There are three main types of stretching that the general layman will be familiar with. There are a couple of others, but they are extreme techniques, and generally not used by the everyday athlete. Ballistic - The "lean and bounce" method, where you repeatedly bob back and forth in the stretch Dynamic - Mimics the motion of the activity in increasing ...

The general consensus on the internet and among various physical trainers is that static stretching in 20-30 second segments is sufficient to increase range of motion (ROM) in a muscle. This is corroborated by two studies (Very similar in nature, conducted by the same people), where one study showed that there was no difference when time was increased from ...

There are many factors that influence the transmission of infectious agents, and in the case of public swimming pools: the number of bathers the condition of the pool care taken to disinfect the water ...will heavily influence the likelihood of contracting a disease.

Judging from your description, you're most probably doing everything correctly. But ok, if you wanted to be absolutely sure, you really would have to precisely measure your calorie intake vs calorie expenditure (with a tool like cronometer or sth). And as far as gaining 100 grams in 2 days goes, that's just jumping to conclusions and easily falls within ...

In most cases, swimming is good exercise. Light swimming is also a therapy for people with joint and back pain. The breaststroke is not usually the recommended stroke for therapy because, if done incorrectly, it can be harmful. Because you have to keep bringing your head up to breath, the joints in your upper back and neck get extended, and have to deal ...

Although stretching is not the only answer, you should certainly do some pre-exercising. In a state of inaction, your muscles contract and tighten, and also lose heat. This makes them brittle and inert. Going straight into heavy exercise can cause significant damage, and so in going from inactive to fully active, you should ideally 'warm-up' with a more ...

The long and short of it is that the novel coronavirus can be experimentally aerosolized where it can persist in the air for several hours but a number of studies have failed to detect virus in samples taken from the air of the rooms of patients with active disease.

This all falls to a matter of degree - most importantly mechanism of injury. I'll explain the physics in allegorical terms first and then explain as it relates to medicine. The mechanism refers to the amount of force experienced in the injury process which allows us to predict injury patterns. For example: A motor vehicle collision at highway speed has a ...

It looks they are relevant according to these two researches: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4538725/ Results: Both soccer players and controls had genu varum. However, the incidence of genu varum was higher in the soccer players (P = 0.0001) and it was more prevalent in the 16-18 year age group (P = 0.0001). The results revealed ...

Your question focuses on the location of the receptors (the part of the nociceptors that is reacting to mechanical, thermal, or chemical stimuli). An equally important part of a nociceptor is the axon, or nerve fibre, that conducts the action potential from the muscle or tendon (to go with your example) all the way to the spinal cord from where it makes ...

That will be hard to predict, as it varies from person to person. I've had one of them extracted and could train the next day (a different sport, korfball, but with similar impact on your body as badminton); a team mate couldn't play for a week after his operation. Wikipedia states Most patients will experience pain and swelling (worst on the first post-...
