Table 1 Intervention group exercise program

From: Effect of supervised exercise in groups on psychological well-being among pregnant women at risk of depression (the EWE Study): study protocol for a randomized controlled trial

Duration Intervention Description of exercise Load
10 minutes Warm-up Up to each teacher Has to include: • Light cardiovascular exercise • Mobilization of shoulder/back/pelvis Examples: Neck stretching: standing in a circle, perform shoulder rotations and elevations Exercise of low intensity Walking in a circle: forward, backward, and sideways Shoulder/spine/pelvic mobility 1. Arm swings (one arm + both arms) 2. Arm swings in a kayak-paddling motion 3. Lateral flexions 4. Pelvic tilts (anterior, posterior, bilateral, figure eights) 5. On all fours, flexion/extension of the spine to find the neutral position Borg Scale 7–10
20 minutes Endurance training Exercise bikes, treadmills, or cross-trainers Borg Scale 11–15
25 minutes Strength training Pelvic floor 1. On all fours: elevation of the extremities to engage the back and hamstrings; diagonal lift, 3 × 10 repetitions followed by a 10-second isometric hold; there is a short break after each isometric hold 2. Supine position: upper extremity flexion/extension to strengthen the upper arms and pectoral muscles; 3 × 10 repetitions; 60-second break after each of the three sets 3. Squats: strengthening of the thighs and gluteal muscles; 3 × 12 repetitions; 60-second break after each of the three sets Supine position (or side-lying position if preferred) 1. Short muscle squeeze × 10 2. Squeeze held for 6–8 seconds × 20 with a 6- to 8-second break between each squeeze 3. Squeeze held for 30 seconds × 2 with a 15-second break between each squeeze 60–70% of one-repetition maximum endurance
15 minutes Stretching and relaxation Up to each teacher Has to include: • Breathing exercises • Relaxation • Stretching Example: Relaxation compact disc or verbal guiding with emphasis on breathing; approximately 5 minutes Stretching of the big muscle groups: • Pectoralis major • Gluteus maximus • Quadriceps • Triceps surae Borg Scale 6
