Wearable Metabolic System for both Field and Laboratory Testing

 “Introducing K5, the 4th generation of the most popular wearable metabolic system,  a breakthrough in the field of exercise physiology and human performance assessment.”

1987 ... introducing K2, the first compact Metabolic  system (O2 consumption) for field testing 

1994 ... introducing K4, the first mobile metabolic  system (both O2 and CO2) with patented  dynamic mixing chamber 

1997 ... introducing K4 b², the first “breath by breath”  mobile metabolic system with integrated GPS 

2014 ... K5 wear it!

It has been almost 30 years since COSMED  introduced the first generation of compact  metabolic systems. During this time we have  collected significant feedback and ideas  directly from the most important institutions  around the world. The result of such an experience has been  carefully implemented in a complete new  piece of technology incorporating latest  design and providing researchers, sport  professionals and clinical users new ways to  explore human exercise physiology. COSMED is proud to introduce K5, the 4th  generation of the most popular wearable  metabolic system, a breakthrough in the field  of exercise physiology and human performance assessment. The K5 is the most innovative and versatile  metabolic system ever created. K5 reaps the  benefits of more than 25 years of experience  with metabolic systems. K5 features a list of  new and unique characteristics that expand  the scope of metabolic testing from clinical  exercise testing to performance assessment.

Accuracy & Reliability K5 has been designed with a focus on accuracy and usability. With this new generation  of metabolic system COSMED introduces  new patented technologies for gas exchange  measurements. IntelliMET™ (Intelligent Dual Metabolic Sampling Technology  - US Patent 9581539) sets a new standard in metabolic measurements by providing a dual  gas sampling system able to provide both  micro-dynamic mixing chamber and breath  by breath gas exchange measurements.

With IntelliMET (option) users can select  between the mixing chamber and the breath  by breath mode depending on the protocol  type, research or other factors. K5 features proven and reliable, highly linear  and rapid response O2 (GFC) and CO2 (NDIR)  sensors. The O2 sensor has an average lifespan  of 12 months. Once exhausted, the O2 cell  is replaced by the user without the need of  technical assistance.

Design 

■ Designed according to IP54 standard, K5  is a tough/rugged device. Rubber seals  protect the body, connectors and ports  against water, moisture and dust intrusion.

■ Single-body device, reduces weight  (900g including battery) and simplifies  setup. 

■ 3.5” touch-screen LCD (320 x 240) with  LED-back-lit TFT for optimal viewing in  all lighting conditions. 

■ Resistive touch-screen technology  allows use in outdoor conditions with  either gloves or wet fingers. 

■ The integrated tripod mount (1/4”-20  UNC) located at the bottom of the  unit allows the K5 to be mounted on  several standard supports (i.e for biking,  outdoor activities and sports or when  used in lab testing) providing extreme  versatility.

User Interface 

■ 4 keys keyboard for rapid access to  frequent functions (On/Off and Rec  buttons, Back/Check and Home/Marker  keys). 

■ Two large compartments located on the  top of K5 allow users to easily access the  O2 sensor, the battery and the SD-card  slot. 

■ Intuitive user interface allows simple  navigation and quick access to all commands and features, with big easy-toclick icons  

■ Status bar provides information regarding time, date, battery status, Bluetooth®  (on/off), GPS and notification icons (for  QC messages, warnings etc.). 

■ Li-ion “smart battery” with an LCD showing charge status. Battery life is up to 4  hours. Batteries are easily replaceable.

”K5 complies with IP54 standard, it has been specifically designed for outdoor use  and provides protection against heavy water (rain, sweat) or dust.“

Wearable Great attention has been paid to simplify  subject setup and improve ergonomics. The  preferred position of the device is mounted  on the back of the subject. 

■ New harness design provides great  comfort and ergonomics during dynamic field testing. 

■ The harness consists in 2 pieces: the  skeleton is a robust/rigid/rugged part  adjustable in length; the soft piece is  made of breathable material, is detachable and washable, providing great  comfort while walking or running.

Navigation The K5 features a standard integrated 10Hz  GPS/QZSS receiver, with high position and  speed accuracy.  

■ K5 accurately measures both altitude  and grade by using the internal barometric pressure sensor coupled with  GPS readings.

■ Data can be monitored real time on K5  display and, eventually, downloaded  (together with K5 metabolic parameters) in a dedicated interactive browser  or in mapping software such as Google  Earth.

Wireless Connectivity Great attention has been given to allow K5  more efficient wireless data transmission  and seamless integration with other devices.  Provided with wirelss data transmission K5  can be controlled via remote and integrated  with Bluetooth® external peripherals. K5 is also fully compatible with ANT+ technology. ANT+ is a wireless technology that  allows monitoring devices to communicate  each other and integrating and synchronizing data in a single source. 

■ Standard Bluetooth 2.1 + EDR with data  transmission range ~10m in line-of-sight  (standard). 

■ Long Range Bluetooth 2.1 + EDR with data  transmission range up to 1000 m in line-ofsight (option). 

■ ANT+ engine for integration with external  devices (SRM, CycleOps, Garmin etc.).  Up to 8 channels simultaneously and  compatible with 5 profiles (Bike Power  & Torque, Bike Speed & Cadence, HR  monitor, Muscle Oxygen Monitor, Stride  Based Speed & Distance)1 .

Data Management & Software Every K5 comes with the OMNIA Metabolic  Module of OMNIA, the new modular software  suite from COSMED with an intuitive and  innovative user interface.  OMNIA allows the user to operate complex  equipment without requiring long learning  paths.
