Tokyo, Dec. 22 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000060099) titled 'To investigate the effectiveness of cooling body temperature raised by exercise in a hot environment with cold water using a heatstroke relief bag' on Dec. 22.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Open -no one is blinded Control - Dose comparison

Primary Sponsor: Institute - Osaka University of Health and Sport Sciences

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

Objective: Narrative objectives1 - The purpose of this study was to verify the effectiveness of a heatstroke relief bag, which is relatively easy to prepare and practical, and a 10-minute cold water immersion method using a small amount (5 or 80 L) of cold water (approximately 5 degree) or tap water (approximately 20 degree) on core body temperature that has risen due to exercise in a hot environment. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - The subjects entered an environmentally controlled room set at a temperature of 40 degree and humidity of 60%, sat in a chair and rested for five minutes, then walked for three minutes on a treadmill set at a speed of 5 km/h and a 2% incline as a warm-up. They then ran for 30 minutes on a treadmill set at a speed of 8-9 km/h and a 2% incline. After finishing the run, the subjects lay supine in a heatstroke aid bag and were immersed in water cooled to approximately 5 degree, which was poured over them at a constant rate, for a total of 10 minutes. Interventions/Control_2 - The subjects entered an environmentally controlled room set at a temperature of 40 degree and humidity of 60%, sat in a chair and rested for five minutes, then walked for three minutes on a treadmill set at a speed of 5 km/h and a 2% incline as a warm-up. They then ran for 30 minutes on a treadmill set at a speed of 8-9 km/h and a 2% incline. After finishing the run, the subjects lay supine in a heatstroke aid bag and were immersed in 80 liters of water cooled to approximately 20 degree, which was poured over them at a constant rate, for a total of 10 minutes.
