Ask Biostatistian

You can observe the acute and chronic effect of high intensity interval training or a varied intensity workout for a period of time on the following physiological parameters: HR, RHR, BP, VO2 max, lactate, etc.

A researcher’s best statistical analysis software is the one that satisfactorily addresses the statistical needs of their investigation and lies within their financial affordability and technical ability. That pointed out, the most widely used statistical software platform in the social sciences is IBM SPSS Statistics—albeit not for free. Alternatively, jamovi is a good option for those seeking an open-source package with a similar interface to SPSS. Here is an article that you might find helpful on jamovi.

Good luck,

There is a range of software, depending on your discipline and the type of data you are collecting. Currently in social and beahvioural sciences, the preferred software packages are STATA and also R. However, SPSS is also a good package but expensive to purchase. R is free. Excel is also available as part of Microsoft Office but its statistical capability is not as good as some of the others.

If you are collecting qualitative data then packages can include Nvivo, Atlas, Maxqda, among other.

Hope this is helpful.

A severe deficiency of vit D (below 25 nmol/L 25OH vit D3 in serum or plasma) causes loss of muscle strenght.

For athletes the optimum lies above 75 nmol/l, maybe even above 100 nmol/L being the natural status in rural living African people.

Read our publication about vit D and professional soccer players :

Thanks for your opinion Paulo. Yes, probably some problems could emerge from a overuse of this SSGs in the tecbical- tactical and physical fitness preparation. We would be interested in perform an study about is effect on disbalance between agonist / antagonist muscle and fatigue due to overuse of this methodology in your football players. Regards

To improve flexibility, it is necessary to lengthen, stretch the constraint structures that limit the range of motion of the joint during various stretching exercises. The viscosity and elasticity properties of these constraints allow permanent deformation, thus increasing the resting length of the tissue. It would be essential to be able to use the flexibility measures that can identify the factor, or the limiting factors, both general and specific, so that the interventions are appropriate. Improper use due to joint injury.

Limitations on the flexibility or range of motion of a joint can be active or passive. Active limitations involve only the muscle-tendon unit, while passive limitations involve the anatomy of the joint, capsule, and ligaments, as well as structures such as the articular meniscus (Stanish et al. 1990). It is important to define the limits of flexibility as accurately as possible, as this will influence the selection of exercises, such as stretching or stability exercises.

Dear Hamidreza Khalounejad , there are various types of modalities that can be beneficial for persons with MS.

I have explained all types with detailed information such as volume, repetitions, exercise selection, etc particularly during COVID-19 in my latest article, which you can find it here:

Dear Pegah Jamali , According to force-velocity curve muscle contraction, Muscles are capable of generating greater forces under eccentric conditions than under either isometric or concentric contractions. (1)

To understand how eccentric exercise produces more force and how it can help to prevent injuries, you should know the mechanism of that, which I have explained in my article

1- https://www.sciencedirect.com/topics/medicine-and-dentistry/eccentric-muscle-contraction

Resistant exercises can tire MS disease quickly. This is an undesirable situation in patients with MS.

I recommend more ROM exercises and short-term isometric exercises.

The best MS exercises are aerobic exercises, stretching, and progressive strength training. Aerobic exercise is any activity that increases your heart rate, like walking, jogging, or swimming. You just don't want to overdo it—it should be done at a moderate level. https://www.pennmedicine.org/updates/blogs/neuroscience-blog/2017/may/multiple-sclerosis-and-exercise

I recommend the Biomedical Human Kinetics journal, many authors cite interesting sources! It is worth entering into google scholar

Try International Journal of Sports Science & Coaching

I would agree with your view. I do think, however, it depends on the level of the student and the intent of the program. I have used it within our graduate level Exercise Science program where students are required to do research and strongly encouraged to publish.

Please go through our article "Aging induces a step-like change in the motor ability structure of athletes ". If you are interested in a change in motor performance.

Sport science studies always are encountered with this problem. Along with ergogenic aids, many other confounding variables can also affect the results of sport science studies. That's why recently it was mentioned that more than 90 percent of the sport science studies results aren't reproducible. It's mean that if a group of researchers conducting a study and publishing their result and any research group in another country want to conduct the same study, there is just less than 10 % chance that results of them being similar to each other. and we can not translate the results of a sports science study with a small sample size to other groups and the results of that study are just valid within participants of that study.

Uday CH Hasan, I'm sorry if this disappoints you, but there are more than 6,000 citation / referencing systems, with possibly around 2,000 (maybe more) that are of the author-date (i.e., Harvard) type that yours seems to be primarily based on.

Unfortunately, I can't tell you which of those two-thousand or so Harvard systems is the one you are seeking - a system that strikes me as being quite unusual because it combines alphabetic with number sequencing. I wonder, therefore, whether it might be easiest for you to work initially with a "good" author-date system and then add the numbers to the reference list entries at the end.

Whether that works nicely or not might depend on how you indicate citations in the body of your text. If you use an author-date system in the body of your text, the numbers can be inserted into your reference list entries at the end of everything.

If you work accurately, that could be achieved, I suspect, in about 10 minutes (or less) for about 30 reference list entries.

Sometimes doing things manually takes a lot less time and effort than trying to work out how to do things with automation.

Incidentally, I have put an article about referencing under my name onto RG. I'm aware that article is a little outdated by now (e.g., because I refer to the APA 6th, not APA 7th, system of referencing), but it might be helpful.

Dear Colleague,

I just started to collect data on exactly this topic as part of a more comprehensive meta-research study regarding orthopedic and sports medicine literature.

I think right now, most studies with a medical background pre-register in classic registries for clinical trials like clinicaltrials.gov or the german equivalent DRKS. Regarding studies without medical background, I would say OSF pre-registration formats are more common and I expect that the proportion of registration and preprints in STORK will increase in future.

Best,

Robert

It is reported that there are many "RR type" players in measurement items that require instantaneous power such as back muscle strength and long jump.

Thank you. That is very helpful.

Great, thank you. I'll send you a message.

Please take a look at these useful RG links.

Your answer is a straight one - increased exercise will increase GH levels and increase muscle mass (assuming you are not consuming excess calories that need to be converted to fat) but GH will also decrease fat deposition. It changes body composition. Look at transgenic pigs with extra GH - lean with virtually no fat. Look at cattle with GH administration - fat stores are preferentially tapped for energy and milk production. Sprague-Dawley rats (fed a moderately high fat diet diverge into 2 populations - obese and obesity resistant. The resistant (i.e. lean) rats have a higher GH production than the obese rats (this is before the diet was fed). So GH was actually protective in this model against obesity. There is lots out there. I had an NIH grant 20 years ago looking at this.

Hi,

Adding to Mr. Warren's reply, it is stated by this document also;

---

"How does the system know the lever length of the adapter shaft for calculation of torque?

It doesn't and is not required as torque is a rotational force measured at the axis of rotation. "

--

Actually you can have same torque by different forces with different lever lengths, (FxLever arm could be same) . Hence your question is actually relevant for two persons having different limb lengths, i.e. same torque could be produced with lower force with longer limb.

Hello!

We have recently published a systematic review (PMID: 30929281) studying methodological consideration related to MFO and Fatmax. It includes all papers that have assessed MFO including details about the MFO protocol. I think It could be useful for you.

Perhaps I should have been more specific concerning "relative", or not: the replies I got opened a richness of possibility. What I had in mind was the traditional: "1 repetition max, regardless of body weight" X "lifted weight by body weight through specific coefficients (Wilks, Glossbrenner, Reshel, Schwartz/Malone, Siff, NASA)". Francesco Cuzzolin , your index is a coefficient I have never seen used. It sounds very interesting concerning the recent discussion on the relative importance of femur length and body weight on the squat. Sebastian Sitko , I believe relative strength and power are the only measure of these phenomena that come closer to reflecting something of interest. The literature is unclear on that, though.

Hi Iordanis Vasileiadis

I don't know if this help you completely, many works use the Vineland Adaptive Behavior Scales (VABS) for some domains as, comunication, daily living skills, socialization and motor skills. If to help, reach the link below.

I hope this helps.

Thank you guys. I found a partner (on the other side of the world).

It is now published

eccentric -> mostly in force there is contribution of passive elements, and less of active elements (cross-bridges). Because of lengthening the "damage", which is more in reality sensing of receptors leads to, generallly, addition of sarcomeres in series. So lengthwise the muscle cell will grow, and in parallel some addition can be done because there is some activity of myosin-actin.

In case of drop set, there is more fatigue, and you keep training with lower intensity or load, but because of higher fatigue, you keep on getting more higher or highest threshold groups. Also there is both eccentric and concentric work done, so more addition of parallel sarcomeres (at least in theory).

With the eccentric training the question remains how soon or how many highest threshold groups are involved as the passive elements can contribute a lot towards the force production. It might be that less high(er/est) threshold groups are activated. Eccentric training can be done with overload, as in very heavy weights only eccentric, with less voluntary control. Or with for instance a bit more load which can still be controlled.

Eccentric has more muscle damage related to intensity, because of higher loads, while drop sets have less high loads and more fatigue, so there would be in the first, hypothetical more mechanical damage, and in the second more metabolic damage. However, the question is open if muscle damage contributes to HT in the first place.

So drop set with controlled eccentric movement in the exercise might be better for overall hypertrophy as you train both eccentric and concentric.

This answer to the auestion "Is sport science about individual holistic approach, or inter-individual reductionistic specialism?" comes from half a century of research experience, with my first scientific paper having been published in 1969. Wholism and reductionism are labels for formalistic conceptions that may exist in the conceptions of sport philosophers but rarely if ever comprise useful frameworks for research. At the outset of any research problem one rarely knows all of what will be needed to answer the question, and must add new knowledge as one moves along. Far more than first knowing all of what may be needed is choosing the most important problem that one has a reasonable chance of solving (i.e. working in the "Medawar Zone" as it has aptly been termed.

Which project are you interested in as I have several?

Good afternoon!

It is important to understand how homogeneous the study group is and whether it will identify the links between the types of exercise and dietary characteristics.

If in the studied array it is possible to single out established groups, then it will be sufficient to have 20% in them, selected according to significant criteria. If the array is very diverse in characteristics, then all

Some of the challenges confronting sports entrepreneurship emanates from governance issues, stakeholders conflicting interests, source of entrepreneurship in sports especially in contexts where government with its inefficient bureaucracy is providing major funding, political interference with sports entrepreneurship as is the case with the present NFL debate in the US, how far will profit which is the reward for entrepreneurship be emphasized in sports, international politics in sports entrepreneurship as with the likely threat of North Korea and the next Winter Olympics in South Korea among many other contending challenges. But in the midst of all these, these challenges will combine to strengthen the emergence of stronger sports entrepreneurship. This will be consistent with the strategic orientation of entrepreneurial emergence which portends that entrepreneurship is defined and fashioned by ability of entrepreneurs to record success in the Face of obstacles. 

Hi I have a longish paper on this coming out in the next few month in the Journal of the Philosophy of Sport: it's called:Therapeutic Use Exemptions and the Doctrine of Double Effect.  The anwer isn't nearly as simple as other answers suggest. it depends on the role of intentions in both the morality of, and the regualtion of doping.  There's a signiificant tension between Wada's approach to TUEs and the principle of strict liability.  The two are inconsistent.  I favour an approach which takes account of intentions - as is common in most moral theory and most jurisprudence.

Hello,

In stable position like in chess playing the EEG record may be quite good. Problem starts when you try to record EEG while moving. We used to try to record EEG during simple movement: squat, staying in squad position, flexing in elbow. Unfortunately the record was completely unreadable. The signal was full of artifacts. 

I came across this instrument which is a clip-on, so easy to use with existing gear. https://www.motionizeme.com/

It doesn't measure force, but if you integrate the data (and video) with good real-time speed measurement (so you get the change of velocity during the stroke), the 'skeptical young guys' will be able to observe the impact of changes to the stroke.

Yes, indeed Alfred!! Thank you for highlighting my error! Definitely not the first 2 minutes!!! the process outlined by Alfred I would agree with. I think the intensity of exercise you are looking at and/or what modelled parameters you are interested in could influence what model you use. If intensity is below GET, or just interested in MRT you could use a mono-exponential model, everything else bi-exponential. 

Not sure if a minimum age range was ever established for the NASA-TLX; the original guide document has not made reference to this. I'd be interested to hear if anyone has any information about age-ranges for use.

If you have the means, SD and n for each group, you can easily include that in a meta-analysis in CMA.
