    measure the heart rate and ventilation rate before‚ during and after moderate exercise. Introduction: I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually

    What affect does exercise have on these parts of your body? Heart‚ Lungs‚ Muscles‚ Joints and Body Temperature? After exercise‚ you’ll find your body experiences immediate and more gradual effects. The minute you start training‚ you’ll notice more frequent muscle contraction‚ raised body temperature and pulse‚ and deeper breathing known as tidal volume. Longer-term effects occur as the body adapts to regular exercise‚ including your heart getting larger‚ bones becoming denser and the vital capacity

    the experimental hypothesis was accepted. These findings could be due to the negative phototactic response that occurs when they are exposed to visible light that are above 600 Mn (nanometers) that are also considered the color red. This shows that Daphnia have a greater phototactic reaction to red light than when exposed to white light. When compared to a similar study‚ the same result was found. It was reported that there was a significant difference in the Daphnia’s phototactic reaction when exposed

    How Does the Change of Mass Affect the Rate at Which an Elastic Powered Car Accelerates? Research Question: How does the change of mass affect the acceleration of the Lego Car powered by elastic? Hypothesis: it was thought that the more weight added to the body of the Lego Car would slow down the initial acceleration‚ but the car would travel a longer distance due to increased momentum‚ which might overcome kinetic friction. Rationale: Some reasons of why that it was thought

    different adrenalin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart rate. Background The endocrine system works with the nervous

    How exercise affects certain aspects of the body During exercise our body needs more oxygen and blood to keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the

    example of a heart rate is called resting heart rate. The resting heart rate of the body is the number of contractions of the heart that occur in a single minute while the body is at complete rest. The resting heart rate can differentiate upon age‚ gender‚ and health of a human. There will also be a difference in number upon the resting heart rate of athletes and a non-athletes. I calculated 68 beats per minute for my resting heart rate. Another example of heart rate is target heart rate. Mathematically
