SMART WEARABLE SYSTEMS DEVICES FOR PHYSICAL FITNESS

Abstract

In this paper, we describe wearable technology. Wearable technology has revolutionized health and fitness monitoring by providing real-time tracking of physiological parameters. This paper reviews various wearable systems, including smart watches (SM), fitness trackers, smart clothing and biosensors, highlighting their applications in health monitoring, physical activity tracking, chronic disease management, and rehabilitation. It discusses the technological advancements, challenges, and future prospects of wearable health and fitness systems. Smart devices, such as smart watches and fitness bands, are widely used to monitor cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition, leveraging sensors for heart rate, motion, and bio impedance, alongside AI-driven insights. These devices offer accessible fitness tracking but face significant limitations that hinder inclusivity across diverse populations. Despite their popularity, technical limitations undermine their inclusivity for diverse populations. Optical heart rate and bio impedance sensors falter with darker skin tones, tattoos, or hormonal fluctuations, yielding inaccurate data for older adults (56+), females, and non-binary/transgender users on hormone therapy. Motion sensors misinterpret movements for disabled users with tremors or limb differences, skewing strength and endurance metrics. The review also explores issues related to data accuracy, privacy, and user acceptance.
