Tokyo, Oct. 2 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062993) titled 'Effects of Chilled Food Ingestion on Physiological Strain and Subjective Perceptions during Walking Exercise in the Heat: A Randomized Controlled Trial' on Oct. 2.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Open -no one is blinded Control - Active

Primary Sponsor: Institute - Musashigaoka Junior College

Condition: Condition - Healthy adults Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The objective of this study is to investigate and compare the effects of ingesting chilled solid food versus fluid controls before exercise and during mid-exercise rest on core gastrointestinal temperature, physiological responses (heart rate and blood pressure), and subjective perceptual ratings (thermal sensation, thermal comfort, perceived exertion, and gastrointestinal distress) during intermittent walking exercise under hot environmental conditions. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - Ingestion of chilled solid food before exercise and during mid-exercise rest. Interventions/Control_2 - Drink cold water before exercise and during rest periods between exercises.
