Answer:
In most cyclic movements, the ability of muscles to quickly relax or reduce tone and muscle strength allows for more efficient expression of agonist muscle strength during certain phases of movement.
Explanation:
Several movements are based on relatively short activities of the corresponding muscle groups (rapid individual movements or postural corrections) or alternating activations of antagonistic muscle groups (walking, running, throwing, kicking). The time required to perform most of these movements is limited and is often equal to the duration of explosive operations.
<span>The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.
Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.</span>
