Adherence Patterns and Health Outcomes in Spanish Young Women Participating in a Virtual-Guided HIIT Program: Insights from the Randomized Controlled WISE Trial.

Background/objectives: A notable decline in physical activity from late adolescence to early adulthood affects young women especially. This study aimed to investigate adherence to an unsupervised virtual-guided high-intensity interval training (HIIT) exercise program among young women in Spain.

Methods: A total of 106 participants were recruited and randomized to the Women's Involvement in Steady Exercise (WISE) trial exercise program, administered remotely via a mobile app, and a control group.

Women's Involvement in Steady Exercise (WISE): Study Protocol for a Randomized Controlled Trial.

Background: Physical inactivity is a serious public health problem for people of all ages and is currently the fourth highest global risk factor for mortality. The transition period from adolescence to adulthood coincides with a marked reduction in participation in physical activity, with more than 50% (and up to 80%) of young adults stopping physical activity. This decrease in physical activity is more evident in women than in men.
