Getting fit
May 2009 Report from Dr. Andrew Middlebrooke
Since June 2008, Christina has been undergoing a series of physiological assessments in order to optimize her physical training and improve her chances of completing her Polar challenge. The latest assessment comes immediately after arriving home following Christina’s successful training mission to the North Pole. This allows us to look at the effect of the environment and physical work on her body’s physiological capacities. Here’s a summary of the changes that occurred from Pre- to Post-Polar expedition!
There was no significant change in Christina’s blood pressure pre v post the North Pole, however her resting heart rate was lower suggesting a training effect. Christina’s blood hemoglobin (iron) levels were much higher following the trip, which creates an increased capacity of the body to carry oxygen. This is a positive training adaptation.
Christina has lost a small amount of weight pre to post the North Pole trip (-1.7kg), which is very good considering the energy demands of the Polar environment and indicates that Christina has returned, she has managed to fuel herself effectively to replace the lost weight. This weight loss is reflected in a small but significant loss of body fat (2%).
In terms of body shape, we have noted a significant change in Christina’s waist (2.4cm) and hip (2.6cm) circumference, which reflects a change in body composition during the expedition.
Resting Metabolic Rate
There was no significant change in Christina’s resting metabolic rate (RMR) pre v post the North Pole that reflects little change in muscle mass during the expedition.
Exercise Data
This includes the data collected during your maximal exercise test, providing information about your physiological state at each exercise stage. At every exercise stage, Christina was more physiologically economical; with a lower heart rate, oxygen uptake, blood lactate and energy expenditure at each speed. This is a really positive training adaptation suggesting that Christina’s body found each level of exercise easier Post-Pole than before the expedition. This reflects the hard and sustained physical effort that Christina endured which acts as an intense and sustained training session.
There was also an improvement in Christina’s Lactate Turnpoint compared to pre-North Pole, which reflects the sustained high intensity work Christina endured. Interesting, her Lactate Threshold decreased slightly pre- and post the expedition which may reflect the lack of exercise stimulus at the easy to moderate intensity zone.

Il tasso metabolico a riposo
Questa è la somma di energia spesa mentre si è a riposo ed è misurata calcolando l anidride carbonica quando si espira.Lo stesso macchinario continuerà a misurare la quantità di energia o calorie che Christina brucerà quando l esercizio aumenta. Uno degli obiettivi principali sarà ottenere la quantità più bassa di calorie consumate durante l attività che Christina farà sciando al Polo Nord.
VO2 Max Questo è il consumo massimo di ossigeno .La preparazione cardiovascolare di Christina o la sua capacità aerobica sarà determinata misurando la sua respirazione mentre corre fino allo sfinimento.
Acido Lattico C è un momento in cui l acido lattico comincia ad accumularsi nel sangue a causa di…. Viene misurato prendendo piccoli campioni di sangue ad ogni livello di sforzo. Riuscire a capire l acido lattico permetterà alla squadra di esperti di fare un programma su misura per Christina per fare in modo che il punto di svolta sia ad un livello di sforzo molto più ampio. Mettendo a confronto questi test in tre mesi di incrementi è possibile stabilire l efficienza del programma e i progressi fatti da Christina così come mettere in luce parti che necessitano di più lavoro.
