A study was conducted to evaluate and compare neck muscle strength between two levels of college American football players with the aim of preventing neck injuries. The subjects were American football players at N University (n=52) belonging to the first level league and American football players at G University (n=14) belonging to the third level league. The findings were as follows.1. The neck muscle strength of freshman players at N University tended to be lower than that of senior players.2. It was shown that the neck muscle strength/body weight of experienced American football players was 10-30% higher than that of inexperienced players.3. There was a significant difference in neck muscle strength/body weight between N University and G University in 1997. However, there was no significant difference between them in 1998, because neck muscle strength/body weight of G University players increased by 13-30% after neck muscle training for about nine months. It was suggested that coaching staff must evaluate the neck muscle strength of each player, especially in freshmen who have had no experience of American football, in order to prevent neck injuries because mismatch of performance level may cause catastrophic neck injury.

The purpose of this study was to examine the effects of dynamic neck muscle training using a cervical extension machine (CEM) on isometric cervical extension strength (ICES) and a cross-sectional area of neck extensor muscles. Subjects were 18 male college judo athletes divided into a control group (n=10) and training group (n=8), respectively. In the training group, dynamic neck muscle training was performed for a 6 week training period, followed by a 10 week training period. There was a detraining period of 12 weeks between the first training period and the second. The ICES was measured at eight angles using a CEM, and the neck muscle cross-sectional area was determined using magnetic resonance imaging. The ICES and cross-sectional area of neck extensor muscles in the training group showed significant increases after the second training period. In particular, the increase in the cross-sectional area was greater in the deepest layer of the neck extensor muscles (rotator, multifidus and semispinaris cervicis muscles) than in the superficial layer (trapezius muscle). In the control group, no significant changes in ICES or cross-sectional area were observed. In conclusion, it was shown that dynamic neck muscle training using a CEM was effective in developing both ICES and the cross-sectional area of neck extensor muscles, especially in the deepest layer.
