Roybal Via Habit Formation

This pilot study will develop and evaluate ViaHabit, a personalized walking intervention designed to promote physical activity habit formation among sedentary midlife adults (ages 45-65). During an initial 2-week observation period, participants' daily routines will be characterized using data collected from wearable devices, smartphones, and digital calendars. Personalized models will identify routine transitions, defined as periods between everyday activities, that may serve as receptive opportunities for initiating physical activity. Participants will then complete a 4-week intervention in which they create individualized "if-then" action plans linking routine transitions to a 15-minute brisk walk and receive automated smartwatch prompts at selected cue times. The study will assess the feasibility and acceptability of identifying routine transitions and delivering timely physical activity prompts, while exploring changes in walking behavior, habit strength, and physical activity engagement.

Comparing the Effects of Smart App-Assited Super-Slow Jogging and Stationary Cycling on Respiratory Function and Aerobic Fitness in College Students

As health awareness continues to rise, more people are prioritizing exercise to improve physical condition and enhance overall fitness. For those lacking exercise habits, selecting a simple, accessible, and effective workout becomes crucial. Against a backdrop of prolonged sitting and inactivity, "super slow jogging" is gaining attention. This aerobic exercise involves a slow walking pace and low intensity, yet burns more calories than regular walking, making it an ideal entry-level activity for beginners or those with lower fitness levels. This study aims to investigate whether incorporating super slow jogging training can effectively enhance cardiorespiratory fitness and respiratory function, comparing its outcomes with other exercise types. The purpose of this experiment is academic research, primarily exploring the impact of exercise intervention on physiological functions. It is not intended for health screening or medical diagnosis.

Impact of a Physical Activity Intervention on Sleep Quality, Mental and Physical Well-Being in Health Sciences Students

This randomized controlled trial aims to compare the effects of a regular weekly physical activity program versus a "Weekend Warrior" activity pattern on sleep quality, physical well-being, and mental well-being in sedentary university students. Participants will be randomly assigned to one of the intervention groups or to a control group and assessed at baseline and after the intervention.

Yoga vs. Stretching-Strengthening: Physical Fitness in Sedentary Young Adults

The goal of this clinical trial is to learn if yoga or stretching-strengthening exercises are more effective in sedentary young adults who are currently healthy but at risk due to inactivity. The main questions it aims to answer are: Which exercise type leads to better improvements in physical fitness, mental well-being, and sleep quality based on a person's starting profile? How do initial levels of balance and muscle strength affect how well a person responds to these exercises? Researchers will compare a yoga group to a stretching-strengthening exercise group to see if one approach is more effective than the other for specific types of individuals. Participants will: Be evaluated for their starting physical fitness (balance and strength) and psychological health. Perform either yoga or stretching-strengthening exercises regularly during the study period. Complete surveys about their mood, stress levels, and sleep quality. Be re-tested at the end of the program to measure changes and improvements.

Blood Pressure Following Isometric Exercise in Inactive Adults

This study investigates how isometric exercise training (IET) affects blood pressure in physically inactive adults. Isometric exercise involves sustained muscle contractions without movement-for example, pushing against a fixed object. Previous research has shown that IET may help reduce blood pressure, but the mechanisms involved are not fully understood. The purpose of this study is to assess both the immediate (acute) and long-term (chronic) effects of IET on cardiovascular outcomes. Participants will complete a series of lab-based exercise sessions over several weeks. In these sessions, they will perform repeated bouts of isometric leg extensions while seated on an exercise machine designed to measure muscle force. Throughout the study, researchers will monitor participants' blood pressure, heart rate, and muscle activity. Acute responses-such as post-exercise hypotension (a short-term drop in blood pressure)-will be measured immediately after exercise. Chronic changes, such as resting blood pressure improvements, will be evaluated across the training period. Additional measurements will include heart rate variability (HRV), which gives insight into autonomic nervous system activity, and electromyography (EMG), which tracks muscle fatigue and activation patterns. These data will help explore potential mechanisms behind the cardiovascular benefits of IET. By examining how repeated sessions of isometric exercise influence blood pressure and related physiological responses, this research may support the use of IET as a non-pharmacological strategy for managing or preventing hypertension in physically inactive individuals.
