THE EFFECTS OF STRENGTH VERSUS COMBINED STRENGTH AND CARDIOVASCULAR TRAINING IN UNTRAINED WOMEN POLICE OFFICERS
JAMES M. SAYIH, 911 FITNESS, INC, MIAMI, FL, 33015
The purpose of this study was to identify and compare the strength and body composition changes elicited by 4 repetition maximum (RM) at 85% intensity and a combined cardiovascular with 4RM at 85% intensity protocols in untrained Women Police Officers. Twelve ‘Police Women’ volunteered to participate and were assigned to either the ‘strength group’ (M) or the ‘combined group’ (C). Training was performed 6 times per week for group C and 3 times for group M; free weights and machine equipment were used for both groups. Group C performed 6 sets of 4 repetitions at 85% of their 1RM and included thirty minutes of cardiovascular work on three alternating days of weight training. Group M performed 6 sets of 4 repetitions at 85% of their 1RM without cardiovascular work. Strength and body composition (3 site: skinfold with calipers–Tricep, Suprailiac, Thigh) was measured at 0 and 6 weeks. Significant increases in strength were observed in group M of 165% and group C of 118% at 1RM. Body composition occurred in both groups. The C and M groups loading intensities elicited significant and equal increases in strength and lean muscle tissue. Group M however showed 40% more strength than group C. These results suggest that strength training protocols produce more strength than combined strength/cardiovascular training over a 6 week period in previously untrained Police Women.
