The Effect of High Volume Power Training on Repeated High-Intensity Performance and the Assessment of Repeat Power Ability: A Systematic Review

Abstract

Background-High volume power training (HVPT) involves high volumes of high velocity resistance training, with the aim to improve repeated high intensity efforts (RHIE). Repeat power ability (RPA) is the ability to repeatedly produce maximal or near maximal efforts. Assessments of RPA using external loading may determine the ability to perform repeat high intensity efforts (RHIEs) typical of many sports and therefore provide useful information on the effectiveness of training.Objectives-1) Identify the different HVPT protocols; 2) Examine the acute responses and chronic adaptations to different HVPT protocols; 3) Identify different lower body RPA assessment protocols and highlight similarities, differences and potential limitations between each protocol, and; 4) describe the reliability and validity of RPA assessments.Methods-An electronic search was performed using SportDiscus, PubMed, CINAHL and Embase for studies utilising HVPT protocols and assessments of RPA. Eligible studies included peer reviewed journal articles published in English.Results-Twenty studies met the inclusion criteria of the final review. Of the eight longitudinal studies, three were rated as fair and five were rated as poor methodological quality, respectively. In contrast, all 12 cross-sectional studies were considered to have a low risk of bias. Preliminary evidence suggests that HVPT can enhance RHIE, RPA, anaerobic capacity, anaerobic power and aerobic performance. HVPT generally consists of 2-3 sessions per week, utilising loads of 30-40% 1 repetition maximum (RM), for 3-5 sets of 10-20 repetitions, with inter set rest periods of 2-3 minutes. RPA assessments can be valid and reliable and may provide useful information on an athlete's ability to perform RHIE and the success of HVPT programmes.The effect of HVPT on RHIE and RPA 3 This is a post-peer-review, pre-copyedit version of an article published in Sports Medicine.

Enhancing High-Intensity Actions During a Basketball Game After a Strength Training Program With Random Recovery Times Between Sets

“…With training time at a premium, the search for training methods able to concurrently target different physical fitness factors is necessary. In this regard, high-intensity muscle power training performed with incomplete recovery periods between sets (e.g., repeated power ability [RPA]) (27) has been recently proposed as an effective training method to simultaneously improve both isolated HIA (e.g., vertical and horizontal jumps, linear sprinting, and COD) and fatigue resistance during HIA (e.g., repeated sprints and COD) (18,34). For example, a combination of repeated power ability training in the squat exercise with superimposed vibrations and repeated-sprint exercises were substantially more effective in several HIA markers than the performance of repeated-sprint exercises alone by rugby players (34).…”

Mechanical, physiological and perceptual responses to different rest interval conditions during consecutive sets of the high-pull exercise

“…Further, results showed no modifications in time or bar displacement across sets, suggesting that power output maintenance is not always linked to changes in movement kinematics [37].…”

Stroke Kinematics, Temporal Patterns, Neuromuscular Activity, Pacing and Kinetics in Elite Breaststroke Swimming: A Systematic Review

“…The quality of eligible studies was assessed using the risk of bias scale developed by Hindle et al [ 6 ]. This scale is based on other evaluation checklists and has previously been used for the assessment of sports research [ 7 , 8 ]. Sixteen standards were used to evaluate article quality: three standards to study design, four standards to sample characteristics, four standards to methodology and five standards to results and discussion.…”
