Relationship Between Indicators of Training Load in Soccer Players

Abstract

This study examined the relationship between work load indicators used to quantify full training sessions in soccer. The participants were 28 semiprofessional male soccer players age 22.9 ± 4.2 years, height 177 ± 5 cm, body mass 73.6 ± 4.4 kg. Players' physical and physiological work load was monitored over 44 training sessions using global positioning system devices (10 Hz) and heart rate, respectively. After each training session, players' training perceived-exertion (rating of perceived exertion [RPE]) was assessed using the Borg CR-10 scale. Players' internal training load was assessed using the session-RPE and the Edwards methods. Total distance, distances covered at arbitrary selected high-intensity speed zones (≥18 and 21 km·h(-1)), bout frequency at speed >18 and 21 km·h(-1), and work:rest ratio during training drills were considered as signs of physical work load. Furthermore, player load assumed as reflection of total center-of-mass acceleration was considered as representative of players' external load. Very-large association of player load with Edwards and session-RPE methods was found. Total distance covered was large to very large associated with Player Load, Session-RPE, and Edwards methods. The findings of this study provided evidence for the safe use of session-RPE, Edwards methods, and Players Load as valid indicators of training responses in soccer.

Establishing a duration standard for the calculation of session rating of perceived exertion in NCAA division I men’s soccer

“…Similar to the results of the present study, Scott et al 8 reported session RPE to be highly correlated with total distance (r = 0.80), Player load (r = 0.84), and HODO (r = 0.65) in professional soccer players. In addition, Casamichana et al 3 examined the relationship between session RPE and total distance (r = 0.76) and Player load (r = 0.74). It appears that total distance, HODO, and Player load may be viable indicators of training load in NCAA Division I soccer players.…”

“…However, few studies have observed the relationship between session RPE and external loads measured using GPS technology. 3,8 These studies have reported significant correlations between session RPE and both GPS and accelerometer derived variables (r = 0.71-0.84; P < 0.01).…”

“…Much of the evidence regarding the validity of session RPE as a tool to monitor soccer performance has been provided via relationships with summated heart rate scores as criterion measures. [3][4][5] Although there is a large aerobic component to soccer 6 , heart rate in itself may not be the most meaningful indicator of training load for such an intermittent-type sport 7 . Thus, additional methods may be required to assess session RPE as a global estimate of training load during soccer training.…”

“…11 Accordingly, the balance between training stress, competition and recovery is of significant importance so as to protect against underperformance 12 and increased injury risk 13 . Recent research in soccer and rugby has quantified aspects of weekly 14,15 , monthly 8,16,17 and seasonal 5 TL.…”

“…En esta línea, el estudio de en qué medida las tareas de entrenamiento (Casamichana et al, 2012), y de manera específica, los juegos reducidos se asemejan a la competición (Casamichana y Castellano, 2015) puede servir de gran ayuda para que los entrenadores puedan adecuar los contenidos de entrenamiento a sus propósitos. Con intención de provocar un incremento o reducción de las demandas técnicas, físicas y fisiológicas de su práctica, los entrenadores de baloncesto pueden manipular las variables de los diferentes juegos en espacios reducidos (Klusemann, Pyne, Foster, y Drinkwater, 2012).…”
