Introduction Muscle fatigue is characterized by reduced ability to produce maximum strength or power, and may differ between men and women. Changes in velocity of movement during exercise, and in the ability to produce strength after exercise, may help when comparing fatigue in men and women. Objective To analyze the differences between men and women in relation to number of repetitions, kinetics, kinematics and isometric force-time curve performance, and their respective muscle activation in horizontal leg press exercises. Methods Fifteen men and fifteen women underwent isometric force-time curve (Cf-t) and electromyographic (EMG) assessments before and after performing horizontal leg press exercises. The exercises were performed in three sets until voluntary exhaustion, at 70% maximal repetition. During the exercises, kinetic and kinematic variables were obtained by means of two force transducers, a linear position potentiometer and accelerometer adapted for the horizontal leg press and synchronized by a signal conditioning plate. Results The mean propulsive velocity significantly reduced between the first and last repetition of each series, with a similar reduction for men (-12.4 to -29.2%) and women (-29.2 to -35.6%). The same pattern was observed for the other kinetic and kinematic variables. The maximum voluntary contraction and peak force development rate also decreased for both men (-15.1 ± 8.7% and -26.9 ± 21.2%, respectively) and women (-13.9 ± 10.4% and -28.2 ± 11.5%, respectively). Conclusion Based on the different variables used to quantify the effect of fatigue during and after horizontal leg press exercises, the research found practically no differences between men and women. Level of evidence II; Comparative prospective study.

“…The obtained regression models make it possible to calculate the number of repetitions and rest interval to achieve the most rational load variant. These data supplement the results presented in the studies by Iermakov, Ivashchenko, Khudolii, and Chernenko (2020), Ivashchenko, Khudolii, Prusik, and Giovanis (2020) and form a methodology for studying training loads, which differs from the methods used in the studies by Arazi et al (2012), Ratamess et al (2012), Miranda et al (2010) in that research is conducted using an active 2 k FFE and materials are processed with the help of regression and discriminant analysis.…”

The purpose of the study was to obtain regression models of immediate and delayed training effect of strength loads in boys aged 8 years, based on a full factorial experiment. Materials and methods. The study participants were 48 boys aged 8 years. The experiment was performed using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. The study examined the impact of four variants of strength load on the immediate (ITE) and the delayed (DTE) training effect of orthogonal strength exercises modes and rest intervals in boys aged 8 years. Results. The study results show that in the proposed matrix of the 22 full factorial design, the chosen step of variation of factors is sufficient to study the influence of different modes of strength exercises on the dynamics of ITE in boys aged 8 years. Based on the data analysis, the study obtained regression models of load for calculating the ITE1, ITE2, and DTE. The obtained regression models make it possible to calculate the number of repetitions and rest interval to achieve the most rational load variant. Conclusions. The analysis of regression equations shows the interrelation between training effects: ITE1 —> ITE2 —> DTE. The value of ITE1, ITE2, and DTE at station I (exercises to strengthen arms and shoulders) and station II (exercises to strengthen abdominal muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of ITE1, ITE2 at station ІІІ (exercises to strengthen back muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of DTE – on the increase in the number of repetitions in a set and the reduction of the rest interval duration. The value of ITE1 at station IV (exercises to strengthen leg muscles) depends on the increase in the number of repetitions in a set and the reduction of the rest interval duration. To strengthen the DTE, it is necessary to reduce the number of repetitions in a set and the duration of the rest interval.

“…In contrast to Arazi, et al (2012), Ratamess, et al (2012), Miranda, et al (2010, the study obtained data on the impact of orthogonal variants of alternation of strength exercises and rest intervals on the training effect of strength training loads. The paper confirmed that the efficiency of discriminant analysis increases when using 2 k FFE active experiments (Neimark, & Teklina, 2012;Tort-Martorell, 2009, 2012;.…”

“…The effective use of loads in physical education goes hand in hand with control and targeted regulation of rest intervals between exercises, their repetition and training in general, as well as with management of training effects of exercises (Ivashchenko, 2016;Bosenko, 2016;Veremeenko, 2019). The importance of studying rest intervals between strength exercises is indicated in papers by Arazi, Mirzaei, Sangdevini, and Abadi (2012), Ratamess, Chiarello, Sacco, Hoffman, Faigenbaum, Ross, and Kang (2012), Miranda, Simão, DosSantos-Vigário, DeSalles, Pacheco, and Willardson (2010).

The study purpose was to determine the dynamics of training effects of orthogonal modes of strength training in boys aged 8 years. Materials and methods. The study participants were 48 boys aged 8 years. The experiment was performed using a 22 factorial design. The study materials were processed using the IBM SPSS 22 statistical analysis program.Discriminant analysis was performed. The study examined the impact of four variants of strength training loads on the immediate (ITE) and delayed (DTE) training effects of orthogonal modes of strength exercises and rest intervals in 8-year-old boys. Results. In the first variant of strength training, the largest contribution to the dynamics of training effects is made by the work performed at the first place “exercises to strengthen arm and shoulder muscles”; in the second variant, the largest contribution to the dynamics of training effects is made by the work performed at the third place “exercises to strengthen back muscles”; in the third variant, the largest contribution to the dynamics of training effects is made by the work performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places; in the fourth variant, the largest contribution to the dynamics of ITE is made by thework performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places. The most significant changes in the DTE are associated with the fourth place’s work “exercises to strengthen leg muscles”. Conclusions. The response to strength training load includes immediate and delayed training effects. Thus it can be argued that training effects can be classified using the given battery of tests based on discriminant analysis. The efficiency of discriminant analysis increases when using 2k FFE active experiments.
