Studies on Orienteering


While studying and in need of Orienteering I searched "Orienteering" at Pubmed, the medical searchtool and found some interest studies that I post. I didn't check its validity, just copy-pasted some paragraphs from the abstracts that I found.

The other major findings were that prior to competition, superior orienteers reported use of higher self-efficacy, more positive outcome expectations and more task demand orientation than their less successful counterparts. Top orienteers coped more successfully with pre-competition anxiety by lowering their anxiety to a more moderate level prior to the actual performance. here

High aerobic power in orienteers (up to 63 and 76 ml/kg/min in women and men, respectively) is coupled with lower anaerobic performance. While leg strength is generally not high when compared with other athletic specialties, female orienteers have relatively good leg flexion strength. The energy cost of running is greatly increased in rough terrain. Oxygen cost was 26% higher while running in a forest when compared with road running. Biomechanical differences in stride pattern contribute towards this increased demand. Despite the high energy demands during competition, orienteers pace themselves such that their mean heart rate remains within the range of 167 to 172 beats/min, despite large fluctuations. The rough terrain encountered in orienteering results not only in a high energy cost but also in a higher incidence of sport-specific injuries, particularly to the ankle. here

Orienteers, as compared to nonathletes, showed a faster reaction speed and a complex pattern of attentional differences depending on the time constraints of the attentional task, the demands on endogenous attentional control, and the presence or absence of a concomitant effortful motor task. Results suggest that older expert orienteers have developed attentional skills that outweigh, at least at rest, the age-related deficits of visual attentional focusing. here

More experienced orienteers attended to the map markedly more while moving and spent less time stationary than less experienced orienteers. The participants' performance was significantly related to the ability to attend to the map while moving. The strategic control of attention is proposed to explain this ability. It is proposed that attentional training might enhance performance in sports characterized by multiple and dynamically varying elements. here

Correlation analyses showed a relationship between a high anaerobic threshold and few orienteering mistakes here

We conclude that daily orienteering competitions per se do not seem to create risks for developing a state of hormonal imbalance or significant decrease in glycogen when the carbohydrate supply is appropriate. here

The magnitudes of the age-related slowing of orienteering speed and of the difference in orienteering speed between males and females aged 45 years and over were greater than those reported for the other endurance running events. This may reflect the physical demands of running in orienteering terrain, tactical and cognitive aspects of the sport, or sociocultural aspects of the participating population. here

Inspired by the Tour de France I've been off-road cycling a lot, mainly uphill. I'm feeling physically well and in the 1st of August I'll start running more seriously again. I'm really missing navigating with a map!
