B. anaerobic activities
Pyramid activity is known to be set of weight training in which the progression is from lighter weights with greater number of repetitions in the first set to heavier weight with fewer numbers of repetitions. Thus, strength training is an anaerobic activity and it is a physical exercise that specialize in the use of resistance to induce muscular contraction that builds size of skeletal muscles, strength and anaerobic endurance.
The heavy weight lifting comes under the category of anaerobic activity in the physical activity pyramid.
Further Explanation:
The physical activity pyramid explains the amount the physical activity which is required to lead an active and healthy lifestyle. This pyramid helps understand different physical activities that are necessary for the fitness of different body parts. The pyramid is divided into four levels starting level 1 from the bottom to level 4 at the top.
The first level involves moderate physical activities that need to be performed every day. These activities include brisk walking, yard walking, skipping elevators and using stairs. It is estimated that 30 minutes of moderate physical activities must be included in daily activity.
The level 2 involves activities vigorous than moderate activities. These include aerobic dance and jogging which is done for a longer time, long enough to increase the heart rate and produces sweat in the body. Other activities include biking, running, hiking, and canoeing. These activities must be performed 3-6 days per week for about 20 minutes or more.
The exercises which provide flexibility, strength, tolerance and fitness to the muscles come under level 3 of the pyramid. These exercises involve resistance training and moving body weight. The resistance training is done with help of machine and weights while body weight is moved through jumping, calisthenics, and rock climbing. Such exercises improve body posture and appearance and make the bones stronger. These are also called anaerobic exercises as they are done intensely for a short period of time and improves muscle endurance by providing tolerance against lactic acid build-up in the muscles.
The physical inactivity is part of level 4 of the pyramid. The rest is important for the human body but too much inactivity leads to bedsores, physical ailments, and boredom. The inactivity must be limited and should involve only small part of the day.
