No previous studies have investigated a high-intensity interval
training program (HIIT) with an immersed ergocycle and Mediterranean diet
counseling (Med) in obese patients. We aimed to compare the effects of an
intensive lifestyle intervention, Med and HIIT with a water-immersed versus
dryland ergocycle, on cardiometabolic and exercise parameters in obese patients.
METHODS: We retrospectively identified 95 obese patients at their entry into a
9-month Med and HIIT program: 21 were trained on a water-immersed ergocycle and
74 on a standard dryland ergocycle. Body composition, cardiometabolic and
exercise parameters were measured before and after the program. RESULTS: For
obese patients performing water- and dryland-exercise (mean age 58+/-9 years
versus 55+/-7 years), BMI was higher for the water- than dryland-exercise group
(39.4+/-8.3kg/m(2) versus 34.7+/-5.1kg/m(2), P<0.05), and total fat mass, fasting
glycemia and triglycerides level were higher (P<0.05). Both groups showed
similarly improved body composition variables (body mass, waist circumference,
fat mass, P<0.001), fasting glycemia and triglycerides level (P<0.05). Initial
maximal aerobic capacity (metabolic equivalents [METs]) and maximal heart rate
(HRmax) were lower for the water- than dryland-exercise group (P<0.05). For both
groups, METs, resting HR, resting blood pressure, abdominal and leg muscle
endurance were similarly improved (P<0.05). CONCLUSIONS: A long-term
Mediterranean diet and HIIT program with water-cycling is as effective as a
dryland program in improving body composition, fasting glucose, triglycerides
level, blood pressure and fitness in obese patients. A Mediterranean diet
combined with water-cycling HIIT may be efficient for severely obese patients at
high risk of musculoskeletal conditions.
