Study Type:
Interventional
Study Design:
Basic Design - Cross-over
Randomization - Randomized
Blinding - Double blind -all involved are blinded
Control - Placebo
Primary Sponsor:
Institute - Faculty of Sports and Exercise Science, Universiti Malaya
Condition:
Condition - Appetite regulation and exercise performance in the fasted state (healthy adults)
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - This study aims to investigate the effects of chocolate odors (dark and milk chocolate) on appetite perception and resistance exercise performance in the fasted state. The objective is to determine whether olfactory stimulation can modulate exercise capacity through appetite-related and affective pathways.
Basic objectives2 - Others
Intervention:
Interventions/Control_1 - Participants are exposed to a 90% dark chocolate odor for 30 seconds as an olfactory stimulus, followed by appetite assessment (VAS) and resistance exercise (leg extension task).
Interventions/Control_2 - Participants are exposed to a 60% milk chocolate odor for 30 seconds as an olfactory stimulus, followed by appetite assessment (VAS) and resistance exercise performance test.
