While tactical performance in competition has been analysed extensively, the assessment of training processes of tactical behaviour has rather been neglected in the literature. Therefore, the purpose of this study is to provide a methodology to assess the acquisition and implementation of offensive tactical behaviour in team handball. The use of game analysis software combined with an artificial neural network (ANN) software enabled identifying tactical target patterns from high level junior players based on their positions during offensive actions. These patterns were then trained by an amateur junior handball team (n = 14, 17 (0.5) years)). Following 6 weeks of tactical training an exhibition game was performed where the players were advised to use the target patterns as often as possible. Subsequently, the position data of the game was analysed with an ANN. The test revealed that 58% of the played patterns could be related to the trained target patterns. The similarity between executed patterns and target patterns was assessed by calculating the mean distance between key positions of the players in the game and the target pattern which was 0.49 (0.20) m. In summary, the presented method appears to be a valid instrument to assess tactical training.

Background: Hormonal levels in women are influenced by exercise intensity and modality. Methods: This 10-week study compared high-intensity interval training (HIIT) and traditional resistance training (TRT) in 72 young women. Hormonal levels (estrogen, testosterone, FSH, prolactin, and LH) were measured pre- and post-intervention. Results: Both groups showed significant increases in estrogen (HIIT: 150%; TRT: 72.3%) and decreases in testosterone (HIIT: 58%; TRT: 49%), FSH (HIIT: 6%; TRT: 7.7%), and PL (HIIT: 5%; TRT: 2.1%). There are no significant changes in LH. Conclusions: HIIT and TRT effectively modulate hormonal profiles, potentially benefiting reproductive and metabolic health.

Background: Hormone levels can be determined according the prevalence of a balance between generation metabolism and clearance rates. High-Intensity Interval Training (HIIT) can affect this balance through a variety of mechanisms, including competition-associated stress, diet, body composition, heat production and hypoxia. Aims: The present study aimed to evaluate the impact of HIIT on the Health hormones of femininity and fertility in young women. Methods: The study was comprised of Eighteen females aged 18.06 ± 0.128 years old. The participants were subjected to an eight-week training program (3 sessions/week, two hours (h) after lunch). Participants underwent basal pre-and post-exercise intervention tests, such as reproductive and trophic hormones. Results: The results revealed that 143.16% increased estrogen levels and a 62.12% reduction in testosterone levels . No significant differences were detected in Luteinizing hormone (LH) and Prolactin (PRL) between participants. Conclusions: HIIT exercise training in young women decreases testosterone levels and increases estrogen levels, with no effect on trophic hormones (LH, PRL).
