What Is Biomechanics in the Study of Biophysics?

Biomechanics, which is the study of the interaction of biological organisms with their surroundings, is an important area of biophysics. A solid understanding of biomechanics is important for people interested [more…]

Study of Fluids in Biophysics

Gasses and liquids are considered fluids. If you have ever watched smoke rise from a fire or a stick float down the river, you can see the way the fluid moves can be very complicated. The good news is [more…]

How Biophysics Relates to Sound Waves

The ability of people to produce and hear sound is a very important part of everyday lives. Biophysics tells you what the properties of waves are, and it tells you that [more…]

Avoiding Common Errors in Your Biophysics Course

You, like many students, may come into their first biophysics course with misconceptions. Remember these important points when you take your biophysics course to help you succeed: [more…]

Surfing the World Wide Web of Biophysics

You can find many biophysics websites on the Internet, with many of them focused on specific areas of biophysics. A few websites to visit initially in your search are the following: [more…]

What Are Some Biophysical Sources of Energy?

Biophysics has many different sources of energy, which involves converting forms of energy into electrical and magnetic energy, or vice versa. The following list covers a few of these common energy sources [more…]

Biophysics For Dummies Cheat Sheet

Biophysics is the union of biology and physics. Physics is the study of the laws that the natural universe obeys, whereas biology is the study of life. Biophysics is an attempt to understand the laws that [more…]

How Running Shoes Work

Humans have been running for millions of years. Large forces are produced at the foot–ground interface when running. The force from the ground stops the downward motion and slows the forward motion of [more…]

Why Ankle Supports Help Prevent Sprains

An ankle sprain is one of the most common injuries in sport and recreation. Typically, the ligaments on the outside of the ankle are sprained when someone “rolls” his or her ankle. [more…]

What Causes Low-Back Pain

Low-back pain affects many people. It’s often said that a person with low-back pain suffers from a “slipped disk,” but the better term is a bulging disk. [more…]

Positive and Negative Phases of Weightlifting

Talk in a weight room among experienced lifters may revolve around “doing negatives.” This doesn’t mean they’re going to stop exercising and go for a snack. “Doing negatives” refers to a particular way [more…]

Biomechanics For Dummies Cheat Sheet

Biomechanics has all kinds of practical applications — from the construction of running shoes to ankle braces to low-back pain to weightlifting. Knowing how the body moves because of the forces applied [more…]

Composing a Resultant Force Vector from Multiple Vectors

Solving for the resultant force created when multiple forces act on a body involves several steps. The steps include using the tools of math and trigonometry to work with force vectors. Using a systematic [more…]

Calculate Muscle Force at the Elbow Joint When Holding a Dumbbell

In biomechanics, a common word problem to be solved involves calculating the magnitude of the muscle force required to hold a weight in the hand. A typical problem is worded something like this: [more…]

Types of Motor Units

Each muscle in the body includes many motor units. A motor unit consists of a group of individual muscle fibers that are activated by a single motor neuron. When stimulated by an action potential transmitted [more…]

How to Turn Around in Outer Space

Astronauts float around the interior of the space shuttle because they’re in a gravity-free environment. This creates a unique problem for the astronauts trying to get work done up there: how to turn around [more…]

10 Basic Principles of Biomechanics

The following ten principles of biomechanics provide a solid basis for looking at performance, whether it's coaching, teaching, rehabilitation, teaching a kid in the driveway, or watching a sporting event [more…]
