Due to the complexity of automobile manufacturing process, some flexible and delicate assembly work relies on manual operations. However, high-frequency high-load repetitive operations make workers prone physical fatigue. This study proposes a method for evaluating human fatigue automobiles with methods: NIOSH (National Institute Occupational Safety Health), OWAS (Ovako Working Posture Analysis System) RULA (Rapid Upper Limb Assessment). The cerebral oxygenation signal is selected as an objective physiological index reflecting level verify proposed evaluation method. Taking auto seat example, 18 group experiments were carried out ARE platform (Augmented Reality-based Ergonomic Platform). Furthermore, predictions metabolic energy expenditure performed in Tecnomatix Jack. Finally, it concluded that can reflect more accurate than consumption Jack because immersion comes AR devices precision motion capture devices.

Performance analysis in sports is a rapidly evolving field, where academics and applied performance analysts work together to improve coaches' decision making through the use of indicators (PIs). This study aimed provide comprehensive factors affecting running (RP) soccer teams, focusing on low (LI), medium (MI), high-speed distances (HI) number runs (NHI). Data were collected from 185 matches Turkish first division's 2021-2022 season using InStat Fitness's optical tracking technology. Four linear mixed-model analyses conducted RP metrics with fixed factors, including location, team quality, opponent ball possession, high-press, counterattacks, central defenders, forwards. The findings indicate that high-press quality affect MI (d = 0.311, d 0.214) HI 0.303, 0.207); influences 0.632); location counterattacks impact 0.228, 0.450); defenders affects NHI 0.404, 0.319); possession LI 0.287). forwards did not influence any metrics. provides valuable insights into influencing soccer, highlighting complex interactions between formations physical, technical-tactical, contextual variables. Understanding these dynamics can help coaches optimize strategic making.

Background Understanding the epidemiology of soccer injuries during specific international competitions is essential for customizing preventive strategies. Several studies have reported outcomes related to but, best our knowledge, there has been no investigation into injury patterns any African Cup Nations (AFCON) tournaments. This study aimed analyse incidence and characteristics 2021 (AFCON), which took place in Cameroon from January 9 February 6, 2022. Methods A video-based analysis covering 52 matches was conducted by two independent consultant physicians. They reviewed replays determine ( i.e. ; mechanisms, body location, match moment, player substitution, absence next match, referee decisions). Results The tournament involved 519 male players, comprising 275 (ALP) 244 Non-African (NALP) league players. Eighty-seven occurred, with incidences 1.7 48.8 per 1000 hours, respectively. Injury rose competition stages, particularly contact mechanism injuries. Non-contact (23/87) predominantly occurred after 60 minutes play (19/23), thigh being most frequently affected part (18/87). Older age playing time significantly correlated occurrence (p=0.032 p<0.001, respectively). NALP midfielders forwards were notably injured mechanisms (36/45) attacking zone. Although non-contact more common ALP than (13/42 vs. 9/45), difference lacked statistical significance (p=0.240), a higher rate muscle 10/45, p=0.001).

Tyrosine has been proposed to potentially provide ergogenic benefits cognitive and physical performance in physiologically demanding environments. However research into its effectiveness on during exercise the heat revealed mixed findings. This study examined effects of a commonly employed dosage tyrosine supplementation soccer players' decision-making performance, appraisal, affective states, prolonged high-intensity intermittent hot conditions. Eight trained male players completed 92-minute cycling sprint protocol whilst responding soccer-specific tasks at various time points 32°C (50%rh), two counterbalanced conditions; (150mg.kg-1) placebo.

Fatigue in team sports has been widely researched, with a number of systematic reviews summarising the acute (i.e., within 48-hours) response outdoor sports. However, fatigue to indoor court-based is likely differ due smaller playing fields, harder surfaces, and greater match frequencies, thus should be considered separately Therefore, this study aimed conduct review on team-sport, identify methods markers used measure fatigue, describe responses. A search electronic databases (PubMed, SPORTDiscus, MEDLINE CINHAL) was conducted from earliest record June 2023. Included studies investigated either physical, technical, perceptual, or physiological taken before after training, match, tournament play. One-hundred eight were included, measuring 142 fatigue. Large variability methods, timeline measurements present. Cortisol (n = 43), creatine kinase 28), countermovement jump 26) testosterone 23) most frequently examined markers. Creatine displayed consistent trend, increasing 10–204% at 24-hours across There large determine responses Future researchers focus that display high reliability transfer practice. The robustness may increased by ensuring appropriate timescale marker measurement are used. Further research required which combination best describes response.

Objective: Soccer requires athletes to possess strength and physical endurance, involving running, jumping, occasionally, injury. Injuries stimulate the body's synthesis of anti-inflammatory cytokines, including interleukin-6 creatine kinase, which can influence an athlete's performance. Elevated concentrations kinase impair metabolic system. To avert this, interventions such as cold water immersion are frequently employed. This study seeks evaluate impact on levels, facilitating recovery post-soccer match in female athletes. Theoretical Framework: is based physiological theory, emphasizes role therapy reducing muscle inflammation, fatigue, oxidative stress. It also incorporates molecular response framework, highlighting how Cold Water Immersion (CWI) influences biochemical markers related recovery. By combining these perspectives, research provides a comprehensive understanding CWI’s effects both performance cellular adaptation soccer players.
