Resistance training and head-neck segment dynamic stabilization in male and female collegiate soccer players.

摘要: CONTEXT Cervical resistance training has been purported to aid in reducing the severity of brain injuries athletes. OBJECTIVE To determine effect an 8-week resistance-training program on head-neck segment dynamic stabilization male and female collegiate soccer players. DESIGN Pretest posttest control group design. SETTING University research laboratory fitness center. PATIENTS OR OTHER PARTICIPANTS Thirty-six National Collegiate Athletic Association Division I players (17 men, 19 women). INTERVENTION(S) The underwent cervical that consisted 3 sets 10 repetitions neck flexion extension at 55% 70% their 10-repetition maximum 2 times a week. Participants performed no exercises. MAIN OUTCOME MEASURE(S) Head-neck kinematics stiffness, electromyographic activity upper trapezius sternocleidomastoid muscles during force application head, flexor extensor isometric strength. RESULTS No kinematic, electromyographic, or stiffness effects were seen. strength was 15% greater than pretest measurement. Isometric 22.5% pretest. Women's girth increased 3.4% over time regardless level. Women exhibited 7% less length 26% mass men. CONCLUSIONS Despite increases girth, isotonic did not enhance Future researchers should examine protocols include traditional neuromuscular activities (eg, plyometrics) with focus head acceleration application.
