ABSTRACT
It was aimed to investigate the chronic effect of FO and ST on blood parameters (glycaemia, triglycerides, and HDL, LDL VLDL cholesterol) of elderly women. METHODS: Forty-five women (64 ± 1.4 years) were assigned to one group of strength training (ST; n=15), one group of strength and 2g/day of FO supplemented by 90 (ST90; n=15) and 150 days (ST150; n=15). The ST150 started FO 60 days before commencing the strength training. Training was performed 3 times/wk, for 12 weeks. The blood parameters were assessed at before supplementation (POST60), pre-training (PRE) and post-training (POST). Positive effects were evidenced on glycaemia and HDL cholesterol when FO and exercise were combined (ST90 e ST150). The glycaemia of ST and ST150 showed no changes between PRE-POST and POST60-PRE, respectively. However, when training was combined with FO supplementation reductions in the glycaemia were found in the ST90 (21%) and ST150 (19%) from PRE to POST (p<0.05). The FO caused significant gains in HDL (ST150 POST 60-PRE). The HDL was not influenced by exercise alone (ST PRE-POS; p>0.05). However, exercise was effective when accompanied by FO supplementation (ST90, ST150, PRE-POST, p<.0.05). The triglycerides decreased when FO and exercises (p<0.05) were applied separately (ST, ST90 and ST150 POST60-POST). No additional reductions were found by combining FO and exercise. There was a reduction in the concentrations of VLDL in all groups (26% for ST, 35% in ST90, ST150 base in 35% and 36% in post ST150). The LDL was not altered. In concluision The blood parameters (triglycerides and VLDL) decreased when FO and exercises were applied separately. No additional reductionswere found by combining FO and exercise. Positive effects were evidenced on glycaemia and HDL cholesterol when FO and exercise were combined.
