From would be undertaking beforehand therefore there wasn’t

From the results obtained from this practical it is clear to distinguish that the effect upon which exercise has on the heart rate and blood pressure is increased as the workload increases and exercise is continued for a longer time.

 Although a psychological effect should occur before the onset of exercise, as a means for the body to prepare itself for the physical activity ahead, the heart rates recorded for both rest and anticipation didn’t show any variance for either subject but remained at similar rates. This could have been due to the fact the subjects were already aware of the exercise they would be undertaking beforehand therefore there wasn’t really much anticipation being felt.As the weight load increases there is a significant difference in the increase from each level for both heart rate and blood pressure. The rate in which the heart rate and blood pressure begin to increase gives an indication on how fit the subject is and how fast their body is able in coping with exercise and adjusting itself each time as a heavier workload was placed on the machine. The increase venous return to the heart causes the force of the hearts contraction to increase immensely which then gives rise to the systolic blood pressure.

Within the practical by the time the heaviest load of the weights was applied each of the subjects systolic readings were ranged between 160-200+.During the recovery phase the heart rates for each subject still remained high and had not reached back to baseline levels within the time given. This indicates a lack of fitness within the subjects as their bodies needed a longer recovery time in which to restore their heart rate and blood pressure back to normal. Professional athletes are able to recover much quicker and restore their heart rate and blood pressure back to normal as their bodies and hearts are adapted to demanding physical exercise.They don’t have as high heart rates because their hearts have been adapted to coping with regular vigorous exercise.

This is due to the fact their hearts are able to exert a greater amount of blood within just one heartbeat than a person who does little exercise can. Therefore their heart rates don’t need to be as high in order to deliver the body the essentials nutrients it requires. In contrast the heart rates of the subject remained comparatively high which suggests they needed a much longer recovery time in order from them to return back to baseline levels.
