Purpose of the Study:
The aim of the study was to analyze the effects produced by the use of experimental program of Nordic walking on functional abilities in elderly women.
The study involved included 60 women from Novi Sad community, mean age 58.5±6.90 years, mean body mass 70.9±15.32 kg and mean body height 164.8±7.24 cm. The study population was divided into two groups of 30 subjects: experimental (NW) group and control (C) group. All subjects were enrolled in the study on a voluntary basis. The experimental group included elderly women attending fitness program specially designed for this age group at a local recreation center, while the control group included 30 randomly selected elderly women.
Procedure or Methods:
The experimental program was performed three times a week for three months. During the study, the subjects were not engaged in any other physical activity. Control group women performed no physical activity during these three months. The experimental group performed supervised Nordic walking program.
During the program, correct performance, intensity and volume of NW were surveyed by fourth-year students of the Faculty of Sports and Physical Education.
The NW program lasted three months, i.e. three training sessions per week for 12 weeks, making 36 training sessions during three-month treatment. The intensity was defined for each subject individually based on heart rate and was modified after four weeks.
The program was divided into three parts differentiated by the volume and intensity:
Functional abilities were assessed by the following measurements:
Resting heart rate (HRR; bpm);
systolic blood pressure (BPS; mm Hg);
diastolic blood pressure (BPD; mm Hg);
fitness index (FITIND) in the UKK2-km walking test;
VO2max (mL/kg/min) in the UKK2-km walking test.
On final measurement, pulse at rest (NW=73.42<C=79.68), systolic blood pressure (NW=118.42<C=123.65) and diastolic blood pressure (NW=79.04
<C=8.54), showed lower results in the NW group as compared with control group. The supervised NW program led to a decrease in the values of pulse at rest, systolic
and diastolic blood pressure in experimental group. Before the program the values of FITIND was less than 70 (C=62.66) and in the elderly are considered
to be “Clearly below average” UKK 2 km Fitness Index category. On final measurement, the variables of FITIND in the NW group were 81.79. The value 70-89 means “Slightly below average” UKK 2 km Fitness Index category. All subjects in the NW and the C groups had a very low VO2max level. VO2max was 16.81 mL/kg/min or 4.8 MET at the beginning and 21.83 mL/kg/min or 6.2 MET value showed in the experimental NW group as compared with the control group, reflecting improvement of functional abilities after the NW program.
In this study, the three-month supervised Nordic walking program reduced the values of pulse at rest and blood pressure, while improving the values of UKK 2 km Fitness Index and VO2max in elderly women.
Nordic Walking training causes a decrease in blood cholesterol in elderly women supplemented with vitamin D
Objective: Different studies have demonstrated that regular exercise can induce changes in the lipid profile, but results remain inconclusive. Available data suggest that correction of vitamin D deficiency can improve the lipid profile. In this study, we have hypothesized that Nordic walking training will improve lipid profile in elderly women supplemented with vitamin D. MethodsThe total of 109 elderly women (68 ± 5.12 years old) took part in the study. First group (Experimental:EG, 35 women) underwent 12 weeks of Nordic Walking training combined with vitamin D supplementation (4000 IU per day), second group (Supplementation: SG, 48 women) was only supplemented with vitamin D (4000 IU per day), and third group (Control: CG, 31 women) was not subject to any interventions. . Blood analysis of total cholesterol (TC), triglycerides (TG), HDL-C, LDL-C, 25-OH-D3 was performed at baseline and after the 12 weeks of Nordic Walking training. Additionally, a battery of field tests specifically developed for older adult
