The intervention measures encompass the implementation of simulated vigorous intermittent lifestyle physical activity for all participants. The specific exercise regimen involves performing rope jumping activities three times a day, with each session aimed at surpassing the exercise threshold (not conducted in a continuous manner), where the heart rate should exceed 160 beats per minute. This routine will be undertaken five times a week, continuously for a span of 8 weeks.

Isokinetic strength testing with the Isomed 2000

a standard surface electromyography system (MyoMove-EOW, NCC, China) was utilized. Surface electrodes were placed using the belly tendon method at 6 specified locations on both sides of the lower legs (anterior tibialis on both sides, gastrocnemius on both sides, and soleus on both sides). The electrode placement positions and operational procedures strictly adhered to the SENIAM guidelines (http://www.seniam.org). During the testing process, root mean square (RMS) and averaged electromyography (AEMG) values were collected to reflect the muscle force and motor unit recruitment of the selected muscle groups.

encompassing high-density lipoprotein cholesterol (HDL-C) and triglycerides, were assessed using the CardioChek device (Polymer Technology Systems, Inc., 7736 Zionsville Road, USA)
