The purpose of this study was to evaluate if different types, body positions, and levels of progression of functional coordination exercises can provide sufficiently high levels of muscle activity to improve strength of the neck, shoulder, and trunk muscles. Nine untrained women were familiarized with 7 functional coordination exercises 12 times during 4 weeks before testing. Surface electromyographic (EMG) activity was obtained from rectus abdominus, erector spinae, obliquus externus, and trapezius during the exercises with 2-4 levels of progression. Electromyography was normalized to the maximal EMG activity during maximal voluntary contractions, and a p value < 0.05 was considered significant. All recorded muscles reached sufficiently high levels of activity during the coordination exercises for strength gain (>60% of maximal EMG activity). Type of exercise played a significant role for the attained muscle activity. Body position during the exercises was important for the activity of the erector spinae, and level of progression was important for the activity of the trapezius. The findings indicate that depending on type, body position, and level of progression, functional coordination training can be performed with a muscle activity sufficient for strength gain. Functional coordination training may therefore be a good choice for prevention or rehabilitation of musculoskeletal pain or injury in the neck, shoulder, or trunk muscles.
本研究旨在评估不同类型、体位和功能协调练习进展水平是否能提供足够高的肌肉活动水平，从而增强颈部、肩部和躯干肌肉的力量。9 名未经训练的女性在测试前的 4 周内，熟悉了 7 种功能协调练习，共 12 次。在练习过程中，使用 2-4 个进展水平，从腹直肌、竖脊肌、外斜肌和斜方肌中获得表面肌电图（EMG）活动。将肌电图与最大随意收缩时的最大 EMG 活动进行归一化，p 值<0.05 被认为具有统计学意义。所有记录的肌肉在协调练习中都达到了足够高的活动水平，以实现力量增长（>最大 EMG 活动的 60%）。练习的类型对肌肉活动有显著影响。练习时的体位对竖脊肌的活动很重要，而进展水平对斜方肌的活动很重要。研究结果表明，根据类型、体位和进展水平，功能协调训练可以达到足够的肌肉活动水平，从而实现力量增长。因此，功能协调训练可能是预防或康复颈部、肩部或躯干肌肉骨骼疼痛或损伤的一个很好的选择。
