BACKGROUND: Physical exercise is the main strategy for improving physical fitness in elderly population. However, it is not clear which training method lead to greater adaptations on maximal dynamic strength, muscle power, muscle endurance and isometric strength in this population. Thus, our aim was to compare the effects of functional and traditional training on these variables in the elderly.
METHODS: This study lasted twelve weeks, where 44 elderly women were randomly divided into three groups: functional training (FT; N.=18), traditional training (TT; N.=15), and control group (CG; N.=11). Maximal dynamic strength and muscle power tests were performed in pushing (Chest Press), pulling (Seated Row), and squatting (Leg Press 45°) actions. In addition, isometric strength with hand grip test (HG) and isometric dead lift test (ID) and muscle endurance with 30-s chair stand (CS) and 30-s arm curl (AC) tests were used.
RESULTS: Both experimental groups improved significantly in strength (FT: Chest Press 24.9%, Leg Press 45° 38.4%, Seated Row 21.6%; TT: Chest Press 27.6%, Leg Press 45° 40.9%, Seated Row 24.5%), power (FT: Chest Press 13.6%, Leg Press 45° 11.6%, Seated Row 13.6%; TT: Chest Press 18.2%, Leg Press 45° 9.8%, Seated Row 19.2%) isometric strength (FT: HG=14.7%, ID=13.6%; TT: HG=19.1%), and endurance (TF: CS=19.6%, AC=23.8%; TT: AC=15.5%) with P≤0.05, except TT in ID (4.4%) and SL (4.6%). There was no difference between experimental groups; however, both experimental groups were statistically superior to CG.
CONCLUSIONS: Both training protocols were equally effective in improving different strength manifestations in the elderly.
