The Study
Influence of two different modes of resistance training in female subjects.
This study is like a small test where two groups tried different exercise plans. It shows that both plans might be linked to muscle growth and strength, but it can't prove one plan causes better results than the other because we don't know all the details of how the test was done.

For women who don't usually lift weights, doing lots of lighter reps or fewer heavy reps both build similar muscle size and make you stronger after two months.
For women new to weight training, doing either many lighter reps or fewer heavier reps for 8 weeks gives about the same muscle growth in the thigh muscles, showing both methods work well for beginners.
When women who haven't trained before do weightlifting for 8 weeks, they get much stronger (27-43% stronger) but their muscles don't grow much (only 3-4% bigger), showing that getting stronger happens faster than building bigger muscles at the start.
A study found that for women new to weightlifting, doing many reps with lighter weights or fewer reps with heavier weights both built muscle and strength equally well over 8 weeks.
