Sentences with phrase «as knee flexion»

However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).
This is a very important muscle group for athletes though, because it performs multiple functions crucial for explosive strength, such as knee flexion and hip extension.

Not exact matches

Push your hips backs as your knees bend, lowering your body closer to the floor until you reach 90 - degree knee flexion.
As a result lifters tend to take a more vertical position, with increased flexion of the knee.
They're called hip flexors because they create flexion in the hip, which is the technical term for a bending movement around a joint in a limb (such as the knee or elbow) that decreases the angle between the bones of the limb at the joint.
Flexion: Bend your body forward at the joints, such as at the waist for sit - ups or at the knees for high - step exercises.
During flexion / extension of the knee joint, as in squats, jumps, and lunges, muscles in the legs, pelvic region, and core should be engaged.
The gastrocnemius also acts as a weak knee flexor, and is capable of producing its greatest plantar - flexion moment with the knee extended.
In fact, front and back squats are more similar than they are different — both require massive amounts of strength / stability in the hips and core, as well as requisite «access» to hip flexion, knee extension, and ankle dorsiflexion — so I really see little need to get all territorial about which one is better.
The origins of the gastrocnemius (medial and lateral heads) are such that the two heads cross both the knee and ankle joint and consequently function as both an ankle extensor (plantar - flexion) and as an accessory knee flexor and stabiliser.
Peak knee flexion angles are less acute when using cues to prevent forward knee movement over the toes or as a result of fatigue.
Correspondingly, the five phases that can be described between these positions are as follows: (1) the first pull happens between the ground and when the bar reaches knee level and is initiated by knee and hip extension; (2) the transition happens when the barbell is between knee level and the power position and involves a shift in the position of the body relative to the barbell, which involves a brief period of knee flexion and is therefore referred to as the double knee bend (Enoka, 1979; 1988); (3) the second pull is the most powerful phase of the lift and occurs while the barbell is between the power position and the lifter is in triple extension; (4) turnover occurs as the lifter quickly drops down under the bar from the triple extension position to the catch position, in a deep front squat; (5) recovery into the standing position occurs as the lifter stands from the catch position to upright.
They're called hip flexors because they create flexion in the hip, which is the technical term for a bending movement around a joint in a limb that decreases the angle between the bones of the limb at the joint (such as the knee or elbow).
Their primary hamstrings role is knee flexion, which is characterized by curling your leg backward as if you're trying to kick your ass with your heel.
As explained in the quadriceps section above, hip flexion is demonstrated by lifting your knee / leg towards your chest (or lowering chest towards legs).
Hamstring strains are usually caused by a forceful hip flexion while the hamstring is working to slow the extension of the knee as in kicking or running.
Hip extension, knee extension, and ankle plantar - flexion net joint moments increased markedly as side - step distance increased, while hip abduction net joint moments did not alter much at all.
Unlike sprinting, this eccentric strength is likely necessary for the hip extensors and knee extensors, as the COD maneuver usually involves combined hip flexion and knee flexion.
This is the same finding as for resistance training exercises, where isolated knee flexion exercises (such as leg curls) produced the best results with the greatest regularity.
It was originally suggested that hamstring strain injury occurred most commonly during the early stance phase, as this is where both knee flexion and hip extension moments are highest (Mann & Sprague, 1980).
In general, it seems that exercises from the knee flexion category (i.e. leg curls) almost always feature as one of the best exercises, while exercises from the hip extension and knee extension category (i.e. squats) never feature as one of the best exercises.
In contrast, in the descending phase, both upper and lower erector spinae muscle activity grew higher as the knee angle increased from the top portion of the lift (0 — 30 degrees knee flexion) to the bottom portion (61 — 90 degrees knee flexion).
As a group, the hamstrings can therefore be trained by exercises that involve either hip extension or knee flexion.
For those of you who aren't familiar with that terminology, think of knee flexion as a leg curl — where you are taking your foot and moving it towards your glutes in one fluid motion.
However, a safe, simple and effective way to for a beginner to started an abdominal program is to emphasize basic abdominal flexion exercises such as crunches, stability ball crunches, cable crunches, hip lifts, full range knee ups and reverse crunches.
The squat, for instance, is the most notable and probably the best of all glute exercises; it involves flexion and extension at the ankle, knee, and hip joints as well as recruitment of the gluteal (gluteus maximus), quadriceps, and hamstring muscle groups.
Gluteus maximus EMG amplitude can be enhanced during back extensions by performing the exercise in a position of knee flexion and / or in hip external rotation, and by adding external loads (such as by wearing a weighted vest or holding a dumbbell or weight plate).
