Abstract The human ankle joint and plantar flexor muscle–tendon unit play an important role in endurance running. It has been assumed that muscle tendon interactions their biomechanical behaviours depend on morphological architectural characteristics. We aimed to study how characteristics influence marathon running performance determine whether there is any difference the of soleus gastrocnemii. right lower leg ten male distance runners was scanned with magnetic resonance imagining....
Currently, limited information is available on the influence of quadriceps femoris muscle–tendon unit morphological parameters mechanical efficiency; therefore, aim this study was to investigate interaction between these variables. The characteristics nine healthy females (22 ± 0.9 years) were assessed using magnetic resonance imaging. efficiency a dynamometer. During contractions, electromyographic activity vastus lateralis and rectus recorded. highest achieved with moderate pretension 20 J...
Abstract The mechanical efficiency of the quadriceps femoris muscle-tendon unit likely depends on its structural and properties. Therefore, purpose this study was to assess in vivo under various stretch-shortening cycle conditions investigate how morphological properties influence efficiency. We used MRI measure muscle tendon young females ( n = 9), we determined during contractions using computer-controlled dynamometer. Testing protocol included with moderate maximal pretension level...
Arm swing improves vertical jump height but the underlying mechanism is not well understood. We assume that negative acceleration of arm can increase load and tension lower limb's extensor muscles enhancing force output resulting in higher jump. The purpose this study was to examine how affects EMG activity limb during jumping relation kinematics. Sixteen physically active male college students were asked perform squat (SJ) countermovement jumps (CMJ) with arms akimbo swing. Jumps carried...
Based on the current literature, link between Achilles tendon moment arm length and running economy is not well understood. Therefore, aim of this study was to further investigate connection influence function plantarflexor muscle-tendon unit during running.Ten male competitive marathon runners volunteered for study. The participants ran a treadmill at two speeds: 3 3.5 m s-1. During oxygen consumption, lower leg kinematics, electrical activity plantar flexor muscles, fascicle behavior...
Footstrike pattern has received increased attention within the running community because there is a common belief that forefoot strike (FFS) more advantageous (i.e., improve performance and reduce injuries) than rearfoot (RFS) in distance running. Literature reports suggest greater knee joint flexion magnitude initial angle during stance FFS compared with RFS We examined EMG activation of triceps surae muscles an acute transition from to strike. tested hypothesis due larger gastrocnemius...
It has been suggested that certain lower leg variables affects running and jumping performance.However, it is unclear how these interact with each other, they jointly affect hopping performance.We assume AT-MA influences the physical performance differently depending upon biomechanical of plantar flexor muscles.We hypothesize no single variable can explain height, rather a combination variation in height.Healthy young adults (n = 28, age 21.8 ±4.0 yrs) performed serial hops on force plate...
