Material and method:

A pre-experimental study was carried out with a treatment of a group consisting of 7 Officers in the reserve of the Army (59,57 ± 2,07 years old, body mass index of 26,76 ± 2,84 kg/cm2) and usual athletes (4,14 ± 1,35 training sessions per week). For 8 weeks, they replaced two of their usual training days for two days in which high-intensity concurrent training tasks were performed, with an average intensity (measured by Borg’s 10-point perceived effort scale) of 8,29 ± 0,74 points and an average execution time of 20,80 ± 5,77 minutes.

Results:

Statistically significant improvements (p < 0,05) were observed in the following qualities assessed by validated physical fitness tests: agility in two different directions of rotation (right, 3,81 ± 0,19 to 3,61 ± 0,21 seconds and left, 3,90 ± 0,17 to 3,68 ± 0,18 seconds); lower limb power (standing long jump, 1,61 ± 0,09 to 1,72 ± 0,09 cm); muscular strength of trunk (flexo rotation in 90», 39,14 ± 6,74 to 55,43 ± 10,94 reps) and upper limb (pull 18,71 ± 7,52 to 26,29 ± 9,91 reps and push, 21,29 ± 4,82 to 29,71 ± 6,85 reps) and cardiovascular resistance (recovery frequency, 96,57 ± 9,81 to 90,86 ± 8,69 pulsations min-1). Regarding the flexibility quality, although there were positive variations in the results, they were not statistically significant.

Conclusions:

The introduction of at least two weekly routines based on concurrent high intensity training is positive for senior military personnel, improving most of the physical qualities, especially strength manifestations.
