Objective : To determine the level of neck strength decrement and the rate of strength recovery of the neck muscles after a single bout of specific neck conditioning exercise in both males and females.

Hypothesis : A decrement in neck strength may be evident after a bout of strengthening exercise.

Design : Intervention study with pre-and-post design.

Setting : Biomechanics laboratory.

Participants : Twenty healthy participants (10 male and 10 female, mean ± standard deviation age 22 ± 1.2 years).

Main Outcome Measures : Participants performed a single bout of neck strengthening exercise. Neck strength testing using an isokinetic dynamometer was performed pre and at five time points (1 h, one, three, five and seven days) post-exercise to assess the level of neck strength decrement and neck strength recovery rate from pre-exercise levels.

Results : Statistically significant (p ≥ 0.036) decreases in neck extension strength were recorded in all participants 1 h and one day post-exercise. The level of neck extension strength returned to pre-exercise levels three days post-exercise and surpassed pre-exercise levels five and seven days post-exercise. The male participants' neck flexion strength decrement and recovery followed a similar pattern to that displayed in neck extension but more variability in neck flexion strength recovery rates were recorded in the female participants in this study.

Conclusion : The consistent strength recovery times for the male participants recorded in this study idealise the prescription of neck strengthening exercises in a periodised fashion. More investigation needs to be instigated for the female neck musculature as consistent strength recovery rates were not identified in this study.
