**Ref.** & **Commercial WT** & **Participants Age (Year)** & **Performance Metrics** & **Outputs/Conclusion** \\ \hline
[123] & MOTUS & 17 libasell Pitcher (9-12) & Medial elbow torque, arm speed, shoulder rotation & A relationship has been identified between increased medial elbow torque and ball velocity in young baseball pitchers. \\ \hline
[9] & MOTUS & 10 collegiate/ pro-level baseball pitcher (23) & arm slot, arm speed, arm stress, and shoulder rotation & MotusBASEBALL has been mentioned as a low-cost and partial alternative that is suitable for performing a complete biomechanical capture. \\ \hline
[96] & KINEXON & 44 ice hockey players (20 \(\pm\) 1.4 and 21.9 \(\pm\) 1.1) & Standing distance, speed and acceleration, turns, changes of direction (CoL), skating transitions & KINEXON LTS has been reported to provide reliable and accurate information for monitoring and assessing external loads on ice hockey players on the ice surface. \\ \hline
[124] & KINEXON & 27 male varsity ice hockey player (22.1 \(\pm\) 1.1) & Rating of Perceived Exertion (RFE), heart rate (HR) & KINEXON LTS has been reported to provide reliable and accurate information for monitoring and assessing external loads on ice hockey players on the ice surface. \\ \hline
[125] & CATAPULT OPTIVEYS & 28 female cricket pace bowlers (24 \(\pm\) 5.1) & Distance and velocity & There was a significant association of absolute ball velocity with maximum velocity during the delivery stride, peak resultant acceleration, run-up distance, and peak roll. \\ \hline
[126] & POLAR TEAM & 20 elite male field hockey players (21.2 \(\pm\) 2.4) & Total distance, high-intensity-running distance, spring distance, accelerations load & It has been reported that performance parameters (total distance, high-intensity running distance, spring distance) are higher in matches compared to training periods. \\ \hline
[127] & ZEPP COLF & 20 ICA-handapolge golfers (37 \(\pm\) 13 years) & Cluphead speed & The results suggest that Zep Golf 2 can only deliver accurate cubhead speeds on average across multiples, shots but not for individual shots. \\ \hline
[128] & ZEPP COLF & 7 intermediate to highly skilled male goller (23.8 \(\pm\) 4.5) & Cluphead speed & The magnitudes of frontal plane moments are greater than those previously reported, potentially indicating differing swing mechanics compared to this study, resulting in altered kinetics of the lower limbs during the golf swing. \\ \hline
[129] & THE MYO ARMBAND & 6 expert male table tennis players (17.8 \(\pm\) 1.2) & NA & The developed system can provide useful information for measuring the expert-novice differences in firewhand loop skills. \\ \hline
[122] & XSENS & 29 tennis players (21.8 \(\pm\) 6) & Joint angles of shoulder, elbow, wrist separation angle, hip, knee, and ankle & It can be concluded that it can provide excellent measurements for most joint angles during the firewhand stroke, offering an advantage for data collection without the need for a limited calibrated area and the possibility of collecting data outdoors without pointer occlusion. \\ \hline \hline \end{tabular}
