Analysis of the hip, knee and ankle joints involved in rowing
Oarsmen, in the off-season, frequently use the Concept 2 rowing ergometer to train for the dynamic movement of rowing. There are many variations among athletes’ of different skill levels joint range of motion while using this machine.The first part of the stroke is the catch, when the rower sits with knees in flexion, slightly rotated about their hips, with their back and arms straight, poised to accept the premier driving force of the legs (Figure 1.1). Subsequently, the drive begins sequentially, commencing with the extension of the knees, followed by a swinging hip extension of the back, lastly finished off by flexion of the arms about the elbow (figure 1.2-1.4). Finally, as the rower sits with their knees…show more content… A tape measure, which marked 2.3 meters, rest below and parallel to the rowing machine. Contrasting markers were placed on key anatomical landmarks: the styloid process and olecranon of the ulna, the lateral epicondyle and greater trochanter of the femur, and the anterior superior iliac spine. Prior to undergoing an in-depth analysis, the ranges of motion about the hip, knee, and elbow were quantified using DartFish.
Differences were present between the proficient and novice rower in both their magnitude of joint excursion and the ratio between the recovery and drive stage of the stroke. The largest difference in joint excursion appeared in the hip joint (Figure 2 and Table 1). Visually, the differences in hip flexion, at the catch (Figure 3), and hip extension, at the finish (Figure 4), were clearly noticeable. In addition, a disparity between the ratios of the drive to the recovery portion of the stroke was present, with the proficient rower demonstrating a higher ratio compared to that of the novice rower (Table
