“…Based on the propulsive force, F propulsive = m Total /a rowing , the average acceleration of 3.12 m/s 2 with the total mass of 88 kg (70 kg (Single rower) + 14 kg (Scull boat) + 4 kg (Oar and equipment)) produced 274 N force. This value is valid based on the estimated blade force ranging between 107-393 N as reported in the previous studies [25,36,44,47,55,56]. However, 274 N of blade force from the calculation is considered after 20 % energy loss, hence, before losses happen the initial blade force generated will be 308 N [24].…”

“…For the monitoring purposes on the ergometer, the load cell or strain gauge is mounted directly to the handle cord. Whereas for the oar, the strain gauge is mounted directly on an inboard shaft or ringer and the associated bending is corresponding to the force applied is captured [43][44][45][46]. The rower has a rapid increase in force during the stroke and moves the handle faster in the first half of the drive.…”

“…During the first half of the stroke, a great amount of the work is done on the blade, since it moves almost in a perpendicular direction with the boat by providing the boat thrust, which eventually displaces a large mass of water along the path [49]. According to the hydrodynamic equation, the magnitude of the force is the function of the relative velocity that is derived from the timing between the boat velocity and angular velocity of the oar despite the blade area, water density and lift or drag force coefficient [44].…”

According to numerous studies, rowing performance is influenced by several factors including rower’s biomechanics, rower’s physiology, the force generated and stroke style. However, there is a missing gap linking such factors with rowing performance in the available literature. This paper aims to investigate the rowing mechanism in terms of rower anthropometry and physiology, which can impact its biomechanics and performance. The corresponding hydrodynamic force generated by the oar blade to accelerate the boat is also considered in the current study. To test the objectives, systematical online searching was conducted in search of the inclusion literature criteria. All included studies used Preferred Reporting item for Systematic Review and Meta-analysis (PRISMA) guidelines to obtain the final collection of articles for this review. In order to rate the quality of the articles, risk bias assessment was performed. A total of 35 studies were included in the assessment. The studies discussed the aspects of anthropometry and physiological of the rower, the biomechanics of the rower, corresponding hydrodynamic force on the oar blade and the rowing mechanism concerning boat performance. Based on the information obtained, an understanding of the important aspects of the rowing mechanism was achieved to provide an update for comprehensive improvement.
