Kapalbhati Pranayama involves forceful exhalations and passive inhalations. This rapid breathing technique helps in increasing the metabolic rate, which aids in burning calories and reducing fat. It tones abdominal muscles and improves digestion, both crucial for weight management. Anulom Vilom, while beneficial for overall health, focuses on balancing the flow of energy, and Suryabhedan Pranayama primarily energizes the body. Sheetali Pranayama is a cooling breath that may not directly contribute to weight loss. Quick Tip: Remember the specific benefits of different Pranayama techniques. Kapalbhati is your go-to for weight management due to its effect on metabolism and digestion.

The International Paralympic Committee (IPC) was founded in 1989. The IPC is the global governing body of the Paralympic Movement. It organizes the Paralympic Games and acts as the International Federation for nine sports, supervising and coordinating World Championships and other competitions. It's important to distinguish the IPC's founding from other disability sports organizations. Quick Tip: Remembering key dates in sports history, such as the formation of governing bodies, can be helpful for multiple-choice questions.

Food intolerance occurs when a person has difficulty digesting a particular food. This can be due to various factors: lack of a specific enzyme necessary for breaking down a food component (like lactase for lactose), a reaction to chemicals or toxins present in the food, or sensitivity to certain food proteins like gluten. Roughage, which is dietary fiber, is essential for healthy digestion and isn't a cause of food intolerance itself. In fact, lack of roughage can cause digestive problems. Quick Tip: Understand the difference between food intolerance (digestive difficulty) and food allergy (immune response). Food intolerance is generally linked to missing enzymes or reactions to specific components.

BMR represents the minimum energy required to keep the body functioning at rest, including vital functions like breathing, circulation, and cell production. Even when not actively engaged in physical activity, the body needs energy to sustain these processes. Therefore, both the assertion and the reason are true, and the reason correctly explains why BMR is essential even without external work. Quick Tip: BMR is the baseline energy expenditure. It's the minimum energy your body needs just to exist, even when asleep!

Planning (I) involves charting a future course of action (2). Controlling

(II) focuses on measuring performance against standards and identifying discrepancies (4). Directing

(III) involves guiding and motivating people towards goals (1).
Staffing (IV) ensures appropriate talent allocation to specific tasks (3).
Quick Tip: Relate each management function to its core purpose: Planning sets the direction, Controlling monitors progress, Directing guides actions, and Staffing provides resources.

Step 1: Determine the correctness of Assertion (A): A normal standing posture typically has a small gap between the knees, not the ankles, with feet approximately shoulder-width apart for stability. The posture described where the knees touch while the ankles are apart (Genu Valgum) isn't normal, but a misalignment.

Step 2: Analyze the correctness of Reason (R): Reason (R) explains Genu Valgum, which is a condition characterized by the knees angling inward and touching. The conditions described like injury, rickets, Vitamin D deficiency, obesity, or arthritis correctly lists reasons that can cause this condition to develop.

Step 3: Determine if Reason (R) is the correct explanation: While the assertion that the posture described is considered normal is incorrect, Genu Valgum can be present where the knees touch together and the ankles are somewhat apart, making the condition that the Reason is describing directly related to the state in the assertion. Therefore the two have a direct relation.
Quick Tip: Carefully analyze the assertion to see if it accurately reflects the typical case. A thorough understanding of what’s typical and what’s a condition is essential. Visualize correct posture. Knees slightly apart, feet shoulder-width apart, provides stability and balance.

Slow-twitch muscle fibers are designed for endurance activities. They contract slowly and resist fatigue, making them ideal for prolonged exercise like long-distance running or cycling. Fast-twitch fibers, while powerful for short bursts, fatigue quickly and are better suited for activities requiring speed and strength, such as sprinting or weightlifting. Quick Tip: Associate slow-twitch with “slow and steady" endurance, and fast-twitch with “fast and furious" short-duration power.

Equilibrium, or balance, is enhanced by a lower center of gravity and a wider base of support. A higher center of gravity makes an object more likely to tip over. Greater weight can contribute to stability if the center of gravity remains low. Imagine a pyramid: wide base, low center = stable; tall, narrow = unstable. Quick Tip: Think “low and wide" for stability. A wrestler lowers their center of gravity and widens their stance for better balance.

Introverts tend to be more focused on their inner thoughts and feelings. While not necessarily “selfish" they gain energy from solitude and may be less inclined to readily socialize with new people. Extroverts, conversely, are often expressive and thrive in social interactions. Self-centeredness, a focus on oneself, is better aligned with introversion. Quick Tip: Introverts recharge in solitude; extroverts recharge in social settings. Self-centeredness implies a focus inward, a trait more common in introverts.

A volleyball smash requires a rapid, powerful movement. This is a demonstration of explosive strength, which combines speed and strength. Static strength involves holding a position without movement, maximum strength is the peak force exerted, and strength endurance is the ability to sustain repeated contractions. Quick Tip: Explosive strength is “quick power" like a jump or a throw. Other strength types involve different speeds and durations of force application.

Intramural competitions are held within a school or organization. The primary goal is participation, recreation, and promoting a healthy lifestyle amongst students or members. These are not career-oriented or designed for elite-level performance (like interscholastic or international competitions). The focus is on fun, fitness, and building social connections within the community. Quick Tip: “Intra" means within. Intramurals are for participation and fun inside a group. “Inter" means between; interscholastic competitions are between schools.

The WHO recommends that children aged 3-4 years should have at least 180 minutes (3 hours) of physical activity of any intensity spread throughout the day, including active play, structured exercise, and travel to and from places. This age group also requires 10-13 hours of good quality sleep, which is critical for growth, development, and cognitive function. The WHO provides different recommendations for various age groups based on their developmental needs. Quick Tip: Physical activity and adequate sleep are vital for children's health. Remember the 3-hour activity guideline for preschoolers.

The image depicts Shalabhasana (Locust Pose). This pose strengthens the back muscles, improves posture, and stimulates abdominal organs. It is distinct from Bhujangasana (Cobra Pose), Katichakrasana (Standing Spinal Twist), and Pawanmuktasana (Wind-Relieving Pose). Quick Tip: Shalabhasana resembles a locust with the body lifted off the ground. Note the distinct arm and leg positioning in each asana.

Shavasana, also known as Corpse Pose, is specifically designed for relaxation. It involves lying flat on the back with arms and legs slightly spread, promoting complete physical and mental stillness. This allows the body to release tension and deeply rest, effectively reducing fatigue. Other asanas like Chakrasana (Wheel Pose), Makarasana (Crocodile Pose), and Uttanpadasana (Raised Legs Pose) have different focuses related to strength, flexibility, or digestion, and are not primarily intended for relaxation. Quick Tip: Shavasana is unique in its focus on complete stillness and rest. It's the ultimate “letting go" pose in yoga.

The International Committee of Sports for the Deaf (ICSD) is the main governing body responsible for organizing the Deaflympics, also known as the Deaflympic Games. The ICSD is recognized by the International Olympic Committee (IOC) and promotes sports for deaf athletes at an international level. While National Sports Federations may play a role in selecting and training athletes, they are not the overall governing body for the Deaflympics. The International Co-ordinating Committee Sports for Disabled (ICC) is a broader organization addressing disability sports in general, and the World Deaf Champions Committee is not the official name of the governing body. Quick Tip: The ICSD is dedicated specifically to deaf sports, similar to how the IOC governs the Olympics.

A BMI between 18.5 and 24.9 is generally considered healthy. Below 18.5 is underweight, 25.0-29.9 is overweight, and 30.0 and above is obese. BMI provides a quick assessment of weight status relative to height. Quick Tip: Remember the healthy BMI range: 18.5 to 24.9. BMI provides a general indicator of health risks associated with weight.

In the partial curl-up test, two parallel lines are marked 6 inches apart. This distance standardizes the movement and ensures consistency in measuring abdominal strength and endurance. The individual performs curl-ups, reaching forward to touch the second line. Quick Tip: The 6-inch gap in the partial curl-up test is key to accurate measurement. It regulates the range of motion for each curl-up.

Goal setting is a cognitive strategy involving conscious thought processes. It requires individuals to plan, strategize, and mentally prepare to achieve desired outcomes. This mental aspect distinguishes it from pedagogical (teaching), social (interaction-based), or facilitation (support-oriented) approaches. Quick Tip: Goal setting is a “mind game". It's about mental focus, planning, and visualizing success.

The Chair Sit and Reach test assesses lower body flexibility, particularly hamstring and lower back flexibility. It does not directly measure physical mobility (overall movement capacity), upper body flexibility, or upper body strength. Quick Tip: The Chair Sit and Reach test focuses on flexibility in the lower body, essential for everyday activities like bending and reaching.

The Arm-Curl Test specifically measures upper body strength in seniors. It involves performing bicep curls with a light weight (e.g., 5 pounds for women, 8 pounds for men) for a set number of repetitions (e.g., 30 seconds). The Chair Stand Test assesses lower body strength and endurance, the Back Scratch Test measures upper body flexibility, and the Chair Sit and Reach Test evaluates lower body flexibility. Quick Tip: The Arm-Curl Test is a safe and effective way to assess upper body strength, important for maintaining independence and functional capacity in older adults.

A second-class lever is characterized by the load (resistance) being positioned between the fulcrum (pivot point) and the effort (force). This arrangement magnifies the force applied, making it easier to move heavy loads with less effort. The mechanical advantage of a second-class lever is always greater than 1.

Example in Sports: Calf raises. When you stand on your toes, the ball of your foot acts as the fulcrum. The weight of your body acts as the load, concentrated in the middle of your foot. The effort is applied by your calf muscles, pulling upwards on the heel bone. This lever system allows your calf muscles to lift your entire body weight with relative ease. Quick Tip: Remember FLE (Fulcrum-Load-Effort) for second-class levers. Imagine a wheelbarrow: the wheel is the fulcrum, the load is in the center, and you lift the handles (effort).

The Johnson-Metheny Test of Motor Educability assesses an individual's gross motor skills and their ability to learn and perform new motor tasks. The four test items are:


1. Front Roll: Assesses coordination, body control, and spatial awareness.

2. Back Roll: Similar to the front roll, evaluating coordination and body awareness in a different plane of movement.

3. Jumping Half-Turns: Requires coordination, balance, and the ability to change direction quickly.

4. Jumping Full-Turns: A more complex movement, demanding greater control, balance, and coordination.
Quick Tip: The Johnson-Metheny test helps identify areas of strength and weakness in gross motor abilities. These fundamental skills are building blocks for more specialized sports movements.

Menarche is the first occurrence of menstruation in females, marking the beginning of their reproductive life. It is a significant event during puberty, typically occurring between the ages of 8 and 15.


Physiological Significance: Menarche signals the maturation of the reproductive system, indicating that the ovaries have begun releasing eggs and the body is capable of pregnancy.

Hormonal Changes: It is triggered by a complex interplay of hormones, including estrogen and progesterone.

Psychological Impact: Menarche can have significant psychological impact on girls, as it signifies a transition into womanhood and can be associated with various emotions, anxieties, and cultural beliefs.

Factors Affecting Age of Onset: Several factors can influence the age of menarche, including genetics, nutrition, body weight, and overall health.
Quick Tip: Menarche is a normal biological process. Open communication and education can help girls understand and cope with the physical and emotional changes associated with puberty.

Several asanas can be beneficial for managing asthma by improving breathing capacity, reducing stress, and strengthening respiratory muscles. Here are four examples:


1. Sukhasana (Easy Pose): This simple seated posture promotes relaxation and deep breathing, which can help manage asthma symptoms.

2. Bhujangasana (Cobra Pose): This backbend stretches the chest and opens the airways, improving lung capacity.

3. Matsyasana (Fish Pose): This posture stretches the throat and chest, improving respiratory function. It can be particularly helpful for those with asthma.

4. Ardha Matsyendrasana (Half Spinal Twist): This twisting asana massages the abdominal organs and improves the flexibility of the spine, which can indirectly aid in breathing.

Quick Tip: While these asanas can be helpful, asthma management requires a comprehensive approach, including medical guidance and prescribed medication. Yoga should be seen as a complementary therapy.

Physical activity is crucial for all children, but it holds particular significance for children with special needs (CWSN). Here are two key advantages:

1. Improved Physical Functioning: Physical activity can help CWSN develop and improve their gross and fine motor skills, balance, coordination, and overall physical fitness. This can lead to greater independence in daily activities and improved quality of life. Specific exercises and activities can be adapted to meet individual needs and abilities.


2. Enhanced Social and Emotional Well-being: Participating in physical activities, especially in inclusive settings, can boost self-esteem, reduce anxiety and stress, and foster a sense of belonging. Teamwork and interaction with peers can improve social skills and communication.
Quick Tip: Adapted physical education programs are designed to meet the unique needs of CWSN. Consult with specialists to create individualized activity plans.

Friction, the force resisting relative motion between surfaces, plays a critical role in sports. Here are two types with examples:

1. Static Friction: This is the friction that prevents two surfaces from sliding past each other when they are at rest. In weightlifting, static friction between the lifter's hands and the barbell is essential for gripping and lifting the weight. Similarly, a rock climber relies on static friction between their shoes and the rock face.

2. Sliding Friction: This friction occurs when two surfaces slide against each other. In skiing, sliding friction between the skis and the snow allows controlled descent down a slope. A baseball player sliding into a base experiences sliding friction, which helps slow them down. Quick Tip: Think of static friction as “grip" and sliding friction as “glide". Athletes manipulate friction to their advantage to control movement and enhance performance.

The Harvard Step Test assesses cardiovascular fitness by measuring how quickly the heart rate recovers after exercise.

Formula:

Fitness Index = (Duration of Exercise in Seconds \( \times \) 100) / (5.5 \( \times \) Sum of Pulse Counts in Recovery Periods)

Calculation for Mr. X:

Duration of exercise = 275 seconds

Pulse count 1-1.5 min after exercise = 100 (We assume this is the sum of three 30-second pulse counts, as per standard protocol.)


Fitness Index = (275 \( \times \) 100) / (5.5 \( \times \) 100) = 50 Quick Tip: A higher fitness index indicates better cardiovascular fitness. Regular aerobic exercise can improve your score on this test.

Bhujangasana (Cobra Pose): This asana strengthens back muscles and improves flexibility, potentially easing pain.

Procedure: Lie on your stomach, palms flat beneath your shoulders. Inhale, press into your palms, and lift your chest off the floor, arching your back. Hold, exhale, lower.

Benefits: Strengthens erector spinae (back muscles), increases spinal flexibility, stretches chest and shoulders, may reduce back pain. Quick Tip: Consult a doctor or physical therapist before starting any new exercise program, especially if you have existing back pain. Correct form is crucial to prevent further injury.

The Female Athlete Triad is a serious health condition that can affect female athletes, particularly those involved in sports emphasizing leanness or low body weight. It involves three interconnected components:

1. Low Energy Availability (LEA): This occurs when an athlete's energy intake is insufficient to meet the demands of their training and daily activities. It often stems from disordered eating, restrictive dieting, or an inadequate understanding of nutritional needs.

2. Amenorrhea: LEA can disrupt hormonal balance, leading to irregular or absent menstrual periods (amenorrhea). This can have long-term consequences for bone health and fertility.

3. Osteoporosis: Reduced estrogen levels associated with amenorrhea can lead to decreased bone mineral density and increase the risk of stress fractures and osteoporosis. Quick Tip: Early intervention is key in addressing the Female Athlete Triad. Athletes should prioritize balanced nutrition, consult with sports dieticians, and address any menstrual irregularities with a healthcare professional.

Ageing brings about various physiological changes impacting physical capacity and overall health. Here are three key changes:

1. Decreased Cardiovascular Function: The heart muscle weakens, maximum heart rate declines, and blood vessels lose elasticity. This can lead to reduced aerobic capacity and increased fatigue.

2. Loss of Muscle Mass and Strength (Sarcopenia): Age-related decline in muscle mass can reduce strength and power, impacting mobility and increasing the risk of falls.

3. Decreased Bone Density (Osteoporosis): Bones lose density and become more brittle, making them more susceptible to fractures. This is particularly pronounced in post-menopausal women due to hormonal changes. Quick Tip: Regular exercise, especially strength training and weight-bearing activities, can help mitigate the physiological effects of aging and maintain functional independence.

(a) Solution: Long Jump Quick Tip: Analyze the data carefully. The table clearly shows zero participation of special needs children in the long jump event.

(b) Solution: Inclusion / Adaptive Physical Education
Quick Tip:Inclusion and adaptive physical education aim to provide opportunities for all students to participate and benefit from physical activity.

(c) Solution:1. Modified Equipment: Using lighter balls, larger targets, or adaptive sports equipment can make activities more accessible and enjoyable.
2. Peer Support and Buddies: Pairing students with disabilities with classmates who can provide assistance and encouragement fosters inclusion and positive social interaction.
Quick Tip:Focus on adapting activities to the individual’s abilities rather than limiting participation. Creativity and flexibility are key!

(d) Solution: Special Olympics Motto: “Let me win. But if I cannot win, let me be brave in the attempt.” OR “Joy and Happiness for all the children of the world.”

Paralympics Motto: “Spirit in motion”
Quick Tip:The Special Olympics emphasizes bravery and joy in participation. The Paralympics highlights the indomitable spirit of athletes with disabilities.

Paralympics: The Paralympic Games are a major international multi-sport event involving athletes with a wide range of disabilities, including impaired muscle power, impaired passive range of movement, limb deficiency, leg length difference, short stature, hypertonia, ataxia, athetosis, vision impairment, and intellectual impairment. They are held every two years, alternating between the Summer and Winter Paralympics, and follow immediately after the respective Olympic Games.

Special Olympics: The Special Olympics is a global movement providing year-round sports training and athletic competition in a variety of Olympic-type sports for children and adults with intellectual disabilities. The aim is to promote inclusion, acceptance, and empowerment through sports. The Special Olympics World Games are held every two years, alternating between Summer and Winter Games. Quick Tip: Both the Paralympics and Special Olympics offer incredible opportunities for athletes with disabilities to compete and achieve their full potential. They promote inclusion and celebrate athletic excellence.

(a) Solution: Transverse fracture Quick Tip: A transverse fracture is a break straight across the bone.

(b) Solution: Oblique
Quick Tip:An oblique fracture occurs at an angle across the bone.

(c) Solution: Impacted
Quick Tip:In an impacted fracture, the broken ends of the bone are driven into each other.

(d) Solution: Comminuted
Quick Tip:A comminuted fracture results in multiple bone fragments.

1. Transverse Fracture: The break is in a straight line across the bone.

2. Oblique Fracture: The break is at an angle across the bone.

3. Spiral Fracture: The break spirals around the bone, often caused by a twisting force.

4. Comminuted Fracture: The bone is broken into three or more pieces.

5. Greenstick Fracture: The bone is bent and only partially broken; common in children.

6. Stress Fracture: A small crack in the bone, often caused by repetitive stress or overuse.

7. Compression Fracture: The bone is crushed or collapses, often occurring in the spine.

8. Avulsion Fracture: A fragment of bone is pulled away from the main bone by a tendon or ligament.

(Explain any 4 fractures from the above-mentioned fractures.) Quick Tip: Fractures are classified based on the pattern of the break. Prompt medical attention is crucial for proper diagnosis and treatment.

(a) Solution: 4 Quick Tip:Count the branching levels in the fixture to determine the number of rounds.

(b) Solution: 15
Quick Tip:The team with the bye in the final round plays the fewest matches.

(c) Solution: Number of matches = N – 1, where N = Number of teams
Quick Tip:In a knockout tournament, one team is eliminated after each match, so the number of matches is one less than the total number of teams.

(d) Solution: If the number of participating teams is 16, the answer will be 0 (zero) byes. If the number of participating teams is not a power of 2, byes are given in the first round to ensure a proper progression to the next rounds.
OR
No. of byes = (Next higher Power of 2 – Number of Teams)
Quick Tip:Byes are allocated to balance the fixture when the number of teams is not a power of 2.

Sports Day: Sports days promote health awareness by emphasizing the importance of physical activity and fitness. They provide a platform for participation in various sports and games, encouraging students to adopt a healthy and active lifestyle. Furthermore, sports days foster harmony by bringing students together in a spirit of friendly competition and teamwork. They encourage interaction and collaboration between students of different abilities and backgrounds.

Health Run: Health runs are organized to create awareness about specific health issues and promote the benefits of regular exercise. These events involve people of all ages and abilities, raising community awareness and fostering a sense of collective responsibility towards health and well-being. Health runs also provide an opportunity for people to come together, promoting social interaction and a sense of community. Quick Tip: Sports days and health runs are effective tools for promoting physical activity, creating health awareness, and building a sense of community.

Aggression in Sports: Aggression in sports refers to behavior directed towards another person with the intent to cause harm, either physically or psychologically, outside the rules of the game. It involves hostile or violent actions exceeding the accepted norms of competition.

Types of Aggression:

1. Instrumental Aggression: This type of aggression is used as a means to achieve a specific goal within the game, such as tackling an opponent in football to gain possession of the ball. Although it can involve physical contact, the primary intent is not to inflict harm but rather to achieve a strategic advantage.

2. Hostile Aggression: This involves actions intended primarily to harm or injure another player. It is often driven by anger, frustration, or the desire for revenge and is usually outside the rules of the game. An example would be a player deliberately hitting an opponent out of frustration after a perceived foul. Quick Tip: Instrumental aggression is strategic; hostile aggression is harmful. Recognize the intent behind aggressive actions to differentiate between types.

Balanced Diet: A balanced diet consists of the essential nutrients—carbohydrates, proteins, fats, vitamins, minerals, and water—in the right proportions to meet the body's energy and nutritional needs.

Significance of Pre and Post-Competition Meals:

* Pre-Competition Meal (1-4 hours before): The pre-competition meal aims to maximize energy stores (glycogen) and provide easily digestible fuel. It should be high in carbohydrates, moderate in protein, and low in fat and fiber to avoid digestive discomfort. Examples include pasta, rice, bread, and lean protein.

* Post-Competition Meal (within 2 hours after): This meal aims to replenish glycogen stores, repair muscle damage, and rehydrate the body. It should include carbohydrates, protein, and fluids. Examples include chocolate milk, smoothies, or a meal with lean protein, vegetables, and whole grains. Quick Tip: Fueling your body properly before and after competition can significantly impact performance and recovery. Consult a sports dietician for personalized nutrition plans.

Projectile Trajectory: The path a projectile follows through the air under the influence of gravity and air resistance is called its trajectory. It is usually a parabolic curve.

Factors Affecting Trajectory:


1. Angle of Projection: The angle at which the projectile is released significantly affects its trajectory. A 45-degree angle generally results in the greatest horizontal distance for a given initial velocity.

2. Initial Velocity: The greater the initial speed at which the projectile is launched, the farther it will travel.

3. Gravity: Gravity acts downwards, causing the projectile's vertical velocity to decrease and eventually bringing it back to the ground.

4. Air Resistance: Air resistance opposes the motion of the projectile and can affect both its horizontal and vertical distance. The size, shape, and surface of the projectile, as well as wind conditions, influence air resistance.

5. Spin: Spin can cause a projectile to curve or deviate from its normal parabolic path due to the Magnus effect (the pressure difference created by spin). Quick Tip: Understanding projectile motion is crucial for optimizing performance in many sports like shot put, basketball, baseball, and soccer.

Endurance is the ability of the body to sustain prolonged physical activity without experiencing undue fatigue. It's crucial for success in many sports and essential for overall health.

Types of Endurance based on Duration:

1. Short-Term Endurance (45 seconds to 2 minutes): This type of endurance is utilized in activities requiring high intensity for a relatively short duration. An example would be an 800-meter run in track and field, where the athlete must maintain a fast pace for approximately two minutes. Short-term endurance primarily depends on anaerobic energy systems.

2. Long-Term Endurance (over 11 minutes): This refers to the ability to sustain lower-intensity activity for extended periods. Marathons, triathlons, and long-distance cycling are examples where long-term endurance is crucial. It relies primarily on aerobic energy systems. Quick Tip: Different types of endurance training target different energy systems. Short bursts of high-intensity exercise improve anaerobic capacity, while prolonged, lower-intensity activities boost aerobic endurance.
