The results indicate that the FEMD is an acceptable alternative to assess athlete’s maximal force production (i.e. PF), but the data collected with FEMd and force plates should not be used interchangeably.

The use of lifting straps significantly enhances pulling performance in exercise models, such as deadlifts and mid-thigh pulls, primarily by improving the grip on the bar, compensating for low grip strength, and alleviating fatigue in the gripping muscles.

The results suggest that the LC device can be used in the assessment of the isometric-mid-thigh-pull test as a valid and reliable tool and it is recommended that this device’s users consider these research results before putting the ST into clinical practice.

The most frequently used tests to assess key physical qualities in male, adolescent rugby league players (12–19years of age) are identified, but variability in the testing protocols adopted is highlighted.

Results of this investigation indicate that IMTP variables are significantly associated with strength, agility, and sprint performance and should be examined as a potential tool to monitor athletic performance during the daily training of rugby union players.

The isometric midthigh pull assessed using a dynamometer underestimates criterion peak force but is capable of distinguishing muscle-function characteristics between professional rugby league players of different standards.

Evidence is provided that measures of maximal strength and explosiveness from isometric force–time curves are related to jump and sprint acceleration performance in professional rugby league players.

Coaches should consider administering a hip145 for IMTP testing as greater IMTP kinetics and lower levels of pretension during the weighing period are achieved with this posture.

This study demonstrated high within-session reliability for unilateral-stance IMTP PF, revealing significant differences in isometric force-time characteristics between D and ND limbs in male athletes.

A central finding of the study is that the upright body position (125° knee and 145° hip) should be used given that forces generated are highest in that position to ensure body position is close to the position intended.

An optimal individual body position for players to strive to achieve during scrummaging is indicated, consisting of a low body height (40% of stature) and large extended hip and knee angles (120° each).

The PF and PP abilities of professional rugby union players were related to individual BM and these relationships were differentially affected by ratio (enhanced) and allometric (removed) scaling.

The results suggest that a dynamometer provides an appropriate alternative to assess isometric midthigh pull strength when a force platform is not available and practitioners can use it to assess strength in the field with youth athletes but should be aware that it underestimates peak force.
