# Acute:Chronic Workload Ratio (ACWR) Analyzer MCP for AI Agents AI Agent Connect > Acute:Chronic Workload Ratio (ACWR) Analyzer predicts injury risks by comparing an athlete's recent training volume to their long-term baseline. It helps coaches and sports scientists spot dangerous spikes in intensity before they lead to physical setbacks. By turning raw metrics into actionable risk tiers, you can make better decisions about athlete readiness and training volume. ## Overview - **Category:** sports-science - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_6wJPlJEEtkpKouxdrtkiIYI1VteE0uLwqMkHkJ3C/ai-agent-connect - **Tags:** acwr, injury-prevention, athlete-performance, workload-management, sports-analytics ## Description If you're managing an athlete's training, you know that a sudden spike in intensity is usually where the injury happens. This Connector handles the heavy lifting of sports science by turning raw training data into a clear picture of physical stress. Instead of guessing if a workout was too much, you can ask your agent to look at the relationship between what an athlete did this week versus what they've done over the last month. It identifies specific danger zones, like when a load spikes too fast or when a player isn't doing enough to stay ready. You can actually get specific training prescriptions based on these numbers, making it a lot easier to adjust a schedule on the fly. When you add this to your stack via Vinkius, you're essentially giving your AI the same data a high-end sports science team uses to keep players on the field. It takes the guesswork out of periodization and gives you a clear path forward for every individual in your program. ## Tools ### calculate_acwr_series Calculates a series of ACWR values to show how load ratios change over time. This helps you see the progression of training stress. ### evaluate_risk_tier Places an athlete into a specific risk category like Safe, Warning, or Danger. This makes it easy to prioritize your attention. ### generate_training_prescription Provides actionable coaching advice to adjust training based on detected risks. It gives you a clear plan for what to do next. ### detect_load_trend Identifies whether a training load is increasing, decreasing, or staying stable. Use this to catch creeping intensity early. ## Prompt Examples **Prompt:** ``` Calculate the ACWR for these weekly loads: [100, 120, 110, 150] with a 4-week chronic window. ``` **Response:** ``` ### ACWR Analysis Based on the loads provided, here is the current status: * **Latest Load:** 150 * **Chronic Baseline:** 110 * **Calculated ACWR:** **1.36** **Status:** 🟢 **Safe Zone** The athlete is currently within a healthy training range. No immediate adjustments are required. ``` **Prompt:** ``` What is the injury risk if my current ACWR is 1.6? ``` **Response:** ``` ⚠️ **High Risk Alert** A ratio of **1.6** puts the athlete in the **Danger Zone**. This indicates an excessive workload spike compared to their baseline. There is a high risk of injury if the current intensity is maintained. I recommend checking the training prescription to scale back volume immediately. ``` **Prompt:** ``` Analyze the trend for these ACWR values: [1.0, 1.1, 1.3, 1.4]. ``` **Response:** ``` ### Trend Analysis * **Trend:** 📈 **Increasing** * **Volatility:** ~0.15 The training load is steadily creeping up. While it may still be in a safe range, the upward trajectory suggests a need to monitor the athlete closely to ensure they don't hit a Danger Zone spike next week. ``` ## Capabilities ### Calculate ACWR values Get the exact ratio between recent and baseline training loads for any athlete. ### Spot training trends See if an athlete's workload is steadily creeping up or dropping off over time. ### Identify risk tiers Automatically flag when an athlete enters a high-risk Danger Zone or an Under-training state. ### Get coaching advice Receive specific training prescriptions to adjust volume or intensity based on current stress. ## Use Cases ### Soccer Team Injury Prevention A coach notices a defender's load is spiking. They ask the agent to check the risk tier and get a prescription to scale back the intensity. ### Marathon Training Analysis A runner wants to know if their last three weeks were too intense. The agent analyzes the ACWR series to confirm they're in the safe zone. ### Identifying Under-training A swimmer's load drops too low. The agent flags an Under-training status and suggests a specific volume increase to maintain fitness. ### Roster Readiness Summary A performance director asks for a summary of all high-risk athletes on the roster based on current trends to plan the week's sessions. ## Benefits - Stop guessing about overtraining. Use evaluate_risk_tier to see exactly when an athlete hits the Danger Zone based on real data. - Get data-backed coaching. Use generate_training_prescription to get specific advice instead of general rest orders for your athletes. - Spot trends before they hurt. detect_load_trend shows you if a load is creeping up before it becomes a physical problem. - Automate the math. calculate_acwr_series handles the complex ratio calculations between acute and chronic loads automatically. - Improve athlete availability. By identifying Under-training zones, you ensure athletes stay ready for competition without losing fitness. - Make faster decisions. Your agent can scan your entire roster and flag only the athletes who need immediate coaching intervention. ## How It Works The bottom line is you get a clear, data-backed plan to keep your athletes safe and performing at their peak. 1. Feed your agent raw training metrics like volume, intensity, or GPS data. 2. The Connector calculates the ACWR and checks for trends against the athlete's baseline. 3. You get a risk assessment and a specific training prescription for the next session. ## Frequently Asked Questions **How does the ACWR Analyzer help with injury prevention?** It identifies when an athlete's recent training load is spiking too fast compared to their long-term baseline. By flagging these 'Danger Zones,' it helps you catch potential injuries before they happen. **Can I use the ACWR Analyzer for individual athletes or teams?** Yes, it works for both. You can use it to monitor a single marathoner's training progress or scan an entire soccer roster to see who needs a workload adjustment. **What kind of data do I need to provide to the ACWR Analyzer?** You can provide any metric that represents training load, such as weekly mileage, total volume, intensity scores, or GPS-derived data points. **How does the training prescription work for my athletes?** The Connector looks at the current risk level and trend, then generates specific coaching advice. It tells you exactly how to adjust the next few days of training to stay safe. **Can it tell me if an athlete is under-training?** Yes, it identifies 'Under-training' zones. If an athlete's load drops too low, the Connector flags it so you can increase their volume and maintain their fitness. **Is the ACWR Analyzer for professional sports only?** It's for anyone who tracks training data. Whether you're a pro coach, a high school trainer, or a dedicated hobbyist, it provides the same sports science logic. **What is the purpose of the `calculate_acwr_series` tool?** It processes a sequence of weekly training loads to generate a series of ACWR values and summary statistics. **How does `evaluate_risk_tier` determine injury risk?** It applies specific thresholds to the current ratio: below 0.8 is Under-training, 0.8-1.3 is Safe, 1.3-1.5 is Moderate Risk, and above 1.5 is the Danger Zone. **Can I get coaching advice using this server?** Yes, the `generate_training_prescription` tool provides actionable instructions like 'Maintain', 'Increase', or 'Reduce' load based on your current ratio and trend.
