Brief Summary

Health-related physical fitness (HRPF) has demonstrated high clinical relevance, and its level is associated with the ability to perform activities of daily living with vigor and a lower risk of chronic disease. Consequently, exercise prescription guidelines recommend improving HRPF as a focus for prevention and rehabilitation programs. Measuring and tracking HRPF often requires specialized equipment and personnel, which are expensive and less applicable to the general population. Wearables may mitigate this issue by providing useful estimates of the HRPF.

Study Population

he study population consists of healthy adult individuals categorized into four distinct groups based on their physical activity habits and fitness characteristics. These groups include: Aerobically Trained Individuals Participants actively engaged in aerobic exercise training (e.g., running, cycling, swimming) for at least two years. Likely to have higher cardiovascular fitness and endurance levels compared to other groups. Strength-Trained Individuals Participants actively engaged in regular weight training or resistance exercises. Expected to exhibit higher levels of muscle strength and hypertrophy. Non-Training Individuals Participants who are not engaged in regular aerobic or weight training exercises. Represent a baseline or control group with typical sedentary or minimally active lifestyles. Highly Flexible Individuals Participants identified by achieving high scores on flexibility assessments, regardless of their training status. Expected to have greater joint range of mot

You may qualify if:

• Group 1 (Aerobically Trained)
• years old
• actively training or competing over the past 2 years
• or more days of vigorous activity accumulating approximately least 1500 MET min/week or 7 days of any combination of walking, moderate, or vigorous intense activities achieving a minimum of 3000 MET min/week
• Group 2 (Strength trained)
• years old
• actively training or competing over the past 2 years
• or more days of muscle-strengthening exercise at an intensity of approximately 5 out of 10
• Group 3 (Not actively training)
• years old
• actively training or competing over the past 2 years
• or more days of muscle-strengthening exercise at an intensity of approximately 5 out of 10
• Group 5 (High flexibility)
• years old
• Sit-and-reach performance is categorized as "very good" or excellent based on the American College of Sports Medicine's sit-and-reach evaluation criteria (Table 4.16 of ACSM's Guidelines for Exercise Testing and Prescription 9th edition).

You may not qualify if:

• History of cardiovascular disease (Cardiac, peripheral vascular, or cerebrovascular disease)
• History of stable or unstable angina
• History of cardiac dysrhythmias causing symptoms or hemodynamic consequences
• History of hypertrophic cardiomyopathy
• History of cardiac valvular disease (e.g., aortic stenosis)
• History of pulmonary disease (Chronic obstructive pulmonary disease, asthma, interstitial lung disease, or cystic fibrosis)
• History of pulmonary embolus
• History of suspected or known aneurysm
• History of metabolic disease (Diabetes mellitus (type I or II), thyroid disorders, renal or liver disease
• History of renal disease
• History of neuromotor, musculoskeletal, or rheumatoid disorders that are exacerbated by exercise
• Current acute systemic infection, accompanied by fever and body aches.
• Pain or discomfort in the chest, neck, jaw, arms, or other areas that may be due to myocardial ischemia (lack of adequate circulation)
• Shortness of breath at rest, during daily activities, or with mild exertion
• Dizziness or syncope (fainting)
