..However, the results suggested that walking with a backpack of greater than 10% body mass induced significant changes in trunk posture and respiratory parameters in 10-year-old children...

..Therefore, human could walk without slip on slippery surfaces with greater toe grip and gentler heel strike as adaptation strategies...

..DISCUSSION AND CONCLUSION: Support patterns changed slowly, and, combined with various step directions, they were found to be better than those of walking in simulating the gait challenges that may be encountered in daily activities...

..CONCLUSIONS: The plantar pressure characteristics of Tai Chi movements found in this study may be one of the important factors that Tai Chi exercise improves balance control and muscle strength...

..Higher activity of rectus femoris and gastrocnemius were found in the late stance and the swing phase respectively...

..Tai Chi was found to be more effective than walking in simulating the gait challenges that are encountered in daily activities...

..2% vs. 73.1%, p = 0.007). No significant difference was observed in other multiple comparisons. Different surfaces affected the plantar loads while running. The differences may help us to understand potential injury mechanisms...

..In conclusion, the cloth sport shoe showed inferior cushioning capability but the same lateral stability as the other sports shoes for children...

..This paper reviews studies that have explored the biomechanical aspects of Tai Chi, such as balance, kinematics, kinetics, strength, and neuromuscular activities...

..25 times that in descent with no load, 1.89 times that in ascent with the same load, and 2.19 times that in ascent with no load. The force-to-time ratio in descent was about three times that in ascent...

..It is suggested that backpack loads for children should be restricted to no more than 15% body weight for walks of up to 20 min duration to avoid muscle fatigue...

..The purpose of this study was to investigate the lower-extremity kinematics when walking on potentially slippery surfaces in simulated construction worksite environments...

..The carrying weight of a school bag for children could be recommended as 10% of body weight because it was not significantly different from 0% load in the metabolic cost...

..There has apparently been no research into the effects of TCC on total body rotation flexibility and heart rate responses at rest and after a three minute step test...

..However, the magnitude of the exercise effects on muscles might depend on the characteristics of different types of exercise...

..We investigate kinematic adaptation and muscle activities in the trunk and lower extremities of healthy subjects during treadmill walking in negative-heeled sports shoes versus normal sports shoes...

..026). There were no significant differences between the S/R group and the control group (p = 0.312), the TC group and S/R group (p = 0.533). For knee extension, no significant difference was noted among the three groups (p = 0.597)...
