In general, and with no consideration as to the impact of other concurrent training goals, strength is built using loads of 85% of 1RM and greater using a rep range of 2-5 reps per set for up to 8 sets or so, depending on your training level. Mass is built with lighter loads using a rep range of 6-10, going within a 1-3 reps of failure on each set.
To train both concurrently, you can choose an intermediate load and do something like a 5 x 5 scheme, or you can train each seperately, first doing something like 4-6 x 2 (work up to at least 85% for the last set or two) followed by 3-4 sets x 8-10, to work mass. If you are a sprinter, consider doing these during off season or early GPP. Again, this type of rep scheme works best ‘in general’ and may have to be modified when integrated into your overall training plan.
In termsof a phsiological response, it depends on what response your interested in. CNS stimulus? Hypertrophy? Motor unit recruitment?
