YThere is research showing that PDL is not associated with heart rate and fatigue in older individuals. However, PDL is used to determine the loading density and is mostly recommended. In addition, it is thought that elderly individuals may be more successful in intermittent walking tests and may continue the test for a longer period of time, as opposed to continuous walking tests. In order to solve this problem, it is necessary to measure the lactate level and post-test muscle strength, which objectively indicates that the density is formed. For these reasons, the aim of this study is to examine the fatigue level of adults in intermittent and continuous walking tests in terms of perceived difficulty level, isometric muscle strength, HR and lactate levels. 
Method:
Approximately 70 volunteer adults aged 50-75 years will be included in the study. 6-minute walking test and interval walking test, heart rate (HR), isometric muscle strength measurement, perceived difficulty level (PDL) and blood lactate level (La) measurement will be performed. Persons who meet the criteria for participation in the study will be invited to the research center twice. Each participant was informed about the research structure and possible risks, and written and signed consent of the participants will be obtained through the "Voluntary Consent Form". Participants will be asked to avoid vigorous activity in the 24 hours before the test and to record what they ate all day the day before the first session so that they eat similarly before the other sessions. All test sessions will be held at the same time of the day, between 09:00 and 10:00 in the morning, when the ambient temperature is 22-23 °C. 

Expected results:

Intermittent loads instead of continuous testing/exercise make it possible for the individual to withstand stimuli longer (Laursen & Buchheit, 2019). However, most of the tests used in this group are performed in the form of continuous walking. It is thought that intermittent tests will allow to complete the test and continue for a longer time, especially in elderly individuals, and more realistic results can be obtained. In addition to studies indicating that PDL is a strong marker in elderly individuals, there are studies showing that PDL is not associated with heart rate and fatigue. With this research, it will be possible to determine with which application method the real fatigue level is reached.
