Vertical jump activity is a measurement of an athlete for different movements in sports required jumping. The analysis of this activity is subject to athlete’s capability to Drop Vertical Jump (DVJ) landing upon achieved optimal Vertical Jump Height (VJH). This article discusses applying smart sensing mechanisms for DVJ and VJH as assistive tools to analyze DVJ and VJH and provides biofeedback for athlete during DVJ for safe landing and VJH to reach desired target. While optimization of VJH is the primary target of any sport, DVJ causes injuries on lower extremity. Hence, appropriate vibrotactile feedback during DVJ allows injury prevention and smart watches as IoTs can be used for biofeedback visualization during VJH monitoring for performance enhancement. Thus, different smart sensing mechanisms are required to analyze lower extremity kinematics jointly with the influence of muscles during DVJ and VJH. In this research, Inertia Measurement Units (IMUs), vibrotactors, Qualisys Motion Capture System and Bio-capture system consisted of muscle activity measurement sensors are integrated for DVJ and VJH measurements. The overall system design presented allows athletes to customize and to re-configure for different sport regimes requirements involving different DVJ and VJH. Integrated low powered wearable IMUs, bio-capture system, vibrotactors and smart watch are cost effective and require little infrastructure with no influence on natural human movement due to their total weight less than 500 g. This chapter will give a comprehensive system architecture of wearable embedded devices for DVJ and VJH measurements and for biofeedback during DVJ and VJH.
