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 (p< 0.001 to 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.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
