Hypertrophy is the cause of the strength deficit, actually.
Ideally, any form of power and/or explosiveness training will work to reduce this factor; Anything from ballistic reps at 55-65% of your max to heavy singles at 90-95% of your max will work.
Main criteria is to 1) make your training regimen use low reps, 3-5 or less, with either high acceleration of low weights or attempted acceleration of heavier weights, 2) contrast the means as much as possible. For example, alternate light ballistic reps with maximal reps. 3) Keep the total number of lifts (NL) close to the following guidelines: 50-70% - 24, 70-80% - 18, 80-90 - 15, 90+ - 7
Depending on your personal capabilities, anywhere from 2-5 sessions per week by lift are possible.
