Abstract
This study aimed to analyze the performance of the vertical jump with counter movement (CMJ), in university handball athletes, immediately after the maximum strength training in multiple series and after 10 and 15min of rest. Twelve male athletes participated, age 20.9±2.4 years old, height 1.78±0.05m and Body Mass Index (BMI) 28.74±8.1kg/m2. After the tests and retests of 1 repetition maximum (1RM) for the dominant and non-dominant sides, in the leg extension, the volunteers performed crossover after 48 hours of the training sessions. CMJ measurements were collected before and immediately after each training protocol and after 10 and 15min of rest. Passive recovery between sets was three minutes. The intervals between training protocols were at least 45min. There were no statistical differences for the CMJ between the moments pre-, post-training session, 10 and 15min of rest in the different protocols, but progressive increases in the CMJ variables were observed, extending up to the 15th minute of rest, in all training protocols when comparing the results of the means of the CMJ variables of the moments post-training session, 10 and 15min of rest with the averages of the variables from the pre-training session, being more evident in the alternate unilateral protocol, which, unlike the other protocols of the study, performed series with the two lower limbs. It was evidenced that the training protocols of short duration and with high dynamic efforts, previously performed, influenced the performance of the CMJ, favoring for the transient improvement of the explosive muscular strength of the athletes.
Highlights
Handball is a highly demanding sport, which requires several complex motor gestures, requires athletes to perform intermittent efforts, involving frequent body contact, several displacements at different speeds, high intensity, and strength actions (Hermassi et al 2018)
Performance of Brazilian university handball players in the vertical jump after maximum strength training and specific sports performance of handball players, exercises should be included in the training sessions to develop greater resistance to intermittent high-intensity and short-term efforts, as well as improving agility, speed, strength, and power (Hermassi et al 2010; Hermassi et al 2011; Dello Iacono et al 2016)
A strategy used for the acute improvement of the performance of the jump is the post-activation potentiation (PAP), which comprises in the transient increase of the capacity of production of muscular power observed after the accomplishment of the resistance training (RT) with exercises of maximum or near voluntary stimuli (Ebben 2006; Dello Iacono and Seitz 2018)
Summary
Handball is a highly demanding sport, which requires several complex motor gestures, requires athletes to perform intermittent efforts, involving frequent body contact, several displacements at different speeds, high intensity, and strength actions (Hermassi et al 2018). Performance of Brazilian university handball players in the vertical jump after maximum strength training and specific sports performance of handball players, exercises should be included in the training sessions to develop greater resistance to intermittent high-intensity and short-term efforts, as well as improving agility, speed, strength, and power (Hermassi et al 2010; Hermassi et al 2011; Dello Iacono et al 2016). The combination of resistance training (RT) and plyometric is effective in promoting and improving results for the vertical jump (Perez-Gomez and Calbet 2013), one of the essential motor valences for some sports, having research that used the vertical jump as a test to dimension the performance of athletes (Dal Pupo et al 2014; Dobbs et al 2015). A strategy used for the acute improvement of the performance of the jump is the post-activation potentiation (PAP), which comprises in the transient increase of the capacity of production of muscular power observed after the accomplishment of the RT with exercises of maximum or near voluntary stimuli (Ebben 2006; Dello Iacono and Seitz 2018)
