It is possible that lower body weight of subject 3 contributed to the better level of muscular endurance.
There are different sources of potential errors depending on subjects (fatigue, motivation, hydration, injuries), technician (level of training, experience), the equipment (calibration) and environment (room temperature, humidity). With a small number of observations and participants cost of each error is reasonably high and more difficult to detect.
Muscle power and muscle force are different terms and increasing the muscle force will not increase the muscle power if the speed of the action is decreased. The power is only increased with increasing force if velocity remains constant. The formula Power (P) = Force (F) * Velocity (V) is a basis for all martial arts when training focused on increasing both force and velocity to achieve bigger impact (power). It is important to consider that more muscular strength entails greater growth in muscle mass. Muscles with more size tend to physiologically drop in speed as a result of the need of greater recruitment of motor units for the muscle. Three types of muscle fibers provide different …show more content…
Stretching prior to exercise may increase the risk of injury. It is better to focus on gentle warming up and light stretching than on simply stretching muscles prior to intensive workout. After intense exercise, stretching helps to relax contracted muscles and avoid stiffness and soreness later. After intense exercise, stretching helps to relax contracted muscles and avoid stiffness and soreness afterward. It was noted the different level of flexibility in the subjects, with one doing significantly worse than others. Long-term benefits of properly done stretching will be especially important for this subject (subject
