The purpose of this study was to analyze the effect of varying the number of players in physiological responses, including heart rate, the subjective perception of muscular effort and the impact of different small-sidded games in Futsal. The study sample consisted of 10 Futsal players of senior level (age 22.7 ± 7.15, height 173.8 ± 3.73, weight 68.10 ± 5.93; HRmax 201.7 ± 13.9 bpm). In each game, the protocol consisted of four sets of 4 minutes separated by 2 minutes of active recovery, accounting in its entirety 22 minutes. The perceived exertion was performed during periods of active recovery. The tests of squat jump and countermovement jump tried to analyze the flight time and jump height before and after each game. To determine the HRmax, the players were subject to testing yo-yo intermittent recovery test. The time spent in heart...
This study aims to analyze and characterize the long-term athlete development of Portuguese futsal players. To this end, a structured interview was conducted with a total of 15 athletes of different competitive levels that constituted our sample (5 Portuguese international athletes, 5 athletes of the 2nd national division and 5 athletes of district divisions).

This final paper is the highest point of a long and difficult path, where curiosity
and professionalism always made me search for knowledge. The internship
revealed to be a crucial element of my training, where all theoretical and
practical knowledge that I have acquired during my degree was applied in a real
work environment. However, these theoretical skills could only become truly
useful and important when effective in a practical context. Therefore, the main
goal of the internship was the acquisition of skills and knowledge, which allowed
me to perform with all the required professionalism, the role of sports coach.
The core of my final paper is about my personal experience at SCP
(Sporting Clube de Portugal) and the linkage of that experience to theory. In
order to do that linkage, a little analysis of data was carried o...
