Subdisciplines of mechanics include. 1  Statics, the study of non-moving bodies under known loads, how forces affect static bodies. 2  Dynamics the study of how forces affect moving bodies. Dynamics includes kinematics (about movement, velocity, and acceleration) and kinetics (about forces and resulting accelerations).
1 Researchers studied a group of men that typically walk approximately 10,000 steps per day (as measured by a pedometer) and asked them to reduce their steps to only 1,350 per day. 2  This meant taking elevators instead of stairs, driving to work and lunch.
They have lost much of their thoracic extension and are bent forward shuffling along. An excellent book that can help in this area is Natural Posture for Pain-Free Living by Kathleen Porter. Many People Donât Get Close to 10,000 Steps a Day Taking 10,000 daily steps means youâve walked about five miles or 9 kilometers.Many people do not get close to reaching this goal, which is why fitness trackers can be so useful. According to the UKâs National Health Service (NHS), the average person only walks between 3,000 and 4,000 steps per day. In order to get fit, you still need to exercise in addition to your daily walks. 2  For optimal health and fitness, strive for 10,000 daily steps in addition to a regular exercise program including high-intensity interval training and strength training.
