Completing a systematic review on the analysis of muscle activity on the bench press, I have 15 studies and I have to find out whether they are Qualitative, quantitative (non-randomized), quantitative (descriptive), or mixed methods!
One example of a study summarized for you is:

14 (males).
Age = 22.5±2.4 years, height = 173.6±7.10cm, body mass = 76.03±9.02kg.
Experienced in resistance training for a least six months. |
To compare the EMG activity of the upper limb and shoulder girdle muscles in a resistance training session involving the pre activation method in stable and unstable conditions. |
Subjects performed 10 reps of stable or unstable dumbbell fly at 30% 1RM, and barbell bench press was executed at 60% of 1RM until concentric failure. The 1 RM test was performed for both exercises and, in case of dumbbell fly, on both surfaces. Two-way ANOVA for repeated measures indicated that the pre-activation method performed on both surfaces raised the EMG activity for all muscles. |
Pectoralis major, deltoid anterior, triceps brachii, serratus anterior |
No differences were observed between the stable and unstable conditions. These results indicate that the execution of a previous exercise increase cannot be attributed to the pre-activation method but rather to the completion of two consecutive exercises. |
