Exercise Can Help Your Social Life

When discussing the benefits of fitness, we usually focus on the physical side of things. However, there are additional social and psychological benefits that are often overlooked. Astudy this month in the International Journal of Behavioral Nutrition and Physical Activity shed some light on the psychosocial aspects of fitness.

Since there is so much important information out there about the physical effects of exercise and its importance in reducing disease, the U.S. Department of Health and Human Services produces guidelines for the public. While most serious athletes will exceed the standard guidelines for good physical health, we don't know if the same could be said for optimal mental health.

When determining what guidelines to recommend for good physical health, the Department of Health and Human Services depends on the relationships found in science. When it comes tomental health, however, there simply isn’t enough information out there to be able to make the same recommendations. In fact, the Department of Health and Human Services noted in their2008 guidelines that “insufficient evidence precludes conclusions about the minimal or optimal types or amounts of physical activity for mental health.”

In the latest study, the researchers were looking to compile the existing information on howphysical activity affects mental health. They determined that a meta-analysis, or a study that examines other studies, was necessary. Reviews like this one are often used to recommend future research as well as provide answers.

The first thing the research team did was address the suspicion laid out in the official guidelines. They identified 3,668 studies as candidates for their review, but only eleven studies met their criteria. The researchers were interested specifically in team sports to emphasize the social aspect of human psychological heath. While this factor eliminated many of the studies that only examined individual exercise, that’s still a scant few considering they looked at over 22 years worth of studies.

Despite the small number of studies, they all agreed that there are both psychological and social benefits from exercise. The most common benefits found were feelings of wellbeing and less stress. Unsurprisingly, team sports were better at creating social health, as well as psychological health in general. Interestingly, the differences between solo and team sports in health outcomes weren’t because teamwork resulted in more vigorous or more frequent exercise, but were purely a result of increased socialization.

While the results of this study aren’t shocking, they reinforce our beliefs and may even motivate some readers to go out and take up a sport. The researchers advise picking a sport that you find to be the most fun, which actually yields the greatest health benefits, even if you choose a solo sport. In other words, having the most fun will make you the healthiest.

ENGLISH GRAMMAR TEST


This short English grammar test will tell you if you're level A, B or C on the CEFR scale for receptive English skills (listening and reading). Although I didn't build it, I haven't found a more accurate English grammar test anywhere, at least not for free. There's a longer version of this same English grammar test that gives you a more precise score and you can publish that score straight to your LinkedIn profile if you want to. If you're really looking for a challenge, there's a 2 hour version which tells you what you'd score on the TOEFL and IELTS if you took those tests. All three English grammar tests are available at no charge over on the site of the test's makers.

When you're looking for an English grammar test, it's better to choose a test that evaluates English grammar usage, that is to say, English in context, rather than just testing rules. Memorizing English grammar rules and being able to recite them on command doesn't necessarily lead to mastery of English. That's what I like so much about this particular suite of English grammar tests, as compared to others I've tried. They test English in context, making sure you can use grammar rules, while also checking that you have enough vocabulary to understand everyday English. Free is also nice.

RELATIVE CLAUSES

Relative clauses are non-essential parts of a sentence. They may add meaning, but if they are removed, the sentence will still function grammatically. There are two broad types of relative clauses in English. It is important to distinguish between them because it affects the choice of pronoun used to introduce the clause. There is a more detailed page about preposition placement in relative clauses.

DEFINING CLAUSES

defining or identifying clause tells us which specific person or thing we are talking about in a larger group of people or things. If a defining relative clause is removed, the meaning of the sentence changes significantly. A defining relative clause is not separated from the rest of the sentence by commas or parentheses.
EXAMPLES
  • The woman who visited me in the hospital was very kind.
  • The umbrella that I bought last week is already broken.
  • The man who stole my backpack has been arrested.
  • The weather that we had this summer was beautiful.
Learn more about using defining relative clauses correctly.

NON-DEFINING CLAUSES

non-defining or non-essential clause gives us more information about the person or thing we are talking about. If a non-defining relative clause is removed from a sentence, we lose some detail, but the overall meaning of the sentence remains the same. Non-defining relative clauses are always set off from the rest of the sentence with commas or parentheses.
EXAMPLES
  • The farmer, whose name was Fred, sold us 10 pounds of potatoes.
  • Elephants, which are the largest land mammals, live in herds of 10 or more adults.
  • The author, who graduated from the same university I did, gave a wonderful presentation.
  • My mother, who is 86, lives in Paris.

PUNCTUATION

Punctuation is used to create sense, clarity and stress in sentences. You use punctuation marks to structure and organise your writing.
You can quickly see why punctuation is important if you try and read this sentence which has no punctuation at all:
perhaps you dont always need to use commas periods colons etc to make sentences clear when i am in a hurry tired cold lazy or angry i sometimes leave out punctuation marks grammar is stupid i can write without it and dont need it my uncle Harry once said he was not very clever and i never understood a word he wrote to me i think ill learn some punctuation not too much enough to write to Uncle Harry he needs some help
Now let's see if punctuating it makes a difference!
Perhaps you don't always need to use commas, periods, colons etc. to make sentences clear. When I am in a hurry, tired, cold, lazy, or angry I sometimes leave out punctuation marks. "Grammar is stupid! I can write without it and don't need it," my uncle Harry once said. He was not very clever, and I never understood a word he wrote to me. I think I'll learn some punctuation - not too much, enough to write to Uncle Harry. He needs some help!

We continue our topic. Let's learn today about adverbs.

ADVERBS

Adverbs are a very broad collection of words that may describe how, where, or when an action took place. They may also express the viewpoint of the speaker about the action, the intensity of an adjective or another adverb, or several other functions. Use these pages about the grammar of adverbs in English to become more precise and more descriptive in your speaking and writing.
