Three Tips for Breathing Effectively While Running
As a student at the University of Oregon, Middlesex High School graduate Matthew “Matt” Kafker is taking courses in linguistics, literature, electromagnetic physics, mathematics, and computer science. When not studying, Matt Kafker enjoys staying active by running.
Learning how to breathe properly while running has positive benefits, such as helping to prevent injuries and improving performance. The following are three helpful tips for breathing effectively while running.
1. Breathe from your diaphragm. Breathing from the diaphragm, also referred to as belly breathing, enables maximal oxygen uptake since the lungs can expand fully. Increasing oxygen intake while running enables the muscles to work more efficiently for longer, and also improves mental focus.
2. Take in air through both the nose and mouth. Breathing through both the nose and mouth facilitates maximal oxygen intake. Breathing this way also helps runners to exhale carbon dioxide rapidly, and helps them to keep their rate of breathing steady.
3. Match your breathing with your cadence. Time your breathing so that you are inhaling and exhaling while taking steps on each side of the body, rather than breathing only while steps are being taken on one side of the body Adopting a breathing method that alternates from one side of the body to the other helps to prevent injuries.

Intelligence Quotient - A Flawed Construct
In addition to studying mathematics, Matthew “Matt” Kafker is well-read and has explored a wide range of authors and subjects. A university student, Matt Kafker is reading the works of essayist and author Nassim Nicholas Taleb, such as Incerto.
Mr. Taleb is known for writing essays that cover topics focusing on randomness, probability, and uncertainty. In an essay published last year, the essayist argues that IQ is, for the most part, a “pseudoscience fraud.” The author’s paper includes some of the other criticisms of traditional IQ tests, but he also refutes the mathematical construct on which intelligence tests are supported.
The author suggests that these intelligence tests have the potential to determine more than smartness. When looking at other exams, those who have not scored well on IQ tests typically would score poorly on college entrance exams, simply because many of these exams are based on IQ tests, which suggests there is bias in most standardized testing.
The author also addresses the weaknesses in the statistical model from which it draws its conclusions. The author questions the validity of the test because co-variance between IQ and performance is un-informational, or it simply does not exist. The figures support a finite number in a sample that does not exist, and this can lead to overestimating the prediction.
Another flaw relates to the way standard deviation is used to explain probability, and he mentions this in terms of the way IQ has been used to define race. Mr. Taleb argues that richer models have to be developed because different groups require different variances and skewness. These tests have to take into consideration nuances across cultures and groups.
