“…Although contact period of skip and run is similar, descent velocity during bounce rope-skip was 63% higher than run and 89% higher than walk. Higher descent velocity during bounce rope-skip is speculated to provide greater kinetic energy for take-off of subsequent rope-skip cycle as reported earlier ( Chow et al., 2014 ). It is argued that greater kinetic energy is directly associated with power generation during bounce rope-skip; which is illustrated by 47% higher power generation at ankle and knee compared to run.…”

“…Although several studies report physiological benefits of bounce rope-skip, there is paucity of literature informing biomechanics of bounce rope-skipping. Kinematics of rope jumping during bounce skip, jump skip, alternate leg skip and bell skip are reported ( Chow et al., 2014 ). It is known that vertical ground reaction force (GRF) is low during alternate leg skip ( Chow et al., 2014 ).…”

It is known that vertical ground reaction force (GRF) is low during alternate leg skip ( Chow et al., 2014 ). However, GRF is highest during bounce rope skip and demonstrates a linear relationship with take-off velocity and jump height ( Chow et al., 2014 ).…”

As a simple and beneficial way of exercise, rope skipping is favored by the majority of teenagers, but incorrect rope skipping may lead to the risk of injury. In this study, 16 male adolescent subjects were tested for bounced jump skipping and alternating jump rope skipping. The kinematic data of the hip, knee, ankle and metatarsophalangeal joint of lower extremities and the kinetics data of lower extremity touching the ground during rope skipping were collected, respectively. Moreover, the electromyography (EMG) data of multiple muscles of the lower extremity were collected by Delsys wireless surface EMG tester. Results revealed that bounced jump (BJ) depicted a significantly smaller vertical ground reaction force (VGRF) than alternate jump (AJ) during the 11–82% of the ground-contact stage (p < 0.001), and the peak ground reaction force and average loading rate were significantly smaller than AJ. From the kinematic perspective, in the sagittal plane, when using BJ, the flexion angle of the hip joint was comparably larger at 12–76% of the ground-contact stage (p < 0.01) and the flexion angle of the knee joint was significantly larger at 13–72% of the ground-contact stage (p < 0.001). When using two rope skipping methods, the minimum dorsal extension angle of the metatarsophalangeal joint was more than 25°, and the maximum was even higher than 50°. In the frontal plane, when using AJ, the valgus angle of the knee joint was significantly larger during the whole ground-contact stage (p < 0.001), and the adduction angle of the metatarsophalangeal joint (MPJ) was significantly larger at 0–97% of the ground-contact stage (p = 0.001). EMG data showed that the standardized value of root mean square amplitude of the tibialis anterior and gastrocnemius lateral head of BJ was significantly higher than AJ. At the same time, that of semitendinosus and iliopsoas muscle was significantly lower. According to the above results, compared with AJ, teenagers receive less GRF and have a better landing buffer strategy to reduce load, and have less risk of injury during BJ. In addition, in BJ rope skipping, the lower limbs are more inclined to the calf muscle group force, while AJ is more inclined to the thigh muscle group force. We also found that in using two ways of rope skipping, the extreme metatarsophalangeal joint back extension angle could be a potential risk of injury for rope skipping.
