重量訓練是增進肌肉的力量及尺寸最普遍訓練的方法。要讓肌肉成長的四個基本流程是: 1.針對性 2.負重 3.休息 4.加重。尤其休息期間，讓撕裂的肌肉纖維重建及成長是相當重要的一部分
本實驗針對肌肉肥大以及肌耐力訓練，我們在觀察訓練對於肌肉的反應於 訓練前、訓練後以及訓練的24、48、72小時候之後。
本實驗找了兩個族群的受試者，分別是:一般族群以及健身愛好者。欲探討不同的族群在訓練方法這兩種訓練方法上是否造成身體影響的異同。延遲性肌肉痠痛(DOMS)、最大自主等長收縮(MVC)、最大反覆性動態收縮(1-RM) 將用以評估力量。實驗結果顯示，不同的訓練方法影響DOMS於各個族群。於MVC和1-RM上，對於健身愛好者與一般族群之間沒有顯著的變化。

Weight training is the most common approach to develop the strength and size of our muscles. The training program consists of 4 basic principles: specificity, overload, recovery and progress. Particularly, the recovery after exercise is an essential part for muscle tissue repairing and rebuilding. To observe the body effects of pre-training, post-training, 24, 48 and 72 hours after training, this work performed hypertrophy and endurance training.
This work additionally recruited two types of subjects, normal subjects and gym enthusiasts, to discover whether the body effects will be different on conditions of subject’s skeletal muscles. The delayed onset muscle sourness (DOMS), maximum voluntary contraction (MVC) and one-repetition maximum (1-RM) strength were measured for effect evaluation.
Experimental evidence shows that different type of training affects the DOMS’s level on both groups. However there’s no significant difference between MVC and 1-RM measured from normal subjects and gym enthusiasts.
