About this study
Official title: Dietary Fat Quality, Metabolic Health, Cognitive Function, and Responses to Standardized Moderate-Intensity Exercise in Young Adults
Regular physical activity, healthy dietary habits, and good metabolic health are associated with numerous physical and cognitive health benefits. However, individuals vary substantially in their affective, motivational, and cognitive responses to exercise, and the factors contributing to this variability are not fully understood.
This prospective observational study will examine whether habitual dietary fat quality and metabolic health are associated with exercise responses, cognitive function, and academic-related outcomes in healthy young adults. Participants will complete assessments of dietary intake, body composition, metabolic health, aerobic fitness, cognitive function, and academic engagement. They will also complete a standardized moderate-intensity cycling session during which affective responses, exercise enjoyment, subjective energy, and motivation for future physical activity will be assessed.
The findings will improve understanding of how habitual dietary habits and metabolic health may influence responses to exercise and cognitive functioning and may help inform future lifestyle recommendations aimed at promoting physical activity participation, cognitive performance, and overall health.
Read the detailed description
Regular physical activity and healthy dietary patterns contribute to the prevention of chronic disease and support cognitive and psychological well-being. Nevertheless, individuals differ considerably in their responses to exercise, including perceived enjoyment, affective responses, motivation to continue exercising, and cognitive performance. These individual differences may influence long-term physical activity participation and adherence, yet the biological and lifestyle factors underlying this variability remain incompletely understood.
Habitual dietary fat quality and metabolic health have been independently associated with cardiometabolic function, cognition, and psychological well-being. Greater saturated fat intake and poorer metabolic health have been linked to impaired cognitive performance, increased inflammation, and reduced insulin sensitivity, whereas diets higher in unsaturated fats have been associated with more favorable metabolic and cognitive outcomes. Whether these factors also influence acute psychological and cognitive responses to exercise has received comparatively little attention.
The purpose of this prospective observational study is to examine associations among habitual dietary fat quality, metabolic health, cognitive function, and responses to a standardized bout of moderate-intensity exercise in healthy young adults. Habitual dietary intake will be assessed using multiple-day dietary records, and metabolic health will be characterized using anthropometric measurements, fasting glucose, blood lipids, oral glucose tolerance testing, body composition, aerobic fitness, and salivary cortisol. Cognitive function, mental fatigue, concentration, cognitive failures, and academic engagement will also be assessed.
Participants will complete a standardized moderate-intensity cycling session during which affective responses, perceived exertion, subjective energy, exercise enjoyment, and motivation for future physical activity will be measured before, during, and after exercise. The exercise session serves as a standardized assessment designed to evaluate individual variability in physiological and psychological responses rather than as an intervention intended to improve health outcomes.
The primary objective is to determine whether habitual dietary fat quality and metabolic health are associated with affective responses to exercise. Secondary objectives include examining associations with exercise enjoyment, motivation for future physical activity, cognitive performance, mental fatigue, concentration, academic engagement, and selected physiological measures. Findings from this study may improve understanding of modifiable lifestyle factors associated with exercise adherence, cognitive functioning, and overall health in young adults and inform future behavioral and lifestyle interventions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standardized Moderate-Intensity Cycling SessionBehavioural
Participants will complete a standardized 30-minute moderate-intensity cycling session on an electronically braked cycle ergometer. Exercise intensity will be prescribed at approximately 50-60% heart rate reserve (Borg Rating of Perceived Exertion 11-13). Heart rate, perceived exertion, affective responses, exercise enjoyment, subjective energy, and motivation will be assessed before, during, immediately after, and following exercise. The cycling session is conducted as a standardized assessment procedure for all participants and is not assigned as an experimental intervention.
| Study group | Role | What they receive |
|---|---|---|
| Healthy Adults | Participants aged 18 years and older who meet eligibility criteria will complete assessments of habitual dietary intake, metabolic health, body composition, aerobic fitness, cognitive function, academic engagement, and responses to a standardized moderate-intensity cycling session. All participants will follow the same study procedures. Dietary fat quality and metabolic health will be treated as naturally occurring exposures rather than assigned interventions. Receives: Behavioral: Standardized Moderate-Intensity Cycling Session |
What is being measured
The primary outcome is the main question the study is designed to answer.
Affective Valence During and After Exercise
Affective valence will be assessed using the single-item Feeling Scale. Scores range from -5 ("very bad") to +5 ("very good"), with 0 representing "neutral." Higher scores indicate more positive affective valence and therefore a better affective response.
Measured: Immediately before exercise; at minutes 5, 10, 15, 20, and 25 during the 30-minute cycling session; immediately after exercise; and 30 minutes after exercise
Perceived Arousal During and After Exercise
Perceived arousal will be assessed using the single-item Felt Arousal Scale. Scores range from 1 ("low arousal") to 6 ("high arousal"). Higher scores indicate greater perceived arousal and are not inherently a better or worse outcome.
Measured: Immediately before exercise; at minutes 5, 10, 15, 20, and 25 during the 30-minute cycling session; immediately after exercise; and 30 minutes after exercise
Positive Affect Before and After Exercise
Positive affect will be assessed using the five-item positive-affect subscale of the International Positive and Negative Affect Schedule-Short Form. The five items are summed to produce a score ranging from 5 to 25. Higher scores indicate greater positive affect and therefore a better affective response.
Measured: Immediately before exercise, immediately after the 30-minute cycling session, and 30 minutes after exercise
Negative Affect Before and After Exercise
Negative affect will be assessed using the five-item negative-affect subscale of the International Positive and Negative Affect Schedule-Short Form. The five items are summed to produce a score ranging from 5 to 25. Higher scores indicate greater negative affect and therefore a worse affective response.
Measured: Immediately before exercise, immediately after the 30-minute cycling session, and 30 minutes after exercise
Secondary outcomes (6)
Exercise Enjoyment
Exercise enjoyment will be assessed using the 8-item Physical Activity Enjoyment Scale-Short Form (PACES-SF). After reverse-scoring negatively worded items, responses are summed to produce a total score ranging from 8 to 56. Higher scores indicate greater exercise enjoyment and therefore a better outcome.
Measured: Immediately after the 30-minute cycling session and 30 minutes after the cycling session
Desire to Move
Momentary desire to move will be assessed using the Move subscale of the Cravings for Rest and Volitional Energy Expenditure (CRAVE) scale. Item responses are averaged to produce a score ranging from 0 to 10. Higher scores indicate a greater momentary desire to move but are not inherently a better or worse health outcome.
Measured: Immediately before the 30-minute cycling session, immediately after the cycling session, and 30 minutes after the cycling session
Desire to Rest
Momentary desire to rest will be assessed using the Rest subscale of the Cravings for Rest and Volitional Energy Expenditure (CRAVE) scale. Item responses are averaged to produce a score ranging from 0 to 10. Higher scores indicate a greater momentary desire to rest but are not inherently a better or worse health outcome.
Measured: Immediately before the 30-minute cycling session, immediately after the cycling session, and 30 minutes after the cycling session
Everyday Cognitive Failures
Everyday cognitive functioning will be assessed using the 25-item Cognitive Failures Questionnaire (CFQ). Items are summed to produce a total score ranging from 0 to 100. Higher scores indicate a greater frequency of everyday cognitive failures and therefore a worse outcome.
Measured: At baseline, before the exercise-testing procedures
Estimated Maximal Oxygen Consumption
Aerobic fitness will be estimated during a submaximal graded cycle-ergometer exercise test with respiratory gas analysis. Estimated maximal oxygen consumption will be reported in milliliters of oxygen per kilogram of body mass per minute. Higher values indicate greater aerobic fitness and therefore a better outcome.
Measured: At baseline, during the submaximal graded cycle-ergometer test
Body Composition
Body composition will be assessed using air-displacement plethysmography (BodPod) and reported as the percentage of total body mass consisting of fat. Higher values indicate a greater proportion of body mass consisting of fat.
Measured: At baseline, before the exercise-testing procedures
