considerations. Jumping rope (JR) is a consecutive jump exercise with turning the rope, involving mainly foot muscles and joints, due to the quick rebounds. 11 Therefore, JR might be considered a type of PT for improving power and stiffness, some of the key factors for endurance running performance. 4

containing equal parts of gelatin and HC. One hour later, the subjects were asked to jump rope to stimulate bone collagen synthesis, and after a further 4 hr, blood was drawn to determine the circulating levels of the N-terminal peptide of procollagen (PINP). PINP in the blood primarily represents bone

Bone remodeling as a response to exercise in human subjects is described in the literature, although most studies treat exercise as a qualitative factor contributing to bone remodeling. Quantitative description requires assessment of the mechanical loads on the bones. This work describes a generalized lower extremity model that uses existing musculoskeletal modeling techniques to quantify mechanical variables in the femoral neck during exercise. An endurance exercise program consisting of walking, jogging jumping rope, and weight-training was analyzed. Peak femoral neck cortex stresses and strains were high during jogging and squatting, compared to walking, whereas jumping rope and other weight-training exercises produced peak stresses comparable to or lower than walking. Peak stress and strain rates were significantly higher for walking, jumping rope, and jogging than for weight-training. The model should prove useful for any study investigating a quantitative relationship between exercise and bone remodeling.

This study determined the metabolic equivalents (METs) of several activities typically performed by Chinese youth.
Thirty youth (12 years) performed 7 activities that reflected their daily activities while Energy Expenditure (EE) was measured in a metabolic chamber.
METs were calculated as activity EE divided by participant’s measured resting metabolic rate. A MET value ranging from 0.8 to 1.2 was obtained for sleeping, watching TV, playing computer games, reading and doing homework. Performing radio gymnastics had a MET value of 2.9. Jumping rope at low effort required 3.1 METs. Except for watching TV, METs for other activities in this study were lower than Youth Compendium values.
The results provide empirical evidence for more accurately assessing EE of activities commonly performed by Chinese youth. This is the first study to determine METs for radio gymnastics and jump rope in Chinese youth.
