Final answer:
The goal for elite athletes in the two-arm loaded carry exercise is to carry their body weight or more. The power required for such a task can be estimated similarly to the power exerted during pull-ups by an army trainee, using the formula Power = Work/Time. The concept of force distribution is also important in these exercises.
Step-by-step explanation:
With regard to the two-arm loaded carry exercise, the goal for elite athletes is to carry their body weight or more across a set distance. This exercise mimics real-life challenges where an athlete may need to move heavy loads efficiently. To estimate the power exerted in such a task, one could look to analogous exercises like the trainee doing pull-ups.
Using the example of the army trainee doing pull-ups, we can calculate the power required. If the trainee weighs 80 kg and it takes 0.8 seconds to complete a pull-up, the power can be estimated using the formula Power = Work/Time. The work done is equivalent to lifting the body against gravity, thus Work = weight × height. Assuming a reasonable height the trainee lifts themselves, the power can be found. Similar principles apply to the loaded carry, where depending on the weight carried and the distance, the power output can be calculated.
Understanding the concept of force distribution as explained with the pole vaulter and force exertion in carrying exercises helps in framing the functional fitness goals and strategies of athletes, particularly with exercises like the loaded carry.
