Clinical Trial Summary

The purpose of the study is to measure the effects of a 6 week sport specific BET intervention on physical and cognitive performance parameters in elite orienteering athletes.

Description:

The purpose of the study is to measure the effects of a 6 week sport specific BET intervention on physical and cognitive performance parameters in elite orienteering athletes.

The study is constructed as a cross-over design, where participants function as their own control condition. The control condition (the first period) and the intervention (the latter period) consists of a 6 week training period, both leading up to a prioritized international competition. In the control condition participants will train normally leading up to the European Championships. During the intervention period participants will implement 3 sessions per week of a specially designed brain endurance program, leading up to the World Championships. To investigate the effect on all endpoints, physical and cognitive tests are conducted before and after the training periods.

Intervention

Other:
• Brain Endurance Training
Six week period with three weekly blocks with a 20 min brain endurance training program following a regular HIT session. Before the HIT session questionnaires are completed to measure the motivation for the HIT session and the current state of mood. In between the HIT session and the RCA session, questionnaires are completed to measure the experienced workload of the HIT session, the current state of mood, and the motivation for following the RCA session. Immediately after the RCA session, questionnaires are completed to measure the experienced workload of the RCA session and the current state of mood.
• Control
No intervention

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in 5000 m run performance (time)	Self Paced endurance test (physical test part 1) To measure maximal self-paced endurance performance, a track and field test will be performed. This test is completed on a standard athletic track measuring 400m.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Primary	Change in Cognitive performance #1 (score)	Change in Inhibition task performance (cognitive test part 1a) This cognitive test consists of the Stroop colour-word task. Participants perform this task on a computer whilst sitting in a quiet and dim lit room. Four words (yellow, blue, green, red) are serially presented on the screen until the participant validates an answer which is followed by a 1,500 ms interval.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Primary	Change in Cognitive performance #2 (score)	Route Choice Assessment program (RCA) (cognitive test part 1b) Participants perform the RCA on a computer whilst sitting comfortably in a quiet and dim lit room. The RCA program is a specially designed computer program. The program contains approximately 1500 different orienteering legs.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Secondary	1000 m submaximal running performance	Lactate levels during a submaximal 1000 m run is measured to assess physiological stress during the submax test.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Secondary	Mood change	The Brunel Mood Scale (BRUMS) is used to assess mood. This questionnaire, which is based on the Profile of Mood States, contains 24 items (e.g., angry, uncertain, miserable, tired, nervous, energetic) divided into six respective subscales: anger, confusion, depression, fatigue, tension, and vigor. The items are answered on a 5-point Likert scale (0 not at all, 1 a little, 2 moderately, 3 quite a bit, 4 extremely), and each subscale, with four relevant items, can achieve a raw score in the range of 0 to 16 with a higher number indicating a stronger expression. Because of the particular interest in mental fatigue in the present study, we specify that an alteration in the subscales for fatigue and vigor is an indication of mental fatigue.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Secondary	Subjective workload change	The National Aeronautics and Space Administration Task Load Index (NASA-TLX) rating scale is used to assess subjective workload. The NASA-TLX is composed of six subscales: mental demand (How much mental and perceptual activity was required?), physical demand (How much physical activity was required?), temporal demand (How much time pressure did you feel due to the rate or pace at which the task occurred?), performance (How much successful do you think you were in accomplishing the goals of the task set by the experimenter?), effort (How hard did you have to work to accomplish your level of performance?) and frustration (How much irritating or annoying did you perceive the task?). The participants scores on each of the items on a scale divided into 20 equal intervals anchored by a bipolar descriptor (e.g. high/low). This score is multiplied by 5, resulting in a final score between 0 and 100 for each of the subscales with a higher number indicating a higher workload.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
Secondary	Motivation change	Motivation is measured using the visual analogue scale (VAS) with 1 item (How motivated do you feel for the upcoming task?) The VAS scale consists of a 100-mm line anchored by a bipolar descriptor (not at all / a lot), on which participants mark their answer. Participants are instructed to answer VAS regarding their feeling of motivation for the upcoming task. The mark is transferred to a final score between 0 and 100 corresponding to the actual physical placement of the mark on the scale. A higher number indicating a high amount of motivation.	At baseline, after 6 (after CON) and after 12 (after BET) weeks
