2. Monocular rotation (duction) of the eye toward the nose.
3. A position resulting from such movement. Compare: abduction.

The result of KAMs in cycling is not supported by findings from previous gait studies regarding the effect of knee alignments, which have shown that a static varus alignment is associated with a greater peak knee adduction angle and an increased KAM during walking in both healthy (Barrios et al., 2009; Barrios and Strotman, 2014; Stief et al., 2011) and knee OA populations (Hurwitz et al., 2002; Messier et al., 2014; Turcot et al., 2013).
This warm-up program consisted of light running, squatting, and hip adduction and abduction muscle activation [20].
There existed a significant linear relationship ([R.sup.2] > 0.70) between primary strength and the activation of muscles at secondary joint in each task, which indicated that muscles at secondary joint can be activated in primary strength task, especially TB, BR activation in shoulder abduction, BB, TB, BR activation in shoulder adduction, AD, MD, PD activation in elbow extension, and PM, AD, MD, PD activation in elbow flexion.
In adduction, the contracting belly of the medial rectus muscle is seen behind the eye with the thin tendon extension attached well anterior of the equator.
Such tests can be performed in various different positions, standing, sitting with or without back support clinical setting: for the abduction the patient was sitting on the table without back support, advised to keep a straight position; while for the rotations and the horizontal adduction he or she was respectively recumbent and lying on his or her side.
Table 3 shows the results for the first three pairs for all tests for baseline and emergent relations as well as the adduction test.
With respect to shoulder adduction, higher values of joint amplitude were observed after the sessions using an UP at 60% of 1RM (44.9 [+ or -] 10.2; P = 0.02) and 80% of 1RM (45.4 [+ or -] 12.9; P = 0.02) versus the pre-test (38.0 [+ or -] 13.7).

A closer examination of the two glottal adjustments revealed a causal relationship between (1) the singer's intended sound quality; (2) the muscular adjustments made in the larynx; (3) their impact on glottal adduction (membranous and/or cartilaginous glottis); (4) the vibratory properties of the vocal folds and their effect on glottal airflow; and (5) the actual sound that is being produced.
The maximum shear stress is 6.37E-4 MPa during adduction. At Medial side, the values of the shear stress ranging from -2.03 E-3 MPa to 2.06E-3 MPa.
Based on our case report, the mechanism for associated ankle and talar body fractures involves the adduction force of the supinated foot, which causes a shear fracture of the medial malleolus followed by an axial load on the dome of the talus.
