Purpose: This study was aimed at determining whether short-term (4 weeks) different types of weight loss training programs in middle-aged individuals after the application make changes in the entire body and regional body composition, whether there is a more effective program and whether there is a difference between the sexes. Method: Twenty-six middle-aged (44 ± 7 years old), obese and non-active women and men were randomly divided into four groups: the non-specific training program (G1), the combined resistance and resilience program (G2), the combined resistance and resilience program (G3) and the non-nutrition training program (G4). The body mass of all bodies and segments (body, arms and legs), body mass index and fat mass, free fat mass and body fat percentage, was measured with a dual-energy x-ray absorption metric at the beginning and after applications. Results: Between the start and after application in G1, the body mass and body mass index decreased (secondly; 82.7 ± 15.6 kg - 80.4 ± 14.2 kg, Δ=-2,3 kg; p = ,024 and 30,47 ± 5.5 kg/m2 - 29.6 ± 5.1 kg/m2; Δ = −0.84 kg/m2; p = .017). Similar results occurred in G2 (secondly; 82,0 ± 16,1 kg - 79,8 ± 15,8 kg, Δ = -2,2 kg; p = ,040 and 28,8 ± 2,4 kg/m2 - 28,0 ± 2,1 kg/m2; Δ = -0,78 kg/m2); p = .036). Free oil mass, G1 (51.8 ± 14.8 kg - 48.7 ± 13.3 kg, Δ = -3,0 kg; p = ,032), G2 (53.6 ± 14.5 kg - 50,3 ± 12.3 kg, Δ =−3.26 kg; p = ,040) and G4 (51.3 ± 12.4 kg - 47.7 ± 12.3 kg, Δ = −3,52 kg; p = ,002) groups showed a decline between start and after application. Only G4, the fat mass (22.1 ± 3.6 kg - 23.9 ± 4.4 kg, Δ = 1.8 kg; p = ,004) and the body oil percentage (29.7 ± 5.4 kg - 32.7 ± 6.3 kg, Δ = ~%3; p = .005) increased between the beginning and after application. Result: As a result, short-term training programs have not been effective in changing the body composition in a positive direction.
