Relationships Between Punch Impact Force and Upper- and Lower-Body Muscular Strength and Power in Highly Trained Amateur Boxers
Publisher: Ovid Technologies (Wolters Kluwer Health)

DOI: 10.1519/JSC.0000000000003585
Abstract: Dunn, EC, Humberstone, CE, Franchini, E, Iredale, KF, and Blazevich, AJ. Relationships between punch impact force and upper- and lower-body muscular strength and power in highly trained amateur boxers. J Strength Cond Res 36(4): 1019–1025, 2022—This study examined the relationship between upper- and lower-body strength and power characteristics and punch performance in 28 highly trained male amateur boxers. Punch performance was assessed with a custom-built punch integrator using a 3-minute maximal effort punch test that contained straight- and bent-arm punches from the lead and rear hands. Peak punch force and force-time variables including impulse and rate of force development (RFD calculated to various points) were assessed. Force, power, and RFD of the upper and lower body were assessed with countermovement bench throw, isometric bench push, countermovement jump (CMJ), and isometric midthigh pull (IMTP) tests. Correlation and regression analyses revealed significant ( p 0.05) relationships between peak punch force and forces measured in CMJ and IMTP tests. In addition, peak punch force was moderately and significantly correlated to body mass, but RFD in the lower body was not. Moreover, no meaningful relationships between punch performance characteristics and any upper-body strength or power parameter were identified. The results of this study show that lower-body strength but not RFD had a moderate to strong positive and significant correlation to peak punch force production. Although upper-body strength and power are expected to be important in boxing, they did not discriminate between boxers who punched with higher or lower peak force nor were they correlated to peak punch force. Training that improves lower-body strength without increasing total body mass (to maintain weight category) may positively influence punch capacity in highly trained amateur boxers.

Reliability and Usefulness of Time-Motion and Physiological Responses in Simulated Judo Matches
Publisher: Ovid Technologies (Wolters Kluwer Health)
Date: 09-2020
DOI: 10.1519/JSC.0000000000002727
Abstract: Franchini, E, Dunn, E, and Takito, MY. Reliability and usefulness of time-motion and physiological responses in simulated judo matches. J Strength Cond Res 34(9): 2557–2564, 2020—Match simulations have been used to investigate different interventions in judo. However, no study has assessed the reliability of actions performed and the physiological responses to the match and its usefulness. Thus, 2 studies were conducted to verify the reliability of time-motion and physiological responses to judo matches. In the first study, 25 judo athletes performed one 5-minute judo match simulation twice, 1 week apart, and had their heart rate and blood lactate measured. In the second, 12 judo athletes performed one 5-minute judo simulation 4 times, 72 hours apart, and had their primary actions and match temporal structure analyzed. Comparisons between conditions, reliability (using intraclass correlation coefficient, ICC), typical error (TE), smallest worthwhile change (SWC), and minimal detectable change were determined. The main findings indicated that: (a) there were no differences between matches for any variable (b) ICCs were significant (except for blood lactate before matches in both studies) with 6 variables presenting large (number of attacks plus defensive actions, number of scoring actions, efficiency, number of sutemi-waza, time per combat sequence, and time per interval phase time), and the remaining 15 variables presenting very large reliability (c) TE was higher than SWC for all variables when small differences were considered. Moderate changes in peak blood lactate and the change in blood lactate (in both studies), and time in tachi-waza could be properly detected however, only large changes could be detected for all other variables, suggesting that investigations using match simulation as an outcome variable may only detect large changes.
The effect of fatiguing lower-body exercise on punch forces in highly-trained boxers.
Publisher: Informa UK Limited
Date: 10-05-2022
DOI: 10.1080/17461391.2021.1916085
Abstract: This study aimed to examine the effect of intense intermittent lower-body and trunk exercise (rowing) on punching performance in 28 highly-trained male amateur boxers. Straight- and bent-arm punch performances were assessed with a custom-built punch integrator using a 3-min maximal-effort punch test, completed in both non-fatigued (ROW
