TL,DR: it's in the right ballpark (but depends on how much you weigh, what you're carrying, how fast you're going, etc.).
For the elevation alone (not counting the extra energy spent moving your legs), the energy cost to climb a height h is m * g * h where m is your mass and g ≈ 9.81 m/s2 is the gravitational acceleration. For a mass of 70 kg (≈ 11 stone, ...
taking away your stress
exercise is proven to increase concentrations of norepinephrine, a chemical that can moderate the brain’s response to stress.
and boosting happy chemicals
usually within five minutes after moderate exercise you get a mood-enhancement effect.

data suggests that active people are less ...
This is a tough question to answer as there are a lot of ifs and buts.
Weight loss is all about caloric deficit, expend more energy than you consume and you lose weight. Most people do this by dieting, but the body tends to readjust the resting metabolic rate so that you don't lose too much reserves. Thus exercise plus diet is needed for weight loss to be ...
The 'mgh' analysis given by @Gilles is correct but for a consideration of muscle efficiency - the ratio of useful mechanical work (energy) output to biochemical energy input for human muscle. This is often quoted as being around 18-26% e.g. as referenced here https://en.wikipedia.org/wiki/Bicycle_performance. So yes, to get the kCal. burned you would have to ...

There is a demonstrated link in the literature between both cumulative compressive loads of the spine and low duration, high peak compression with low back pain incidence and spondylosis.
All types of sit-ups result in high levels of peak compression which meets the threshold of peak compression levels studied within the literature.

It is not that our body "focuses" on alcohol but alcohol being a liquid gets absorbed and metabolized quickly (or first in relation to your question), whereas food needs to be broken down first into pieces by our teeth, then it mixes with saliva and then undergoes digestion in stomach and this process of breaking down of solid food to small absorbable ...
About 100 a year in the USA.
An estimated 195 100 individuals (95% confidence interval, 140 400-249 800) were treated in US EDs for snow shovel–related incidents during the 17-year study period, averaging 11 500 individuals annually (SD, 5300). The average annual rate of snow shovel–related injuries and medical emergencies was 4.15 per 100 000 population. ...
There is good evidence that exercise improves symptoms in people suffering from anxiety and depression. There isn't enough evidence available yet to make the case for exercise improving mood more generally.

The research literature suggests that for many variables there is now ample evidence that a ...
This answer looks at the results of three different meta-analyses that look at HIT vs traditional endurance training. The evidence is mixed, but generally supports HIT being slightly better.

The second paper in the question concludes that High Intensity Interval Training (HIIT) for teenagers is better for cardio than not ...
There are basically 2 parts to this:
How Many Calories Are In a Big Mac®?
The number of calories in a Big Mac® varies by country, but the figure given of 540 calories is accurate for a US Big Mac®.
How Many Calories Does Running Burn?
The number of calories burnt per minute when running depends on how much you weigh and how fast you run. The following ...
Yes, for example it makes you slimmer
A 10,000 steps·d−1 exercise prescription resulted in weight loss over 36 weeks in previously sedentary, overweight/obese adults. Adherence to the step goal had a marked effect on the outcome.

No. Using a tracker does not make you fatter, and that is not what this study claims.
Lets start with the participants:
Among young adults with a BMI between 25 and less than 40
(so no already fit people here).
And this important little note:
If weight loss exceeded 6% during each 4-week period or if BMI was 22 or less, prescribed individual ...
Yes, and my arguments for saying so are two-fold.
First, there's the historical timeline:
When she first arrived there was jubilation
Then some skeptics questioned the feat, their principal argument being a sudden increase in her speed overnight
However an independent oceanographer concurred with that speed's being due to an unusual, favourable ocean ...
The contrary is in part true, in that running barefoot rather than wearing shoes with thick padding and cushioning tends to decrease injury and strengthen the foot and leg muscles.
The running shoe itself has also been examined as a possible cause of many injuries associated with shod running. One 1991 study ...
It is evident that muscle growth happens through exercise. This article, Muscle growth and exercise explains that there are three mechanisms involved:
by an increase in muscle cell numbers,
by an increase in muscle fiber diameter, and
by an increase in fiber length.
So, your question is whether the first mechanism is affected by exercise. ...
Sauna makes your heart work harder
Sauna definitely increases heart rate ( and )

Bottom-line: colder ambient temperature does allow you to burn more calories. Whether you actually do it, is another question. E.g. in cold conditions, you may not excercise at maximum power for fear of getting really cold if you have to stop for some reason when moist of sweat.
Please note that it is not completely clear what "the same exercise" is:
You're asking a lot of questions and they aren't as specific as they probably should be for a site like this. Let me just cut to the chase, and then try to justify my answers.

Many of the low volume or high intensity styled programs make claims about diminishing returns from extra work. The easiest way to address this question is to look at the science of training volume. I agree with one of the commenter's (Dave) that exercise science is not always a solid science, but his recommendation replaces measurement with opinion.
EMS is also called as Neuromuscular Electrical Stimulation (NMES) or “electromyostimulation". Muscles which perform different tasks, in addition to having different muscle architecture, respond to different electrical input. For example, skeletal muscles that play a postural role, and thus have a high proportion of slow fibers, are physiologically activated ...
Based on the book "The Brain That Changes Itself" not the exercise itself, but the learning
of new exercise, dance, activity, etc. is making your brain build new neuronal connection and even creates new neurons.
It' not repeating of the same exercise, but learning of new ones makes you "smarter".
This theory, that novel environments may trigger ...
Is the claim true that excessive running as mentioned, can be damaging to the myocardium and coronary arteries?
The anecdotal article you read refers to a Mayo Clinic article whose abstract is

a walk after my lunch [is] a healthy habit that helps with digestion.
Walking may be a healthy habit but it does not specifically assist digestion.
Digestion is a process which takes place in resting conditions. Exercise is characterised by a shift in blood flow away from the gastrointestinal (GI) tract towards the active muscle and the lungs.

There's lots of research into this, and it's not that simple.
In fact, there is even research into how people overestimate how simple it is!
Much of the research into the illiptical machine read-outs is aimed at improving the models, so they are more accurate, (or, as we see below, selecting the best models, so they are the ones you see in gyms) so we ...
This claim is often repeated on lifting forums and among people at the gym. "Cardio kills gains!" is even a running joke, to be found in fitness humour forums like www.reddit.com/r/swoleacceptance. The scientific answer appears to be sort of.
Originally I had a nice list of sources (there's a very large literature on this topic), but by far the best is an ...
Here is a 2008 article in the New York Times, referencing an article published in Nature. According to this research, fat cells die as part of normal body processes, but they are replaced in the same quantities. This appears to maintain the same number of fat cells in the body, under most circumstances.
