2) By influencing a person's food choices
Answer:
Such activities rely mainly on Type I (slow-twitch muscles) which sustain maximal contraction for extensive periods of time. This use of slow-twitch muscles, and the availability of oxygen, prevents the buildup of lactic acid, and typically does not result in substantial muscle fatigue in the short-term.
Explanation:
The combination of forces produced by different parts of the human body. When a person is moving or attempting to move an object, several different parts of the body act together to maximize the force. In theory, force summation occurs when all body parts act simultaneously In practice, the strongest and lowest body parts around the centre of gravity (e.g. trunk and thighs) move first, followed by the weaker, lighter, and faster extremities. This is known as sequential acceleration and results in successive force summation. To obtain a maximum force, summation also needs sequential stabilization of body parts, with some body parts having to be fixed at stable points while other parts produce the effective forces.
Answer:
315 lb
Explanation:
Seeking variations in training is the best way to achieve satisfactory results during competitions. Dual progressive training is one of these necessary changes in the preparation routine. Running with a gradual increase in effort may be the best secret for completing tests in less time and with less physical effort. The progressive double training makes the body adapt to the effort it will require, acting in a less painful way. Some runners, because they start a race faster than normal, suffer from declining production later on. But this gradual training makes the athlete run more `correctly '
A client who progressed from eight 300-pound squat reps to 12 equal-weight reps using dual progressive training could do 315 lb weight squats.
