Estimation of energy expenditure of Nordic walking: a crossover trial

Abstract Background Nordic walking (NW) requires more energy compared with conventional (W). However, the metabolic equation for NW has not been reported. Therefore, this study aimed to characterize responses in oxygen uptake, minute ventilation, heart rate, systolic blood pressure, and surface electromyography of upper lower limb muscles during W develop a expenditure ( E , mL·kg − 1 ·min ) NW. Methods This was performed randomized, controlled, crossover design test W. Fifteen healthy young men were enrolled (aged 23.7 ± 3.0 years). All participants two randomly ordered tests (NW W) on treadmill at predetermined stepwise incremental speed (3–5 km·h grade (0–7%). The signals three their right body recorded between using paired-t test. Multiple linear regression analysis used draw estimation Results Oxygen uptake (+ 15.8%), ventilation 17.0%), rate 8.4%), pressure 7.7%) higher than P < .05). resulted increased muscle activity all In limb, activities only level Energy estimated as follows: = 6.1 + 0.09 × 1.19 4.4 1.20 grade. Conclusion showed work intensity W, an consumption difference 1.7 . coefficients different methods. involved
