To solve the problem, we need to explain the concept of circuit training and how a coach can design a session using 6 stations for improving the fitness of new trainees.
1. Understanding Circuit Training:
Circuit training is a form of body conditioning or resistance training that uses high-intensity aerobics. It targets strength building and muscular endurance. The format involves a set of different exercises (stations) that are performed in a sequence with minimal rest in between. After completing all the stations (a full circuit), the trainee may rest and then repeat the circuit.
Each station focuses on a different part of the body or a specific component of fitness such as strength, flexibility, endurance, agility, or coordination.
2. Key Features of Circuit Training:
- Involves multiple stations (usually 6–12)
- Each station focuses on a specific exercise
- Exercises can be time-based (e.g., 30 seconds) or repetition-based (e.g., 15 reps)
- Minimal rest between stations
- Can be customized for all fitness levels
3. Planning a Circuit Training Session with 6 Stations:
A coach planning a circuit training session for new trainees should focus on basic movements that cover major muscle groups and energy systems, ensuring variety, safety, and gradual progression.
Example Circuit Plan:
The session starts with a 5–10 minute warm-up (light jogging, stretching).
4. Implementation:
- Each participant starts at a different station.
- After completing the exercise, they move clockwise to the next station.
- Complete 2–3 full rounds (circuits) depending on the fitness level.
- Rest: 30 seconds between stations and 1–2 minutes between rounds.
- End with cool-down stretches.
Final Answer:
Circuit training is a structured method of training involving a series of exercises performed in rotation with minimal rest. A coach can plan a 6-station circuit targeting different fitness components using beginner-friendly exercises and adjust intensity and duration based on the trainee’s fitness level.
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
