Training effects of combined resistance and proprioceptive neck muscle exercising

Abstract

Objectives:

To investigate training effects of two different resistance and proprioceptive exercising concepts of neck muscles.

Material and Method:

Twenty-six healthy women participated in a randomized pilot trial. The test persons were randomized to two different neck-training programs (resistance training (RT) and proprioceptive resistance training (PRT)). They performed a standardized training program for the duration of ten weeks two times weekly. The neck strength, the cross-sectional area of three neck muscle groups (1. sternocleidomastoid muscles; 2. multifidus and semispinalis cervicis muscles; 3. semispinalis capitis and splenius muscles) and the proprioceptive capability evaluated by the dynamic joint repositioning error (DJRE) of the head were assessed pre- and post-intervention.

Results:

Strength gain did not differ significantly between the two resistance training groups (PRT group: 8.2% to 29.3%; RT group: 1.4% to 19.8%). Change of hypertrophy of all neck muscle groups was significantly ( $\mathit{p}\mathrm{<}0.001$ to $\mathit{p}=0.013$ ) greater in the PRT group (18.9% to 32.3%) than in the RT group (1.5% to 12.9%). The DJRE deteriorated with 35% in the RT group and did not change in PRT group (−2.0%).

Conclusion:

In combination with resistance training, proprioceptive training led to a significantly higher muscle hypertrophy and didn’t effect a significant deterioration of the proprioceptive capability compared to isolated resistance training.
