PRIMARY outcome

Timeframe: During the basic military training (18 weeks)

Population: The overall number of participants analyzed is smaller than the corresponding numbers in the participant flow module, because only participants who finished the whole 18-weeks basic military training were included in the analysis.

All injuries which are registered in the patient's medical record are collected and classified. A classification system which takes into account anatomical site, circumstances of the accident, and severity of the injury is used.

Number of Participants With Injuries	184 participants with injuries	172 participants with injuries

SECONDARY outcome

Timeframe: Weeks 2, 10 and 16 of the basic military training

Population: The overall number of participants analyzed is smaller than the corresponding number in the participant flow module, because only participants who completed all three fitness tests were included in the analysis.

Physical Fitness is measured with the Swiss physical fitness test battery (SPFTB). The SPFTB contains a progressive endurance run, a trunk muscle strength test, a standing long jump, a seated shot put, and a one-leg standing test. From the results of those performance tests (0 to 25 points each), a total fitness score is calculated (sum of all points). The minimum total score (worst result) is 0 points, the maximum total score (best result) is 125 points. A detailed description of the SPFTB can be found in the publication of Wyss, Marti, Rossi, Kohler and Mäder (2007).

SECONDARY outcome

Timeframe: Weeks 2, 10 and 16 of the basic military training

Population: The overall number of participants analyzed is smaller than the corresponding number in the participant flow module, because only participants who the psychological questionnaires at all three time points were included in the analysis.

2 questionaires concerning resilience were used: The Resilience Scale 11 (Schumacher, Leppert, Gunzelmann, Strauss \& Brähler, 2005) and the Brief Resilience Scale (Smith, Dalen, Wiggings, Tooley, Christopher \& Bernard, 2008). A mean was calculated for each time point. The total score ranges from 1 (worst result) to 7 (best result).

SECONDARY outcome

Timeframe: During the basic military training (18 weeks)

Population: The overall number of participants analyzed is smaller than the corresponding number in the participant flow module, because only participants from whom military marks were available for the whole basic military training were included in the analysis.

Military marks are given by superior Army personnel. The total score ranges from 1 (insufficient) to 5 (excellent). In total, three marks are given during the whole basic military training (after 7, 11 and 16 weeks). Data from those three time points are combined in a single value (mean).

SECONDARY outcome

Timeframe: Week 1 of the basic military training and 3 months after finishing the basic military training

Population: The overall number of participants analyzed is smaller than the corresponding number in the participant flow module, because only participants who completed the questionnaire at both time points were included in the analysis.

OTHER_PRE_SPECIFIED outcome

Timeframe: During the whole basic military training (18 weeks)

Duration of each sport session was registered in a questionnaire by the military personnel. The minimum would be 0 minutes of sport per week, for the maximum the scale is open-ended. Data of sport lessons during the whole basic military are combined and presented as a mean value for each group.

OTHER_PRE_SPECIFIED outcome

Timeframe: Weeks 2 - 9 of the basic military training

Population: The overall number of participants analyzed is smaller than the corresponding number in the participant flow module, because only an exemplary sample of 40 participants per group were chosen to wear the sensors due to financial reasons.

Daily energy expenditure was measured using two accelerometers and one heart rate sensor. Data from weeks 2-9 of the basic military were combined and a single value (mean) was calculated for each group.
