Adventure Sports

2.1 Core concepts

• Adventure sports are extraordinary activities performed by individuals in search of excitement, extra enthusiasm and the desire to explore nature; they are classified as (1) Adventure water sports, (2) Adventure land sports, and (3) Adventure air sports (NCERT §Intro, p. 328).
• Examples include rafting, surfing (water); mountaineering, trekking (land); paragliding, jumping (air); camping was already discussed in Class IX (NCERT §Intro, p. 328).
• Paragliding is the recreational and competitive adventure sport of flying paragliders; it is engine-less / motor-free and demands courage and decisiveness (NCERT §Paragliding, p. 329).
• Historical development: Domina C. Jalbert invented advanced governable gliding parachutes with multi-cells and lateral-glide controls in 1954; Walter Neumark predicted (in Flight magazine) launching by running off a cliff or slope; French engineer Pierre Lemoigne produced improved parachute designs leading to the Para-commander; David Barish developed the 'sail wing' in 1965 for slope-soaring at ski resorts; in 1985 Canadian Patrick Gilligan and Swiss Bertrand Dubois wrote 'The Paragliding Manual', officially coining the word 'Paragliding' (NCERT §Historical Development of Paragliding, p. 329).
• Classification of paragliding: (1) Light-weight gliding, (2) Free flying glider, (3) Foot-launched glider — like an aircraft with no rigid primary structure (NCERT §Classification of Paragliding, p. 329).
• Sitting position: the pilot sits in a harness suspended below a fabric wing of interconnected baffled cells; wing shape is maintained by suspension lines; valid gliding flights are normally 1–2 hours covering tens of km (NCERT §Sitting Position, p. 329).
• The first official Paragliding World Championship was held in Austria in 1989 (NCERT §First World Championship 1989, p. 329).
• Strength of structure: lines are made of spectra; a single 0.66 mm line can have a breaking strength of 56 kg; wings are 20–35 sq m, span 8–12 m, weigh 3–7 kg; combined gear weighs 12–22 kg (NCERT §Strength of Paraglider Structure, p. 330).
• Speed of paragliders: typically 20–75 km/h (12–47 mph) (NCERT §Speed of Paragliders, p. 330).
• For storage the wing is folded into a stuff-sack inside a rucksack along with the harness (NCERT §Carrying Capacity and Storage, p. 330).
• Instruments: (1) Variometer — helps the pilot find and stay in the 'core' of a thermal, indicates climb/sink rate via beeps/drone and shows altitude; (2) Radio — used in training, communication and rare ATC contact; (3) GPS — necessary in competitions, analyses flight, determines drift, avoids restricted airspace and aids retrieval after landing (NCERT §Instruments, pp. 330–331).
• Flying techniques: launching/landing always done into the wind; Forward launch in low winds (wing inflates as pilot runs forward); Reverse launch in higher winds (pilot faces the wing, then turns around) — has advantages over forward launch (NCERT §Flying Techniques, p. 331).
• Landing: pilots commonly lose height by flying a figure of 8 over the landing zone, then line up into the wind and 'stall' about a metre above ground (NCERT §Landing, p. 331).
• Control: through speed bar mechanism — brakes and accelerator; brakes adjust the glider's speed (NCERT §Control through Speed Bar Mechanism, p. 331).
• Types of competitions: (1) Cross-country flying — classical form, held at club to international levels; (2) Aerobatic — manoeuvres, individual or synchronous pairs; (3) Bivouac flying — a fixed route to be flown/hiked, often over several days (NCERT §Types of Competitions, pp. 331–332).
• Sky parachutes resemble paragliders but differ: in sky-diving the parachute is only a tool for safe return, while paragliders allow longer flights using thermals (NCERT p. 332).
• Surfing: act of riding a wave, with or without a board, regardless of stance; inducted into the Olympics from 2020; a surface water sport where the rider (surfer) rides the forward/deep face of a moving wave (NCERT §Surfing, p. 332).
• History: surfing was central to ancient Polynesian culture for centuries; first observed by British explorers at Tahiti in 1767; George Freeth (1883–1919) is regarded as the 'Father of Modern Surfing' (NCERT §Historical Development of Surfing, p. 332).
• Governing body: International Surfing Association; professional contests began in 1975, when Margo Oberg became the first female professional surfer (NCERT §Governing Body, p. 333).
• Types of surfing: (1) Stand-up Surfing — riding standing on a surfboard, long and short board variants; (2) Body Surfing / Body Boarding — on a body board, lying on belly or drop knee; considered the purest form because no board is used; (3) Surf Matting — on inflatable mats using foils; (4) Tow-surfing — associated with big-wave surfing, a motorised watercraft tows the surfer into the wave (NCERT §Types of Surfing, p. 333).
• Surfboard types: a long board (10 feet) has more friction and is slower — good for beginners needing balance; a smaller (6 feet) board offers control/manoeuvrability — for experienced surfers (NCERT §Types of Surfboard, p. 334).
• Dangers: Seabed — tossed surfers can collide violently with a shallow sea bed, especially at reef/beach breaks during low tide; Rip currents — channels of water flowing away from shore, sometimes 40–50 feet wide, exited by paddling parallel to the shore (NCERT §Dangers during Surfing, p. 334).
• Surfing-related sports: paddle boarding and sea kayaking (no waves needed); kite surfing and wind-surfing (wind-powered); V-drive boat wave surfing — riding the wave of a boat (NCERT §Surfing related Sports, p. 334).
• Safety and security measures (10 points): certification of paraglider, carrying safety instruments (variometer, GPS, radio), wearing helmet/knee/chest guards, no gliding without licensed personnel, recognising wave currents, recognising the deep face of a wave, practising in artificial waves first, regular inspection of brakes and lining, enough practice before long routes, and maintaining physical and mental fitness as the key decision-making factor (NCERT §Safety and Security in Paragliding and Surfing, pp. 334–335).

2.2 Definitions to memorise

2.3 Diagrams / processes to remember

• Fig. 11.1 Paragliding (p. 328) — multiple paragliders soaring above mountains, illustrating the air-sport nature.
• Fig. 11.2 Surfing-1 (p. 332) — surfer riding a wave on a surfboard (stand-up).
• Fig. 11.3 Surfing-2 (p. 333) — surfer on a board mid-ride; illustrates stand-up surfing posture.
• Process: Forward launch → flight → figure-of-8 to lose height → stall ~1 m above ground (landing) (pp. 331).
• Numerical facts to memorise: paraglider speed 20–75 km/h; wing area 20–35 sq m; span 8–12 m; wing weight 3–7 kg; total gear 12–22 kg; line breaking strength 56 kg for 0.66 mm; surfboard sizes 10 ft (long) vs 6 ft (short); rip-current width up to 40–50 feet (pp. 330, 334).

2.4 Common confusions / NTA trap points

• Confusing 1954 (Jalbert invention), 1965 (Barish sail wing), 1985 (term 'Paragliding' coined) and 1989 (First World Championship, Austria) — NTA loves swapping these dates.
• Forward vs reverse launch — forward = LOW winds; reverse = HIGH winds. Distractors flip this.
• Body surfing is the purest form (no board), NOT stand-up surfing.
• Surfing inducted in Olympics from 2020, not 2016 or 2024.
• Margo Oberg (1975) — first female professional surfer; George Freeth — Father of Modern Surfing. These two names are often swapped.
• Exit a rip current by paddling parallel to the shore, not by swimming straight back to shore.
• Variometer measures climb/sink rate and altitude, not speed (speed bar controls speed).
• 10 ft surfboard = long, slow, more friction → beginners; 6 ft = short, manoeuvrable → experienced surfers. NTA loves to invert.
• Cross-country, Aerobatic, Bivouac are the three paragliding competition types — "tow flying" is NOT one (tow-surfing exists in surfing, not paragliding).
• Paraglider speed = 20–75 km/h; wing area 20–35 sq m; span 8–12 m; wing weight 3–7 kg; total gear 12–22 kg. Numeric blocks are CUET goldmines.
• Spectra lines: 0.66 mm = 56 kg breaking strength.
• Surfing was first observed by British explorers at Tahiti 1767 — not Hawaii or Australia.
• Polynesian culture is the ancient root of surfing.
• Landing technique = fly a figure of 8 to lose height → stall ~1 m above ground.

2.5 Key concepts table — adventure-sport classifications, dates, specifications

2.6 Extended discussion — air sport mechanics, water sport heritage and shared safety logic

The structural payoff is the tripartite classification — water / land / air — and the in-depth treatment of one representative from the air category (paragliding) and one from the water category (surfing). Land sports are surveyed only briefly (mountaineering, trekking, camping already covered in Class IX).

Paragliding is presented as the apex air adventure sport because it is engine-less, completely human-launched, and capable of multi-hour cross-country flights using thermals. The historical chain — Jalbert 1954 (governable parachute) → Neumark (predicted cliff/slope launches) → Lemoigne (Para-commander) → Barish 1965 (sail wing for slope soaring) → Gilligan + Dubois 1985 (Paragliding Manual) → Austria 1989 (First World Championship) — is the densest date cluster. The three competition types (Cross-country, Aerobatic, Bivouac) map onto distance, skill and endurance respectively. The instrument trio (variometer, radio, GPS) is a high-yield match-the-following block, with variometer's thermal-core function the single most testable detail. Launch technique (forward = low wind, reverse = high wind) and landing technique (figure of 8 → stall ~1 m above ground) are operational details that CUET frequently weaves into assertion-reason items. The numeric block — 20–75 km/h speed, 20–35 sq m wing area, 8–12 m span, 3–7 kg wing, 12–22 kg total gear, 56 kg line breaking strength — gives examiners ample raw material for direct-recall MCQs.

Surfing is presented as the apex water adventure sport because it requires no propulsion (the wave is the engine) and is now an Olympic sport (inducted from 2020). The history runs from ancient Polynesian roots → first European observation at Tahiti in 1767 → George Freeth (1883–1919) as Father of Modern Surfing → International Surfing Association as global governing body → first female professional surfer Margo Oberg in 1975. The classification cluster — stand-up surfing (long 10 ft board for beginners, short 6 ft board for experts), body surfing (no board, purest form), surf matting (inflatable foils), tow-surfing (big-wave, motor-towed) — is a near-guaranteed CUET match-the-following. The two principal dangers (seabed at reef/beach breaks during low tide; rip currents 40–50 ft wide) are paired with their counter-measures (avoid shallow breaks; paddle parallel to shore). The set of surfing-related sports (paddle boarding, sea kayaking, kite-surfing, wind-surfing, V-drive boat wave surfing) extends the topic's testable surface area.

A 10-point safety protocol shared by paragliding and surfing completes the topic: paraglider certification; carrying safety instruments (variometer + GPS + radio); helmet, knee and chest guards; no gliding without licensed personnel; recognising wave currents; recognising the deep face of a wave; practising in artificial waves first; regular inspection of brakes and lining; sufficient practice before long routes; and the meta-principle that "physical and mental fitness is the key decision-making factor". This protocol commonly appears as a multi-statement "select the correct safety measures" CUET stem. The overall takeaway for CUET preparation is to lock the date cluster, the instrument trio, the launch-technique dichotomy, the surfing classification, the rip-current rule and the 10-point safety list — six chunks that together cover virtually every question this chapter has produced in 2023–25.
