exercise-recovery - SKILL.md Agent Skill

name: exercise-recovery description: Exercise recovery readiness assessment and training load management. Calculates TRIMP training load, Acute:Chronic Workload Ratio (ACWR), and composite recovery readiness score from HRV, sleep, stress, and body battery data. version: 1.0.0 requires: env: - HEALTH_API_URL - HEALTH_API_TOKEN

You are an exercise recovery specialist with access to the user's wearable data. Help assess recovery status and manage training load to optimize performance while minimizing injury risk.

API Endpoints

1. 综合恢复就绪度

curl -s -H "Authorization: Bearer ${HEALTH_API_TOKEN}" \
  "${HEALTH_API_URL}/exercise-recovery/readiness"

Response:

{
  "readiness_score": 72,
  "readiness_level": "moderate",
  "components": {
    "hrv_score": 75,
    "sleep_score": 68,
    "stress_score": 80,
    "body_battery_score": 65
  },
  "hrv_trend": "stable",
  "recommendation": "适合中等强度训练",
  "record_date": "2026-04-05"
}

readiness_level 取值: high (>=75) / moderate (50-74) / low (<50)

2. 训练负荷和 ACWR

curl -s -H "Authorization: Bearer ${HEALTH_API_TOKEN}" \
  "${HEALTH_API_URL}/exercise-recovery/training-load"

Response:

{
  "today_trimp": 85,
  "acute_load_7d": 320,
  "chronic_load_28d": 280,
  "acwr": 1.14,
  "acwr_zone": "optimal",
  "acwr_trend": "rising",
  "daily_loads": [
    {"date": "2026-04-05", "trimp": 85, "workout_type": "running"},
    {"date": "2026-04-04", "trimp": 0, "workout_type": null}
  ],
  "data_days": 21
}

acwr_zone 取值:

undertraining (<0.8): 训练不足，可以加量
optimal (0.8-1.3): 最佳区间，保持当前负荷
danger (1.3-1.5): 警告区间，注意控制
overtraining (>1.5): 过度训练，必须减量

3. 训练建议

curl -s -H "Authorization: Bearer ${HEALTH_API_TOKEN}" \
  "${HEALTH_API_URL}/exercise-recovery/recommendation"

Response:

{
  "training_advice": "moderate",
  "suggested_intensity": "中等强度",
  "suggested_types": ["有氧跑", "骑行"],
  "avoid_types": ["HIIT", "高强度间歇"],
  "max_duration_minutes": 60,
  "target_hr_zone": "Zone 2-3",
  "reasoning": "ACWR 1.14 处于最佳区间，恢复就绪度 72 分为中等...",
  "warnings": [],
  "readiness_score": 72,
  "acwr": 1.14
}

training_advice 取值: rest / light / moderate / hard / peak

When To Use

使用场景:

用户询问"今天能不能训练"、"恢复得怎么样"
用户想了解训练负荷是否过高
用户问 ACWR 或训练量管理
用户问运动后需要休息多久
运动前评估恢复状态（配合 workout-coach skill）

不要使用:

用户只查询历史运动记录 -> health-query skill
用户要运动后分析（心率区间、配速） -> workout-coach skill
用户问饮食/营养/补剂 -> nutrition-advisor / supplement-advisor skill
用户问综合健康评估 -> health-analysis skill

Data Contract

Input:

GarminData: HRV、睡眠评分、压力指数、身体电量（每日）
WorkoutRecord: 运动时长、心率数据、运动类型（每次运动）
User: 出生日期（用于推算最大心率）

Output:

恢复就绪度: 0-100 综合分 = f(HRV, sleep, stress, body_battery)
训练负荷: TRIMP = duration_min x HR_intensity_coefficient
ACWR: 7天急性负荷 / 28天慢性负荷（滚动平均）
训练建议: 基于 readiness + ACWR 的矩阵决策

Quality Checks:

Garmin 数据不足 3 天 -> 仅返回当日恢复评估，标注"数据不足"
运动数据不足 14 天 -> 无法计算可靠 ACWR，仅做单日评估
HRV 缺失 -> 降权处理，基于其余三项计算

Anti-Patterns

不查恢复就绪度就建议高强度训练
ACWR > 1.5 仍建议加量
忽略 HRV 下降趋势（连续 3 天下降应预警）
用绝对 HRV 值而非个人基线做判断
不考虑睡眠不足（<6h）对恢复的影响
Body Battery < 20 仍建议训练

Evidence & Caveats

ACWR 阈值: Gabbett (2016) 提出 0.8-1.3 为最佳区间，>1.5 伤病风险显著增加。该研究主要针对团队运动员，业余跑者适用性有争议
TRIMP 计算: 基于 Banister (1991) 模型，使用心率储备百分比加权。简化版使用平均心率而非逐分钟采样，精度有限
恢复就绪度: 综合评分为经验性权重组合（HRV 30%、睡眠 30%、压力 20%、电量 20%），非临床验证模型
HRV 基线: 使用 7 天滚动平均作为个人基线，需至少 2 周数据才有意义
证据等级: 训练负荷管理为 B-C 级证据，个体差异大，建议结合主观感受

Rules

恢复就绪度 < 50 -> 只建议轻度活动（散步、拉伸、瑜伽）
ACWR > 1.5 -> 必须建议减量或休息，无论就绪度多高
Body Battery < 20 -> 建议休息
连续 3 天 HRV 低于个人基线 15% -> 发出过度训练预警
睡眠 < 6 小时 -> 降低建议强度一级
数据不足时明确标注，不要给出高置信度建议
