(1) Background: The objective of this research was to analyse the most demanding passages (MDP) considering the sprint variable relative to the maximum level of sprint ability of each player as a function of player position, final outcome and part of the match during the competitive phase of a professional soccer season. (2) Methods: Global positioning system (GPS) data were collected from 22 players according to their playing position in the last 19 match days of the Spanish La Liga professional soccer in the 2020/2021 season. MDP were calculated from 80% of the maximum sprint speed of each player. (3) Results: Wide midfielders covered the greatest distance at >80% of the maximum speed (2.4 ± 1.63 seg) and the longest duration (21.91 ± 13.35 m) in their MDP. When the whole team was losing, it demonstrated greater distances (20.23 ± 13.04 m) and longer durations (2.24 ± 1.58 seg) compared to games in which it was winning. When the team ended up drawing, the relative sprint distance covered in the second half was significantly greater than in the first (16.12 ± 21.02; SD = 0.26 ± 0.28 (−0.03/−0.54). (4) Conclusions: Different demands of MDP, according to the sprint variable relative to the maximum individual capacity in competition, are required when contextual game factors are considered.

PurposeCelebrity endorsement is a preferred marketing communication strategy adopted by business firms. The present study suggests theoretical underpinnings for investigating the effect of celebrity endorsement on individual investors' intentions to invest in the shares of companies. The study integrates marketing communication and behavioural finance theories to understand investor behaviour in the stock market.Design/methodology/approachThe study used a questionnaire based on a conjoint analysis technique. The retail investors from India filled out the questionnaire. The authors developed an orthogonal design to generate retail investors' investment intentions and applied the full-profile conjoint method.FindingsThe results reveal that investors prefer to invest in technology-related firms when they employ entertainment celebrities to endorse their products. Investors prefer that entertainment celebrities' personalities match the single brand only they are endorsing. Further, investors choose to invest during corrective market trends in emerging economies, such as India.Originality/valueThe study offers practical implications for corporate entities and marketing professionals by analysing retail investors' investment intentions in financial markets.

This paper focused on the interior boom noise of a mini-car when driving at high speeds. Vehicle interior noise rotor drum tests in semi-anechoic room showed that vehicle interior boom noise in narrow frequency band exited near 250Hz. Structural and acoustic finite element analysis certified the front roof and rear floor coupled with interior acoustic cavity around this frequency, causing acoustic cavity resonance. On the base of sensitivity analysis technology, a structural improvement schemes pasting free damping fin on the front roof and rear floor of mini-car body for vibration and noise reduction was proposed. Finite element Modal analysis of the mini-car body after improving indicated that local modal amplitude of the mini-car body at the front roof and rear floor around 250Hz was controlled effectively. Mini-car rotating drum test results after improving showed that vehicle interior boom noise was decreased obviously after pasting free damping fin at the front roof and rear floor. The improving schemes and noise reduction effects proposed in this paper were validated.
