ABSTRACT
BACKGROUND: Actual studies in military training support the use of new methodological approaches such as high intensity interval training and inverse periodization training rather than conventional approaches. However, the application and analysis of success of these new methodologies are as yet unknown.METHODS: The military adapted the civil reverse periodization training system, composed of 6 wk and five sessions per week. For the first 3 wk soldiers performed two sessions with the objective of increasing the maximal strength of the upper and lower body muscles, and three sessions of short high-intensity interval training (HIIT). In the following 3 wk they combined two endurance HIIT and two resistance HIIT sessions with military equipment while conducting a military task.RESULTS: After the training a significant body mass index decrease was found, along with an increase in lower limb muscular strength, aerobic and anaerobic performance, resilience, stress tolerance, and psychological flexibility. Regarding the ratio of acceptance there was an increased ratio compared to previous years of 7%. In addition, married soldiers with children presented greater resilience, stress tolerance, psychological flexibility, and a higher ratio of success.DISCUSSION: Accepted soldiers presented greater psychological status and stress tolerance, highlighting the importance of the work of the unit psychologists to reinforce and monitor the psychometric profile of the soldiers as well as their intrinsic characteristics of personality and emotionality. The greater baseline physical condition and higher performance in all physical tests proves how reverse periodization training models are a great stimuli and training approach in soldiers.Tornero-Aguilera JF, Gregório Pelarigo J, Clemente-Suarez VJ.

Aims: To compare the effect of a bout of high-intensity interval training (HIT) with a bout of moderate-intensity continuous training (MICT) on glucose concentrations over the subsequent 24-hour period. Methods: Fourteen people with type 1 diabetes [T1D (duration of T1D, 8.2 ± 1.4 years)], all on a basal-bolus regimen, completed a randomized, counterbalanced, crossover study. Continuous glucose monitoring was used to assess glycemic control after a single bout of HIT (six 1-minute intervals) and 30 minutes of MICT on separate days compared with a nonexercise control day (CON). Exercise was undertaken after an overnight fast with omission of short-acting insulin. Capillary blood glucose samples were recorded before and after exercise to assess the acute changes in glycemia during HIT and MICT. Results: There was no difference in the incidence of or percentage of time spent in hypoglycemia, hyperglycemia, or target glucose range over the 24-hour and nocturnal period (12:00 am to 6:00 am) between CON, HIT, and MICT (P > 0.05). Blood glucose concentrations were not significantly (P = 0.49) different from pre-exercise to post-exercise, with HIT (0.39 ± 0.42 mmol/L) or MICT (-0.39 ± 0.66 mmol/L). There was no difference between exercise modes (P = 1.00). Conclusions: HIT or 30 minutes of MICT can be carried out after an overnight fast with no increased risk of hypoglycemia or hyperglycemia. If the pre-exercise glucose concentration is 7 to 14 mmol/L, no additional carbohydrate ingestion is necessary to undertake these exercises. Because HIT is a time-efficient form of exercise, the efficacy and safety of long-term HIT should now be explored.

Overweight and obesity may lead to serious health problems, and negatively affect everyday functioning in physical, psychological and social spheres. The high prevalence of overweight and obesity in children and adolescents constitutes a huge public health burden. One way of designing and implementing behavioral interventions aimed at the reduction of adipose tissue is to promote physical activity. In this review we present recommendations regarding the planning, monitoring and implementation of intervention programs involving controlled physical activity. Considering specific individual determinants and needs in terms of improving children's health, physical condition and physical performance, we have separately discussed recommendations for interventions involving aerobic and anaerobic exercises with moderate and high intensity, including high-intensity interval training (HIIT). We have also focused on the role of resistance training. Finally, we have emphasized that children and adolescents with overweight or obesity should also be motivated to undertake activities referred to as non-exercise activity thermogenesis (NEAT).
