Squatting Exercises in Older Adults: Kinematic and Kinetic Comparisons

摘要: Resistance exercise prescription is a diverse science used to improve sport performance, rehabilitate injury, and preserve functional independence in older adults. Despite its branching applicability, all resistance prescriptions require fundamental analysis, termed needs analysis. Needs analysis the process whereby clinicians, coaches, rehabilitation specialists analyze biomechanical requirements of an activity select exercises with similar motor recruitment patterns. Thus, appropriate requires both be improved, restored, or preserved that may these endeavors. The preservation physical growing concern within our society, receiving attention from geriatric educators, researchers, specialists. Walking, sitting rising chair, ascending descending stairs are important determinants independence; consequently, researchers using analyses better characterize activities. Gait has received comprehensive evaluation (30), although not as consolidated, there considerable information on (7), chair (22). The same level however, been conducted improve, maintain, restore movements. The squat functional, multiple-joint evaluation. Investigations have examined kinematics (20), kinetics (21), muscle patterns (17) at various joints (13) for different stances loads (5); investigations characterized parameters elders variations exercise. One such variation particularly applicable adults box squat. performed by squatting (i.e., lowering body’s center mass flexing hip knee joints, dorsiflexing ankle joints) onto stable surface box, bench, then standing position. Both (SQ) (CSQ) can home without specialized equipment, supervision, varying (e.g., elder participants use their BW additional wear resistance-adjustable weighted vest). Further, activities self-spotting techniques support themselves countertop while performing activities), CSQ especially because: 1) mimics chair; thus, it provide high degree transference this “activity daily living”; 2) increases safety providing seat event repetition cannot completed if participant becomes fatigued loses balance). Both SQ simultaneous coordination hip, knee, musculature, involve alternating concentric eccentric contractions groups. similarities, differences movement two during CSQ) likely invoke associated activities. The purpose investigation was compare contrast healthy, sample. We hypothesized outcome measures, (hip, peak joint flexion angles, extensor moments, power, work, impulse) would exist between movements. This generate profiles physicians, therapists, when designing safe efficient programs elders.
