Building Standards for Evaluating the Strength and Speed ​​of Athletes of the Quang Ninh Women's Basketball Team

From the above results, it can be affirmed that the results of the selected tests all ensure a relatively standard distribution of the survey data in each test to evaluate the TĐTL of the Quang Ninh Women's Basketball Team.

Step 2: Build a scoreboard, a comprehensive assessment score for the Quang Ninh Women's Basketball Team.

According to the 2-sigma rule (2δ), the values ​​of the tests are divided into 5 levels: Good, Fair, Average, Weak, Poor as follows [7], [35]:

Good: > x + 2  .

Fair: > x + 1  to x + 2  .

Medium: From x - 1  to x + 1  . Weak: < x - 1  to x - 2  .

Poor: < x - 2  .

For tests where the test results have the smallest measurement possible, the above 5 levels will be arranged in the opposite direction. To facilitate the quantification of different contents in the process of evaluating and classifying training ability.

of athletes, the thesis classifies the results according to each criterion into 5 levels with the following convention:

Good rating: From 9 to 10 points. Fair rating: From 7 to < 9 points.

Average Rating: From 5 to < 7 points. Poor Rating: From 3 to < 5 points.

Poor Rating: From 1 to < 3 points.

The results are shown in Table 3.5.

Step 3: Determine the assessment score of the TĐTL through specific professional physical qualities.

The standards for evaluating the TĐTL are considered important criteria for athletes to self-assess their abilities as well as help coaches adjust and regulate their performance.

Control the training process to suit the training phase orientation for each individual athlete.

Conduct a scoring scale and classification table to evaluate the physical and technical criteria of the athletes of the Quang Ninh Women's Basketball Team using the C scale. Because, when considering the synthesis of many criteria with different measurement units, using the evaluation scale is convenient and appropriate [7].

To determine the level of achievement of each event, and each criterion of the athlete is established according to the C scale point system. [7], [35]

Based on the mean value ( ) and standard deviation (  ), calculate the score according to the C scale for each research indicator. The C scale is a standard scale because it uses standard deviation and the condition for establishing the scale is to have a sample set in the form of a normal distribution.

Step 4: Determine the total score of the TĐTL through physical and technical qualities.

From determining the scale of assessment of the TĐTL through the specific physical qualities of the TĐTL (pedagogy) athletes of the Quang Ninh Women's Basketball Team, it is possible to build a comprehensive assessment score table of the TĐTL (pedagogy) athletes of the Quang Ninh Women's Basketball Team with a maximum total score of 60 points and a minimum of 6 points. The determination of the gap in assessment scores between is as follows:

n

When evaluating the overall ranking of the TĐTL, the proportion of the component factors is not calculated due to the compensation rule between the qualities of each athlete.

When comparing actual performance with scores, use the asymptotic method, meaning that the score closer to the performance is allowed to be used as the evaluation score.

The results of the scoreboard construction and the summary scoreboard evaluating the athletes of the Quang Ninh Women's Basketball Team are presented in tables 3.6 and 3.7.

From the theoretical and practical basis, it can be seen that there are many standard scales for evaluation such as standard scale Z, standard scale C, standard scale T. In addition, in practice, standard scale H, standard scale B, standard scale E are also used [7], [35].

In the construction of the assessment criteria for the TĐTL of the athletes of the Quang Ninh Women's Basketball Team, the assessment was conducted according to the C scale because it is a commonly used standard scale and for easy comparison and contrast with related works. The construction of a summary score table for the assessment of the TĐTL of the athletes of the Quang Ninh Women's Basketball Team has proven that an athlete with good ability in this test may not have good ability in another test, because the abilities compensate each other.

The results of selecting criteria and testing to evaluate the athletes of the Quang Ninh Women's Basketball Team have ensured the roadmap [7], [35]:

Phase 1: Establish a rating scale (called intermediate rating).

Phase 2: Compare the established scale with the old criteria for a comprehensive assessment.

3.1.3. Evaluation of the current strength and speed of athletes of the Quang Ninh Women's Basketball Team

Physiological function criteria reflect the health status and the ability of functional organs such as respiratory circulation, oxygen transport and absorption capacity, and the speed and capacity of the body's energy supply. Good physiological functions reflect the higher the body's operating capacity [1], [24], [41]; [46].

The survey results assessing the speed strength status of athletes of the Quang Ninh Women's Basketball Team are the basis for proposing appropriate exercises in training to develop speed strength and long-distance shooting technique (3-point shooting) in particular of athletes of the Quang Ninh Women's Basketball Team in the deep specialization stage.

3.1.3.1. The current status of speed power from a biomedical perspective

To evaluate the speed strength of basketball players in training, it is necessary to quantify the internal components of the body, which are biomedical indicators, including morphology, physiology, biochemistry, and biomechanics; as a basis for determining the external manifestations, including pedagogical indicators of general physical strength, physical strength, etc.

The expertise, techniques, tactics and psychological qualities of each athlete at their peak, that is, before competition [1], [5].

In the athlete training process, the assessment of speed strength of athletes at all levels according to age, gender and specialized sport is very meaningful in terms of practice and theory, especially in sports selection and training. In particular, the application of medical-biomedical testing methods to study the structural and functional characteristics of body organs plays a particularly important role in assessing speed strength, which is closely related to the development of organs and organ systems of the body. To accurately assess the level of anatomical and functional development of the body's organs, athletes need to conduct both resting and moving states, especially the state of maximum exertion [84], [89], [96].

The values ​​of the morphological status and physiological function of the athletes of the Quang Ninh Women's Basketball Team are presented in Table 3.8.
