「忙」的語意特徵及認知概念──以語料庫語言學及語意側重為架構之研究

<p>本文基於「COCT 書面語語料庫2017」對「忙」的語意特徵及認知概念進行分析。先以單字詞「忙」為單位，分析其語意特徵；再分析「忙得」後方的補語結構，研究「忙」的認知概念。本研究結果顯示「忙」的語意特徵有三類：投注大量心力和時間做某事、在有限的時間抓緊時間做事、表密集繁多，而各類能以不同的語意側重（profile）呈現。「忙」的認知概念類別為：事件狀態、生理表現、情緒。綜合上述兩個類別系統，能發現「忙」的意義具有三個特性：急迫性、消耗性、密集性。</p> <p>&nbsp;</p><p>This study utilized the written data from the &quot;2017 Corpus of Contemporary Taiwanese Mandarin&quot; to analyze the semantic features and cognitive concepts of m&aacute;ng &quot;busy&quot;. There were a total of 1,094 instances analyzed, after removing the meanings bāngm&aacute;ng &quot;help&quot;, and other four-character idioms. For analysis, the study firstly analyzed the semantic features of m&aacute;ng and its different semantic profiles. The results showed that the semantic features of m&aacute;ng can be sorted into three types: (1) to describe someone taking a great effort and time to do something; (2) to describe someone seizing the time to finish something urgently; and (3) a dense condition given a specific period of time. M&aacute;ng can be profiled according to these semantic features. Next, the complements following m&aacute;ng were analyzed for the cognitive concepts of m&aacute;ng. Three categories of cognitive concepts of m&aacute;ng were identified: the state of events, physical performances, and emotions. Together, the semantic features and the cognitive concepts of m&aacute;ng display its urgency, consumptiveness, and density. This study provides a detailed account of a frequently used word in Mandarin, a word so frequently used that we do not normally realize its different profiling of meanings.</p> <p>&nbsp;</p>

Additional players and half-court areas enhance group tactical-technical behavior and decrease physical and physiological responses in basketball small-sided games

Small-sided games are used to improve tactical-technical and physical performances in team sports. This study compared the physical, physiological, and tactical-technical responses during 3 versus 3 basketball small-sided games performed in full and half-court: numerical equality (3 vs. 3), numerical superiority (4 vs. 3), and with a non-scorer floater (3 vs. 3 + 1). A total of 45 U-14 and U-15 male athletes participated in the study. They were divided into three-player teams and played one 4-minute bout of each small-sided game type. Heart rate and the time spent in four acceleration zones (0.0–0.5, 0.5–1.0, 1.0–1.5, and 1.5–2.0 g) were recorded using heart rate monitors and triaxial accelerometers. Small-sided games were filmed for the analysis of tactical-technical behavior. Results showed a higher frequency of space creation without the ball, and a mean number of passes per offense in the formats 4 versus 3 and 3 versus 3 + 1, and a lower frequency of space creation with the ball dribbled in 3 versus 3 + 1 compared with 3 versus 3. Physical and physiological responses were higher in the full-court regardless of format and in numerical equality regardless of court area; only the time spent in the highest acceleration zone was higher in half-court small-sided games. We concluded that additional players increase group tactical actions and decrease physical and physiological responses in 3 versus 3 basketball small-sided games.

The Effect of the COVID-19 Lockdown on the Position-Specific Match Running Performance of Professional Football Players; Preliminary Observational Study

The COVID-19 pandemic interrupted professional football in the 2019/2020 season, and football experts anticipate that the consequences of lockdown measures will negatively affect the physical performance of players once competition restarts. This study aimed to evaluate position-specific match running performance (MRP) to determine the effect of COVID-19 lockdowns on the physical performance of professional football players. Players’ MRPs (n = 124) were observed in matches before and after the COVID-19 lockdown in the 2019/2020 season of the highest level of national competition in Croatia and were classified according to player position: central defenders (CD; n = 42), fullbacks (FB; n = 20), midfielders (MF; n = 46), and forwards (FW; n = 16). The MRPs were measured using Global Positioning System, and included the total distance covered, low-intensity running (≤14.3 km/h), running (14.4–19.7 km/h), high-intensity running (≥19.8 km/h), total accelerations (>0.5 m/s2), high-intensity accelerations (>3 m/s2), total decelerations (less than –0.5 m/s2), and high-intensity decelerations (less than –3 m/s2). The results indicated that, in matches after the COVID-19 lockdown, (i) CDs and FBs featured lower running and high-intensity running (t-value: from 2.05 to 3.51; all p < 0.05; moderate to large effect sizes), (ii) MFs covered a greater distance in low-intensity running and achieved a lower number of total accelerations, and total and high-intensity decelerations (t-value: from –3.54 to 2.46; all p < 0.05, moderate to large effect sizes), and (iii) FWs featured lower high-intensity running (t-value = 2.66, p = 0.02, large effect size). These findings demonstrate that the physical performances of football players from the Croatian first division significantly decreased in matches after the COVID-19 lockdown. A combination of inadequate adaptation to football-specific match demands and a crowded schedule after the competition was restarted most likely resulted in such an effect.

An Analysis of Acceleration and Speed Performances Through the Positions in Handball

This research was conducted in order to compare the acceleration and speed performances of handball players according to their positions. A total of 60 male handball players that includes 5 goalkeepers, 15 middle playmakers, 7 right playmakers, 8 left playmakers, 7 right wingers, 8 left wingers and 10 pivots who actively play handball in the 2nd league of the Turkish handball federation has participated in the study voluntarily. Average age of the subjects participating in the study is determined as 19.5±1.43 for the goalkeepers, 19.3±1.35 for the right-left playmakers, 18.7±1.29 for the right-left wingers, 19.1±1.89 for the pivot players. Acceleration and speed performances of the subjects were measured in accordance with the measurement technique and all the data obtained were analyzed in the SPSS 20.0 software package program. Results that is obtained is examined, it is seen that the best values in terms of acceleration and speed performance were the performance values of right-left playmakers and right-left wing players, while the worst performance values belonged to pivot players. As a result of our study, it was observed that athletes have different physical performances in handball according to their playing positions.

The effect of 6-week core stability training on core endurance and physical performance in professional rugby players: A randomized controlled pilot study

Background: Core stability training (CST) is used to enhance sports performance. The relationship between core endurance and physical performance in rugby players had not been evaluated before in Asia. Aims and Objectives: This study aims to determine the effects of a 6-week specific CST program on the core endurance and physical performances (speed, upper body power, lower body power, and agility) following a CST intervention in male rugby players. Materials and Methods: Professional rugby players (n=8, intervention and n=8, control) were randomly selected. Mean (SD) age, height and weight of intervention group were 25.25 (2.4) years, 1.64 (0.03) m, and 69.6 (14.9) kg, respectively. In the control group, corresponding values were 29.75 (4) years, 1.66 (0.04) m, and 72.3 (19.1) kg, respectively. Intervention group was trained CST sessions complementary to the usual physical training, 3 times/week for 6 weeks. The control group followed the usual physical training. Subjects were tested for four physical performances (using 40 m sprint, vertical jump, 3 kg medicine ball put, and agility T tests) and four core endurance tests (back extension, abdominal fatigue [AF], and left and right bridges). Results: AF, left bridge, right bridge, and total core endurance were significantly increased in the intervention group (P=0.028, P=0.006, P= 0.008, and P=0.001, respectively). Agility and AF were increased significantly in the control group (P=0.048, P=0.027). The right side bridge endurance (P=0.024) was significantly increased in the intervention group compared to the control group. Conclusion: The results suggest that the CST improves core endurance without improving physical performances in rugby players.

Effects of Three Preseason Training Programs on Speed, Change-of-Direction, and Endurance in Recreationally Trained Soccer Players

Background: Modern coaches experience a drastic reduction of the available training time with an increasingly large number of competitions during the competitive season. Thus, they must choose wisely the most efficient methods to improve the physical fitness of their players during the preseason. Among all the methods, this study compared the effects of plyometric training (PT), sprint interval training (SIT), and small-sided games (SSGs) on the performance of recreationally trained soccer players.Methods: Seventy-three participants were randomly assigned in one of the three experimental groups (i.e., PT [n = 23], SIT [n = 26] or SSGs [n = 24]) and completed two sessions per week for a total of 3 weeks. Meanwhile, the whole group maintained their habitual soccer-specific training program who do not interfere in the preparation of the season. Repeated sprint ability (RSA), maximal aerobic speed (MAS), and a 30-m sprint were assessed at baseline (PRE) and post-training (POST).Results: Performance in SSGs decreased for the average speed from 0 to 10 m (V0−10m; −0.84 km h−1, −4 ± 5%, p &lt; 0.001), the maximal distance (Dmax) covered in the 30-s RSA test (−3.65 m, −3 ± 6%, p &lt; 0.01) and MAS (−0.52 km h−1, −3 ± 6%, p &lt; 0.01). PT increased the mean distance (Dmean) covered in the 30-s RSA test (+5.98 m, 5 ± 4%, p &lt; 0.001) and MAS (+0.58 km h−1, 7 ± 5%, p &lt; 0.01) while an improvement of all parameters but the maximal sprint speed reached during the 30-m trip (Vmax) was found in the SIT group (V0−10m: +1.462 km h−1, 8 ± 5%, p &lt; 0.001; Dmax: +7.89 m, 6 ± 5%, p &lt; 0.001; Dmean: +8.69 m, 7 ± 5%, p &lt; 0.001 and MAS: +1.74 km h−1, 12 ± 8%, p &lt; 0.001). All SSG POST values were significantly lower than PT and SIT (p &lt; 0.01). Dmean and MAS in POST were also significantly higher in SIT than in the PT group (p &lt; 0.001).Conclusion: This study suggests that both PT and SIT could be a better alternative to SSGs to boost performances during preseason. Moreover, SIT seems to produce higher improvements in physical performances than PT.

Bayesian Estimation of the Variation in Strength and Aerobic Physical Performances in Young Eumenorrheic Female College Students during a Menstrual Cycle

Background: The purpose of the present investigation was to examine changes in strength and aerobic physical performances in young eumenorrheic female college students during the menstruation phase and different testing occasions within a menstrual cycle. Methods: A repeated measure experimental design used to investigate the variation in physical performance from different testing occasions compared to the menstruation phase. Twelve eumenorrhea female college students volunteered to participate in this study. The participants were 19.8 ± 0.8 (±SD) years old, with the body mass of 61.4 ± 11.6 kg, the height of 162.6 ± 5.1 cm, and BMI of 23.2 ± 3.8. All participants reported regular monthly menstrual cycles of 26–33 days, none of whom reported taking oral contraceptives in their entire life. None of the participants was an athlete, and their level of activity was limited to physical education classes and recreational activities. The menstrual cycles during the two cycles before testing had to be between 26 and 35 days to participate in this study. Second, there had to be no current or ongoing neuromuscular diseases or musculoskeletal injuries. Third, no one should be taking any dietary or performance-enhancing supplements that could have affected testing results during this study. The participants tested on one-repetition maximum (1RM) bench press, 1RM leg press, push-up to failure, leg press with 60% of 1RM to failure, and running 1600 m time trial. The participants were tested on four occasions based on the classical model of the menstrual cycle (i.e., 28 days; early follicular phase (menstruation phase) on day 2 (T1), late follicular phase on day 8 (T2), ovulation phase on day 14 (T3), and mid-luteal phase on day 21 (T4)). Data were analyzed using the Bayesian hierarchical model (Bayesian Estimation) with Markov Chain Monte Carlo simulation using the decision-theoretic properties of the high-density interval (HDI) + ROPE decision rule. Results: The Bayesian estimated difference from the four testing occasions neither showed that the most credible parameter values (95% HDI) were sufficiently away from the null value nor showed that the most credible parameter values are close to the null value (Rope odds ratio among all tests were spread in 12.7% < 0 < 87.3% with an effect size ranging between d = −0.01 and 0.44). Hence, no decision can be made as to whether strength and aerobic physical performances change during the menstruation phase compared to the other testing occasions within a menstrual cycle. Conclusions: It was noticed that different studies concluded different results, which make the research in menstrual cycle difficult. However, the results from this study and published studies suggest that future research should investigate and profile motivation and autonomic nervous system activity during the menstruation phase and examine the interaction effect of the three on performance compared to other testing occasions within a menstrual cycle.
