Objective: The goals of this study were to investigate and compare the effects of aerobic and spinal stabilization training on the knee muscle hamstring-to-quadriceps (H/Q) ratio in adult women.   Methods: Seventy of 85 women who applied to the fitness center were randomly assigned to spinal stabilization or aerobic training groups (1, 2). Twenty-one women out of 35 sedentary women from the university who had not participated to any sport or exercise program were followed as controls. The training programs were conducted for 3 days/week for six months. All subjects were assessed before training, at the 3rd, and 6th month of training. Assessments were performed with the Isomed 2000 isokinetic system (D&R Ferstl GmbH, Hemau, Germany). The peak torque and total work of H/Q ratios were calculated. Repeated measures and the “as treated” protocol (spinal stabilization (n=28), aerobic training (n=23)) were used for the analysis.   Results: The hamstring-to-quadriceps ratio of peak torques on the dominant side increased between pre-training (0.732±0.12) and the 6th month of training (0.847±0.11) in the aerobic training group (F=6.08; p=0.03). The H/Q ratio of the total work increased on the dominant side in the stabilization training group between pre-training (0.773±0.15) and the 3rd month (0.855±0.12), (F=6.402; p=0.002) of training. It increased pre-training (0.707±0.17) and in the 6th month of training (0.777±0.13) in aerobic training group.   Conclusion: Both aerobic and stabilization trainings improved the total work of the H/Q ratio. Stabilization training could be recommended for prompt improvement of the H/Q ratio for sedentary women.
