Abstract-Wristbands have been traditionally designed to track the activities of a single person. However there is an opportunity to utilize the sensing capabilities of wristbands to offer activity tracking services within the domain of team-based sports games. In this paper we demonstrate the design of an activity tracking system capable of detecting the players' activities within a one-to-one basketball game. Relying on the inertial sensors of wristbands and smartphones, the system can capture the shooting attempts of each player and provide statistics about their performance. The system is based on a twolevel classification architecture, combining data from both players in the game. We employ a technique for semi-automatic labeling of the ground truth that requires minimum manual input during a training game. Using a single game as a training dataset, and applying the classifier on future games we demonstrate that the system can achieve a good level of accuracy detecting the shooting attempts of both players in the game (precision 91.34%, recall 94.31%).

A mode-specific swimming protocol to assess maximal aerobic uptake (VO2maxsw) is vital to accurately evaluate swimming performance. A need exists for reliable and valid swimming protocols that assess VO2maxsw in a flume environment. The purpose was to assess: (a) reliability and (b) “performance” validity of a VO2maxsw flume protocol using the 457-m freestyle pool performance swim (PS) test as the criterion. Nineteen males (n = 9) and females (n = 10) (age, 28.5 ± 8.3 years.; height, 174.7 ± 8.2 cm; mass, 72.9 ± 12.5 kg; %body fat, 21.4 ± 5.9) performed two flume VO2maxsw tests (VO2maxswA and VO2maxswB) and one PS test [457 m (469.4 ± 94.7 s)]. For test–retest reliability (Trials A vs. B), moderately strong relationships were established for VO2maxsw (mL·kg−1·min−1)(r= 0.628, p = 0.002), O2pulse (mL O2·beat−1)(r = 0.502, p = 0.014), VEmax (L·min−1) (r = 0.671, p = 0.001), final test time (sec) (0.608, p = 0.004), and immediate post-test blood lactate (IPE (BLa)) (0.716, p = 0.001). For performance validity, moderately strong relationships (p < 0.05) were found between VO2maxswA (r =−0.648, p = 0.005), O2pulse (r= −0.623, p = 0.008), VEmax (r = −0.509 p = 0.037), and 457-m swim times. The swimming flume protocol examined is a reliable and valid assessment of VO2maxsw., and offers an alternative for military, open water, or those seeking complementary forms of training to improve swimming performance.

This paper aims to highlight how to use the computerized video analysis for learning the sports technique key elements of the start in swimming in the case of the students in higher education of other profiles. This scientific approach entailed the organization of an ascertaining experimental study, using the following research methods: bibliographic study of the specialized literature, video computerized method by means of Pinnacle Studio, Kinovea and Physics ToolKit programs, method of movement postural orientation, statistical-mathematical method which uses the KyPlot program and the method of graphical representation of results. The research was conducted from October 2017 to January 2018 and included 12 students (second-year - series no. 2) of the Faculty of General Medicine. The results of the study show the muscle strength development of arms, abdomen and legs of the students under research. The use of the video computerized method highlights and identifies the kinematic and dynamic characteristics of sports technique key elements used in swimming start regarding the launching posture, multiplication of body posture (flying through the air) and concluding body posture (entering the water). The propulsion and going out of water will be studied depending on the specific swimming style chosen by the students. The effective use of the computerized video analysis that deepens the understanding of sports technique phasic structure will allow the processing of the modern didactical programs for swimming learning. The modern research methods used in the video computerized analysis of sports technique of the start in swimming are an important help for the measurement, analysis and evaluation of the kinematic and dynamic structure of all swimming styles.
