研究概览
简要总结
A single-center, randomized, placebo-controlled study in community dwelling, healthy, regularly exercising, highly physically fit men and women, 19 to 40 years. Eligible participants will be randomized to receive either 1000 mg NMN or placebo twice daily for 10 weeks.
详细描述
The study participants will be screened for potential participation and those meeting eligibility criteria on screening will be offered participation in the study. 120 subjects will be block randomized in a 1:1:1:1 ratio, stratified by sex (male, female) and baseline VO2 max. Participants will be randomly assigned to one of four groups using a 2 by 2 factorial design: Group 1 - MIB-626 (MIB-626 - UPA) plus usual physical activity; Group 2 - standardized, progressive, high intensity, multidimensional exercise plus placebo (PL-Ex); Group 3 - MIB-626 plus standardized, progressive, high intensity, multidimensional exercise (MIB-626-Ex); Group 4 - placebo plus usual physical activity (PL-UPA).
