Trial Summary

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It focuses on increasing physical activity and fitness, so it's best to consult with the trial organizers or your doctor for guidance.

What data supports the effectiveness of the treatment Physical Activity, Exercise, Physical Exercise, Physical Activity Intervention for heart disease and obesity prevention?

Research shows that physical activity and exercise can help with weight loss, improve cardiovascular risk, and enhance exercise capacity, which is linked to better quality of life. Additionally, exercise can positively influence heart disease by increasing exercise tolerance, controlling risk factors, and potentially affecting the progression of coronary artery disease.12345

Is physical activity generally safe for humans?

Physical activity is generally safe for humans, with few serious adverse events reported. Minor issues, like muscle or joint injuries, can occur, especially in sedentary or older individuals, but starting slowly and gradually increasing intensity can help minimize these risks.678910

How does physical activity as a treatment for heart disease and obesity prevention differ from other treatments?

Physical activity is unique because it is a natural, non-drug approach that helps prevent heart disease and obesity by improving physical and mental health, controlling weight, and reducing body fat. Unlike medications, it involves regular exercise, which can be tailored to individual needs and integrated into daily life.1112131415

What is the purpose of this trial?

This study has the goal to increase physical activity and fitness among Latinos in San Diego, California and Mexicali, Baja California (U.S.-Mexico border) since these cities have similar diseases such as high rates of heart disease and obesity. Therefore there is a need to have physical activity programs for children and their families. We will collaborate with community centers to have this program available.

Eligibility Criteria

This trial is for underserved Latino families living near the U.S.-Mexico border, specifically in San Diego and Mexicali. It aims to help those at risk of heart disease and obesity by encouraging physical activity. Families interested in participating must be willing to engage with community center programs.

Inclusion Criteria

I am a parent and I am 18 years old or older.
My child is between 6 and 11 years old.
Living in the target community (within 5 miles of one of the targeted community centers)

Exclusion Criteria

Presence of a medical or physical condition that is contraindicated to participating in sports/exercise (e.g., negative score on the Physical Activity Readiness Questionnaire (PAR-Q))

  • Physical Activity
Trial Overview The intervention being tested is a program designed to promote physical activity among Latino families. The study will work through local community centers, aiming to improve fitness levels and reduce the risk of cardiovascular diseases and obesity.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Intervention ProgramExperimental Treatment1 Intervention
The 12-month intervention will progressively increase in intensity \& complexity to teach parents/children more complex sports skills \& behavioral techniques, \& to prepare them to become future team leaders for nutrition education and sports sessions. In addition, the family Olympics events will take place after every 3-month to reinforce progression, social support, \& progressive improvements: Phase 1: Beginner (months 0-3) will focus on introductory concepts \& basic sports skills \& will focus on establishing consistent behavioral patterns \& social support. Phase 2: Intermediate (months 4-6) will begin to introduce slightly more complex nutrition \& behavioral concepts, increase difficulty of sport skills, \& reinforce behavioral patterns from phase 1. Phase 4: Advanced (months 10-12) will teach parents \& children advanced sports skills \& nutrition knowledge so that they may become team leaders to help implement future activity sessions and nutrition education sessions.
Group II: Control GroupActive Control1 Intervention
Centers that are randomly assigned to the control group will continue with regularly schedule programing and activities. Families recruited from control centers will be allowed to take part in all the programs offered at the recreation centers, with exception to the AFL program since it will not be offered at those centers. Control group families will also receive publicly available information regarding the benefits of PA and strategies to become physically active (e.g., CDC PA guidelines websites \& handbook). 12-month sustainability phase will involve assessments at the organizational and individual levels. At the organizational level, we will examine the number of AFL sessions held at each recreation center and document the number of phone consultations, length of calls, and barriers addressed. At the individual level, we will examine the number of minutes of adult and child habitual PA.

Findings from Research

Exercise has numerous benefits for individuals with obesity, including aiding in weight loss and improving cardiovascular health, but the direct impact on weight loss from exercise alone is modest, typically resulting in only a few kilograms of weight loss.
Physical activity is crucial for managing type 2 diabetes and preventing its complications, and a structured approach like the 5 A's strategy can help healthcare professionals effectively support patients in overcoming barriers to increasing their physical activity levels.
Physical activity in management of persons with obesity.Oppert, JM., Bellicha, A., Ciangura, C.[2021]
Regular exercise significantly increases markers of exercise capacity, such as VO2max and ventilatory threshold (VT), which can enhance overall quality of life, especially for patients with health limitations.
Exercise serves as a positive health recommendation that not only improves physical fitness but may also indirectly encourage patients to adopt healthier behaviors, contrasting with traditional negative health advice.
Physical activity and exercise training prescriptions for patients.Foster, C., Cadwell, K., Crenshaw, B., et al.[2019]
Exercise is crucial for managing heart disease, and patients should undergo careful screening to create a safe and effective exercise prescription based on their test results.
Moderate-intensity exercise or exercising under medical supervision is recommended for safety, and these programs have been proven to enhance both the quality and quantity of life for heart disease patients.
