, we told you that we were looking forward to shipping your Thin Ice weight loss product in the spring. We are happy and excited to tell you that we remain on target.”


Will it ship in the Spring? Like a foodie after Thanksgiving, the wait is still on.

7 Misconceptions About Going To The Gynecologist, Because It's Really Not As Bad As You Think

There’s a new viral video making the rounds about a woman with two vaginas. While it’s fascinating, it’s also cringe-worthy in that the video’s star, Cassandra Bankson, has some incorrect information about how to care for her twin cervixes. In particular, she replied to a question about whether or not she needed two pap tests by replying that she didn’t know if she was old enough to need that screening test yet. No judgement here — but this is incorrect information. And a common misconception. A lot of women don’t know if and when they need to see their gynecologists to get these potentially life-saving screening tests. 


And I get it. No one wants to go to the gynecologist. It’s up there with going to the dentist or spending a night in jail. So it’s no wonder our cultural conversation about it includes a lot of invalid excuses to skip the stirrups. But skipping them does more harm that you might think. The CDC reports over a million cases of chlamydia alone, the most common STI among millennial-aged women, with at least that many estimated cases going undiagnosed or unreported. And that’s just one type of STI. So making excuses to avoid the doctor equates to rolling the dice with your health and your future fertility. Here are seven more busted excuses and myths about going to the gynecologist. 


1. Going to the gynecologist is THE WORST


I mean, it’s not really fun, but going to the gynecologist is not so terrible that you need to stress about it. For the most part, it’s in and out in under 20 minutes, and more than half of that is talk. The exam may be uncomfortable for a moment, but it usually doesn’t hurt and you can ask your doctor to walk you through it. The worst part of the exam is often the anticipation, so don’t psych yourself out! 


2. I don’t have to go because I’m not old enough yet


The American Congress of Obstetricians and Gynecologists recommends that young women begin seeing the gynecologist between the ages of 13 and 15. There’s so much more to going to the gyno than just getting a vaginal exam. Your doctor can teach you about your body and answer questions you may be too embarrassed to ask family and friends. She can also talk to you about birth control, periods, emotional health, breast health, acne, sex, pregnancy options, and even relationships. 



3. I don’t have to go because I’m not sexually active









Sex is a big part of reproductive health, but it’s not the only part. As a young teen, your gyno will get a sense of what’s normal for your body, setting a baseline to identify potential future problems more easily. Also, people define “sexually active” in different ways, and there are some behaviors you might not call “sex” but that still pose risk factors for sexually transmitted infections. 



4. If I had a problem/STD, I’d know by now


This is a common but dangerous line of thinking. So many sexually transmitted infections have no symptoms, or easy-to-miss symptoms. If ignored, those infections can lead to serious problems, such as pelvic inflammatory disease, fertility problems and even some cancers. The good news is, most STI tests and treatments are no big deal if you take care of things before they get serious. 


5. I can’t afford it


The Affordable Care Act made many types of preventative care free. Check with your insurance provider for the details. And if you don’t have insurance or can’t afford your co-pays, health centers such as Planned Parenthood often offer low-cost or sliding-fee-scale services. 


6. I’m a lesbian


You’re a lesbian? Me too! And I still have breasts and a vagina and hormones that still need to be healthy. Regardless of your sexual orientation or gender identity, you still need to keep your sexual and reproductive health in check. In fact, lesbians are both less likely to use protection during sex and less likely to get cervical cancer screenings. And no matter how much of a vagina expert your partner may be, she doesn’t count unless she’s been to vagina medical school. 


7. I already had my pap this year


New guidelines mean you may only need a pap test or vaginal exam every three years. That doesn’t mean you should only see your gyno every three years. In between pap tests, you can (and should) still get screened for sexually transmitted infection, breast changes, and overall sexual health. You can also check in about birth control.

Edinburgh Community Food on why fibre really is good for you!

Print Friendly

By Nicola Murray (Student-on-Placement at ECF, Abertay University)


So, what is the big deal about dietary fibre? Is it just to keep us regular? In a word, no – it does so much more!


Fibre is an important part of a healthy balanced diet and has many benefits for our overall health. It can improve not only our digestive health – think constipation, bowel cancer or diverticular disease – but can help reduce the risk of heart disease, strokes, diabetes and some others cancers too. High fibre foods keep us feeling fuller for longer by slowing down digestion. This can help us maintain a healthy weight as we are less likely to reach for a high sugar mid-morning snack.


In the UK, the average person consumes around 14g of fibre per day which is much lower than the recommend 18g. Fibre is a complex carbohydrate found only in plant foods. Foods such as meat, fish, and dairy don’t contain any at all. Simple carbohydrates (like sugars) are broken down to provide fuel but dietary fibre has other important roles in the body. While we gain few nutrients or energy from fibre its passage through our digestive system helps remove potentially harmful waste from the body. Moreover, some types of fibre are actually fermented in the lower intestine, producing some important nutrients like vitamin K (which helps our blood clot), B12 (for processing energy) and fatty acids (which are great for our hearts).


There are two different type of fibre: soluble and insoluble. Soluble fibre – found in fruits, vegetables, grains, beans and pulses – can be digested by our bodies as it is dissolved in water and forms a gel in the gut. It is then passed through the GI tract, absorbing water and slowing down our digestion. What this does is help keep stool soft – making it easier to pass – which can prevent or treat constipation.


Insoluble fibre – found in whole grains, vegetables, high fibre cereals, nuts and seeds – cannot be digested by the body. It passes through our gut without being broken down and helps other foods move through our digestive system more easily. This keeps our bowels healthy and helps prevent digestive problems. If suffering from diarrhoea we should limit the amount of soluble fibre we are consuming and increase the insoluble fibres. On the other hand, if suffering from constipation we should increase soluble fibre (e.g. fruit and veg) and reduce the insoluble type.


Box-out – health benefits of fibre
• Keeps us regular
• Helps reduce cholesterol
• Lowers risk of heart disease, strokes and diabetes
• Assists in removing waste from the body
• May help lower blood pressure
• Keeps us fuller for longer, helping us to maintain a healthy weight
• Produces vitamins K and B12, plus healthy fatty acids in the colon
• Provides food for healthy gut bacteria
• Helps relieve diarrhoea, constipation and haemorrhoids


To increase the amount of fibre in our diets try to incorporate fibre into every meal – aim for 2 portions.


Top tips for increasing your fibre
• Swap white bread, rice and pasta for tastier wholemeal alternatives
• Eat more oat-based foods such as no-added-sugar porridge, muesli or oatcakes
• Try to incorporate fibre into every meal – aim for 2 portions per meal
• Go for whole fruit rather than fruit juice
• Go for more highly nutritious and high fibre lentils, beans and other pulses
• Try going ‘veggie’ a few days a week
• Increase your fibre intake fibre slowly to reduce the risk of bloating and stomach cramps
• Drink plenty of water to help the passage of the fibre in the gut
