cycling modalities.
Testing Considerations
Prior to all testing and exercise days you are required to refrain from exercise for at least 48 hours. Participants are also required to abstain from taking any stimulants or depressants (including caffeine or alcohol) for at least 12 hours prior testing. Finally, participants are also encouraged to maintain a normal diet and drink plenty water the day of and the day before testing.
Risks
• You will expect muscle soreness for few days after performing eccentric cycling.
• During the experiments venous blood will be collected from the forearm using needle punction. In total 38 venous punctions will be performed within 7 weeks, (5 per each OGTT). Bruising to the area where the blood will be collected may occur. There is also a small risk of infection, but this will be minimised using aseptic procedures. This is a standard procedure with no reported adverse reactions or outcomes. A trained researcher, accredited with the procedure, will conduct the procedures.

• To place the electromyography electrodes, the skin must be shaved and cleaned. However, some skin irritation would be produced after shaving.
• During baseline measures for VO2max and maximal strength you may feel fatigue and soreness for a
few days.
• The mouthpiece utilized to collect the air and gases production/consumption may be uncomfortable to maintain for a long period of time.
Benefits
• You will be able to know your maximal aerobic capacity measured by modern equipment.
• You will be able to experience three 30-minutes training bouts performing conventional concentric cycling training and a novel cycling training (eccentric cycling).
• You will be tested for insulin sensitivity, which is one of the main parameter for diabetes mellitus diagnosis. Furthermore, you will be able to look at the influence of exercise on this parameter. • You will be able to find out about the metabolic cost of concentric and eccentric cycling exercise.
Confidentiality of Information
Your anonymity is ensured as much as is possible during the investigation and, by the assigning of number codes to subjects by the investigator. All information provided by you will be treated with full confidentiality. Your contact information will only be accessible by the Chief Researcher during the period of the study. The information and data gathered from you during the study will be used to answer the research question of this study. People who will have access to the raw information for this study are only limited to the researcher and the Supervisors. Data collected will be stored in a password-protected computer and is only available to the researchers. Hard copy data (paper etc) will only be kept in the researcher’s office and locked in a specific drawer/filing cabinet. All data will be stored according to ECU policy and regulations following the completion of the study.
Results of the Research Study
The results of this study are intended for completion of a PhD by Research thesis and may be presented in conferences/seminars and published in peer-reviewed journal(s), as magazine articles, as an online article or part of a book section and reports. Published results will not contain information that can be used to identify participants unless specific consent for this has been obtained. A copy of published results can be obtained from the investigator upon request.
