Padh le Bhai 😂
Very helpful
ONE DAY BEFORE BALA LIKE KARO 😅😂
Additional topic ka dar lg rha hai ve😢
Paper ke din vale like kro💀
Toda padh leta hu ab 😂😂😂
Aaj exam h 😢😢😢
Mera bhi yhi haal h😅😅
Abhi tk aadha hi kiya h aadhe ghante me... 😂
Paper wali subhaa pdhne wale 😂
Same 😂
Same😂😂
शिक्षा से बड़ा कोई ज्ञान नहीं,,, गुरु से आशीर्वाद मिले इससे बड़ा कोई सम्मान नहीं 😇🥰🙏🥲📚📚💯💯

Thank you mam
Notes of chapter 7 is not in drive
Notes nhi h
Mam chapter 7 upload ni kiya apne drive pr pls upload ker dijiye Perso exam hai 😢
Kon abhi tak yhi tak padh paya 😂
Abhi toh Puri raat padi hai 😅
padh nhi paya ❌❌ padha hi nhi ✅✅
mam didn't cover all the topics
Bhai kon ab start kr rha ped like kro ❤
Ma
😢😢जितना कठिन संघर्ष होगा
जीत भी उतनी ही शानदार होगी😊🎉❤❤
I Love
Physical education op subject ❤❤❤❤aag laga denge 12 March ko 🔥🔥🔥🔥
Mam Mera dost aapko hi dekhta rhta ha padai nhi krta
Usee bol ki Chashma Laga Ke Dekh😂😂
Mam please also make a video on all expected ques and pyqs one shot video.Jaise apne English ki banai thi vo bhut helpful rahi. Mam please please 🙏 exam se pehle .And mam thankyou so much mam for your hardwork towards us
physiological factors determining strength-
1)size of muscle
2) composition of muscle
white fiber (more strength, more force, larger) red fibre (iska ulta competitively)
3) intensity of nerve impulse
4) body weight
Factors determining speed
1) muscle composition
white fibre (fast)
2) explosive strength-It depends on the size shape and coordination of muscles.explosive strenth dir. prop. to speed
3)flex direct. prop. speed
4) biochemical reserve and metabolic power-
muscle require more energy and high rate of consumption for maximum speed. for this ATP and CP in three muscles should be enough.
Physiological fsctirs for determining flexibility-
1) muscle strength-dir. prop flex
2) joint structure-some joint have greater range of motion,eg-ball and socket joint of shoulder have greatest take off motion
3) age and gender-female More
age inv. prop flex
4)internal env-temp inv. prop flex
Physiological factors determining endurance-
Oxygen uptake-highest rate at which oxygen can be taken up and consumed by the heart per minute
cardiac output-amount of pumped by the heart per min
energy reserve-dir prop
lactic acid tolerance-
muscle composition
Abrasion
Abrasion injuries most commonly occur due to moving,
Didi chapter 6,7,8,10 ke Notes Google drive link main nahi hai please update it..
Yes mam
Pls😊😊
😢
Video bhi nahi hai

Kal kis kis ka exam ho 😂😂
mera😂😂😂
Jo abi pdd rhe ha eak baar apne channel pr jake prso ki short dekho paper leak hogya ha 😂❤
Shi btao bhyiii
Inter nal environment...the internal environment of an athlete ..influence the flexibility...if internal...temperature incere ...flexibility increase.. if the internal temperature decreases flexibility decreases
Ab ni kuch ho skta pura saal to pdha ni 😂😂
Factor of strength
1. Size of muscle
Factors:
Size of the muscles
Muscles composition
Intensity of the nerve system
Body weight
Explosive strength
Flexibility
One day before exams students give attendance here 😂😂
Physiological factors determining endurance :
Oxygen uptake
Cardiac output
Energy reserves
Movement economy
Muscle composition
Physiological factors for determining flexibility :
Muscle strength
Joint structure
Age and gender
Internal environment
Muscle composition...each muscle contain two types of fibres
...fast twitch white fibres
Or slow twitch fibres...
The percentage of fast twitch or low twitch fiber...are genetically determined and cannot be changed through the training...
If the percentage of fast twitch fibres is more they produce large amount of strength
Intensity of nervous impulse ...
The muscles contain...no of motor units ...the total force of the muscle depends in the no of contraction of motor units...
Joint structure..there are several different type of joints in Humana body ...some of the joints have higher range of motion
Ex...ball and socket joint have greatest range of motion ...
Biochemical reserves.. and metabolic power...the muscle require high amount of energy..and tight rate of consumption for maximum speed performed...for ATP nd cp...the store is enough..if the store is less..the working of muscle is stop after a short period of time
I am watching this 5 days before exam😮
I am watching 1 day before exam 😂
Same
Hehe😂
@@iamsteve.06 same same😅😅
Kon aya abhi dekhne 😅😅
Flexibility..is also determine the speed
....in fact flexibility is good it also...maximum range of movement
Effects of exercise on muscular system :
Change in size & shape of muscle
Correct body posture
Food storage increases
Toned muscles
Efficient movement of muscles
Change in connective tissues
Simran di, please make a video specially on lever and its types 😢
Factors affecting strength..
1. Size of muscle
Strength depend on the size of muscle...if the size of muscle is larger it produced more force...size of muscle can be increased by doing various exercises...
Effects of exercise on Cardio Respiratory system :
Decrease in resting heart rate
Increase in size of heart
Stroke volume increases at rest
Increase in cardiac output
Increased blood flow
Decrease in blood pressure
Increase in blood volume

Drive pe saare chapters k notes uploaded hai kya ?? Coz mujhe mil nahi rhe kuch chapters Missing Lgre h
haan kuch missing hai
Whi tohh
sirf 1 h

Baki ke chapter kaha hai
Shuru krdiya bass syllabus sham takk khtm krduga or top krduga exam me 😂
😢😢बिना परिश्रम के ज्ञान नहीं मिलता है
बिना शिक्षा के सम्मान नहीं मिलता है 🎉😊😊
Muja physical bhut tough kyu lgra h 😢
Same 😢
She is teaching so badly
Explosive strength ...it depends on the size .shape of muscle...for very fast moment. Explosive strength is required
Mam u are the one and only reasons to study for me
Size of the muscle
Composition of muscle
Those who r still watching 👀😂??
Factors affecting strength are
1. Size of the muscle
2. Muscle composition
3. Body weight
4. Nervous system
Didi iska pdf nhi hai
Ageing
Aging is the process of becoming older.
Dii is chapter ke notes upload kr dijiye revision Krna tha plzzz😢😢
All the best guyzz❤
SM2❤
😢😢कौन कहता है कि सफलता luck से मिलती है
😇😇 इरादे मजबूत होनी चाहिए मंज़िल भी झुका करती है😍😇📚🥲🥲🥲
factors- strength of muscle,
body weight, intensity of nerves
Body weight
the person who are having fast twitch fibre that has been also a more strength
Physiological factors determining strength
Size of the muscle: the strength of an individual depends on the size of the muscle
Itna yad karna hai maine isliye To Nahin Li thi pcm 😂😂😂
Flexibility elasticity, extendibility muscle ,joint type, homothermic temperature
Muscle , tendon , ligament
Agonist muscle contract perform action
Antagonist oppose primer move relax,lengthen allow agonist move
Synergist either contract,relax modify action agonist
Factor determining strength
Size of muscle
Muscles composition
Intensityof tha nerve
Muscle composition fast twitch fibre
Endurance maximal oxygen consumption V02, ventilation capacity
Speed motor neuron stimulation energy demand ATP cp system
Size of the muscle
Muscle composition
Factors affecting strength

2- compo
Mam you are wrong here that you are saying who have big bicep and tricep aur other body part they have much endurance i agree but who is on cut also have big muscle but he or she feel not good or have no power you should study more of body building and nutrition facts ! Sorry mam !
And which picture you are showing of that gay should not have much endurance and power !
Physiological factors for determining strength
Size of The muscle :- The strength of an individual depends on the size of muscle. As larger and bigger muscle produce more force with The help pf different methods of strength trainning the size of muscle can be increased
