The 18.3 Strain: How to Read Your Body's Dashboard
2 Aug 2026 · the court report
Some weeks shout. This one whispered. Fourteen sessions, over twenty-two hours on court, a strength block squeezed into thirty-five minutes, and one number that tells the whole story: 18.3. That's the biggest strain Naads logged this week. Not a scoreline. Not a ranking point. Just a number that, if you know how to read it, says more than any result ever could.
Strain: The Load You Actually Felt
Training load isn't just minutes on court. It's the combination of volume and intensity your body absorbs. Coaches and sports scientists use a simple metric called "acute load" — how much work you've done recently — and "chronic load" — your baseline over several weeks. The ratio between them is your training-strain score. A score around 18 is not high by pro standards (they often hit 25–30 during peak weeks), but for a junior player it's a meaningful spike.
What does an 18.3 spike feel like? Heavy legs the morning after. A slower first step in warm-up. That weird ache in your hitting shoulder that isn't sharp, just present. It's your body saying, "I've noticed." The clever part is not to ignore it — and not to panic either.
Naads' week shows a smart pattern: 14 sessions, but only 35 minutes of dedicated strength work. That's the classic junior mistake — tennis, tennis, tennis, and almost no physical preparation. The 64 minutes of "other activity" (stretching, mobility, maybe a light bike) helped balance it, but the biggest strain is still tennis-heavy. That's normal for a county No. 1, but it's worth remembering: strain from tennis alone asks a lot of your tendons and joints.
The Post-Training Potato
Here's the part most players get wrong. The diary entry for this week is titled "Post-Training Potato." Now, what does that mean? It could be a meal, a mood, a way of flopping onto the sofa. But whatever it is, it's a perfect image for recovery — the least glamorous, most important part of training.
After a hard session, your body is depleted. Glycogen stores are low, muscle fibres are micro-damaged, and your nervous system is tired. The "potato" phase is when you refuel: carbs for energy, protein for repair, and water to replace what you sweated out. Many juniors skip this — they train, then sit in the car, then do homework, then eat a late dinner. That's like planting a seed and forgetting to water it.
The 35 minutes of strength work in this week's schedule is actually a smart investment, because strength training protects joints and tendons — the things that usually break down from tennis alone. And the 64 minutes of other activity? That's your active recovery: foam rolling, light stretching, maybe a walk. Not heroic, but essential.
Why 18.3 Is a Good Number
Let's put 18.3 in context. For a junior player, a strain score between 15 and 20 is generally a productive zone — enough overload to trigger adaptation, but not so much that you're digging a hole. If it creeps above 25 for several days in a row, you're flirting with overtraining. If it drops below 10, you're probably not training hard enough to improve.
The trick is consistency. One big week does little. Many steady weeks — each with a manageable spike — build the chronic load that makes you fitter, faster, and more resilient. Naads' 14 sessions might look impressive on paper, but the real victory is that the biggest strain stayed at 18.3, not 30. That's discipline disguised as a diary note.
Why It Still Matters
You might not track strain numbers — and that's fine, you don't need an app to know how you feel. But the principle holds: train hard, then recover harder. If you have a heavy week, plan a lighter one. If your shoulder aches, do more mobility. If you're tired, sleep an extra hour.

That's not laziness. That's the smartest part of the training week.
Take It to Court
1. Log your own strain — not exact numbers, but a simple 1–10 honesty rating after each session. If you're at 8 or 9 for three days straight, schedule a lighter day. 2. Protect your recovery — treat the post-training meal like part of the workout. Carbs and protein within 30–60 minutes, then water. The potato can wait, but not too long. 3. Balance tennis with other work — if all your training is tennis, your body will eventually push back. Add 10 minutes of strength or mobility per day; it adds up faster than you think.
