Many people believe that some stretching sports with vertical jump such as basketball and volleyball can increase the body height. On the other hand, others do not agree with this argument.
The problem is that there are many scientific websites that have explained and discussed this issue but as I see, both of them don't refer to any scientific article with specific statistical experiments.
I just found this article that has not a regular scientific content.
I am pleased to answer this question with a scientific article.

Satyam Majergi - a postdoctoral fellow at Northwestern Institute says we have studied the effect of internal team relationships on team sports results. There were two aspects to measure these relationships: the first was a quantitative aspect represented by the number of times two teammates cooperated, and the second was a qualitative aspect that focused on the "prior joint success" among the team members, which helped us to know whether the teamwork succeeded or failed. In other words, we tried to study the chances of success of a team whose members have previous common experiences in the event that they encounter another team that includes highly skilled players.

Pressure air biofeedback is associated with strength testing in all population. Wheelchair basketball players posses different conditions associated with low-grade strength and power lumbar functions. Core activation has been shown to prevent the development and progression of severe lumbar malfunction. Does pressure air biofeedback and lumbar hypervolt vibration improve lumbar functions in wheelchair basketball players?
Relevant answer
Answer
I think the need for this concept has become less because the basket players on the chairs use their arm more than using any other part or support from another part. The best experience is to gain strength from the momentum of the move

For obtaining the acute-chronic workload ratio and make a comparison with the injury rate in a basketball season, i wonder which variable is better to measure for obtaining the data.
Relevant answer
Answer
Usually, the most reliable method for measuring acute chronic workload ration (A/C) is employing a repeated-measured days for an extended period of time, let's say 28 days. You would use the data to compute the load accumulated during the current week / load accumulated weekly over the past 28 days, by considering the internal variables and external variables. In regards to which external parameters to use will depend on your study, using tracking variables, often GPS-related, such as high-speed running and acceleration variables are all plausible options. Do consider the locomotor disadvantages in measuring A/C, thus considering maybe using various tracking devices or even the session-RPE method.
Hope this helps!

the youth strength training guideline established by the national strength and conditioning association recommends one to 3 sets of 6 to 15 repetitions for 9 to 12 years of strength training. each with appropriate weight load.
what is an appropriate weight?
in adults, some tests can be used like 1 repetition maximum (1RM) or even (10 RM) that represents the 100% of the participants then we can set the appropriate intensity according to the 100%.
in case of children strength training what stands for these measures?
Relevant answer
Answer
Intensity is defined as EFFORT. To quantify effort is subjective. Some have used Perceived Exertion Scales. I would recommend quantifying strength training by charting progression each workout on a workout card.

Plyometrics in Basketball.
Relevant answer
Answer
"Using sprinting performance as an example, exercises involving bilateral contractions of the leg muscles resulting in vertical movement, such as squats and jump squats, have minimal transfer to performance. However, plyometric training, including unilateral exercises and horizontal movement of the whole body, elicits significant increases in sprint acceleration performance, thus highlighting the importance of movement pattern and contraction velocity specificity"
"Further examination demonstrated that body mass-adjusted muscular strength is more highly related to performance measures than is absolute muscular strength"
"The training studies in the literature that have utilized traditional strength and power training programmes, which involved exercises being performed bilaterally in the vertical direction (e.g. Olympic-style lifts, squats, deadlifts, plyometrics, vertical jumping), have mostly failed to elicit improvements in COD performance. Conversely, the training protocols reporting improvements in COD performance have utilized exercises that more closely mimic the demands of a COD, which include horizontal jump training (unilateral and bilateral), lateral jump training (unilateral and bilateral), loaded vertical jump training, sport-specific COD training and general COD training"
" A significant increase in the passive component of the SEC stiffness was found (p < 0.05). In contrast, a significant decrease in the active part of the SEC stiffness was observed (p < 0.05). Thus, plyometric training led to specific adaptations within each part of the SEC. Theses adaptations could increase both the efficiency of the energy storage-recoil process and muscular tension transmission leading to an increase in jump performances"
"In the trained group, a decrease in dissipation coefficient (-35.0%; P<0.05) and an upward trend in stiffness (+24.1%) of the Achilles tendon was found. Plyometric training enhances the muscular tension transmission mainly through a reduction in energy dissipated by the tendon. The lack of changes in the Achilles tendon CSA indicates that changes in mechanical properties would mainly result from a qualitative change in tendinous tissues rather than from changes in the geometry of the Achilles tendon"
"The Ca2+ -activation threshold was not altered by training, but the Ca2+ concentration required to elicit half-maximal activation showed a decreasing trend, with significant changes in type I fibers (P < 0.001). Plyometric training increased single-fiber Ca2+ sensitivity, especially in type I fibers"
"Maximal shortening velocity was increased 18, 29, and 22% in type I, IIa, and hybrid IIa/IIx fibers, respectively (P < 0.001). Peak power was enhanced in all fiber types, and normalized peak power improved 9% in type IIa fibers (P < 0.05). Fiber tension on passive stretch increased in IIa/IIx fibers only (P < 0.05). In conclusion, short-term SSC exercise training enhanced single-fiber contraction performance via force and contraction velocity in type I, IIa, and IIa/IIx fibers. These results suggest that SSC exercises are an effective training approach to improve fiber force, contraction velocity, and therefore power"
"When subjects can adequately follow plyometric exercises, the training gains are independent of fitness level. Subjects in either good or poor physical condition, benefit equally from plyometric work, also men obtain similar strength results to women following PT. In relation to the variables of program design, training volume of less than 10 weeks and with more than 15 sessions, as well as the implementation of high-intensity programs, with more than 40 jumps per session, were the strategies that seem to maximize the probability to obtain significantly greater improvements in performance"
"Short-term PLY also improves the lower-extremity strength, power and stretch-shortening cycle (SSC) muscle function in healthy individuals. These adaptive changes in neuromuscular function are likely the result of (i) an increased neural drive to the agonist muscles; (ii) changes in the muscle activation strategies (i.e. improved intermuscular coordination); (iii) changes in the mechanical characteristics of the muscle-tendon complex of plantar flexors; (iv) changes in muscle size and/or architecture; and (v) changes in single-fibre mechanics. Our results also show that PLY, either alone or in combination with other training modalities, has the potential to (i) enhance a wide range of athletic performance (i.e. jumping, sprinting, agility and endurance performance) in children and young adults of both sexes"
"As compared with the performances before training, normalized EMG in the soleus were significantly (P<or=0.001) increased after 4 and 8 weeks of training. Tendon stiffness, elastic energy storage, release and jump height determined after training were significantly increased (P<0.05), with a concomitantly reduced voluntary EMD (P=0.01)"

Some researches have defined the instant of ball release as " Ball release was defined as the first frame in which the basketball left the  participant’s  hand. ". However, as I hadn't any marker on the ball, I can't use from this definition.
Please let me know, how can I estimate the instant of ball release in basketball free throw by some variables such as elbow and wrist angels ( the peak of extension of elbow joint and or the peak of flexion of wrist joint)?
I'm looking forward to see your informative comments.
Regards,
Esmaeel,
 
Relevant answer
Answer
Hi Esmaeel,
First, could you explain why you want to know the instant of ball release? Are you trying to compare with previous research? Or are you trying to answer a specific research question? How accurate do you have to be?
Second, could you elaborate on what data you have measured?
Frankly, I don't think you can reliably detect the instant of ball release if you only have joint angle data. Sure, you can estimate it happens at for example the the peak velocity of the wrist angle, but you will never be entirely accurate due to (functional) variability. Ultimately, you would have to validate your assumption that instant of release and some variable of joint angles are related.
Good luck,
Rens

We are researching on tactical performance in basketball with 4 observers, analysing both nominal/categorical and continuous variables. I have used Randolph's free-marginal multirater kappa (see the link attached, Randolph, 2005; Warrens, 2010) so far, but I would like to know which different kind of Inter-observers reliability measures do you know and why do you think could be more suitable when you have more than two observers. Thank you in advance.
Relevant answer
Answer
To mention other methods of inter-observer reliability measurements (could also be used for intra-observer reliability):
Intraclass correlation coefficient (ICC) is an assessment of inter-observer reliability which expresses the relation of explained variance to the total variance (in terms of reliabilty, the nearer to one, the better). Be aware that the exact description of ICC formula is needed, since there are several ways to calculate ICC. For further information I could recommend “Atkinson G, Nevill AM. Statistical methods for assessing measurement error (reliability) in variables relevant to sports medicine. Sports Med 1998;26:217e38.” “McGraw KO, Wong SP. Forming inferences about some intraclass correlation coefficients. Psychol Methods 1996;1:30e46.” “Shrout PE, Fleiss JL. Intraclass correlations: uses in assessing rater reliability. Psychol Bull 1979;86:420e8.”
Mixed model analysis is another sophisticated method to determine the explained variance in a more detailed way (thereof, ICC could also be calculated). For example it might be interesting how much of the variance can be explained by the basketball observers (the less the better, since a high explained variance by the observers means a greater variability of the ratings between the observers). For STATA users I could recommend “Rabe-Hesketh S, Skrondal A. Multilevel and longitudinal modeling using Stata. 3rd ed. College Station, Tex.: Stata Press Publication; 2012.”
