explan the class of physical fitness and its sub componts of physical fitness​

Answers

Answer:

The five components of physical fitness are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition, according to Fit Day.

Explanation:

Explanation:

The 5 components of physical fitness are often used in our school systems, health clubs and fitness centers to gauge how good a shape we are truly in. The 5 components that make up total fitness are:

1.Cardiovascular Endurance

2.Muscular Strength

3.Muscular endurance

4.Flexibility

5.Body Composition

Total fitness can be defined by how well the body performs in each one of the components of physical fitness as a whole. It is not enough to be able to bench press your body weight. You also need to determine how well you can handle running a mile etc.

1.Cardiovascular endurance is the ability of the heart and lungs to work together to provide the needed oxygen and fuel to the body during sustained workloads. Examples would be jogging, cycling and swimming. The Cooper Run is used most often to test cardiovascular endurance.

2.Muscular strength is the amount of force a muscle can produce. Examples would be the bench press, leg press or bicep curl. The push up test is most often used to test muscular strength.

3.Muscular endurance is the ability of the muscles to perform continuous without fatiguing. Examples would be cycling, step machines and elliptical machines. The sit up test is most often used to test muscular endurance.

4.Flexibility is the ability of each joint to move through the available range of motion for a specific joint. Examples would be stretching individual muscles or the ability to perform certain functional movements such as the lunge. The sit and reach test is most often used to test flexibility.

5.Body composition is the amount of fat mass compared to lean muscle mass, bone and organs. This can be measured using underwater weighing, Skinfold readings, and bioelectrical impedance. Underwater weighing is considered the “gold standard” for body fat measurement, however because of the size and expense of the equipment needed very few places are set up to do this kind of measurement.

do you believe that men and women have perform specific roles?​

Answers

Answer:

I, personally, believe that both men and women have performed specific roles throughout our history. There are many gender/sterotypes that we categorize both genders into. Gender roles are defined by the attitudes, behaviors, and even values. One major one that is still looked upon today is: men doing all the work, bringing money to his family while his wife stays home and cleans, cooks, and even takes care of the children and their everyday needs.

Answer:

I would help with her wish especially if it is legal to do so in the state we live.

Explanation:

There have been arguments that people should be allowed to die in whatever way they choose to go. And others should be able to help them carry this out.

Answer:1.A,2.B,3.B,4.C

Explanation:

You work in one of the eight schools in your district. Each school in your district serves the same cafeteria food. A few parents have expressed concern to you about the lack of fresh produce in school meals. You know that colleagues of yours have also heard similar feedback from parents. 1. Knowing that there were likely many factors and/or people involved in creating the current lunch system, what would you do to address the concerns parents have raised

Answers

Answer: Call a meeting, and possibly write to the major or local government chairman to handle it

Explanation:

One of the first things I'll do is to get in touch with the authorities serving the food and lay a complain about what's happening about the complains, then I'll also seek the permission of the school body to discuss with the parents and apologize to them all for the poor services. If after calling on the authorities responsible for food to sit up and they don't, I would write a letter to the district head or mayor of the town for the situation to be looked into and propose sanctions so it'll be taken serious.

To address concerns raised by parents about the lack of fresh produce in school lunches, it would be necessary to engage some authority to discuss a solution to this problem.

The ideal would be to first bring together the eight schools in the district that also heard complaints about the food served to students, and then form a committee to take the case to the responsible rulers.

Importance of healthy habits at school

It is essential that students can receive healthy food at school, so that positive habits of preservation and maintenance of health are learned and passed on.

Therefore, it is essential that there is social and political adherence to the need for healthy and fresh school meals.
