TY - JOUR T1 - The Effect of Endurance Training on the Dynamic and Static Back Extensor Muscles TT - بررسی تاثیر تمرین‌های استقامتی روی استقامت دینامیک و استاتیک عضلات پشتی JF - RJMS JO - RJMS VL - 12 IS - 45 UR - http://rjms.iums.ac.ir/article-1-438-en.html Y1 - 2005 SP - 125 EP - 132 KW - 1) Dynamic Endurance 2) Static Endurance 3) Back Extensor Muscles 4) Endurance Exercise N2 -  The objective of the present study was to examine the effect of endurance exercises on static and dynamic endurance of back extensor muscles in two genders. This study with quasi-experimental repeated measure design was conducted on 20 men and 20 women as non convenience sampling. Dynamic and static back extensor tests were used for endurance measurement and following exercises, repeated measurement was done after the 5th and 10th sessions. A significant difference was found between 1st and 10th session in two groups but static and dynamic endurance had no difference in two groups. These results suggest that muscle endurance is the same in two genders and the affected pattern is similar in two groups. M3 ER -
