Assessment of lateral symmetries (LS) lower limbs has been widely investigated. However, there are no studies about LS during exposure to high eccentric and concentric loads flywheel (FW) squats. A total 422 young, physically active participants performed squats on an FW device with different equidistant (0.05, 0.125 0.2 kg∙m2). The mean peak force the left right leg were assessed for contactio...

The purpose of this research was to determine the functions of the gluteus maximus, biceps femoris, semitendinosus, rectus femoris, vastus lateralis, soleus, gastrocnemius, and tibialis anterior muscles about their associated joints during full (deep-knee) squats. Muscle function was determined from joint kinematics, inverse dynamics, electromyography, and muscle length changes. The subjects we...

As the stimulus for bone adaptation, bone strain is an indicator of the effectiveness of bone strengthening exercise. A flexible multibody analytical approach was used to calculate leg bone strain based on motion capture data taken as a human subject performed a number of exercises. Four typical leg strengthening exercises were studied: leg press, knee flexion, knee extension, and squats with f...

Sparse signals are encountered in a broad range of applications. In order to process these using digital hardware, they must first be sampled and quantized an analog-to-digital convertor (ADC), which typically operates serial scalar manner. this work, we propose quantization sparse time sequences (SQuaTS) method inspired by group testing theory. This is designed reliably accurately quantize acq...

Rail squats are a type of isolated railhead fatigue defect that costs Network millions pounds every year. Despite significant research into the topic there is still lack detailed understanding on how initiated and propagated or best methods to maintain track in order manage squat defects. This paper presents correlation analysis examining which characteristics might be associated with initiatio...

ABSTRACT Introduction Athletics has high requirements for resistance and strength. Therefore, more researchers are focusing on improving these athletes’ endurance muscular strength, prioritizing their sports performance. Objective Explore methods of adding to conventional training increase performance muscle strength in track field. Methods Volunteers the experiment control groups were randomly...
