- Enhancing Mechanical Outcomes in Resistance Training: The Impact of Different Warm-Up and Re-Warm-Up StrategiesPublication . Neves, Pedro Miguel Pombo; Alves, Ana Sofia Ruivo; Marques, Diogo Luís Sequeira TorgalWarm-up in resistance training is essential to improve performance of practitioners. However, gaps remain in selecting the optimal warm-up protocol for resistance training. Alongside warm-up, re-warm-up is also an underexplored topic in this context. The present thesis seeks deepening understanding of how different warm-up and re-warmup strategies influence mechanical performance during resistance training. To achieve these objectives, five studies were conducted: i) a review about warm-up and re-warmup during resistance training; ii) interpretation and discussion of usual practices among strength coaches and practitioners in Portugal; iii) a comparison of two warm-up strategies (specific warm-up vs. general plus specific warm-up); iv) the effect of re-warmup on bench press and squat performance during resistance training; v) individual variability on response to the re-warm-up. The results showed that i) no prior studies have addressed re-warm-up’s effect on dynamic strength performance in resistancetrained individuals; ii) adherence to general and specific warm-up protocols was high (> 93 %), yet intra-session re-warm-up was seldom used (< 20 %); iii) no mechanical or psychophysiological differences emerged when combined general and specific warm-up or even specific warm-up were used during resistance training; iv) re-warm-up significantly enhanced mean propulsive velocity and power in the squat exercise, but not in the bench press exercise,; v) stronger, taller, and heavier athletes were reported to be more likely to respond positively to the re-warm-up protocol. Across these five developed studies, it was suggested that both specific warm-up and combined general and specific warm-up protocols can properly prepare athletes, once the selection of warm-up should consider the available time to perform the resistance training and the individuals’ purposes. The re-warm-up during resistance training, although little used, shows promise and appears to benefit stronger, taller, and with higher body mass individuals, further reinforcing the importance of personalized protocols.
- Students’ Attitudes and Motivational Climate in Physical Education: Implications for Engagement in Community Youth SportPublication . Pereira, Paulo Alberto da Silva; Marinho, Daniel AlmeidaThe physical activity carried out by students in Physical Education classes is insufficient to meet the recommendations recommended by the World Health Organization. Therefore, it is essential that young people practice extracurricular physical activities in their free time and persist in this practice after compulsory schooling, (i.e., when they no longer have the Physical Education subject). Hence, one of the objectives of this discipline must be to promote the acquisition of active lifestyles. Students' attitudes towards Physical Education and the motivational climate in Physical Education classes seem to be key variables in the reasons for practicing sports. However, there are few studies that have analyzed the relationship between these variables. In this sense, the purpose of this thesis is to analyze the relationships between students' attitudes towards Physical Education, their perception of the motivational climate in the subject's classes and their reasons for practicing sporting activities in extracurricular contexts. Findings showcase the following: (i) for the most part, students have a moderately positive attitude towards Physical Education; (ii) students’ positive attitudes towards Physical Education differ depending on their school year and gender; (iii) a more positive attitude towards Physical Education facilitates a better grade in this discipline; (iv) students perceive Physical Education classes more as mastery-oriented than performance-oriented; (v) school year and socioeconomic status seem to influence perceptions towards the motivational climate in Physical Education; (vi) perceiving the climate in Physical Education as masteryoriented and a positive attitude towards Physical Education are positive predictors of engaging in community youth sport programming; (vii) a mastery-oriented climate in Physical Education influences grades in Physical Education; (viii) the Portuguese versions of the SAtPE, EPCM and SMS II have appropriate psychometric properties in terms of reliability and validity and can enable scholars to assess the variables at stake in secondary schools within the Portuguese context. Taken together, these findings can pave the way for quality Physical Education programming and for conducting additional research within this line of inquiry.
