The physical fitness test of college students lasted for one minute, with 26 freshmen and 26 sophomores passing and 27 juniors and seniors passing.
College students only have sit-ups for girls 1 minute, and each student is assessed once every academic year, which is recorded in the National Student Physical Health Standard Registration Card.
College students 1 minute sit-up test standard;
Before the test, the subjects crossed their fingers behind their heads, their legs were slightly apart, their knees were bent 90 degrees, and they lay on their backs on a flat mat. Another companion pressed both ankles of the subject to fix the lower limbs.
Subjects must repeatedly hold their heads in their hands, tuck in their stomachs, and make their trunk sit up straight. After the elbow touches or exceeds the knee, return to the starting position and continue to exercise 1 min.
When the tester issues the "start" password, the meter starts timing; Record the number of sit-ups completed by the subjects within 1 min. Take "times" as the unit.
After hearing the "start" command, the subjects put their heads in their hands and abdomen in order to complete the sit-ups on their trunks. After the elbow touches or exceeds the knee, return to the starting position and complete a sit-up.
Skills of doing sit-ups for college girls;
1, cooperate with breathing.
Reducing the stomach needs to cooperate with breathing, and the muscles of the lower abdomen will become tight to achieve the effect of reducing the stomach.
When practicing: exhale in the ascending state (when exerting force) and inhale in the retreating state. Be still, for example, keep an angle of 45 degrees, keep normal chest breathing, and don't hold your breath.
Usually: Abdominal breathing helps to tighten the transverse abdominal muscles. When inhaling, feel the abdominal cavity lift inward and upward, and exhale deeply after inhaling fully. When you sit, stand or walk, you can consciously take abdominal breathing and form a habit.
Don't hold your head with your hands.
According to the normal understanding, when doing sit-ups, we cross our hands behind our heads, and then when sitting up, we use the strength of our hands to drive our bodies upward.
Although this is very scientific, it is easy to cause neck strain and the exercise effect will also decline. So when we do sit-ups, we can put our hands on our chest.
3. Rise height: keep an angle of 45 degrees.
Many people blindly believe that the higher you get up when doing sit-ups, the better the exercise effect will be. Actually, this is not right.
When we get up, we only need to keep a 45-degree angle, so that the abdomen can be squeezed better and the slimming effect is better.
4. The speed is right.
Many girls think that the faster you do sit-ups, the better you lose weight. In fact, the faster the speed, the less pressure on the abdominal muscles. The correct way is to slow down as much as possible and exercise the control ability of abdominal muscles.
The most correct speed should be to get up faster and go down slowly.
