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 clarify physical characteristics related to low back pain (LBP) in collegiate track and field athletes. We particularly focused on the nature of the track and field. The subjects were 21 male collegiate track and field athletes including only sprinters, hurdlers, long jumpers and triple jumpers. The examined parameters were physical characteristics, isokinetic flexor and extensor strength in the knee and trunk regions. The evaluation of LBP was estimated by a questionnaire test and orthopedic surgeons' diagnosis. According to these evaluations, we divided all track and field athletes into two groups ; LBP group (n=11, 52.4%) and no LBP group (n=10, 47.6%). As a result, a take-off leg of knee flexor/extensor strength ratio in the LBP group was significantly lower than that in the no LBP group (P<0.05). The LBP group showed a significant difference between a take-off leg and a lead leg in knee flexor strength compared with the no LBP group (P<0.05). The LBP group has been short engaged in the track and field than the no LBP group (P<0.05). In the trunk flexor and extensor strength, there was no significant difference between the LBP and the no LBP group in this study. These results suggest that the imbalanced knee muscle strength may be one of some factors related to chronic low back pain in collegiate track and field athletes.

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.
