The distribution of type-I and type-II fibers in 9 different parts of the musculi triceps brachii, longissimus dorsi, gluteus medius, and biceps femoris was studied to determine whether biopsies from these muscles give reliable information. All 4 investigated muscles were not homogeneous in their fiber-type distribution. Large differences existed among different muscle parts. The percentage of type-I fibers increased toward the deeper and cranial parts of the muscles. In the same zone of the gluteus muscle, differences of 30% were found for type-I fibers. Therefore, results obtained by biopsies of muscles must be interpreted with caution.
研究了肱三头肌、背最长肌、臀中肌和股二头肌9个不同部位的I型和II型纤维分布，以确定取自这些肌肉的活检是否能提供可靠信息。所有4块被研究的肌肉在纤维类型分布上都不均匀。不同肌肉部位之间存在很大差异。I型纤维的百分比朝着肌肉更深和更靠近头侧的部位增加。在臀肌的同一区域，I型纤维的差异达30%。因此，对肌肉活检获得的结果必须谨慎解读。
