UNASSIGNED: The purpose of this study was to examine whether or not lower limb sprint interval training following arm resistance training influences training response of arm muscle strength and @entity1184 . Twenty @entity1 participated in this study. We divided subjects into @entity3013 ( @entity3013 , n=6) and concurrent training group (CT, n=6). The @entity3013 program was designed to induce muscular @entity1184 (3 sets x 10 repetitions (reps) at 80% 1 repetition maximum [1RM] of arm curl exercise), and was performed in an 8-week training schedule carried out 3 times per week on nonconsecutive days. Subjects assigned to the CT group performed identical protocols as strength training (ST) and modified sprint interval training (4 sets of 30-s maximal effort, separated in 4m 30-s rest intervals) on the same day. Pre- and post-test maximal @entity26 consumption (VO2max), muscle cross-sectional area ( @entity10002 ), and 1RM were measured. Significant increase in VO2max from pre- to post-test was observed in the CT group (p=0.010, ES=1.84), but not in the @entity3013 group (p= 0.559, ES= 0.35). Significant increase in @entity10002 from pre- to post-test was observed in the @entity3013 group (p=0.030, ES=1.49), but not in the CT group (p= 0.110, ES= 1.01). Significant increase in 1RM from pre- to post-test was observed in the @entity3013 group (p= 0.021, ES= 1.57), but not in the CT group (p= 0.065, ES= 1.19). In conclusion, our data indicate that concurrent lower limb sprint interval training interfere with arm muscle @entity1184 and strength.
