It has been observed how self-compassion improves adaptive coping, well-being and reduces anxiety in situations of stress. The present study tried to see if there were significant differences in the level of self-compassion in high-performance athletes with or without injury at different times of the season. With a sample composed of 79 athletes from different disciplines, it was carried out through the Scale of Self-compassion SCS in Spanish, summarized from 12 articles (García-Campayo, Navarro, Andrés, Mortero, López and Piva, 2014). The results collected in this research were not conclusive or significant, so it would be advisable for future studies with a larger sample, in contexts of sports injury and with a psychological intervention of the environment.

This study aims to determine if the Humon Hex device used to measure SmO2 can be used as an equivalent to the lactate test. Studying whether the potency of the lactate threshold can be established by changes in SmO2. The objective is to compare the blood lactate concentration and the SmO2 measurement to predict the lactate threshold power during the performance of a progressive exercise test in trained cyclists. During the power increases, it is observed that the% SmO2 decreases, and the Lactate concentration increases. Through Pearson's correlation analysis, a strong inverse correlation is evidenced between the variables studied. It is observed that SmO2, both at the basal level and at the lactate threshold, presents a wide dispersion of its values that limits its usefulness, and we were unable to find a standard absolute threshold value for all the subjects in the sample. Comparing the threshold lactate power estimated by the lactate concentration in the blood, and the algorithm of the Humon Hex software gives an average difference of 13w ± 18.5, and an average time difference of 87´´ ± 27.5. Although the n of the sample is low, this data is promising to apply the Humon Hex as an indirect estimation tool of the lactate threshold of daily training.

The monitoring of loads is investigated to diagnose the recovery and optimisation of athletes. The aim was to show the evolution of the loads of field players in different microstructures (ME) by observing how environmental fluctuations influence the development and execution of these, and to provide reliable and valid low-cost monitoring tools. 23 participants aged 22±3 years from the 1st Catalan Regional Division (Group A) were observed during the 2018-2019 season. The five types of ME were chosen. Microsoft Excel software was used to record the information and determine the external and internal load, injury risk and define recovery and optimisation times. The results show an Average Specificity of a targeted-special character together with a lower Load Balance in the Maintenance Microcycle (MM): 0.32p; and in the Competitive Microcycle (CM) with physical-technical-tactical balance: 0.86p. Preparatory Microcycle (PM) obtained a Monotony Index (MI) of 6.54p; the Targeted Transformation Microcycle (MTD) of 8.55p and Special Transformation Microcycle (STM) of 5.89p. The highest relative fatigue percentage (%FR) was 85% for MTD and 32% for MC. The highest RPE was for MC = 8.88p; MTD = 8.04p and MTE = 7.02p. Sleep quality and stress were high in the MC and muscle damage and cumulative fatigue in the MP and MTD. Recovery is reflected in all ME after 48h in the CMJ. These calculations are accepted as effective tools to indicate the evolution of load dynamics as long as they can be contextualised.

The aim of this study was to find out the resistance training influence on the child and adolescent population, as well as determine the possible risks or benefits that the training of this physical capacity may cause. A systematic review has been carried out on the impact of resistance training in subjects aged between 6 and 18 years. The studies used in this review were identified through Pubmed database, selecting those written in English or Spanish, from 2010 to the present. The revision was carried out between November 2020 and May 2021. A total of 328 articles were identified in the initial search, of which 20 articles were chosen for this systematic review. The results show that the benefits from resistance training clearly outweight their risks, as long as the training program is supervised and guided by qualified personnel, individualizing the training loads to each subject need. Likewise, resistance training in young population contributes to the improvement of different motor skills and sports activities, resulting in an effective strategy for diseases such as obesity.

The aim of this research is to define the intensity, frequency, and duration of physical activity that respondents engage in to determine possible effects on overall health in the medium and long term. For this purpose, a quantitative approach research, non-experimental and cross-sectional design is carried out. With a mixed sample (probabilistic and non-probabilistic), composed of n=303participants, over 18 years old, selected by convenience. The instrument used is the “International Physical Activity Questionnaire” (IPAC), a short version consisting of 7 questions, preceded by 3 questions on the socio-demographic composition of the participants. Among the main results, 74.9 per cent of the respondents were teachers and16.8 per cent were administrative; 35 per cent had not engaged in intense or moderate physical activity; and 83.9 per cent had sat for 4 to more than 10 hours a day (24.1 per cent between 4 and 6 hours; 22.8 percent between 7 and 8 hours; 19.5 per cent between 9 and 10 hours; and 17.5 per cent for more than 10 hours). In conclusion, a probable relationship could be established between confinement and decreased physical activity; and between confinement and the number of hours that respondents have been seated. In addition, some medium- and long-term effects on the overall health of the participants (and all those who fit the characteristics of the study) could be assumed from physical inactivity and prolonged sitting time.
