The aim of the current study was to analyze the temporal effects that unsportsmanlike fouls may have on basketball teams’ scoring performance under consideration of context-related variables. The authors analyzed 130 unsportsmanlike fouls from 362 elite basketball games (men’s and women’s Olympic Games, European and World Championships). The context-related variables studied were score-line, quality of opposition, timeout situation, minutes remaining, and player status. The data were analyzed with linear-regression models. The results showed that both teams (the team that made the foul and the opponent) had similar positive scoring performances during 1 and 3 ball possessions after the unsportsmanlike foul (short-term effect). However, 5 ball possessions after the foul (midterm effect), the team that made the foul had a scoring disadvantage (−0.96) and the opponent team an advantage (0.78). The context-related variable quality of opposition was significant only during 1 ball possession, with negative effects for the team that made the foul and positive effects for the opponent. The final outcome showed a positive effect for score-line when the unsportsmanlike foul was made (0.96) and for quality of opposition (0.64).

The interday reliability of the Intelligent Device for Energy Expenditure and Activity (IDEEA) has not been studied to date. The study purpose was to examine the interday variability and reliability on two consecutive days collected with the IDEEA, as well as to predict the number of days needed to provide a reliable estimate of several movement (walking and climbing stairs) and nonmovement (lying, reclining, and sitting) behaviors and standing in older adults. The sample included 126 older adults (74 women) who wore the IDEEA for 48 hr. Results showed low variability between the 2 days, and the reliability was from moderate (intraclass coefficient correlation = .34) to high (.80) in most of movement and nonmovement behaviors analyzed. The Bland–Altman plots showed high–moderate agreement between days, and the Spearman–Brown formula estimated that 1.2 and 9.1 days of monitoring with the IDEEA are needed to achieve intraclass coefficient correlations ≥ .70 in older adults for sitting and climbing stairs, respectively.

Purpose: To quantify the magnitude of the association between the same variables of the force–velocity (FV) profile and the performance variables (unloaded-squat-jump height and 20-m sprint time) obtained during jumping and sprinting testing and to determine which mechanical capacity (ie, maximum force [F 0], maximum velocity [V 0], or maximum power [P max]) presents the highest association with the performance variables. Methods: The FV profile of 19 elite female soccer players (age 23.4 [3.8] y, height 166.4 [5.6] cm, body mass 59.7 [4.7] kg) was determined during the jumping and sprinting tasks. The F 0, V 0, FV slope, P max, and FV imbalance (difference respect to the optimal FV profile in jumping and the decrease in the ratio of horizontal force production in sprinting) were determined for each task. Results: Very large correlations between both tasks were observed for P max (r = .75) and the performance variables (r = −.73), as well as moderate correlations for V 0 (r = .49), while the F 0 (r = −.14), the FV slope (r = −.09), and the FV imbalance (r = .07) were not significantly correlated between both tasks. The P max obtained during each specific task was the mechanical capacity most correlated with its performance variable (r = .84 in jumping and r = .99 in sprinting). Conclusions: The absence of significant correlations between some of the FV relationship parameters suggests that, for an individualized training prescription based on the FV profile, both jumping and sprinting testing procedures should be performed with elite female soccer players.

The aims of the current study were (a) to analyze the differences in game performances of sitting volleyball athletes representing the different types of disabilities and (b) to assess whether the seated position vertical reach is one of the crucial factors in the game performance level of sitting volleyball athletes. One hundred male athletes from various national teams participating in the European Championships in Sitting Volleyball (2009) took part in this study. The athletes were categorized according to type of disability and the results of the vertical reach in a seated position. Thirtysix games were analyzed using the Game Performance Sheet for Sitting Volleyball. Twenty-three game performance parameters were studied. In addition, the sum and effectiveness of attacks, blocks, block services, services, ball receiving, and defensive actions were calculated. The main results indicated significant differences between athletes with minimal disability and athletes with single amputations from above the knee in the level of defensive performances and the summation of defensive actions. There was also a significant difference between athletes in relation to their vertical reach during activity and attacking actions, blocks, and ball receiving. In addition, there were strong relationships between the players’ vertical reach scores and their activity and effectiveness in sitting volleyball. In conclusion, the accuracy of the World Organization Volleyball for Disabled classification systems for sitting volleyball players was confirmed. There is a strong relationship between players’ vertical reach and their effectiveness in sitting volleyball.
