Muscular fatigue and its effects on weight perception

摘要: Abstract The objective of this study was to investigate how muscular fatigue affects the human's perception weights. main goal test hypothesis that weight is different if muscle fatigued than it not. Forty subjects (20 males and 20 females) between ages 18 30 yr participated in experiment. A set weights made from plastic containers filled with lead shots. weighed 50 500 g increments 50 g resulting ten variable Subjects were tested, before after training, on use Borg's RPE scale. results showed able learn scale only two training sessions. Next, asked exert maintain a maximum push-down force right arm until fatigued. Immediately fatigue, had lift both left arms simultaneously compare (variable weight) one (constant rate same process followed without fatiguing arm. when muscles not fatigued, values coincided well tested weight, such as represented number 10, 1 However, significantly lower. perceived be about 17% less. Relevance industry Muscular can impair proper weight. This may less needed hold, carry, or push an object, possibly accident.
