The exercises found to produce 4G's were running faster than a 10-minute mile and jumping up and down off a 15-inch high box. These 4G impacts were important even though they were rare occurrences in the study. The study also looked at older adults and found 4G forces were nonexistent in the subjects studied.
If you are unable to run or jump because of injury or pain don't give up hope. Most injuries and pain are caused by postural imbalances that cause faulty joint position and movement patterns and can be corrected. Seeing an Advanced Exercise Therapist and Postural Alignment Specialist will be able to help significantly. The AET or PAS will be able to identify your postural imbalances and inefficient movement patterns and lead your through a program of specific corrective exercises to restore proper muscle engagement and joint position. These postural improvements will allow your injuries to heal, pain to decrease, and allow you to start introducing bone building exercises into your routine.
