Surface Friction In surfing friction is both added Biomechanics of surfing reduced in order to enhance performance and use of a surfboard. Glossing the base of a surfboard means that water is not trapped in the surfboard and glides along the water smoother in comparison to having a sanded base, which traps water.
Also, you want the centre of mass and base support to be close to achieve a sturdy position when surfing waves. Another important feature of the surfboard is the shape, having a point at the end allows the board to cut through the waves, rather than nose diving forwards.
Therefore, bigger boards are easier to ride. The force of water underneath the board and against the fins, counteracts the force of inertia, this prevents you flying over the board as it surfs along the wave.
This is because different age groups, sizes and skill-levelled people are all able to participate in the sport more conveniently. Reduction of surface friction is needed on the base of a surfboard in order to help the board glide along the water at a faster rate, this is done Biomechanics of surfing using a gloss finish or applying product.
Often beginners will start with a large, long foam board and range to professional surfers who ride thin, short boards — this is due to the change base of support creating or reducing stability.
Boards with single and twin fins allow the force of inertia to affect your movement in turns. In terms of surfing the centre of mass is the mid point of your body and base of support is the area of contact underneath the surfboard.
In relation to the technological developments in surfing, the design of the surfboard has increased surfers ability to balance and remain stable. Factors that affect stability are body mass, friction between the body and the surface or surfaces contacted, base of support and position of the centre of gravity.
Therefor surfboards have been created at different length to create a wider range of activity available — a shorter board means more technique and use of skills. This was done through creating friction on the top of the surfboard. A noticeable difference in the surfing industry is the size of a surfboard.
The addition of variety of surfboard shapes and sizes has also increased the love and popularity of this sport around the world.
Having more control of your body and the board can also help to maneuver on the waves. This is to generate less friction between the water and board allowing more maneuverability. In relation to surfing, the force of the water pushing against the bottom of the board as you turn.
Friction To increase stability of the body, it is necessary to increase friction between the body and surface it is in contact with. Stunts introduced and created due to additional manoeuvreablility include: For example, to enact a sharp turn, a surfer moves towards the tail of the board in order to lift the nose whereas if the surfer moves the middle of the board, they will be able to move faster along the wave and across the water; both of the these processes are using the involvement and manipulation of drag forces and friction between the water and the surfboard.
The development of wax used in surfing has created greater friction, therefore greater stability for the surfer. In surfing, this is achieved by waxing their board and therefore increases stability.
Inertia The biomechanics law of inertia is, an object will remain in a state of rest or constant motion unless acted upon by an external force. However it is important to reduce friction on the bottom of the board.Surfing is a surface water sport in which the wave rider, referred to as a "surfer", rides on the forward face of a wave, which is most often carrying the surfer towards shore.
Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or in rivers in the form of a standing wave or tidal bore.
However, modern day Surfing can. May 28, · Balance + Stability Balance in involves the centre of mass and base of support. In terms of surfing the centre of mass is the mid point of your body and base of support is the area of contact underneath the surfboard.
Usually, the bigger or wider your base of support is the more stable you. Basic Concepts Sources of Drag in Surfing 1. Skin Friction Drag – collision of board with water molecules (boundary layer) 2.

Often beginners will start with a large, long foam board and range to professional surfers who ride thin, short boards – this is due to the change base of support creating or reducing stability. The problem with my surfing is my paddling technique. Understanding the fundamental relationships in mechanics, helps form a foundation for the analysis of human movement in surfing.
