欢迎大家加入开源鸿蒙跨平台开发者社区，一起共建开源鸿蒙跨平台生态。

健康指数的意义

健康指数是评估用户整体健康状况的重要指标。通过Cordova框架与OpenHarmony的数据分析能力，我们可以构建一个完整的健康指数评估系统。本文将介绍如何实现这一功能。

健康指数模型

javascript 复制代码

class HealthIndex {
  constructor(userId) {
    this.userId = userId;
    this.score = 0;
    this.components = {
      cardiovascular: 0,
      muscular: 0,
      flexibility: 0,
      endurance: 0,
      recovery: 0
    };
    this.lastUpdated = new Date().getTime();
  }
  
  calculateScore() {
    const weights = {
      cardiovascular: 0.25,
      muscular: 0.20,
      flexibility: 0.15,
      endurance: 0.25,
      recovery: 0.15
    };
    
    this.score = Object.keys(this.components).reduce((sum, component) => {
      return sum + (this.components[component] * weights[component]);
    }, 0);
    
    return this.score;
  }
  
  getHealthLevel() {
    if (this.score >= 90) return 'excellent';
    if (this.score >= 75) return 'good';
    if (this.score >= 60) return 'fair';
    if (this.score >= 45) return 'poor';
    return 'very-poor';
  }
}

HealthIndex类定义了健康指数的数据结构。通过calculateScore方法，我们计算了综合的健康指数。

心血管健康评估

javascript 复制代码

function assessCardiovascularHealth(heartRateData, workoutData) {
  const assessment = {
    score: 0,
    factors: {
      restingHeartRate: 0,
      maxHeartRate: 0,
      heartRateVariability: 0,
      vo2Max: 0
    }
  };
  
  // 评估静息心率
  const restingHR = getRestingHeartRate(heartRateData);
  assessment.factors.restingHeartRate = calculateRestingHRScore(restingHR);
  
  // 评估最大心率
  const maxHR = Math.max(...heartRateData.map(d => d.bpm));
  assessment.factors.maxHeartRate = calculateMaxHRScore(maxHR);
  
  // 评估心率变异性
  const hrv = calculateHeartRateVariability(heartRateData);
  assessment.factors.heartRateVariability = calculateHRVScore(hrv);
  
  // 评估VO2 Max
  const vo2Max = estimateVO2Max(workoutData);
  assessment.factors.vo2Max = calculateVO2MaxScore(vo2Max);
  
  assessment.score = Object.values(assessment.factors).reduce((a, b) => a + b) / 4;
  
  return assessment;
}

function calculateRestingHRScore(restingHR) {
  // 理想的静息心率是60-100 bpm
  if (restingHR < 60) return 100;
  if (restingHR < 70) return 90;
  if (restingHR < 80) return 80;
  if (restingHR < 100) return 70;
  return 50;
}

      powerOutput: 0
    }
  };
  
  // 评估力量训练频率
  const strengthWorkouts = workoutData.filter(w => 
    w.type === 'gym' || w.type === 'strength'
  );
  assessment.factors.strengthTraining = 
    Math.min((strengthWorkouts.length / 2) * 100, 100);
  
  // 评估肌肉耐力
  const avgDuration = calculateAverageDuration(strengthWorkouts);
  assessment.factors.muscleEndurance = 
    Math.min((avgDuration / 60) * 100, 100);
  
  // 评估功率输出
  const avgPower = calculateAveragePower(strengthWorkouts);
  assessment.factors.powerOutput = 
    Math.min((avgPower / 300) * 100, 100);
  
  assessment.score = Object.values(assessment.factors).reduce((a, b) => a + b) / 3;
  
  return assessment;
}

    factors: {
      yogaFrequency: 0,
      stretchingFrequency: 0,
      mobilityScore: 0
    }
  };
  
  // 评估瑜伽频率
  const yogaWorkouts = workoutData.filter(w => w.type === 'yoga');
  assessment.factors.yogaFrequency = 
    Math.min((yogaWorkouts.length / 1) * 100, 100);
  
  // 评估拉伸频率
  const stretchingWorkouts = workoutData.filter(w => 
    w.type === 'stretching' || w.description.includes('拉伸')
  );
  assessment.factors.stretchingFrequency = 
    Math.min((stretchingWorkouts.length / 2) * 100, 100);
  
  // 评估活动范围
  assessment.factors.mobilityScore = 
    assessMobility(workoutData);

      consistency: 0
    }
  };
  
  // 评估有氧能力
  const aerobicWorkouts = workoutData.filter(w => 
    w.type === 'running' || w.type === 'cycling' || w.type === 'swimming'
  );
  const avgDuration = calculateAverageDuration(aerobicWorkouts);
  assessment.factors.aerobicCapacity = 
    Math.min((avgDuration / 45) * 100, 100);
  
  // 评估训练量
  const totalDistance = aerobicWorkouts.reduce((sum, w) => sum + w.distance, 0);
  assessment.factors.trainingVolume = 
    Math.min((totalDistance / 100) * 100, 100);
  
  // 评估一致性
  const workoutDays = new Set(workoutData.map(w => 
    new Date(w.timestamp).toDateString()
  )).size;
  assessment.factors.consistency = 
    Math.min((workoutDays / 20) * 100, 100);
  
  assessment.score = Object.values(assessment.factors).reduce((a, b) => a + b) / 3;

    recommendations.push('建议增加有氧运动，如跑步或骑行，以改善心血管健康');
  }
  
  if (healthIndex.components.muscular < 70) {
    recommendations.push('建议增加力量训练，以增强肌肉力量和耐力');
