3. Perform ten resistance training exercises and describe which phase of the exercise is the eccentric, concentric and isometric phase of the movement. At which phase is the muscle the strongest? Why?
When performing the bench press, lowering the bar to your chest (down phase) this movement is considered an eccentric contraction. When lifting the bar off your chest (up phase) this movement is considered a concentric contraction. If we modify the exercise and we bring the weight down to the chest and hold this position, this fixed position of the bar is considered an isometric contraction. During the up phase, the pectoralis major is at its strongest because the muscle is contracted at its full potential, holding and maintaining the weight

As the body lowers in this exercise, the chest, shoulders, triceps, and abdominals are all contracted, which is a concentric contraction. As the body rises back up to the starting position, this movement is an eccentric contraction. The muscles are at its strongest in this exercise when the body is in the down phase and maintaining a muscle contraction on the way back up to the starting position.
Upright rows, when the barbell is raised, this movement is a concentric contraction. During this contraction, the trapezius are at its strongest in this point in the movement. As the weight is lowered back to its starting position, this movement downward is an eccentric contraction.
Barbell rows, when the body is about to perform the exercise (preparatory phase) and is griping the bar, this is an isometric contraction. When the bar is raised and touching the upper abdominals, this is a concentric contraction. The latissimus dorsi, trapezius, posterior deltoids and biceps, are all activated during this exercise and are the strongest when the bar is touching the upper portion of the abdominals. When the bar is lowered and brought back to the starting position, this is an eccentric
This exercise is done with a barbell and a incline bench (“Exercises”). The way to do this exercise is to lie down faced up on an incline bench. The exerciser grips the bar with a medium-width grip and lifts the bar off of the rack (“Exercises”). the exerciser then holds the bar straight over his or her head, and keeps the arms locked. This is the starting position of the exercise. Next the exerciser inhales slowly while moving the bar slowly down toward the upper chest (“Exercises”). After a slight pause, the exerciser pushes the bar back to the starting position while exhaling and the arms should be locked. Before the exerciser brings the bar back down again the exerciser squeeze the chest for a second. The exerciser repeats the process for the desired number of repetitions. When the exerciser is finished with the exercise the bar should be placed back on the rack (“Exercises”).
Comparing deltoid and lumbar muscle activation is an unfair advantage in favor of the Shake Weight, as the shoulder position is different. The Shake Weight model has the arms elevated while the dumbbell model has her elbows at her sides. By default, the anterior deltoids and the muscles of the lower back will have a greater contraction.
The major muscle groups consist of the upper body, Rotator cuff muscle, Upper arm, Quadriceps, Hamstring group, Lower leg and Midsection. The Upper Body consists of the Trapezious muscle which Orgin is located near the base of skull, occipital protuberance and posterior ligaments of neck. The middle spinous process of 7c and T1 - T3. The lower spinous process of T4-T12. The insertion of the upper Trapezius is located in the posterial aspect of the lateral clavicle. The middle Trapezius is located in the medial border
One example of an exercise using a combination of several of these movements together is jumping squats with free weights. This exercise targets the lower body, core and also the upper body. The quadriceps, the hamstrings, the gluteal, the lower back and the abdominals. The back muscle act as stabilizers to keep the body in a correct balance position. In the explosion phase, hip extends in a slight adduction knee extension and ankle plantar flexion. During the landing phase, back into the squat position, all the muscle is in an eccentric position, the hip flexion with slight abduction, knee flexion, and ankle dorsiflexion. Jumping squats with weights are just one of the extended workouts that utilize these principles. It is very important to understand the fundamental movements of major body segments in order to design and execute appropriate workout for my clients and their personal
The left shoulder abduct concentrically by the deltoids to provide balance for the body. The cervical spine flex laterally sternocleidomastoid. The lumbar spine of the body flex laterally by concentric contractions of the rectus abdominis. The shoulder girdle adducted by isometric contractions of the middle trapezius, upper trapezius, and rhomboids. The elbow extends and flex by isometric contractions of the triceps brachii and biceps brachii on both sides. The wrist extends concentrically by the extensor carpi radialis longus, extensor carpi radialis brevis, extensor pollicis longus, extensor digiti minimi, extensor indicis, extensor digitorum, and extensor carpi ulnaris. The metacarpophalangeal and interphalangeal are extended by concentrically by extensor pollicis brevis, extensor pollicis longus, extensor digiti minimi, extensor indicis, and extensor digitorum on left and right side of the
Abs braced. Shoulders back and down. Chest lifted. Hips down. Kick feet as far back as possible. Stand straight up to complete.
Tennis is one of the most strenuous sports since every group muscle is activated while playing this type of game. Due to this reason, it is important for strength and conditioning coaches to create a suitable resistance exercise program for their tennis players. In order to create a right resistance training program, every coach needs to perform a needs analysis for each player since everyone has different demands and body physique. While trying to figure it out what is the best for each individual questions such as should be asked: “Which muscles are working the most while playing tennis?” or “What are the weaknesses of the athlete?”. After that strength and conditioning coach should consider factors such as: selection of exercises,
Use your forearm to push your hip up off of the floor. Keep your head and neck aligned with your spine and hold this position for two seconds. Do several repetitions and repeat on the other side of your body. Repeat on both sides ten times and work your way up to at least twenty repetitions per work out session. In addition to your abdominal muscles, this exercise also strengthens your obliques and shoulders.
This form will include strong bounce with other unwanted momentum. In this kind of form your body will move backword and you will also use your knees to support the weight going up for. This kind of technique allows you to lift more weight.
This plank or abdominal bridge is an isometric core strength exercise that involves maintaining a static position for a period of time. The most common plank is the front plank which is held in a push-up position with the body's weight borne on forearms, elbows, and toes. Lie on floor, get into pushup position. Now bend your elbows 90 degrees and rest your weight on your forearms.
The prime movers in the left shoulder that move it back to its neutral position are the anterior deltoid and the bicep brachii. Concentric contractions followed by eccentric contractions of both of these muscles move the shoulder from extension and abduction to it neutral state by flexing and adducting the shoulder. The prime movers in the right shoulder are again the anterior and middle deltoid along with the supraspinatus that contract isometrically to keep the shoulder in horizontal abduction. When the right shoulder is let down after follow through, the prime movers are the triceps and the posterior deltoids which eccentrically contract to extend the shoulder to its neutral position. Therefore the muscles of the shoulder are exceedingly imperative to the action of shoot a
The squat also activates the core muscles such as the Rectus abdominis and obliques as they are required in order to stabilize the body during the squat movement.
Your gaze is forward over the left hand. Both thighs are rotating outward. Engage your triceps to support your arms, your quadriceps to support your legs, and your belly to support your torso.
The sit up is a callisthenic abdominal exercise that targets the rectus abdominal muscles. The sit up or knee bend abdominal exercise is done in two (2) phases the upward phase and the downward phase .In the upward phase the muscle action taking place is concentric, the muscles that are working concentrically are also working eccentrically in the downward phase. The bend knee sit up takes place along the sagittal plane and mediolateral axis where there are flexion and extension of the joints. The purpose of this exercise is to strengthen the core muscles better known as the Rectus Abdominis muscles. The Rectus Abdominis muscles is the prime mover or the agonist muscles while , the muscles that help or assist the Rectus Abdominis is the Iliopsas,Tensor
The set of chest and back exercises target strength and definition using two classic exercises for the upper-body, pull-ups and push-ups. These workouts build powerful muscles and sculpt shape. Together, the burn calories and assist body weight control.
