認識專業體組成分析儀


生物組抗分析測量電流通過身體遇到的阻抗(包含電阻、電抗、相位角)。方程式藉由阻抗和其他參數(例如:身高、年齡、體重)結合大量資料庫分析,計算身體的脂肪、肌肉、水分等其他體組成結果。

Multi-frequency

多頻率量測

傳統BIA儀器運用單頻率推算體組成,而事實上除了最常用的50kHz以外,其他高低頻率能讓儀器進行更精準的分析。低頻率能協助儀器分析細胞外液,而高頻率的穿透性使儀器也有辦法量測細胞內液。許多疾病都和水分有關,因此參考性高的水分計算為生物阻抗分析的關鍵。

Segmental measurements

肢段分析

早期的生物阻抗分析技術將人體視為單一圓形柱體,藉由腳對腳或手對手的路徑測量阻抗,藉此推算全身的結果。如果受測者的身型「標準」,是有一定參考性的。然而,對於其他身形就未必同樣適用。

上下半身差異大的受測者,用傳統技術測量的結果相對容易有較大的誤差,因為儀器並沒有真正進行全身的測量。因此啟德的人體組成分析儀運用肢段分析,能分別測量軀幹、右手、左手、右腳、左腳的數值,提供告具參考性的分析結果。

Abdominal Fat Analysis

腹部脂肪分析

肥胖相關疾病已逐漸成為需要關注的健康問題,越來越多人開始固定追蹤自己的體脂肪率。

其中,腹部脂肪和肥胖疾病相關聯性高,即使體重或BMI在正常範圍還是有可能內臟脂肪過高。

以往檢視內臟脂肪需要運用昂貴且有幅射性的電腦斷層掃描。藉由電腦斷層結果分析所建立的方程式,生物阻抗分析能推算出內臟脂肪,協助評估身體的肥胖狀況。

BIVA

生物阻抗向量分析 (BIVA)

水分是生物阻抗分析的核心變數。傳統生物阻抗分析運用大量資料庫分析,推算出體水分以及細胞內外液。若受測者的體水分狀況和資料庫有明顯差異,推算出來的數值參考性相對比較低。

然而,許多疾病都會影響體水分,這時必須運用生物阻抗向量分析 (Bioelectrical Impedance Vector Analysis / BIVA)。BIVA運用組成阻抗的電阻和電抗,將受測者的結果直接和對應族群比較後以圖示表現細胞及水分的狀態,不用假設受測者的水分正常。電阻電抗和體組成結果不同,為直接測量的數值而非推算的,因此水分異常的受測者也能使用。

Phase Angle

相位角

多數人體組成分析項目為「量」。肌肉量、脂肪量、水分等。但量相同不代表品質相同!芭蕾舞者、體質天生瘦、厭食症患者可能身高、BMI、體脂肪率都相似。但他們都一樣健康嗎?

「相位角」和細胞的健康程度相關性高,研究指出健康的族群和疾病族群的相位角有明顯的差異。將相位角和相似族群相比,能協助評估受測者的相對細胞健康程度;除了量的追蹤,提供一樣重要的品質分析。

1) How long does measurement take?

The MA601 uses 3 frequencies (5kHz, 50kHz, 250kHz), and will complete measurements within 45 seconds. The MA801 uses 5 frequencies (5kHz, 20kHz, 50kHz, 100kHz, 250kHz), and will complete measurements within 50 seconds.

2) How do I perform a scan?

Remove shoes and socks before scanning, and stand on measurement platform. Place feet on foot electrodes, and grasp handles firmly. Arms should be extended straight and slightly outward. For best results, try to keep still, and avoid speaking during your Charder body composition scan.

3) How often should I scan?

Body composition doesn't change significantly day-to-day. While frequency depends on each individual or program's needs, we generally recommend scanning once every 2-3 weeks to track and monitor progress.

4) When is the best time for a scan?

For best results, we following the guidelines below:

  • No vigorous exercise - Measure before exercise, not after! Exercise affects circulation and body water, which will affect measurement accuracy.
  • Use the bathroom - The effect of body waste on electrical conductivity is unknown, and may be interpreted as fat mass.
  • Avoid food and drink 2 hours before measurement - The effect of food and drink (digested and undigested) on electrical conductivity is unknown, and may be interpreted as fat mass.
  • Input data correctly - Charder body composition analyzers utilize input data (Height, Age, Gender) and measurement data (Weight, Impedance) to measure body composition. If input is incorrect, interpretation of results will also be inaccurate.

5) Why are my results different on other BIA devices?

We do not recommend directly comparing scan results between BIA devices manufactured by different brands.

Both the hardware and software of a BIA device can affect the data used by the algorithms for calculations of body composition. In addition, each manufacturer uses its own unique set of algorithms to estimate results, and as such variation between different brands is possible. As such, we recommend using your Charder body composition as a baseline measurement, using it to track changes.

6) Is BIA safe?

Bioelectrical Impedance Analysis is an established technology that has been used in the medical and fitness industry for many years. The electric current used for measurement is imperceptible; however, people with implanted electronic medical devices (e.g. pacemakers, artificial lungs) should NOT use BIA.

7) Can anyone perform a BIA scan?

BIA scans are not recommended for the following groups:

  • Pregnancy, Nursing Mothers - Body composition algorithms are based on “normal” healthy adults. Because body composition for pregnant women and nursing mothers is relatively inconsistent (particularly body water), results should be used for reference only.
  • Prosthetics, Amputation - Measurement current needs to pass through both hands and feet to operate correctly. If subject has amputated limbs or prosthetics, the scan will not function correctly.
  • Embedded Metal - Measurement utilizes electrical conductivity properties of the human body. Metal conductivity is higher than that of body tissue, and may cause inaccurate measurement results.

8) Will medication affect my results?

It is possible that some medications may affect your body composition measurement results. Notably, medications that affect body water and blood flow will likely affect overall results.

9) Will menstruation affect my results?

Body Composition does not remain consistent throughout the menstrual cycle. As such, scans during your cycle may not be as accurate.
