Power Output Amongst Different Age Groups Adrian Flores, Exercise Science, HSES 473 / Dimitrije Cabarkapa, adrianflores@ku.edu Abstract In the context of fitness training, whether it is for sports performance or general health, we often hear the words cardio and lifting, which corresponds to endurance and strength. Although these are important aspects of overall fitness, another aspect that is also a crucial aspect of fitness and overall health is power. Activities that are often performed in daily living requires power. The ability to produce a significant amount of work in a period of time is far more intriguing and far more effective than strength and endurance itself. Introduction In this presentation, we will gain knowledge of evaluating power output through different exercises and tests that will later show us how power affects people’s performance and health. The general power formula is expressed as a given force divided by the time it took to complete the lift or the movement. Later we find out that the velocity component is vital because it tells us whether is specific lift or movement should be performed adequately. Body In the world of health and fitness research, there is a significant amount of studies that had a big emphasize on strength and how its importance it is to be able to perform strength-based movements like lifting, loading, and holding. As vital as strength is for human performance, power is a component that goes along with strength. Figure 2. A power test done with resistance bands attached to a Smith machine to test velocity on a squat jump. An optimal test for sport specific atheltes. Why Power? o Most of our daily tasks/routine require a good amount of velocity when lifting, standing, walking, rotating, and more. o Power is highly correlated with functional motion than strength Training for Power o Various exercises and tests can be prescribed according to their functional level, goals, mobility, balance, and some level of strength. o It’s never too late to start training for power! Body Response to Power o Increase the utilization of the fast-twitch fibers and being able to maintain those levels over time o Power will enable the body to perform any motion at a faster rate Clinical Application In a clinical setting, it is good to start with an overview knowledge of the patient; find out if that patient is at risk of any health issues. If the patient is healthy enough, we can process with their goal. If you have an elite athlete or trying to develop an elite athlete, we need to understand the type of training and muscle groups that will contribute to the sport. The implementation of free weights and machines is optimal as long as they are performing it safely. The same procedure can be done with nonathletic patients who are just looking for better functional motion. Poster References Figure 1.

Conclusions we now have a better understanding of how significant power and power training is for any individual. The interesting fact about power is that it is already part of our daily routine and training programs. Power is a variable that, in the past, we did not pay crucial attention to it. When we then later realize is that most of the movements and motions that our bodies are naturally performed, are done at a fast pace. Power training and power output amongst different age group is such a broad topic, we the concepts mentioned before are some of the key factors that will devote to better and optimal human kinetics.
