Comparison of Olympic vs. Traditional Power Lifting Training Programs in Football Players

The Effects of Circuit Strength Training on the Development of Physical Fitness and Performance-Related Variables in Handball Players

“…Helland et al (2016) detected no significant increase in 30 m sprint times after eight weeks of tri-weekly weightlifting training when compared to a power training group. Likewise, Hoffman et al (2004) saw no significant increase in the 30 m sprint time of young athletes after 15 weeks of weightlifting training, 4 times per week.…”

“…In our study, gains for the upper and lower limbs (circuit training: 18.5% and 15.2% for the bench-press and half-squat, respectively) were even larger than those observed by Gorostiaga et al (2005) and Hermassi et al (2011) possibly because of differences in the initial level of physical fitness of the players or the choice of training exercises. Hoffman et al (2004) also reported significant increases in the 1RM back-squat, but no significant increases in 1RM bench-press scores of young athletes after 15 weeks of weightlifting training. Our study found gains in vertical jump height (7.8 and 12.5% for the CMJ and SJ, respectively), similar to those seen in handball players (Gorostiaga et al, 1999) and junior soccer players (7.5% and 10%, respectively) (Chelly et al, 2009).…”

Effects of Split Style Olympic Weightlifting Training on Leg Stiffness Vertical Jump Change of Direction and Sprint in Collegiate Volleyball Players

“…Studies have shown strong relationships between weightlifting movements and sprint [5] and COD [19]. Hoffman et al [34] compared their weight lifting and power lifting trainings programs and found a 175% improvement in their 40-yard distance. Tricoli et al [26] reported an improvement in sprinting performance after an 8-week training intervention, which was performed thrice a week for a weightlifting group compared with the vertical jumping training group.…”

Métodos de entrenamiento de la fuerza para la mejora de las acciones en el fútbol [Strength Training Methods for Improving Actions in Football]

“…A number of strength training methods have been used to improve performance in football (Cronin & Hansen, 2005;Young, 2006). These strategies can be classified by the training methods they bring into play: traditional exercises (Kotzamanidis, Chatzopoulos, Michailidis, Papaiakovou, & Patikas, 2005;Ronnestad, Nymark, & Raastad, 2011) such as squats and deadlift, which are associated with a deceleration of the load towards the end of the range of motion (Newton, Kraemer, & Häkkinen, 1996); ballistic exercises (Loturco, Ugrinowitsch, Tricoli, Pivetti, & Roschel, 2013;Loturco et al, 2015), in which the body displacement occurs due to the execution of the movement at the highest possible speed (Cor mie, Mc-Guigan, & Newton, 2011); Olympic exercises (Hoffman, Cooper, Wendell, & Kang, 2004) such as the clean and jerk, the snatch and their variations, in which the athlete has to accelerate the bar throughout the propulsive phase of the movement (Schilling et al, 2002 ); plyometric exercises (Brito, Vasconcellos, Oliveira, Krustrup, & Rebelo, 2014;Chelly et al, 2009), which are ballistic and generally performed without external resistance or with very little resistance (Wathen, 1993); eccentric overload exercises (De Hoyo, Pozzo et al, 2015;Tous-Fajardo, Gonzalo-Skok, Arjol-Serrano, & Tesch, 2016), in which the eccentric phase of the movement increases to accentuate the effects of this type of muscle contraction (De Hoyo, Pozzo et al, 2015); and the combination of some of them in complex contrast training (Buchheit, Mendez-Villanueva, Delhomel, Brughelli, & Ahmaidi, 2010;Chelly et al, 2010).…”

“…S'han utilitzat diferents mètodes d'entrenament de força per a la millora del rendiment en el fut bol (Cronin & Hansen, 2005;Young, 2006). Aquestes estratègies poden ser classificades segons els mitjans d'entrenament que s'empren: exercicis tradicionals (Kotzamanidis, Chatzopoulos, Michailidis, Papaiakovou, & Patikas, 2005;Ronnestad, Nymark & Raastad, 2011) com l'esquat i el pes mort, els quals estan associats amb una desacceleració de la càrrega cap al final del rang de moviment (Newton, Kraemer, & Häkkinen, 1996); exercicis balístics (Loturco, Ugrinowitsch, Tricoli, Pivetti, & Roschel, 2013;Loturco et al, 2015), en els quals té lloc el desplaçament del propi cos a causa de l'execució del moviment a la màxima velocitat possible (Cormie, McGuigan, & Newton, 2011); exercicis olímpics (Hoffman, Cooper, Wendell, & Kang, 2004) com la carregada, l'arrencada i les seves variacions, en els quals l'esportista ha d'accelerar la barra al llarg de tota la fase propulsiva del moviment (Schilling et al, 2002); exercicis pliomètrics (Brito, Vasconcellos, Oliveira, Krustrup, & Rebel•lo, 2014;Chelly et al, 2009), de naturalesa balística i realitzats generalment sense resistència externa o amb una resistència molt petita (Wathen, 1993); exercicis amb sobrecàrrega excèntrica (De Hoyo, Pozzo et al, 2015;Tous-Fajardo, Gonzalo-Skok, Arjol-Serrano, & Tesch, 2016) en els quals la fase excèntrica del moviment s'incrementa per accentuar els efectes d'aquest règim de contracció (De Hoyo, Pozzo et al, 2015), i la combinació d'alguns d'ells en el mètode de contrastos (Buchheit, Mendez-Villanueva, Delhomel, Brughelli, & Ahmaidi, 2010;Chelly etal., 2010).…”
