Exercise Training with Fitness Zone Equipment in Sedentary Hispanic Women

A Pilot Study

Abstract

Background and Purpose: Limited access to physical activity resources contributes to elevated prevalence of obesity in Hispanic women living in low-income urban Los Angeles neighborhoods. Purpose: The purpose of this study was to determine the benefits of training with fitness zone equipment recently made available in public parks. Methods: Six overweight, sedentary Hispanic women completed a 6-week combined resistance and cardiorespiratory training program. General health, muscular fitness (repetitions-to-fatigue), and cardiorespiratory fitness (one-mile walk), were assessed pre- and post-training. Results: Training significantly decreased weight (- 3.5±0.5 lbs.), body fat percentage (-2.1±0.9%), waist circumference (-1.3±0.2 cm), and increased muscular endurance repetitions (squats: 23.4±8.2, push-ups: 12.8±1.8, curl-ups: 13.0±3.3, leg presses: 62.7±15.5, right leg extensions: 18.2±5.6, left leg extensions: 18.5±5.6, chest presses: 20.8±5.4, lateral pull downs: 15.8±3.8, and vertical presses: 5.6±1.2 reps); p < 0.05. No change in VO2max was detected; p > 0.05. Conclusion: Fitness zone training, for which equipment is freely available at parks, may lead to health and fitness benefits for sedentary women in the initial stages of a weight loss program. Additional muscular strength, cardiorespiratory endurance, and associated health benefits are limited due to the mechanical design and nonadjustable nature of the outdoor equipment.
