Activity profile and physiological response to football training for untrained males and females, elderly and youngsters: influence of the number of players

Abstract

The present study examined the activity profile, heart rate and metabolic response of small-sided football games for untrained males (UM, n=26) and females (UF, n=21) and investigated the influence of the number of players (UM: 1v1, 3v3, 7v7; UF: 2v2, 4v4 and 7v7). Moreover, heart rate response to small-sided games was studied for children aged 9 and 12 years (C9+C12, n=75), as well as homeless (HM, n=15), middle-aged (MM, n=9) and elderly (EM, n=11) men. During 7v7, muscle glycogen decreased more for UM than UF (28 +/- 6 vs 11 +/- 5%; P<0.05) and lactate increased more (18.4 +/- 3.6 vs 10.8 +/- 2.1 mmol kg(-1) d.w.; P<0.05). For UM, glycogen decreased in all fiber types and blood lactate, glucose and plasma FFA was elevated (P<0.05). The mean heart rate (HR(mean)) and time >90% of HR(max) ranged from 147 +/- 4 (EM) to 162 +/- 2 (UM) b.p.m. and 10.8 +/- 1.5 (UF) to 47.8 +/- 5.8% (EM). Time >90% of HR(max) (UM: 16-17%; UF: 8-13%) and time spent with high speed running (4.1-5.1%) was similar for training with 2-14 players, but more high-intensity runs were performed with few players (UM 1v1: 140 +/- 17; UM 7v7: 97 +/- 5; P<0.05): Small-sided games were shown to elucidate high heart rates for all player groups, independently of age, sex, social background and number of players, and a high number of intense actions both for men and women. Thus, small-sided football games appear to have the potential to create physiological adaptations and improve performance with regular training for a variety of study groups.

Injury prevention in male veteran football players – a randomised controlled trial using “FIFA 11+”

“…German veteran footballers are restricted to a certain minimum age typically, 30 or 32 years dependent upon the local federation. Recent studies have shown that recreational football can improve metabolic, cardiovascular and musculoskeletal parameters and can therefore be an effective tool to protect against certain lifestyle diseases (Krustrup, Aagaard, et al, 2010;Krustrup, Christensen, et al, 2010;Randers et al, 2010). However, playing also involves the risk of injuries Faude, Junge, Kindermann, & Dvorak, 2006;Junge & Dvorak, 2004;Peterson, Junge, Chomiak, Graf-Baumann, & Dvorak, 2000).…”

Assessment of periodization training in soccer

“…This would explain the increase of oxidative capacity measured in type II fibers observed in the past study of many authors; intermittent drills can result in increased glycolytic characteristics and ability to perform maximum efforts (Randers, et al 2010, Rebelo, et al, 2012). This study is based on the method of Periodization Training that refers to two important aspects: Periodization of the Season Plan, which allows players to split and manage the training program and to achieve maximum fitness for the most important games, Periodization of Motor-Conditional Skills which allows players to lead to an optimal level of conditional skills, such as strength, speed and endurance.…”

Demandas físicas y fisiológicas en jugadores absolutos no profesionales durante partidos de fútbol 7: un estudio de caso. (Physical and physiological demands in non-professional adult soccer players during 7-a-side matches: a case study)

“…Son valores similares a los encontrados por Randers, Nybo et al (2010) en hombres y mujeres desentrenados, con picos cercanos al máximo, también observado en jugadores experimentados (Krustrup et al, 2005;Rampinini et al, 2007). Además, estos resultados son ligeramente superiores a los encontrados por Castagna et al, (2007) en futbol indoor 5 vs. 5, los cuales observaron que el 39% del tiempo total la FC …”

“…Sin embargo, ningún estudio ha examinado las demandas físicas y fisiológicas de esta modalidad deportiva en jugadores absolutos no profesionales, siendo un tipo de población del que existe escasa información (Randers, Nybo et al, 2010;Stroyer, Hansen y Klausen, 2004;Tessitore, Meeusen, Tiberi, Cortis, Pagano y Capranica, 2005).…”
