S M NAZMUZ SAKIB CARDIO-OPTIMIZED RHYTHMIC EXERCISE (SCORE): A HEARTBEAT-HARMONIC TRAINING PARADIGM FOR REAL-TIME SKELETAL–CARDIAC SYNCHRONIZATION
The S M Nazmuz Sakib Cardio-Optimized Rhythmic Exercise (SCORE) method introduces a novel paradigm in exercise science that synchronizes skeletal muscle movement cadence to the performer’s real-time cardiac rhythm via rational p : q harmonic ratios. Unlike conventional tempo training driven by fixed external beats, or heart-rate zone methods that regulate intensity without temporal coupling, SCORE dynamically adjusts movement cadence in direct proportion to instantaneous heart rate, preserving the chosen harmonic ratio throughout a session. Each concentric and eccentric phase is intentionally aligned to grouped heartbeat cycles, enabling biofeedback-driven, adaptive training that can enhance autonomic regulation, optimize venous return through muscle-pump synergy, and improve movement economy. Different ratio configurations allow targeted outcomes: slower ratios (p < q) for strength and time-under-tension, near-equal ratios (p ≈ q) for coordination and endurance, and faster ratios (p > q) for quickness and elasticity. SCORE requires only real-time heart rate monitoring and can be applied across a variety of movements without specialized equipment, making it accessible for athletes, rehabilitation settings, and general fitness. This approach establishes a distinct, testable organizing principle for synchronizing human movement with intrinsic cardiac timing.

S M NAZMUZ SAKIB ORTHOGONAL CONTROL THEORY(SOCT): APPLICATION IN BIOMECHANICS, PHYSIOTHERAPYAND REHABILITATION
This comprehensive review paper explores the clinical applications of the S M Nazmuz Sakib Orthogonal Control Theory (SOCT) in physiotherapy and rehabilitation sciences. SOCT provides a novel mathematical framework for analyzing human movement through three fundamental pillars: the Tendon-Induced Metric (TIM), Activation Pythagoras for Co-Contraction (APC), and Power-Activation-Excursion (PACE) inequality. We examine how this theory enables precise quantification of movement efficiency, co-contraction, and neuromuscular alignment in various clinical populations. Through detailed mathematical analysis and clinical case studies, we demonstrate SOCT’s applications in stroke rehabilitation, cerebral palsy management, sports injury recovery, and geriatric mobility enhancement. The theory offers transformative potential for personalized rehabilitation protocols, objective assessment metrics, and biofeedback systems. We also discuss integration with emerging technologies such as wearable sensors and machine learning, along with future research directions for clinical validation and implementation.
