Test Intelligence Algorithms Skill

Purpose

Validates sports science algorithms (VDOT, TSS, TRIMP, FTP, VO2max, Recovery, Nutrition) for mathematical correctness and physiological plausibility.

CLAUDE.md Compliance

• ✅ Uses synthetic athlete data (no external dependencies)
• ✅ Deterministic tests with known outcomes
• ✅ Tests edge cases and error conditions
• ✅ Validates against research-based reference values

Usage

Run this skill:

• After modifying algorithm implementations
• After changing algorithm configurations
• Before releases
• When validating sports science accuracy
• After updating physiological constants

Prerequisites

• Rust toolchain
• Intelligence test fixtures in tests/

Commands

Expected Values:

CopyBeginner (5K in 30:00):    VDOT ≈ 30-33
Intermediate (5K in 22:30): VDOT ≈ 45-48
Elite (5K in 16:00):       VDOT ≈ 67-70

TSS/CTL/ATL/TSB (Training Load)

cargo test test_ftp_20min -- --nocapture

# Test 8-minute protocol
cargo test test_ftp_8min -- --nocapture

# Test ramp test
cargo test test_ftp_ramp -- --nocapture

Expected Values:

CopyBeginner:     FTP ≈ 150W (20min test: 158W × 0.95)
Intermediate: FTP ≈ 250W (20min test: 263W × 0.95)
Elite:        FTP ≈ 380W (20min test: 400W × 0.95)

# Test Cooper 12-minute test
cargo test test_cooper_test -- --nocapture

# Test VDOT to VO2max conversion
cargo test test_vdot_to_vo2max -- --nocapture

Expected Values:

CopyBeginner:     VO2max ≈ 35 ml/kg/min (Cooper: 1800m)
Intermediate: VO2max ≈ 49 ml/kg/min (Cooper: 2600m)
Elite:        VO2max ≈ 67 ml/kg/min (Cooper: 3400m)

Recovery & Sleep

Copy# Test recovery score calculation
cargo test test_recovery -- --nocapture

# Test sleep quality analysis
cargo test test_sleep_analysis -- --nocapture

# Test sleep stage scoring
cargo test test_sleep_stages -- --nocapture

Expected Values:

CopyWell-rested: Recovery score > 70, Sleep quality > 80%
Adequate:    Recovery score 50-70, Sleep quality 60-80%
Poor:        Recovery score < 50, Sleep quality < 60%

Nutrition

Copy# Test BMR/TDEE calculation
cargo test test_nutrition -- --nocapture
