Does training with partial reps build muscle and strength like full reps?
Effects of final partial range of motion vs. full range of motion resistance training on muscle adaptations in physically active young men: a within-subject study

Two groups of guys trained their arms and legs: one used full movements, the other used partial movements at the end of each rep. Both trained the same amount, same weight, same frequency.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When trained people lift weights using either a partial range of motion at long muscle lengths or a full range of motion, and both methods use the same total workload and effort, the amount of muscle growth is the same.
In physically active young men, resistance training using a limited range of motion results in similar maximal strength gains after six weeks as training using a full range of motion, with no statistically detectable difference between the two methods.
In physically active young men, six weeks of resistance training three times per week at 60% of one-repetition maximum produces the same increases in muscle size and strength whether using full range of motion or partial range of motion.
In physically active young men, six weeks of resistance training using a partial range of motion results in the same amount of muscle growth in the biceps and quadriceps as training with a full range of motion.
When you do exercises that stretch your muscles more through a bigger movement—like doing full squats instead of tiny half-squats—you may build more muscle tissue than when you stay in a shorter, more restricted movement range.
