This study aimed to examine the validity of using bar velocity to estimate relative load in squat and bench-press exercises for both young men and women. Twenty-five men and 25 women performed a progressive loading test up to 1-RM in the squat and bench-press exercises, which were repeated after 2-weeks. Relationships between mean propulsive velocity and%1-RM were analysed. A second-order polynomial equation for predicting the corresponding velocity of each percentage of 1-RM was developed for men (validation). This equation was then applied in women (cross-validation). Moreover, a specific equation for women was developed (validation) and was also applied in a sub-sample of women (cross-validation). Close relationships (R2: 0.91–0.95) between bar velocity and relative load were observed in both sexes for squat and bench press. Men’s equation applied to women showed a high level of agreement, although lower bias and higher level of agreement was observed when a sex-specific equation was applied in women, both validation and cross-validation samples. In conclusion, lifting velocity can be used to accurately prescribe the relative load regardless of sex in both upper-body and lower-body exercises, although when estimating load from velocity measures it will be necessary to use the sex-specific equation for each exercise. ...

The effect of maximal strength and plyometric training on physical performance of young football players and game intensity Asadi, Mostafa (2020)Football is a sport that is played in every country and it is considered as an intermittent activity involving sudden actions such as tackling, jumping, kicking, change of direction, and short distance sprinting. Aerobic ...
Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players Lahti, Johan; Huuhka, Toni; Romero, Valentin; Bezodis, Ian; Morin, Jean-Benoit; Häkkinen, Keijo (PeerJ, 2020)Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted ...
Isometric force-time parameters in monitoring of strength training : with special reference to acute responses to different loading resistances Peltonen, Heikki (University of Jyväskylä, 2017)The aim of the present series of studies was to investigate acute neuromuscular responses to (1) different strength training loadings and using (2) different external resistances. In addition, chronic adaptations and ...
