Sentences with phrase «joint knee extension»

Some studies have often reported no external load type specificity of strength gains, although these are primarily limited to those reporting on programs of single - joint knee extension exercises (Manning et al. 1990; Hunter & Culpepper, 1995; Remaud et al. 2010) or programs of combined single - joint and multi-joint leg extension exercises (Walker et al. 2013).

Since the rectus femoris is a two - joint muscle, multi-joint knee extension exercises may be used with heavier loads to target this muscle, while single - joint knee extension exercises might be usefully employed with lighter loads to target the single - joint quadriceps muscles preferentially.

Not exact matches

The reviewers found few studies evaluating the effectiveness in the ACL rehabilitation process of so - called «open chain» exercises (those which tend to isolate a single muscle group and a single joint, such as leg curls and leg extensions, with or without added weight) versus «closed chain» exercises (those which work multiple joints and multiple muscle groups at once, such as, for example, a squat involves the knee, hip and ankle joints, and multiple muscles groups, e.g. quads, hamstrings, hip flexors, calves and glutes, with body weight alone or with added weight).

The hamstrings cross two joints — the knee joint and the hip joint — so they need to be trained with the help of exercises that target the knee flexion function and the hip extension function of the hamstring muscle separately.

The leg extension is a simple, limited movement which occurs only at the knee joint and can be used to strengthen the quads.

The most important function of the hams is hip extension, which as you can guess, is vital for explosiveness, sprinting, jumping and overall pelvic mobility, but they also play an important role in stabilizing the knee joint, so it's easy to understand how a pair weak, underdeveloped hams will diminish the effectiveness of your leg training, make you look like a novice and leave you at risk for imbalance and injury.

The hamstrings are responsible for knee flexion, hip extension and rotation on the knee joint when flexed.

If you opt to do the leg extension the biggest benefit is for strength around the knee joint at the last 20 - to - 30 degree of motion.

During flexion / extension of the knee joint, as in squats, jumps, and lunges, muscles in the legs, pelvic region, and core should be engaged.

Overall, the net hip joint moment observed in maximal snatch lifts seems to be much larger than the net knee joint moment, even though Olympic weightlifting is often regarded as being a sport requiring substantial knee extension strength.

Training the jerk may require improving knee extension strength, and the jerk may transfer best to movements requiring substantial net knee joint moments.

Sleds are an excellent tool to train athletic hip extension without subjecting your knees to insane joint stress.

One of the main reasons why the leg extension can be so tough on the knees is this unbalanced torque on the knee joint.

Performing a triple extension involves moving from a position in which the hips, knees and ankles are bent, to a fully extended position in which all three joints are locked.

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.

When sprinting, one the initial early acceleration phase has been completed, the joint angles of the hip and knee during the ground contact phase range from 30 degrees of flexion through to full extension.

Avoiding full extension of your elbows, knees, and hips has the added benefit of reducing wear and tear on your joints.

Although yin work with the knee would seek full flexion and extension (bending and straightening), it would never aggressively stretch this extremely vulnerable joint.

Riemann et al. (2012) also noted that the hip extension moment impulse increased more with increasing load than either ankle or knee joint moment impulses.

Riemann et al. (2012) measured hip extension moment impulses during lunges with different loads and found that increasing load led to increased ankle and hip joint moment impulses but not increased knee joint moment impulse.

In one study, Remaud et al. (2010) assessed joint angle - specific changes in maximum voluntary isometric contraction (MVIC) torque and in neural drive after isotonic and isokinetic types of external load, using knee extension training.

Using eccentric - only knee extension training, Guilhem et al. (2013) assessed the effect of constant load and isokinetic external load types on joint - angle specific changes in torque and EMG amplitude.

Three of them are two - joint muscles (performing both knee flexion and hip extension) while the fourth performs only knee flexion.

Compare the bench press (shoulders and elbow joints) versus the dumbbell fly (elbows only), or the squat (ankles, knees, hips) versus the leg extension (knees only).

The primary function of the muscles surrounding the knee is to provide flexion and extension of the joint; it also has the capability for slight rotation, but this is very minimal and normally not discussed in most text.

1In a study on 46 subjects, individuals using a core ingredient in Six Star ® Joint & Muscle Recovery in combination with a training protocol significantly increased their range of motion on knee extensions compared to subjects using a placebo (81 vs. 74 degrees).

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.

Later similar research confirmed this, as the increases in hip extension net joint moments with increasing running speed were found to be greater than the increases in knee extension net joint moments, or work done (Simpson & Bates, 1990; Belli et al. 2001; Kuitunen et al. 2002; Schache et al. 2011; 2014; 2015).

Test of transfer (long - term): Strength training that targets the hip extensors close to full extension (such as with the hip thrust), and the knee extensors at around 40 degrees from full extension (such as with the quarter squat), may well transfer better to sprinting than strength training that targets the hip and knee extensors at other joint angles.

This study tested muscle activation during maximum voluntary contractions of hip extension, in different hip flexion joint angles while the knee was flexed, and found that gluteus maximus EMG amplitude was reduced by a third when the hip was flexed, compared to when it was fully extended.
