This was an interesting study done in premenopausal women, ages 20 - 35 years old, during a 26 week long investigation. Three groups were used, a resistance training group, step-aerobics high impact group, and a control group.
The resistance training group completed a strength training routine at 65-80% of their 1RM, 3 times per week using the following exercises: leg press, back squat, leg extension, leg flexion, seated calf, standing calf, back extension and abdominal curl.
The step-aerobic high impact group performed a traditional step aerobics routine to music. After a 6 week familiarization period, subjects incorporated two legged landings (with an aerial phase). The number of landings increased from 50/session in week 7 to an average of 100/session in weeks 12-26.
