简要总结
This goal of this clinical trial is to verify the best way to do water aerobics with adults and older adults. It wants to answer these questions:
- Is high-intensity water aerobics better than water aerobics performed at moderate intensity?
- Does a 24-week water aerobics program improve muscle strength, body weight, fat mass, triglycerides, cholesterol, blood pressure, and quality of life for adults and older adults?
Participants must:
- Do water aerobics at high or moderate intensity, twice a week for 45 minutes per class, for 24 weeks.
- Be assessed before starting the water aerobics program and after it ends to see if there are gains in muscle strength, body weight, fat mass, triglycerides, cholesterol, blood pressure, and quality of life.
It was believed that all variables would get better after doing water aerobics, no matter the intensity. It was also expected that doing higher-intensity water aerobics would lead to larger gains in all measurements compared to moderate-intensity.

结局指标
主要结局
Change from Baseline in body mass at 24 weeks
时间窗: Baseline and week 25
A bioimpedance balance was used for this test, with participants being barefoot and dressed in minimal clothing.
Change from Baseline in fat mass percentage at 24 weeks
时间窗: Baseline and week 25
Change from Baseline in fat-free mass at 24 weeks
时间窗: Baseline and week 25
Change from Baseline in body mass index at 24 weeks
时间窗: Baseline and week 25
The body mass index (BMI) was calculated by dividing the body mass value by the height squared (kg/m\^2). For this, each participant's height was measured using a precision stadiometer with a scale of 0.001 m. For the correct extraction of this test, participants were barefoot.
Change from Baseline in triglycerides at 24 weeks
时间窗: Baseline and week 25
Blood samples were collected before exercise (after a 15-minute rest period) and at least 2 hours after the last meal.
Change from Baseline in total cholesterol at 24 weeks
时间窗: Baseline and week 25
Change from Baseline in explosive strength of upper limbs at 24 weeks
时间窗: Baseline and week 25
The explosive strength of the upper limbs was measured by having participants throw a 3-kilogram medicine ball, with the best scores achieved by throwing the ball as far as possible. Three throws were performed, and the mean value was used in this test.
Change from Baseline in endurance strength of lower limbs at 24 weeks
时间窗: Baseline and week 25
The chair stand test was used to evaluate the endurance strength of the lower limbs. Participants sat in the center of a chair with a straight back and feet shoulder-width apart and in full contact with the floor. They then rose to maximum extension and returned to the initial sitting position, aiming to complete as many repetitions as possible within a 30-second.
Change from Baseline in diastolic blood pressure at 24 weeks
时间窗: Baseline and week 25
The automatic blood pressure monitor was used to measure the participants' blood pressure after seated and rested for 20 minutes.
Change from Baseline in systolic blood pressure at 24 weeks
时间窗: Baseline and week 25
Change from Baseline in endurance strength of upper limbs at 24 weeks
时间窗: Baseline and week 25
The arm curl test assessed the upper limbs' endurance strength. Participants were seated in a chair with a straight back and their feet flat on the floor, holding a 2 kg dumbbell in their dominant hand. They were instructed to perform as many correct flexions as possible within a 30-second time limit.
Change from Baseline in resting heart rate at 24 weeks
时间窗: Baseline and week 25
Resting heart rate was assessed using an automatic blood pressure monitor, after the participant was seated and resting for at least 20 minutes.
Change from Baseline in explosive strength of lower limbs at 24 weeks
时间窗: Baseline and week 25
The countermovement jump was used to assess the explosive strength of the lower limbs. Participants were instructed to perform three countermovement jumps, aiming to jump as high as possible, with one minute of rest between each jump. A higher jump height indicates a better score in this evaluation. The mean value of the three jumps was considered for the test.
次要结局
- Change from Baseline in quality of life at 24 weeks(Baseline and week 25)
