(Insert extension) Student Investigator: (Insert Name of Student Researcher, if applicable) University of Waterloo, Department (Insert Dept Name) 519-884-4567 Ext. (Insert extension) Purpose of Study: You have been asked to take part in a research study designed to evaluate submaximal exercise tests that might be used in future studies of astronauts who will spend 3-6 months on the International Space Station. Development of these tests is necessary because NASA has directed that astronauts cannot take part in physical activities that would cause their heart rate to increase above 85% of their maximum value. The tests might also provide a safer means of evaluating physical fitness in older individuals and in patients with heart disease. Procedures Involved in this Study: As a participant in this study, you will be asked to complete the following: 1. Incremental exercise tests with legs or with arms to determine the upper limit of your exercise performance. 2. Four different intensities of two submaximal exercise protocols. The tests will be completed with each of the arms and the legs. You will do several repetitions of the tests so that we can average the responses across the different tests to reduce the normal physiological variability that occurs within a single test session. Further information about each of these tests is presented on the following sheets. Time Commitment: The maximum time requirement for these tests will be about 12 hours in the laboratory on different test days. Personal Benefits of Participation: Our major purpose in doing this research is to determine whether a simple submaximal exercise test will provide similar information to that obtained during incremental exercise tests to exhaustion. These latter tests are often applied to healthy and to people with heart disease. The results of these studies will provide the basis for proposing to the Canadian Space Agency and to NASA that fitness of astronauts can be evaluated from this type of submaximal exercise test. When we finish the studies, we will provide feedback to let you know how your responses compare to the group results. Explanation of Procedures and Risks: The risks of doing incremental exercise to your functional limit are very similar to the risks of doing heavy voluntary exercise. There is a very slight chance that an apparently healthy individual will have a cardiovascular complication that has not been previously detected during normal medical examinations. There is no way to predict this potential complication. Heart Rate – Heart rate is continuously monitored by an electrocardiograph (ECG) by placing 3 spot electrodes on the skin surface. The electrodes are normally placed in the lower portion of the chest. This procedure is entirely safe. In a very small group of individuals, a skin rash might occur due to the adhesive on the electrodes. There is no way of knowing this ahead of time. The rash, if it develops, will resolve itself within a day or so. However, you are asked to avoid scratching any rash and to keep it clean. Oxygen Uptake – We measure the amount of oxygen you take from the air you are breathing by having you breathe through a mouthpiece or face mask. Attached to the mouthpiece will be a sensor to determine the volume of air that moves into and out of your lungs, and a sample line that takes a small quantity of the air to a gas analyzer system. The mouthpiece or facemask and the volume measurement device are sterilized before each person’s use to eliminate any risk of spread of infection. If you are allergic to rubbing alcohol, then you should not participate in this study. Incremental Exercise – These tests will begin with a four-minute accommodation period in which you will pedal against a very low resistance. After this, the work rate will increase progressively until you are unable to continue to do the exercise due to sensations of fatigue. The total test duration will be approximately 10-20 minutes. We ask that you push yourself to the point where you feel that it is impossible to continue at the required rate. This maximal effort is necessary because we need to be able to compare our results with a very large database of previous research in which the participants have pushed themselves to their limit. Incremental exercise does have some risk. We will not include individuals who have high blood pressure (resting diastolic pressure over 90 mmHg during a measurement in our lab) or who have been told by their doctor that they have some form of cardiovascular disease. It is impossible to predict whether apparently healthy individuals might have some previously undetected cardiovascular disease that might cause a heart attack or arrhythmia (irregular heart beat) during strenuous exercise. The sensation of fatigue that you experience during incremental exercise will probably be similar to that experienced previously during some voluntary activities. The sensation of fatigue should quickly disappear after the test. Submaximal Exercise – These tests will place less stress on your body than the incremental exercise because the upper limit for work rate will be maintained at 85% or less of your maximum measured in the incremental tests. At the 85% work rate, you might experience some sensations of fatigue because you will be asked to maintain this intensity for up to six minutes. All submaximal exercise tests will start with a warm-up period of four minutes before the work rate is increased to the required level. Stopping the Session: If you experience any sensation that appears to be unusual to you (i.e. not what you would expect during voluntary maximal exertion), then you can stop the exercise and inform the researchers of this. Special Instructions: Participants are asked to refrain from drinking alcohol in the 24-hour period immediately prior to testing. Participants should eat a normal mixed diet prior to the tests. Dietary manipulation might affect the way in which muscle units fatigue and this could influence the experimental results. Health Status Screening Form: This questionnaire asks some questions about your health status. This information is used to guide us with your entry into the study. Contraindications to participation in this study include any injury that makes exercise uncomfortable, any kidney problems, or any cardiovascular diseases including bleeding disorders, or any respiratory diseases. Changing Your Mind about Participation: You may withdraw from this study at any time without penalty. To do so, indicate this to the researcher or one of the research assistants by saying, "I no longer wish to participate in this study". Confidentiality: To ensure the confidentiality of individuals’ data, each participant will be identified by a participant identification code known only to the principal investigator and his research assistants. Participant Feedback: After the study is completed, you will be provided with a feedback sheet that will include summary graphs of your performance.
