The Physics of Human Strength :: physics sport sports weight lifting strong

Welcome to the Physics of StrengthWhat make a someone strong? According to Frederick Hatfield, Ph.D. and former world record holder in the labourer, there are 38 factors affecting strength. I have tramp 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. liberty 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. consummation 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 development and proliferation 20. Stroke volume of the go forth ventricle 21. Ejectio n fraction 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. stimulant 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 forcesThis pretty often covers everything. As you can see, it takes a culmination of physical, natural, mental, spiritual, and psychological factors to be strong. It too takes time. The laws of physics play a huge role in what it convey to be strong. On this site we will focus especi every last(predicate)y on the last two, the effect of gravity and forces. The physical concepts that will be use in this site include Newtons laws (of course), gravity, work, power, velocity and acceleration, static equilibrium, and conservation of mechanically skillful energy. All concep ts 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.
