Welcome to the Physics of Strength
What make a person strong? According to Frederick Hatfield, Ph.D. and former world record holder in the Squat, there are 38 factors affecting strength. I have put them here for you to read quickly, but the original article can be found on www.drsquat.com.
1. Muscle Fiber Arrangement
2. Musculoskeletal Leverage
3. Tissue Leverage
4. Freedom of Movement Between Fibers
5. Tissue Viscoelasticity
6. Intramuscular/intracellular friction
7. Ratio of Fiber Types
8. Range of Motion
9. Freedom From Injury
10. Connective Tissue Structure
11. Stretch Reflex
12. The Feedback Loop
13. Endocrine System Functions (hormones)
14. Extent of hyperplasia (cell splitting) or fiber fusion
15. Extent of myofibrillarization
16. Motor Unit Recruitment
17. Energy transfer systems' efficiency
18. Extensiveness of capillarization
19. Mitochondrial growth and proliferation
20. Stroke volume of the left ventricle

22. Pulmonary (ventilatory) capacity
23. Efficiency of gas exchange in the lungs
24. Heart rate
25. Max VO2 uptake
26. Freedom from disease
27. Arousal Level ("psych")
28. Ability to concentrate
29. Incentive
30. Social learning
31. Coordination
32. "Spiritual" factors
33. The "placebo" effect
34. Equipment
35. Environment
36. Effect of gravity
37. Opposing and assisting forces
This pretty much covers everything. As you can see, it takes a culmination of physical, natural, mental, spiritual, and psychological factors to be strong. It also takes time. The laws of physics play a huge role in what it means to be strong. On this site we will focus especially on the last two, the effect of gravity and forces. The physical concepts that will be used in this site include Newton's laws (of course), gravity, work, power, velocity and acceleration, static equilibrium, and conservation of mechanical energy. All concepts and useful equations will be explained as they are used.
What is the Squat?
The parallel squat (shown to the left) is the most important lift in all of sports and the most efficient exercise in building strength. It incorporates back and leg strength, stability, and coordination. Almost every athlete can benefit from doing squats.
How do you do Squats?
Squats are done with a weighted bar on your shoulders, in the natural groove between the muscles, with your feet a little farther than shoulder-width apart.
“Strength does not come from physical capacity. It comes from an indomitable will.”(Mahatma Gandhi). When you have the will to do something or you feel strong enough to accomplish something you do not need physical strength. An example of this is when Gandhi had his biggest protest in 1930. He led over thousands of Indians on an over 200 mile march to a town on the coast. The reason they did this is to stand up to the British which had a monopoly on salt. 60,000 people were arrested including Gandhi which shows even though they weren’t strong enough to stand against the law they still achieved their goal of protesting the salt monopoly. Chris also has similar quote to Gandhi’s and that quote is “It’s not important, in life to be strong…. but to feel strong”(Chris McCandless).

One should always stretch and work on flexibility, but as well as build a stronger core, legs, and back to have a greater outcome when performing deadlifts. Proper equipment is also a must to keep one safe. Shoes, clothes, proper lifting space, and weights. The deadlift does require technique and skill, and one should never just load a bar up, and try to hit an amount of weight that would tear, strain, or pull a ligament or muscle. Strength gains in deadlifting can progress quickly, and that should be the focus for most athletes, but not to push the progression to the point where there is an injury. Proper rest between deadlift days can help avoid injuries as
And I’m not talking about strong like The Hulk, I mean strong mentally. I remember one season when Riley struggled to get faster, and after every race, you could see her frustration. But it didn’t make sense to me, she was the hardest working person I have ever met. She outworked us all.After a while, I started noticing that she started cheering at meets more, she was more encouraging at practice and she just made the overall atmosphere of the team more positive. The rest of the team started to get faster. A few weeks later, Riley started to drop time. It was like she used everyone else’s success to propel her own. Instead of giving up, she found a way to persevere and maintain a positive attitude, because of this she actually got even faster. Riley’s second superpower was a strong-willed
My five strengths according to the strength finder include; balance, this helps me be aware of treating all people equally regardless of the situation. I am neither in anyone 's favor or against anyone as this to me is selfishness and individualism. This would result in a situation where some people scale heights due to connections while others are lagging behind. I believe that a consistent environment where the rules apply to everyone is the best for individuals to function best (Rath, 2007). Flexibility is my next strength. By knowing that things do not always work out as planned has helped me change the tactics of how I perform my tasks. I do not always expect to have a smooth flow of opportunities or accomplish goals, but
It is Isometric. This means that it is performed in a static position. By so doing, the force of the muscles contracts over the bones, making them thicker and stronger.
Toughness is just a term that many individuals use to describe they’re ability to believe that their not weak in any way. Playing the game of basketball and being a part of the team is more than just being tough. Basketball is more of being determined, strong, and willing to become a better athlete. When you have the mindset that I am tough and no one can give you pointers to make your game better. Does not make you an athlete nor makes you tough. What makes any ball player tough are the struggles and the process you go through to make you better. We as players have our ups and downs. As soon as we give up, were no longer determined, strong, and willing. As soon as we give up this problem is what makes us weak, and what coach wants a weak player on their team that gives up in any possible way. There are three words that describe the term tough and these words are being determined, being strong , and willing to learn and become an overachiever in the game of basketball.

Strength is a term with many definitions. What does strength mean? Anyone can sit down and start to write down their strengths but, how many different types of strengths are there? There are personal strengths, mental strengths, and spiritual strengths that all have a positive effect on people’s lives. Throughout life, strength is what helps overcome the problems we face. Strength is defined by Dictionary.com as “a good or beneficial quality or attribute of a person or thing.” No matter what kind of strength different people in society have; strength is something gained through personal experiences and life. Strength is having the mind set to overcome all of life’s challenges and battles.
Strengths and weaknesses are important for leaders to understand in order to create a successful movement; however, nobody is born with strengths. Everyone has naturally occurring talents that are individual to themselves. Over time, applying a talent repeatedly will develop that trait into a strength, which can then be applied to any situation one may encounter.
The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
Everyone has their own definition of a strong person. A strong person to me is a person that can overcome the adversities in life positively. My friend Ivery, my dad, and my sister can be boldly described as a strong person in so many ways. In order to be characterized as a strong person you have to be stable-minded, courageous, and honest. Every strong person has their own character traits but there are some that stand out more than others. Some people may define people strong by their physical strengths. Others might say you are strong because you didn’t cry when you should have cried. Defining a strong person is based off of your perception of something. There are three people that demonstrate strong qualities as an individual.
