Resting skeletal muscle has a basal metabolic rate (resting energy consumption) of 0.63 W/kg [13] making a 160 fold difference between the energy consumption of inactive and active muscles. For short duration muscular exertion, energy expenditure can be far greater: an adult human male when jumping up from a squat can mechanically generate 314 ...
Trained endurance athletes can have resting heart rates as low as a reported 28 beats per minute (Miguel Indurain) or 32 beats per minute (Lance Armstrong), [5] both of whom were professional cyclists at the highest level. Aerobic conditioning makes the heart and lungs pump blood more efficiently, delivering more oxygen to muscles and organs. [6]
Aerobic exercise interventions help to improve cardiovascular endurance. [20] Anaerobic strength training programs can increase muscular strength, [ 13 ] power, [ 21 ] and lean body mass . [ 22 ] Decreased risk of falls and increased neuromuscular control can be attributed to balance intervention programs. [ 23 ]
In addition to developing overall power and endurance, they are excellent for developing the strength and mobility of the core and joints. In a study of the power output of gymnasts, Monem Jemni attests that the high peak-power outputs gymnasts are capable of place them near the top level for power athletes; notably, higher than elite level ...
Strength training is primarily an anaerobic activity, although circuit training also is a form of aerobic exercise. Strength training can increase muscle, tendon, and ligament strength as well as bone density, metabolism, and the lactate threshold; improve joint and cardiac function; and reduce the risk of injury in athletes and the elderly ...
Human-powered equipment primarily consists of electrical appliances which can be powered by electricity generated by human muscle power as an alternative to conventional sources of electricity such as disposable primary batteries and the electrical grid. Such devices contain electric generators or an induction system to recharge their batteries.
There are various ways to measure physical strength of a person or population. Strength capability analysis is usually done in the field of ergonomics where a particular task (e.g., lifting a load, pushing a cart, etc.) and/or a posture is evaluated and compared to the capabilities of the section of the population that the task is intended towards.
Endurance training is the act of exercising to increase endurance. The term endurance training generally refers to training the aerobic system as opposed to the anaerobic system. The need for endurance in sports is often predicated as the need of cardiovascular and simple muscular endurance, but the issue of endurance is far more complex.
