12 Weeks of Water Aerobics at Various Intensities for Adults and Older Adults

Effects of 12-week Moderate-intensity vs High-intensity Water-aerobic Training on Physical Fitness, Cardiovascular Health, and Well-being in Adults and Older Adults

The objective of this clinical trial is to understand the best intensity to perform water aerobics with adults and older adults. The main questions it aims to answer are:

• Is water aerobics performed at high intensity better than water aerobics performed at moderate intensity?
• Is performing water aerobics for 12 weeks good for muscle strength, body composition (body weight, fat mass), lipid profile (triglycerides, cholesterol), blood pressure, and quality of life in adults and older adults?

Participants need:

• Perform water aerobics at high or moderate intensity, twice a week, 45 minutes per class, for 12 weeks
• Be evaluated in the week before starting the water aerobics program (week 0) and at the end week of the program (week 12) regarding muscle strength, body composition, lipid profile, blood pressure, and quality of life

It was hypothesized that independently of the level of intensity used, all variables would improve after water aerobics. It was also expected to observe more gains in all parameters in high-intensity water aerobics compared to moderate intensity
