ABSTRACT
Currently, multiple strategies have been proposed to guarantee better processes of super compensation for sports training, however, there is still no consensus due to the emergence of new knowledge related to interference processes related to concurrent training programs and their impact on the definition of strategies for sports planning. The objective of this work was to evaluate the explosive strength variables and their relationship with aerobic capacity as a tool to define sports planning strategies. A descriptive correlational study was carried out that included the participation of 6 amateur runners, valued in their aerobic capacity and explosive strength through the 2-kilometer running test and the Squat Jump (SJ), Counter Movement Jump (CMJ) and horizontal feet jump together (SH) respectively. The highest correlation found was between aerobic capacity and SJ jump (p <0.001), which shows that aerobic capacity and muscular strength are fundamental pillars in training and athletic planning, in the same way, the non-existence of a relationship between the SH and the CMJ vertical jump (p = 0.121) allow establishing the practical importance of giving an emphasis to the development of aerobic capacity and specific strength in the horizontal running plane as an optimizing strategy that responds to sports performance in amateur runners.
Keywords: oxygen consumption; muscular strength; athletic performance.

RESUMO
Atualmente, foram propostas múltiplas estratégias para garantir melhores processos de sobre compensação na parte do treinamento esportivo, mas ainda não há consenso devido ao surgimento de novos conhecimentos relacionados com os processos de interferência relacionados com programas de treinamento simultâneos e seu impacto na definição de estratégias para o planejamento esportivo. O objectivo deste estudo foi avaliar as variáveis da força explosiva e a sua relação com a capacidade aeróbica como ferramenta para definir estratégias de planeamento desportivo. Foi realizado um estudo descritivo correlacional com a participação de seis corredores amadores, que foram avaliados quanto à sua capacidade aeróbica e resistência explosiva por meio do teste de corrida de 2 km e do Salto de Agachamento (SJ), Salto de Contramarcha (CMJ) e Salto Horizontal a Pés (SH), respetivamente. A maior correlação encontrada foi entre a capacidade aeróbica e o salto SJ (p<0,001), o que demonstra que a capacidade aeróbica e a força muscular são pilares fundamentais no treino e no planejamento atlético. Da mesma forma, a ausência de relação entre SH e CMJ salto vertical (p=0,121) permite estabelecer a importância prática de dar ênfase ao desenvolvimento da capacidade aeróbica e da força específica no plano de corrida horizontal como estratégia de otimização que responde ao desempenho desportivo dos corredores amadores.

INTRODUCTION
Sports planning has currently proposed concurrent training as a means of directly impacting variables linked to health and sports performance related to a high component of specificity that involves maintaining a sequenced, timed and specific structure according to the characteristics of endurance sports and their athletes (García-Manso., Arriaza-Ardiles., Valverde., Moya-Vergara., Mardones-Tare., 2017; Sánchez-López., & Rodríguez Pérez., 2017).
This type of program has been based on the fact that most sports specialties need to train both aerobic endurance and muscular strength in their different manifestations in order to improve sports performance and obtain greater effectiveness in the acquisition of beneficial adaptations compared to training both qualities separately (Flores-Zamora., 2019).
In this context, evidence has suggested that a high development of aerobic endurance seems to nullify the development and/or maintenance of muscle mass and strength due to the activation of the energy sensors of the protein kinase complex activated by AMP that favor mitochondrial adaptation and inhibit the activation of the markers of the mammalian target of rapamycin complex responsible for the activation of various anabolic processes induced by muscle strength exercises (Flores-Zamora A C, Rodríguez-Cedeño E M , Rodríguez-Blanco., 2017). Therefore, several strategies have been proposed in order to take advantage of the cumulative effect and guarantee a prolonged and stable adaptive phase linked to the different stimuli and physiological processes determining physical performance in endurance runners.
In this sense, multiple sports have postulated the development of sports performance optimization strategies based on separating the days dedicated to endurance training and the days dedicated to muscle strength training or, failing that, performing both types of training on the same day in a consecutive or separate manner with the aim of reducing the interference processes related to concurrent training programs. However, there is still no consensus on all these processes as a result of the heterogeneous results reported in various studies (Balsalobre-Fernández., Santos-Concejero., Grivas., 2016; Flores-Zamora., Rodríguez-Cedeño., Rodríguez-Blanco, 2017; Marcello, Greer, 2017; García-Manso et al., 2017; Alcaraz-Ibañez, Rodríguez-Pérez, 2018; Gómez-Molina, Ogueta-Alday, Camara, Stickley, García-López, 2018; Flores-Zamora, 2019).
For this reason, the purpose of this study was to evaluate the variables of explosive strength and its relationship with aerobic capacity as a tool for defining sports planning strategies.
MATERIAL AND METHODS
Design and participants
A descriptive correlational study was conducted consisting of six adult amateur runners of both sexes, assigned to a single group classified as physically active, regular weight, and with no diagnosed or reported morbid history.
Inclusion criteria
The sample was chosen under non-probability criteria for convenience, due to the low sample number available the following inclusion criteria were considered.
Procedure and instruments
This study was carried out in a single evaluation at the Mario Recordón athletic track in the Chilean National Stadium. The subjects were assigned to a single group, which was applied the international questionnaire for physical activity in its short version validated for Catalan population between 15 and 69 years (Román Viñas., Ribas Barba., Ngo., & Serra Majem, 2013), to this were added questions to investigate the history of cardiopulmonary diseases, musculoskeletal pathologies, acute or chronic systemic, in addition to information on the consumption of snuff and alcohol, therefore, participants were asked to avoid coffee consumption and present a fast of 2 hours and not exercise 24 h before the physical assessment.
Anthropometric assessment
The participants were measured and weighed to determine the body mass index and waist circumference of the participants according to the protocol of the World Health Organization (Labraña et al., 2017), using for these evaluations the anthropometric kit brand CESCORF composed of a Seca digital balance with pressure of 100 gr, Seca portable stadiometer 220 cm and a tape measure with pressure of 1 mm.
Standardized warm-up
The physical evaluation began with a ten-minute general warm-up consisting of joint mobility; flexions, extensions, abductions and adductions of the shoulders, hips, knees and ankles, as well as a continuous jog without intensity control.
Jump capacity evaluation
These three jumps were performed on three occasions each, the SJ and CMJ being evaluated by means of a DM JUMP by Prometheus contact platform connected to the DMJ v 2.2 software, while the SH was evaluated with a CESCORF tape measure (López López, Martínez Cubides, & Acosta Tova., 2019).
Aerobic capacity evaluation
It was determined with the 2 km run test at the highest possible speed (Laukkanen, Oja, Parkkari, & Manttari, 2002), recording the maximum heart rate achieved with the Polar® H10 pulse monitor and the VO2 peak with a Cosmed model K5 portable ergo spirometer, which was calibrated according to the manufacturer's recommendations.
Statistical analysis
Data were analyzed with SPSS 23.0 statistical software (SPSS 23.0 for Windows, SPSS Inc., IL, and USA). Data distribution was determined with the Shapiro-Wilk test. The Pearson correlation test was applied in order to relate the study variables considering an alpha level of 0.05 and a 95 % confidence interval. Finally, the variables studied were described with the following measures of central tendency and dispersion; mean, standard deviation, minimum, maximum, 25th percentile, 50th percentile and 75th percentile.
Ethical considerations
The research protocol was approved by the Ethics Committee of the Santo Tomas University's macro-zone center, folio 39.19, which considered this research to be risk-free in accordance with the ethical considerations stipulated in the Declaration of Helsinki of 2013.
RESULTS
The table 1 shows the descriptive statistics of the sample studied. Six adult runners aged 23 to 61 years, classified as physically active with normal weight (Body Mass Index <23.1) and without abdominal obesity (waist circumference less than 90 cm for men and 86 cm for women) participated. On the other hand, Vo2 peak shows a similar mean value, while SJ, CMJ and SH report lower values compared to athletes (Ortiz, Denadai., Stella., & De Mello., 2003; Centeno-Prada et al., 2015) (Table 1).

Years: period of 365 days, Kg/m2: kilograms per square metre, cm: centimetres, ml/kg/min: millilitre of oxygen used per kilogram of body weight in one minute.
In table 2, the results are shown in relation to the VO2 peak as an indicator of aerobic capacity and the SJ, CMJ and SH jumps as indicators of jumping capacity. VO2 peak correlates significantly with all indicators. On the other hand, the vertical jump capacity in SJ shows a significant positive relationship with CMJ and SH as an indicator of horizontal jump, while the horizontal jump capacity showed no relationship with CMJ as an indicator of vertical jump (Table 2).

DISCUSSION
The results shown in table 1 are similar to the VO2 values established for endurance athletes, while the values in jumping capacity and elasticity index are lower than the expected values for a similar population of young adults and athletic practitioners (Ortiz, Denadai., Stella., & De Mello., 2003; Centeno-Prada et al., 2015). These results can be explained based on the available scientific evidence, around the practice of activity and/or physical exercise of an aerobic type, practiced regularly around 150 minutes per week, is associated to positive adaptations on body composition and physical condition, since can generate a negative energy balance by inducing weight loss due to changes in insulin sensitivity, immune response, endogenous antioxidant systems and AMP-activated protein kinase, while endurance or muscle strength exercises have been associated with a synergistic effect in terms of improvements in aerobic capacity (Spinoza-Salines, et al., 2020).
As for the VO2 behavior, it reflects a good development of the aerobic capacity as a result of a training focused on this quality, while the lower values in the jumping capacity can be explained in part by the lack of hypotrophy characteristic of endurance runners. In this sense, it is known that aerobic work can cushion the development of hypertrophy by inducing lower levels of capacity to generate muscular strength and consequently higher levels of peripheral fatigue and decreases in running economy (Balsalobre-Fernández et al., 2016; García-Manso et al., 2017; Marcello et al., 2017; Alcaraz-Ibáñez et al., 2018; Gómez-Molina et al., 2018; Flores-Zamora et al., 2017; Flores-Zamora., 2019).
On the other hand, the results reported between aerobic performance and both vertical and horizontal jumps are consistent considering that VO2 peak can be attributed to any activity in which there is a certain level of physical demand (Cade et al., 2018).
The higher ratio of Squat Jump to VO2 peak can be attributed to the fact that the SJ has a high muscle strength component, and it is therefore, considered a good indicator for both sports' performance and the level of neuromuscular fatigue caused by repeated high intensity exertion. In this regard, the literature has reported that a high level of strength expressed in SJ does not always guarantee better overall performance; This is due to the fact that specific training programs focused on strength development are the ones that bring improvements related to indicators such as race economy, peak VO2, recruitment capacity, synchronization of motor units and intra- and inter-muscular coordination, but not the strength level as such, while the low relationship between CMJ and SH can be justified by the influence of spatial-temporal parameters and the different neuromuscular adaptations linked to horizontal movements with slope or vertical movements generated by the race motor pattern (Ogueta-Alday., García-López., 2016).
Another possible explanation for the low relationship between CMJ and SH can be attributed to the little familiarity of those evaluated with performing both horizontal and vertical jumps. In this respect, the motor action involved in the jumps implies a predominance of a guiding quality that involves the technical characteristics of the movement, therefore, an adaptive integral reaction of the organism responds mainly to specific adaptations to the sporting gesture and not to the development of certain physical qualities, so that performance in medium and long distance races is determined by an overall motor capacity subordinated to muscular strength, due to which physical qualities do not usually appear in an abstract form but in combination with physical factors conditioning performance (Flores-Zamora., 2019).
Following this line of argument, Centeno-Prada et al., (2015) postulate that the relationship between both types of jumps is directly influenced by the capacity and efficiency in the utilization of the viscoelastic components of the muscle-tendon system, since it is known that these can generate and store energy, which when used efficiently can improve jumping performance, In this context, the jumping capacity of CMJ like SH will depend not only on factors such as muscular strength expressed in the number of fast fibers and the capacity of recruitment of these, but also the coordination capacity reflected in the use of the muscular elastic reflex (González-Badillo, Jiménez-Reyes, Ramírez-Lechuga, 2017).
On the other hand, it has been observed that the intensity of the load is another fundamental factor related to the modulation of diverse adaptations linked to both muscular strength and aerobic capacity. In this respect, the evidence indicates in a global way that a plyometric strength program at a high intensity can affect the economy of running at moderate running intensities, so that no better long-term performance can be guaranteed, while a low intensity programme has demonstrated a high effect on physical performance based on improving running economy, peak speed and neuromuscular characteristics (Flower-Bloss., 2019).
In this context, the importance of concurrent training in the practice of aerobic endurance sports lies in the need to implement a well-planned and periodised training programme that considers the processes of interference between physical qualities with the aim of taking advantage of the cumulative effect and guaranteeing a prolonged and stable adaptive phase linked to the different stimuli and physiological processes that determine physical performance in endurance runners (Balsalobre-Fernández, Santos-Concejero, Grivas, 2016; Vorup et al., 2016; Flores-Zamora, Rodríguez-Cedeño, Rodríguez-Blanco, 2017; Marcello, Greer, 2017 García-Manso et al., 2017; Alcaraz-Ibáñez, Rodríguez-Pérez, 2018; Gómez-Molina, Ogueta-Alday, Camara, Stickley, García-López, 2018; Flores-Zamora, 2019).
Limitations of the study
This research is mainly limited in its external validity, since the selection of the sample was made for convenience, using a small sample. Likewise, these findings may be influenced by the wide age range and the non-separation of the sample by sex or age groups. On the other hand, some data such as smoking, alcohol consumption and disease history were obtained through self-reporting, which could lead to a risk of bias due to overestimation of unhealthy styles.
The findings reported in this population are indicative of a significant positive relationship between aerobic and jumping capacity. Thus, the practical importance of a training strategy that encompasses the development of aerobic and jumping capacity in parallel can be concluded by considering all interference processes related to concurrent training and athletic performance in amateur endurance runners.
