MSK System Essentials

This system is used for ATP production during high intensity, short duration exercise, such as sprinting 100 meters. Provides energy for muscle contraction for up to 15 seconds.

This system supplies ATP during high intensity, short duration exercise, such as sprinting 400-800 meters. Provides energy for muscle contraction for 30-40 seconds.

This system supplies ATP during low intenisty, long duration activities, such as running a marathon. The amount of ATP production is far greater, but requires a complicated serise of chemical reactions.

Common joint receptors include:

Type of muscle fiber that is described as aerobic, red, tonic, slow twitch, and slow-oxidative.

Type of muscle fiber that is described as anaerobic, white, phasic, fast twitch, and fat-glycolytic

Distributed throughout the belly of the muscle and function to send information to the nervous system about muscle length and/or the rate of change in its length

The shoulder complex is formed by the following joints:

The elbow joint is formed by the following joints:

The wrist complex is formed by the following joints:

The ankle and foot are formed by the following joints:

A health range of boy fat for male and women is:

Occurs when a two-joint muscle contracts across both joints simultaneously

Occurs when a two joint muscle is lengthened over both joints simultaneously

This principle states that in order for a muscle to adapt and become stronger, the load that is placed on it must be greater than what it's normally accustomed to. In resistance training, the volume (sets, reps) or intensity can be altered to provide greater challenge to the muscle.

This principle states that the body will adapt according to the specific type of training that is utilized. To bring about an improvement in a patient's function, the type of training should specifically mirror the desired goal.

This principle states that there can be a carryover effect from one exercise or task to another. For example, a patient who performs exercises to improve muscular strength may also see improvements in muscular endurance (however, these carryover effects are far less beneficial than the results from more specific training)

This principle states that the adaptations seen with resistance training are reversible if the body is not regularly challenged with the same level of resistance or great.er These reversible effects can begin within 1-2 weeks of stopping an exercise program.

A principle that states that the ability of a muscle to produce force depends on the length of the muscle. A muscle can usually produce a maximal force near its normal resting length. If the muscle is lengthened or shortened, it will likely produce less force.

A principle that states that the speed of a muscle contraction affects the force that the muscle can produce.

During THIS contraction, as the speed of contraction increases, the force of the contraction decreases.

During THIS contraction, as the speed of the contraction increases, the force of the contraction also increases

The patient is positioned in supine with the arm in 90 deg of abduction and 90 deg of elbow flexion. The therapist laterally rotates the patient's shoulder. A positive test is indicated by a look of apprehension or a facial grimace prior to reaching an end point.

The patient is positioned in supine with the arm in 90 deg of flexion and medial rotation. The therapist provides a posterior force through the long axis of the humerus. A positive test is indicated by a tool of apprehension or a facial grimace prior to reaching end point.

In standing, the therapist positions the patient's arm in 20-50 deg of abduction. The therapist then grasps the patient's elbow and pulls the arm inferiorly. Test is positive a depression seen between the acromion and humeral head is noted. This can be graded by measuring the vertical length of the depression (1+ for <1 cm, 2+ for 1-2 cm, and 3+ for >2 cm)
