Key result
Nordic Walking and conventional walking both increased aerobic capacity and decreased total cholesterol over 12 weeks in women over 55, with no significant difference between the groups.
Why the study?
The study was conducted to investigate the effects of Nordic Walking compared to conventional walking on aerobic capacity, lipid profile, left ventricular ejection fraction, body mass, and body mass index in women over 55 years old.
Does Nordic Walking improve aerobic capacity and lipid profile compared to conventional walking in women over 55 years of age?

Does Nordic Walking improve aerobic capacity and lipid profile compared to conventional walking in women over 55 years of age?
Both Nordic walking and conventional walking similarly improve aerobic capacity and reduce total cholesterol in women over 55 years of age.
Either walking form improves fitness and lipids in women >55; confirms conventional walking suffices without poles.
BACKGROUND: The purpose of this study was to investigate the effects of Nordic Walking compared to conventional walking on aerobic capacity, the lipid profile, left ventricular ejection fraction, body mass, and body mass index in women over 55 years old. METHODS: The study was comprised of 74 women over 55 years of age. Participants were randomized to the Nordic Walking (n = 38) or conventional walking (n = 36) training groups. The echocardiogram, treadmill exercise stress test, lipid profile, and body mass were assessed at baseline (pretest) and after 12 weeks (posttest). RESULTS: The authors found a significant main effect over time in duration (effect size [ES] = 0.59, P < .0001), distance covered (ES = 0.56, P < .0001), peak oxygen consumption (ES = 0.43, P < .0001), metabolic equivalent (ES = 0.29, P < .0001), peak heart rate (ES = 0.2, P < .0001), peak diastolic blood pressure (ES = 0.11, P = .0045), total cholesterol (ES = 0.26, P < .0001), and low-density lipoprotein cholesterol (ES = 0.16, P = .0005). The authors did not observe a time versus group interaction or the effect between groups. Post hoc tests revealed significant pretraining to posttraining differences in low-density lipoprotein cholesterol after the Nordic Walking training program and in peak diastolic blood pressure after the conventional walking training program. The heart rate, systolic blood pressure, and diastolic blood pressure at rest, peak diastolic blood pressure, somatic parameters (body mass and body mass index), and left ventricular ejection fraction did not change in either group. CONCLUSIONS: Both training programs resulted in increases in aerobic capacity and decreases in total cholesterol.

Witkowska et al. (2021) reported an RCT. Nordic Walking vs. conventional walking was evaluated on aerobic capacity, the lipid profile, left ventricular ejection fraction, body mass, and body mass index. Nordic Walking and conventional walking both increased aerobic capacity and decreased total cholesterol over 12 weeks in women over 55, with no significant difference between the groups.
