Question

1. При статической работе мышц человека, в отличие от динамической — . А — работоспособность более продолжительна. Г — быстрее наступает утомление. З — движения в суставах не происходит. М — сокращение мышц чередуется с расслаблением. У — утомление наступает медленно. П — уменьшается частота сердечных сокращений. 2. При динамической работе — . При статической работе — . Г — сокращение мышц чередуется с расслаблением. Р — движения в суставах не происходит. З — работоспособность более продолжительна. К — утомление наступает медленно. У — утомление наступает быстрее.

Answer 1

При статической работе - а,з,у,п
При динамической работе - утомление наступает быстро, сокращение чередуется с расслаблением, быстрее наступает утомление

Answer 2

Static Work of Muscles

When it comes to the static work of muscles, there are several key differences compared to dynamic work:

1. Work Duration: Static work is characterized by longer-lasting work capacity, meaning that the muscles can sustain the effort for a longer period of time.2. Fatigue: Fatigue sets in more quickly during dynamic work compared to static work.3. Joint Movement: In static work, there is no movement in the joints. The muscles contract and hold a fixed position without causing any joint movement.4. Muscle Contraction: In static work, muscle contraction alternates with relaxation. The muscles contract and maintain a fixed position without any movement.5. Fatigue Onset: Fatigue sets in slowly during static work. The muscles can sustain the effort for a longer time before fatigue becomes noticeable.6. Heart Rate: During static work, the frequency of heart contractions decreases.

Dynamic Work of Muscles

In contrast, dynamic work of muscles has the following characteristics:

1. Muscle Contraction: Dynamic work involves alternating muscle contraction and relaxation. The muscles contract and relax in a rhythmic manner to produce movement.2. Joint Movement: Dynamic work involves movement in the joints. The muscles contract and relax to produce joint movement and perform tasks such as lifting, pushing, or pulling.3. Work Duration: Dynamic work has a shorter work capacity compared to static work. The muscles fatigue more quickly during dynamic work.4. Fatigue Onset: Fatigue sets in more quickly during dynamic work. The muscles tire faster compared to static work. It's important to note that the information provided here is based on general knowledge about muscle work and fatigue. Individual factors, such as fitness level, muscle strength, and overall health, can also influence the specific characteristics of muscle work and fatigue in different individuals.
