The Effects Of Complex Elastic Band Training On Physical Fitness Components In Junior Female Handball Players, Mehrez Hammami, Ryland Morgans, Piotr Zmijewski

Baltic Journal of Health and Physical Activity

Introduction: The aim of this study was to examine the effects of a 10-week complex elastic band training (CEBT) program on athletic performance in junior female handball players. Methods: Participants (16.2 ± 0.5 years) were randomly assigned to an intervention group (IG; n = 16) or control group (CG; n = 14). The IG group performed CEBT twice a week during the 10-week intervention, which included eight 35-minute sessions, progressing in number of sets and band resistance for each specific exercise. The CG maintained regular in-season training. The modified T-test (T-half), squat jump (SJ), countermovement jump (CMJ), standing long jump …

An Assessment Of Isometric Muscle Strength And The Hamstring: Quadriceps Ratio Among Males Trained With Free Weights Vs. Machines, Geferson Honorato Da Silva, Alex Souto Maior Jul 2022

An Assessment Of Isometric Muscle Strength And The Hamstring: Quadriceps Ratio Among Males Trained With Free Weights Vs. Machines, Geferson Honorato Da Silva, Alex Souto Maior

Baltic Journal of Health and Physical Activity

Introduction. The purpose of this study was to assess the isometric muscle strength (IMS) of the knee extensors and flexors, bilateral asymmetry (BA) and the hamstring: quadriceps ratio (H:Q ratio) between the dominant leg (DL) vs. the non-dominant leg (NDL) of males trained with free-weights vs. machines. Material and Methods: Thirty males were recruited and separated into two groups: Free-weights (n = 15) and Machines (n = 15) groups. All study participants performed the IMS testing for knee extensors and flexors in the DL and NDL using a commercially available load cell. The highest value obtained from the three trials …

An Interaction Between Exercise Order And Rest Interval During Lower-Body Resistance Exercise, Hamid Arazi, Bahman Mirzaei, Morteza Sangdevini, Mohammad Reza Hossein Abadi

Baltic Journal of Health and Physical Activity

Background: The purpose of the present study was to compare the influence of two- and five-minute rest intervals on the number of repetitions per set and total repetitions per exercise for a lower-body workout performed in 2 different sequences. Material/Methods: 12 resistance trained men completed 4 experimental resistance exercise sessions. All sessions consisted of 3 sets with a 10-repetition maximum load for 4 lower-body exercises. Two different exercise sequences (i.e., A or B) were performed with either 2- or 5- minute rest between the sets and the exercises, respectively. The order of exercises for sequence A2 (SEQA2) and sequence A5 …

Baltic Journal of Health and Physical Activity

Background: The purpose of this study was to determine the effects of whey protein supplementation on performance and hormonal changes during an 8-week resistance training program in novice weight trained men. Material/Methods: Forty recreational weight trained men were randomly divided into a whey protein supplementation (WP) group (n=20), and a placebo (PL) group (n=20). Each group was given either whey protein or a placebo in a double-blind manner to be taken orally for eight weeks (1.8g/kg/day). WP and PL groups performed the same weight training program 3 days, each week for 8 weeks. The training consisted of 3 sets of …

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Strategies aiming to promote weight loss usually include anything that results in an increase in energy expenditure (exercise) or a decrease in energy intake (diet). However, the probability of losing weight is low and the probability of sustained weight loss is even lower. Herein, we bring some questions and suggestions about the topic, with a focus on exercise interventions. Based on the current evidence, we should look at how metabolism changes in response to interventions instead of counting calories, so we can choose more efficient models that can account for the …

CrossFit can be described as a relatively new fitness training method that is based on a variety of high-intensity weight training, body weight movements, and cardiovascular exercise. Given the recent rise in CrossFit establishments, the purpose of this study was to explore the relationships between basic need satisfaction (autonomy, relatedness, competence), behavioral regulation toward CrossFit, and actual participation behaviors within the framework of Self-Determination Theory. CrossFit participants (N = 206; Mage = 37.6 years), majority Caucasian (76%), females (58%), who reported attending three (n = 91; 44.2%) and five (n = 78; 37.9%) CrossFit sessions per week completed online surveys …

Greater Strength Gains After Training With Accentuated Eccentric Than Traditional Isoinertial Loads In Already Strength-Trained Men, Simon Walker, Anthony J. Blazevich, Greg Haff, James J. Tufano, Robert Newton, Keijo Häkkinen

Research outputs 2014 to 2021

As training experience increases it becomes more challenging to induce further neuromuscular adaptation. Consequently, strength trainers seek alternative training methods in order to further increase strength and muscle mass. One method is to utilize accentuated eccentric loading, which applies a greater external load during the eccentric phase of the lift as compared to the concentric phase. Based upon this practice, the purpose of this study was to determine the effects of 10 weeks of accentuated eccentric loading vs. traditional isoinertial resistance training in strength-trained men. Young (22 ± 3 years, 177 ± 6 cm, 76 ± 10 kg, n = …

The Acute Effects Of Moderately Loaded Concentric-Only Quarter Squats On Vertical Jump Performance, Aaron Crum, Naoki Kawamori, Michael Stone, Guy Haff

Greg Haff

2012-Limited research exists examining the effect of moderately loaded conditioning activities that are employed as part of a strength-power potentiating complex (SPPC). Additionally, no studies to date have explored the effects of using a concentric-only quarter back squat protocol as part of an SPPC. Therefore, the purpose of this study was to examine the effects of a moderately loaded (50-65% of 1RM) concentric-only quarter back squat protocol on the occurrence of potentiation effects at various time points. Twenty men who could quarter back squat a minimum of 2.4 times their body mass (3.7 ±: 0.7 kg-per body mass) participated in …

Effects Of Two Contrast Training Programs On Jump Performance In Rugby Union Players During A Competition Phase, C K Argus, N D Gill, J W Keogh, Michael Mcguigan, W G Hopkins

Research outputs 2012

Purpose: There is little literature comparing contrast training programs typically performed by team-sport athletes within a competitive phase. We compared the effects of two contrast training programs on a range of measures in high-level rugby union players during the competition season. Methods: The programs consisted of a higher volume-load (strength-power) or lower volume-load (speed-power) resistance training; each included a tapering of loading (higher force early in the week, higher velocity later in the week) and was performed twice a week for 4 wk. Eighteen players were assessed for peak power during a bodyweight countermovement jump (BWCMJ), bodyweight squat jump (BWSJ), …
