Chain Reaction Biomechanics

In my last blog I gave an account of my recent allergic reaction to an antibiotic for an  apparent tooth infection and described how it affected the rest of my body. After 5 days without being able to swallow water or food, a timely intervention in A+E, which put me on an IV drip with … Read more …

This post will be a very personal story about my experience in the last few weeks during which I had a severe allergic reaction to an antibiotic prescribed for a recurring tooth infection. I am not medically qualified to make the connections in my recovery but I was there, I experienced them and witnessed others … Read more …

The upper body motion in the serve and overheads. Shoulder injuries: A common complaint for tennis players Should, and do these statistics worry you? Shoulder pain is extremely common in tennis players. Studies suggest up to 25% of high-level players aged 12 to 19 and up to 50% of middle-aged players have shoulder pain. The … Read more …

The source of power for human movement in a chain reaction, in all three planes of motion, in upright function. I’ve just watched an insight into the source of power in the serve, from a provider on YouTube. I was impressed with his subscriber number at 28,000 and the 540 likes he got for his … Read more …

In this final phase, the reload, I will cover the motions of the landing leg as it meets the ground and how it loads and transforms into an explode force in another direction. It is the third major transformational zone as Justine rebalances and resets herself for the next move. It leads into smaller  interim … Read more …

The final stage of the explode phase is 2 b), the drive up to and through contact of the racket arm. I covered the whole upper body movement in the my previous vlog which illustrated the elastic recoil motion you can see in Transformational zone 2. In this vlog I want to take a close … Read more …

The second major transformational zone in the chain, is the load explode in the shoulders from the hip drive. Harnessing ground reaction force and momentum in the drive up, the hips initially turn the shoulders back and down  creating a front to back slope  before the shoulders reverse. This transformational movement is prior to and … Read more …

In this vlog , I want to draw your attention to the phase 2.a)  movements both in terms of all three planes of motion and the physical forces acting on the body. As the loading  transforms into exploding upwards, I want to highlight the motions in all three planes and describe the physical forces being … Read more …

There are many uses of this word in our language. In this context  it is the zone where loading the body in one direction  transforms into the explode of that force in another direction of movement. It can be in one but more usually is in all three planes of motion in the muscles and … Read more …

The serve, both first and second, is the first stroke in a tennis point, first chronologically but also first in terms of importance, as without it the point cannot progress.
