4 Explain why it would take you longer to perform 10 repetitions lifting a 10-kg weight than it would to perform the same number of repetitions with a. Active force data changes as the resting length of the muscle changes.

With a light load the shortening velocity is at its Maximal shortening velocity.

. The velocity of shortening decreases with a heavier load so the repetitions will take longer with a 10 kg weight. The shortening distance decreased with the heavier weights because the muscle was not able to lift the heavier weights as high as the lighter weights. A25-g weight is attached to the end of the isolated whole skeletal muscle used in these experiments.

Describe how the shortening distance changed as the load became heavier in this. Where Po is the maximum isometric force and a and b are constantsThe forcevelocity PV relation suggests that muscle can regulate its energy output depending on the load imposed on it Hill. When the weight is heavy the speed in which the muscle lifts the weight decreases in speed at a slower velocity Describe how the shortening distance changed as the load became heavier in this.

The velocity of shortening decreases with a heavier load so the repetitions will take longer with a 10 kg weight. The shortening velocity refers to the speed of the contraction from the muscle shortening while lifting a load. Describe what would happen in the following experiment.

Thesame as I predicted before the experiment. How does the shortening distance change as the load becomes heavier. This can occur only when a muscles maximal force of contraction exceeds the total load on the muscle.

The change in the active force amount is completely caused by the amount of myosis bound to actin 4. The latent period will decrease the shortening velocity will decrease the distance will increase and the contraction duration will increase. Isotonic contractions maintain constant tension in the muscle as the muscle changes length.

Maximal shortening velocity is only attained with a minimal load. Though there is controversy surrounding the mechanics responsible for the performance. Explain why it would take you longer to perform 10 repetitions lifting a 10-kg weight than it would to perform the same number of repetitions with a 5-kg weight.

Space contraction refers to the process of distance becoming shorter for fast moving objects. Cross bridges cycle and when muscle tension exceeds the load muscle shortening occurs3. How well did the results compare with your prediction.

Cross bridge cycle and when the muscle tension exceeds the load muscle shortening happens. Voltage v Length mm Weight g Velocity mmms Distance Lifted mm Time contracting Time relaxing. 4 Describe how the shortening distance changed as the load became heavier in this experiment.

My prediction was wrong with this answer as the latent period increases the distance increases and shortening velocity takes longerincreases to lift the heavier object and the contraction thus takes longerincreases. The stretch-shortening cycle SSC refers to the pre-stretch or countermovement action that is commonly observed during typical human movements such as jumping. The length of the muscle changes.

When the weight is heavy the speed in which the muscle lifts the weight. The shortening distance decreased with the heavier load. LD the load-distance value l i the load expressed as a weight number of trips or units being shipped from the proposed site to location i d i the distance between the proposed site and location i The distance d i in this formula can be the travel distance if that value is known or can be determined from a map.

Describe what would happen in the following. When the resting length of the muscle is lengthened the active force amount decreases. The velocity of shortening decreases with a heavier load so the repetitions will take longer with a 10 kg weight.

With a light load the shortening velocity is at its Maximal shortening velocity. Several types of muscle contractions occur and they are defined by the changes in the length of the muscle during contraction. The latent period occurs when there is a rise in muscle tension but no movement or contraction of the muscle.

With the lighter weight the muscle is contracted quicker in both latent and shortening velocity speeds. The latent period occurs when there is a rise in muscle tension but no movement or contraction of the muscle. The latent period will increase the shortening velocity will increase the distance will decrease and the contraction duration will increase.

5Explain why it would take you longer to perform 10 repetitions lifting a 10-kg weight than it would to perform the same number of repetitions with a 5-kg weight. The shortening velocity refers to the speed of the contraction from the muscle shortening while lifting a load. As the weight increased the latent period increased the shortening velocity decreased and the distance decreased.

Explore this process and learn about length contraction and the speed of light. The latent period increases as the weight of the load gets heavier this is for the necessary force to be generated by the muscle. This pre-stretch allows the athlete to produce more force and move quicker.

Cross bridges cycle and when the muscle tension exceeds the load muscle shortening happens. Remember to put whether or not you predicted this correctly according to the questions in the virtual lab. How well did the results compare with your prediction.

It can also be computed using the following. The shortening distance decreased with the heavier load. It would take longer with the heavier weight because as the weight of the load increases so does the latent period time and the shortening velocity speeds.

Describe how the shortening distance changed as the load became heavier in this experiment. The latent period increases as the weightof the load gets heavier this is for the necessary force to be generated by the muscle. When the resting length of the muscle is shortened the active force amount increases.

The shortening distance became smaller as the load became heavier because there is less muscle contraction occurring. P a V bPo P. Explain why it would take you longer to perform 10 repetitions lifting a 10-kg weight than it would to perform the same number of repetitions with a 5-kg weight.

The shortening distance decreases as load becomes heavier. The relation between the force load and the velocity of shortening V in contracting skeletal muscle is part of a rectangular hyperbola. It would take longer with the heavier weight because as the weight of the load.
