Abstract

PURPOSE

To determine if the presence of observers affects muscular strength performance in college-age males and females.

METHODS

Twenty-five women and 24 men participated in the study. Two counter-balanced trials were performed in which participants completed 1-RM tests in bench press and leg press. During one trial, two members of the opposite gender observed the 1-RM tests. During the other trial there were no observers, other than the tester.

RESULTS

1-RM for females increased 3.4±0.8 lbs on bench press (p<.001) and increased 9.2±3.8 lbs on leg press (p=.025) when observers were present. 1-RM for males increased 4.2±1.1 lbs on bench press (p=.001) and increased 18.8±5.2 lbs on leg press (p=.002) with observers present. There was no difference in the percent increase in 1-RM between males and females for either leg press (p=.71) or bench press (p=.08).

CONCLUSION

College-age males and females lifted more weight during a 1-RM test when observers were present.

摘要

目的

确定观察者的存在是否会影响大学生年龄的男性和女性的肌肉力量表现。

方法

25名女性和24名男性参与了该研究。进行了两次平衡试验，参与者在卧推和腿举中完成1次最大重复量（1-RM）测试。在一次试验中，两名异性成员观察1-RM测试。在另一次试验中，除了测试者外没有其他观察者。

结果

当有观察者在场时，女性卧推的1-RM增加了3.4±0.8磅（p<0.001），腿举增加了9.2±3.8磅（p=0.025）。男性卧推的1-RM增加了4.2±1.1磅（p=0.001），腿举增加了18.8±5.2磅（p=0.002）。在腿举（p=0.71）或卧推（p=0.08）中，男性和女性1-RM的增加百分比没有差异。
