Power01:08

Power

13.4K
The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

Average Power

1.3K
In practical electrical applications, the concept of time-varying instantaneous power is not frequently utilized. Instead, focus shifts to the more practical quantity known as average power. Average power is determined by integrating the instantaneous power over a specified time period and subsequently dividing it by that duration.

Exercise and Cardiac Output

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Instantaneous Power01:22

Instantaneous Power

1.1K
Instantaneous power is important in electrical circuits, mainly when dealing with sinusoidal input. Instantaneous power, denoted as p(t), results from the multiplication of the instantaneous voltage (v(t)) across an element and the instantaneous current (i(t)) flowing through it. This relationship adheres to the passive sign convention and represents a fundamental principle in electrical engineering.

Maximum Power Transfer01:16

Maximum Power Transfer

1.2K
Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Power and Energy01:12

Power and Energy

2.4K
The power and energy delivered to an element are subjects of great significance in the field of electrical engineering. It is a well-known fact that a 100-watt light bulb emits more light than a 60-watt one. Therefore, power and energy calculations play a crucial role in the analysis of electrical circuits.
Power, defined as the time rate of expending or absorbing energy, is quantified in units called watts (W). The relation between power and energy is mathematically given as

Area of Science:

  • Sports Science
  • Biomechanics
  • Exercise Physiology

Background:

  • Assessing whole-body peak power is crucial for athletic performance evaluation.
  • Rowing ergometers offer a practical method for power output testing.
  • Determining optimal resistance settings enhances test validity.

Purpose of the Study:

  • To evaluate the reliability and validity of the Concept II rowing ergometer for peak power output measurement.
  • To identify the optimal resistance level for maximal power output in diverse participant groups.
  • To compare peak power output across different physical activity levels and rowing expertise.

Main Methods:

  • 87 participants (inactive students, active students, trained rowers) underwent countermovement jump (CMJ) tests and maximal rowing trials.
  • Rowing trials were conducted at three resistance settings (1, 5, 10) in a randomized order.
  • Reliability was assessed using coefficients of variation and intraclass correlation coefficients; validity was examined via correlations with CMJ peak power.

Main Results:

  • The rowing peak power test demonstrated high reliability (CV: 2.6-6.5%; ICC: 0.87-0.98).
  • Strong correlations (r = 0.70-0.78) were found between CMJ and rowing peak power across all groups and resistances.
  • Highest power output occurred at highest resistance for non-athletes (p < 0.01), but at moderate resistance for trained rowers.

Conclusions:

  • The Concept II rowing ergometer is a reliable and valid tool for assessing peak power output in various populations.
  • Optimal resistance for peak power differs between trained rowers and non-athletic individuals.
  • This test provides a valuable measure for both untrained individuals and rowing athletes.
