■这项研究旨在确定在卵泡早期和黄体早期,大腿和小腿肌肉肌腱单位的肌肉和肌腱刚度的变化,并检查每个阶段肌肉和肌腱刚度之间的可能关系。
■样本由15名月经周期规律的女大学生组成。基础体温法,排卵工具包,和唾液雌二醇浓度测量用于估计早期卵泡和早期黄体期。便携式数字触诊设备可测量卵泡早期和黄体早期的肌腱硬度。测量部位是股直肌(RF),中肌(VM),髌腱(PT),腓肠肌内侧头,比目鱼肌,和跟腱.
■在卵泡早期和黄体早期之间,大腿和小腿肌肉-肌腱单元刚度没有统计学上的显着差异。在黄体早期,RF和PT的刚度(r=0.608,p=0.016)与VM和PT之间(r=0.737,p=0.002)之间存在显着的正相关。
■目前的结果表明,在早期卵泡期和早期黄体期之间,大腿前部和小腿后部的腿部肌腱单元的刚度没有变化,并且肌腱可能在那些在黄体期早期大腿前部肌肉较硬的女性中更硬。
UNASSIGNED: This study aimed to determine changes in the muscle and tendon stiffness of the thigh and lower leg muscle-tendon units during the early follicular and early luteal phases, and check for possible relations between muscle and tendon stiffness in each phase.
UNASSIGNED: The sample consisted of 15 female university students with regular menstrual cycles. The basal body temperature method, ovulation kit, and salivary estradiol concentration measurement were used to estimate the early follicular and early luteal phases. A portable digital palpation device measured muscle-tendon stiffness in the early follicular and early luteal phases. The measurement sites were the rectus femoris (RF), vastus medialis (VM), patellar tendon (PT), medial head of gastrocnemius muscle, soleus muscle, and Achilles tendon.
UNASSIGNED: No statistically significant differences in the thigh and lower leg muscle-tendon unit stiffness were seen between the early follicular and early luteal phases. Significant positive correlations were found between the stiffness of the RF and PT (r = 0.608, p = 0.016) and between the VM and PT (r = 0.737, p = 0.002) during the early luteal phase.
UNASSIGNED: The present results suggest that the stiffness of leg muscle-tendon units of the anterior thigh and posterior lower leg do not change between the early follicular and early luteal phases and that tendons may be stiffer in those women who have stiffer anterior thigh muscles during the early luteal phase.
