This study aimed to analyze the time under tension (TUT) behavior in the bench press exercise performance in recreationally trained individuals. A systematic review was performed based on the PRISMA recommendations and registered on PROSPERO (CRD42022301830). MEDLINE (PubMed), Scopus, SPORTDiscus, and Lilacs (BVS) databases were consulted with the terms (resistance training [Title/Abstract]) OR (strength training [Title/Abstract]) AND (time under tension [Title/Abstract]). Cohort studies that analyzed the TUT in the bench press exercise in individuals with experience in resistance training were included. We used the Critical Appraisal Skills Program tool to analyze the methodological quality of the included studies. Thirteen studies met the inclusion criteria. The total number of participants was 215 individuals (179 men and 36 women). TUT was analyzed from the manipulation of each study variable. The behavior of the TUT in the bench press exercise varies according to the training protocol and method used. The TUT and the number of repetitions can vary to quantify the training volume.

Sprinting is a key component for many individual and team sports. Therefore, to enhance sprint performance, various training methods are widely used by coaches and practitioners, including maximum sprint speed and resisted sprint training. Resisted sprinting with sled towing is a method that has recently received considerable attention from the sport science community. However, to date, no consensus exists regarding its acute and chronic effects in team sport athletes. This narrative review aimed to (a) review and analyze the mechanics of sprinting under unresisted and resisted conditions with a specific focus on team sport disciplines; (b) provide a thorough and applied discussion on the importance of considering acute and chronic effects of sled loading on technique, electromyographic activity, and force production, as well as on the role of muscle architecture and neural factors in sled training; (c) analyze the effects of increasing sled loads during acceleration and maximum velocity phases on contact and flight phases, while concomitantly examining kinetic, kinematic, and neuromuscular aspects, because all these factors affect each other and cannot be properly understood in isolation.

The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.

This article seeks to analyze the needs analysis for emergency medical service (EMS) personnel and provide sample strength and conditioning programming for EMS personnel.

This article will analyze and compare squats with different loading positions to draw out practical applications for the personal trainer.

This article outlines some very basic procedures for video analysis that strength and conditioning professionals can use to identify the physical demands of specific activities.
