ABSTRACT
Objective To explore the effect of bio-resonance on walking efficiency in healthy youths. Methods Ten young male participants were involved in this study (age 16 ± 2 years, height 1.73 ±0. 1 m and weight 56. 1 ± 7 kg). The time-space data were collected using a motion analysis system, and oxygen cost was meas-ured with a Cosmed K4b2 portable gas analysis system. Walking at a self-selected, comfortable walking frequency was recorded through three dimensional gait analysis. Each participant walked at 100% , 80% and 120% of their comfortable walking frequency. Results The average 100% , 80% and 120% comfortable walking frequencies were 107.60 ± 1.78, 85.80 ± 7.45 and 128.60 ±10.46 steps/min, respectively. Oxygen consumption at the three frequencies was significantly different (P≤0.01), and the oxygen costs were 0. 140 ± 0.011, 0. 193 ± 0. 049 and 0. 192 ± 0. 035 ml/m/kg, respectively. Above or below the self-selected pace, oxygen cost increased significantly (P ≤0.05). Conclusion There is an inherited bio-resonance in human walking, and walking with this natural rhythm is reflected in the lowest oxygen cost. Any change from the natural walking rhythm may result in increased en-ergy expenditure and decreased efficiency.
