第 12 章 - 姿勢、動作和表現評估 (Chapter 12 - Posture, Movement, and Performance Assessments)

So we move from the overhead to the single leg squat now the single leg squat is not for everybody but if a person has scored well on the overhead squat or you know if a person lacks balance we might not want to throw this at them we want to just make sure that we put these people in the prime location and the prime positioning so they can do it correctly so if they have a hard time with balance or if they have a hard time getting into that single leg squat position in general then we would avoid this and move on which is the single leg squat it's not optional but it can be it's one of those ones where we'd rather do the overhead squat as the priority versus the single leg squat okay so the single leg squat there's your starting position all right looking at squatting down in a single leg position so this is why balance is really important hands on the hips stable surface again making sure that the other leg is not any more than six inches off the ground you don't have to be too far like you don't have to lift your leg too high it can be just about six inches off the ground and that's gonna then get your squat as deep as possible now you will see a slight bend or a slight angle change but we're more looking about the knee and the lower ankle because that's gonna dictate the the bad positioning per se all right again five repetitions then you switch sides see if there's any difference between them same thing as before shoes off is optimal okay if they can't then so be it so there's the deviation that we were explaining the knees and the ankle are getting a little aggressive on this one here so that's gonna be the common impairment impairment here which we would call again knees flaring in would be knee valgus so you know there's your you know that's the check there's only one really major checkpoint for this and that is from the anterior position and it's the knees bowing in which is knee valgus is it one or the other or is it both okay because we want to make sure we know what and then at that point what we were to do is find our solutions chart find out what's over or under active and then we could go from there and make the right adjustments as needed so again make sure you know your overs and unders you know if from the anterior view you're the reason why the knees are caving in tight you know tight TFLs tight adductors and then you also have you know weak glute maxim medius and weak anterior and posterior tibialis muscles so you know one view only for that so that one again it's it's a little tricky to observe but it's worth observing if the person can handle it so then we move to our pushing assessment which is more like a standing chest press with a with a little bit of a staggered stance okay so again this one is making sure that we see not only scapular you know shoulder blade and total shoulder mechanics but we're also looking at the stability of our our hips we're looking at the stability of our cervical spine and then are also our head for that positioning as well all right so again moving through making sure that they're the all reps are taken care of because you're gonna do again more than one rep if needed so there's their starting position all right now the person's positioning with the you know their hands is just it's you really want to think about it being about chest chest level so this person might be a little bit higher but they could come down just a little bit if they needed to but this is an optimal position for starting they are going to complete the staggered stance positioning for 10 reps now the weight does not have to be challenging it could be just below challenging but we're looking to see that even if the weight is lighter they're still gonna if there's any compensations that they have during these lifts you're gonna see them even at a light to moderate light weight okay so as they push through all right again this person has a nice nice posture we're looking at where the handles are going are they going straight are they going up down etc making sure they're going slow and again five reps then five reps so again if you go back you see ten reps but it's ten reps total five on the right or five on the right foot forward and then five on the left leg forward because that may change up how they their their imbalances show so what we're looking for is a few different things because it's not the same as the overhead squat or the single leg squat because this is more upper body base where we are looking for that rounding back which we saw earlier we are looking for a shoulder elevation now shoulder elevation kind of like you know as they push out they shrug their shoulders that is actually quite common and some people might actually do that because they thought that that was the right way that this exercise should be you know completed and so over years of time even if they are an active exerciser we want them to understand that we can't have the elevated shoulders that's not the purpose of this we want to if we elevate the shoulders we take off that that isolation of the chest okay and then the other part is if the head juts forward okay so those are three indicators pushing assessment nothing from the everything from the lateral and the same things in a carry over to the pulling as well so there's your your checkpoints okay looking for those impairments do we have them or not from there we would say okay what can we do there's our overactives for our low back arch okay hip flexors lumbar extensors then the under actives glute meat glute maximus hamstrings and the abs so again again this carry over from you know the the overhead in the single leg squat you know from some of the things you might see with them there is your again your lateral view for both the elevation of the scapula and the head head forward or head jutting forward positioning so again pay attention to those overactive under actives know them because you may see them come up on your test pulling opposing nature same idea okay same idea same positioning just instead of pushing the weight forward we're gonna be pulling it back the same premise 10 reps you can go a little bit for this one here we want that wide split stance but again it could be narrowed up if they have a little bit of a little bit of a balance issue all right and then just pulling forward just like we would 10 reps slow and controlled 5 on the right leg forward 5 on the left leg forward or vice versa and then we're looking for the same impairments lower back arching scap elevating and forward jutting head similar with the you know the observations on your on your chart or one you might create yes or no and then same thing we're looking at where you they're probably gonna be more than likely the same over and under actives for each one right so but again just pay attention to your over actives and under actives and see where the mechanisms are for that and then we know again what to correct what to stretch and also what to strengthen all right so moving from those again are there there's still static positioning even though there's a dynamic movement there's still we're not going in motion we're staying static but doing a movement so now we're gonna get into the performance assessments which have a lot more of that dynamic appeal they are a lot of them are a lot of common you know motions that a lot of us have done in our lifetime all right so looking at the right side there the push-up test the bench press the squat assessment vertical jumping long or broad jumping the left test which is what we call the lower extremity functional test the 40 yard dash and our pro shuttle all right we'll go through each one of those so your push-up tests very common around a lot of testing facilities very common for you know the army very car you know or any you know service for police firefighting they all work around push-up testing even children in the PE classes okay so there's your positioning all right working on that solid push-up position hands let you know should be slightly outside of the shoulders they should be stacked you know on top of each other elbows and knees fully extended that are neutral and then you're gonna work on moving that down and up the client lowers their body to achieve 90 degrees of elbow flexion all right and then it says you're gonna do it for 60 seconds the main purpose here assessing for upper body muscular endurance okay and then like it says here when's a good time to reassess four to six weeks you know reevaluate your to reevaluate your program and see how it goes the bench press all right bench pressing we know about bench pressing and how it's basically the inverse of the push-up or it's gonna be lying down versus you know on our hands all right so we're gonna be lying down this one here is gonna be more about a one repetition max so we're gonna be assessing maximal strength this one again this is another one that we want to think about do is this really appropriate for our clientele it really can be appropriate for everybody but understand that in this case do we really need to do it for a particular person or could we do it for reps and and find you know so there's a lot of what we want to use it for okay but make sure that we also know that a spotter is going to be required so take a look at the positioning for your starting and then we'll move from there so you know again you can have assistance of unracking the bar okay and that's that's appropriate but then once you you count it off together three two one one two three however you want to do it and however they want to hand it off and then from there they're gonna handle that weight and then they'll re-rack it all right take their warm-up sets accordingly take at least two minutes of rest don't be afraid to go three to five minutes of rest as you move into the heavier weights especially with a more active person and then from there you can make five to ten percent jumps if needed or as you start getting heavier it might be less than five to ten percent jumps but understand that you're really looking at you know really you're looking at three attempts that we're looking for there okay so very very important for that definitely looking at trying to you know again looking for that maximal strength squat strength is the same premise as the bench press same thing except now we're getting into the proper positioning of you know where should that person be in in terms of where's their line of pull you know and on their muscles are they engaged the correct way in terms of you know where is it that they're going through you know through the range of motion and are they hitting that depth that we need to because we want to think that in terms of depth we really want to think about how again femurs parallel female femurs parallel or lower okay 90 degrees of hip is optimal for most people but if some people can go lower than that that is you know and it's and they're maintaining their posture I am NOT opposed to them going lower especially if they are doing it for specific reasonings okay so that's really critical for that now when we look at you know the squat itself we really want to think about how the barbell sits depending upon what kind of really the barbell wants to sit on those upper traps we want to think about bringing the elbows back slightly to create that little shelf for the barbell okay and then from there we want to think release the hips and the knees almost simultaneously but it's never the knees first okay more of an upright chest not you don't want to have an exaggerated lean forward all right so we want to be always neutral with low back okay trying to maintain optimal foot positioning that will translate into optimal knee positioning and that will really make it so that we go to the right motion so again you can help a person come off the rack but really it's safer for them to do it themselves all right go ahead and do your assessment you know and do your reps and then go ahead and take your rest as needed and then you can add load as needed they say 10 to 20% of the initial load all right and then go from there to add accordingly because again it may not be in 10 to 20% increments as you start getting super heavy three attempts you know to try to get the maximum amount of weight you can all right and then from there you can go into like it says there you can go into what they call the appendix a and calculate that person's one rep max if you were to do a three rep assessment but if you have a person trying to achieve a one rep max whatever they get is their max strength so vertical jump using what we this is actually a vertex device all right it's with the little little bars here that you're trying to hit so again that person is going to set up underneath what you will do is you will set up that person to their standing height okay so what you do is you have them stand tall you have them extend one arm up in the air without overextending and not lifting all right and then from there what you do is you would drop the vertex down to the bottom bar would touch their top of their finger at that point they would have to jump up as you know squat down jump up as high as they can and swap their hand to hit those bars at the highest level now if a person is say working with an athlete who you know has a very high vertical jump or you're working with like a powerlifter or an Olympic weightlifter and we know that they're gonna be able to go because go above 24 inches because that's the max that you can get on those bars then we can adjust this standing height here by adding things like from where they're standing height is adding 12 inches that because this little pole here that comes up and down that you adjust actually has indicator lines of inches that you can do okay so that's where we want to be able to take us through go and pressing forward with that okay and then they squat down slightly and then jump up as hard as they can explode up off the ground and then like I said squat squatting pressing through and swiping their arm to get the highest height reach that they can the long jump on the is going out versus up same premise explosiveness horizontal this is horizontal power where the vertical jump is vertical power okay that very big on performance indicators so same thing here like it says they want to use a tape measure and what you want to do is be able to you know have your line marked where they're gonna jump from that person starts behind the line gets it to that slightly squatted position it's a two it's a two foot jump and a two foot land so however far they need to squat down you don't want to you know you want to be explosive so you don't want to do a full squat and then jump out you want to think about bending down again optimal positioning with the hips hinging and the knees bending slightly and exploding off of the you know they say the heels of the foot but really the whole foot to be able to explode out and up or more out than up though but you want to still be off the ground all right from there three attempts just like you would with the with the vertical jump and the score would be the highest one you would get and then assess as needed okay so jumping out and then that tape measure from wherever they land all right wherever they land now if they land on two feet and then they fall a little bit forward it still goes by where the the heel landed first so sometimes this is really good to do in like a sand pit if you have one because you can see where the feet land other times you might have to say okay you're gonna have to redo that one because you have to be able to land and then be able to stand up from where you are to get the right distance traveled the lower extremity test or lower extremity functional test or the left test is where we would have two cones set up about 10 yards apart okay so about 30 feet and what you're gonna do with them is you're gonna have them go in multiple directions so if you look a through G those you have they have to do it in that manner so starting at cone one so if we're over here on the right side we want to think about starting here we're gonna sprint forward we're gonna back pedal back we're gonna side shuffle one way side shuffle back okay so now we're coming now from there a karaoke now karaoke's or karaoke's those are where the forward foot crosses over the back foot and then behind forward and behind all right and then lastly you would finish off with a sprint and then that would complete your time for how long it took you to do the one two three four five six seven different positionings throughout that whole time so really if you think about it that's 210 yards total coverage excuse me 70 yards 210 feet covered over the course of a very short period of time so again this is could this can be for many different people but again think about who the right clientele and the right demographic this would be for 40 yard dash assessment again who is this for because we want to think about you know what is the whole purpose of this it's acceleration it's reaction and it's actually maximal sprint speed how fast you go from the start point to 40 yards okay so once once that and basically how it works is as soon as that person makes their first movement you start the stopwatch as soon as they cross the line you end the stopwatch and it's their fastest time of how many particular trials you want to typically you know the first one is always the best but a person might just be getting warmed up so you can have them do like a couple of 40 meter you know 40 40 yard dash runs as quick as you know as not as quick as possible just to kind of ease into the flow and then they say okay now you have one attempt to get it done as fast you can so just it's up to you on how you want to achieve that but again it's the fastest sprint speed of that 40 yard distance the pro shuttle is gonna that this is a combination of many different things acceleration deceleration agility and then control and what it is you're gonna have three cones though you're gonna have three cones that are set up 10 the middle cone is the middle so the two end cones are 10 yards apart the middle cone is 5 is halfway so 5 yards in the middle and then from there what you would do is if you follow the arrows starting in the middle cone you're gonna sprint to the right as fast as possible tap that cone sprint all the way to the left cone tap that cone and then you will run through and run through the middle cone and so from the first movement tap the first cone tap the far cone run through the middle cone and whatever time you're you run through that middle cone is your final time so you're gonna go 5 yards 10 yards 5 yards that's why it's called the 510 5 or pro shuttle drill so very quick very explosive is a lot of speed up slow down and that really is one of the things that is gonna make this time faster or slower and very dependent upon that is whether you are you know you can slow down speed up as fast as you can all right so again regular regular testing on this to be able to get us to show what we're really you know whether we're making improvements especially if this is a really important one for athletes in particular but again you can always work with any other you know client that you want to performance based ones again can be worked with whoever you want to because again it's your assessment for your general fitness for weight loss goals whatever but again if you're doing it for weight loss this probably isn't a test that you want to do if you're doing it but you know for general fitness probably not the test you want to do but if you want to you know a person wanted to show that their performance is going up just for themselves then go for it but if it's you know weight loss isn't really going to affect this here because it's more performance based so that's the end of our performance based testing so what we want to make sure of again is what is the order of our sequence here and really the main thing is this bottom chart we want to do our paperwork first our pre our pre participation screenings we then want to do our physiological assessments we talked about those that is your heart rate your blood pressure and your you know your heart rate in your your blood pressure are the main things you can do things like breathing rate and things like that from there you'll go to your body comp okay BMI and body comp you can then go into your posture and movement assessments into your cardio assessments and then your performance assessments this should be the transition points on how you want to do it if you're going to do it all in one day okay but remember this sequence it's fairly important because it's going to be put on to your test for sure they want to know the sequencing of that okay that's how we get people in that's how we sequence our assessments that's how we get appropriate non skewed results so again be very aware of your clientele we talk I said this a lot throughout but overweight and obese considerations and modifications all right make sure that their pre participation screening is complete you know don't assume that just because they're and this is no disrespect to anybody but just because your person is larger overweight or obese does not mean that they don't have any ability and that's really a bad assumption to make because people are gonna be surprised when it's like I didn't realize they could do that but that's such a horrible thing they have to say because you went in with preconceived notions so don't do that okay it's very important not to do that and then really the main thing here like it says consider limiting movements that require someone to get up and down so if you're gonna do something like a push-up test you don't want to keep following that up with an up and then a down because it's hard for them to maneuver okay so how do we modify change up the depth of their overhead squat assessment don't do the single leg squat assessment okay that's gonna you know really hurt that but if they show proper strength and let them try it all right have them do a pushing or pulling assessment in a two foot stance versus a staggered stance okay have them just stand so that or for whatever is more comfortable for them but again don't assume make sure that you know what they can do with youth on the other hand you know youth can do a lot of things that we sometimes you know they're not little adults but at the same time they're also plenty capable of doing a lot of things just be aware that trying to give them like a one rep max assessment may not be appropriate so we might want to think about considering that all right but you know again that single leg squat if they're very iffy on their balance and coordination we might not want to present that to them all right so how do we modify do your instead of max strength do muscular endurance do more reps than we would for versus a one rep max test okay the other thing about it too is don't be afraid to to do the push-up test the left test the pro shuttle the vertical jump because they're fun okay children like them and they actually will you know if you make it more entertaining for them they may achieve better results versus making it like burdening for them older adults again know your people all right so but again don't don't let just because they're older doesn't don't let their ability cloud your judgment or your your judgment cloud what their ability level really is all right so we just want to make sure that again up and down off the ground based on their ability that's another one but just be aware and then also pre participation screenings are gonna be optimal because we don't know what they're coming in with in condition wise because sometimes you may not you can't see osteoporosis you can't see arthritis so we just have to be aware to get as much information as possible so again overhead squat depth like the overweight and obese is gonna be optimal try to figure out if their single leg squat is necessary and then again more comfortability for pushing and pulling assessments now prenatal we're talking about pregnant women be again be very aware of what you're getting yourself into with this again movement patterns are gonna be very different for them because they're now how they have a belly so that's gonna be a little bit different for them that's a modification that you're gonna be aware of so again don't take their that they can't do something just because they're pregnant but understand that you know we want to make it more comfortable for them more so than anything else with the assessments up and down off the ground is not gonna be the best choice so we're gonna avoid doing a lot of that and then again depending upon how far along they are this might be something where it's you know if they're in the second and third trimester we're not going prone or supine we're not going prone on the back supine on the belly to compromise their pregnancy so again overhead squat check the depth they might not be able to achieve it especially if they're later on in their pregnancy I would you know they'd also do but I would recommend it from a professional experience don't do the single leg squat because their center of gravity and center of mass is different and then again pushing and pulling is gonna be based on what their comfort level is okay so again all these assessments are gonna just keep getting you know your people better and they're gonna you know as they go through their programming and it's just the next time you do it there when they start seeing their results it makes them happier and wants them to you know then they want to stay and they want to keep getting better so the more options you give people the better is in terms of yeah the scores may not be great initially but the more you work with them and they start seeing wow I'm doing very well and that's why you know always looking at the scale is not the most important thing it's like huh I you know and in two months just say eight weeks you you went up ten ten reps on your push-up assessment that's a big achievement so you know again reassess reassess reassess so you can give new new new and make things less stale okay so again our assessments are meant for getting info whether it's generic information or performance information all of this builds that you know takes all those puzzle pieces and puts them into one beautiful picture and from there we can stay you know start thinking about that next step which is going to be what are the phases that we want to pay attention to for our our exercise and how can we make the best exercise plan possible so everything moving forward from here is going to be the sections of the actual workout plan that we want to focus in on all right so our chapter 13 we'll start with the ending talking about integrated training and then we'll go from there so again thank you and let's continue to move on to our next one
