Effects of caloric restriction on anthropometrical and specific performance in highly-trained university judo athletes

Abstract

Purpose:The purpose of this study was to determine the ultimate body mass, performance, and nutritional characteristics of the Algerian judo junior athletes, and also analysing the impact of nutritional intakes on stabilising Weight loss according to special performance of judo athletes. Material:Twenty-one male university athletes (aged: 21.45 ± 1.32; height: 1.81 ± 0.45 m; and body mass: 73.9 ± 4.1 kg) participated in this study during a period of stabilising Weight loss before and after 15 days of caloric restriction. Athletes were submitted to anthropometrical measurements and performed the Special Judo Fitness Test. Values for nutrient intakes were obtained from a 15 day food record kept during a training camp period of Weight maintenance and after a 15-day caloric restriction.Results:caloric restriction resulted in significant decreases in body mass (73.73 ± 2.1) and performance. However, Special Judo Fitness Test index increased significantly (14.00 ± 1.75) during caloric restriction in comparison to stabilising Weight loss.Conclusion:Exercise and caloric restriction lead to determine the ultimate Weight and physical performance. The present study provides baseline nutritional data that can be used in the prescription of individual training programs for university judo Athletes.

The effects of tow protocol cold water immersion on the post match recovery and physical performance in well-trained handball players

“…The advanced physiological mechanisms when using fractional immersions show a pumping effect caused by vasoconstriction and vasodilatation, which occur due to temperature change. This pumping effect stimulates the transport of waste and nutrients into the body [8,27]. In contrast, continuous immersions are advocated as a result of increased exposure to cold and the effects of vasoconstriction and hydrostatic pressure which together facilitate processes such as, rapidly decreasing body temperature, and acceleration of processes associated with decreased pain [28].…”

“…These physiological results demonstrate that the physiological and functional symptoms associated with Post-Effort Muscle Pain (EPMP) associated with the reduction of acute inflammation [12] , as well as the presence of symptoms in the muscle and the effect of hydrostatic [13,14] pressure [6] have accelerated recovery. Another mechanism could be related to cold exposure that has shown the potential for activation of the transient 8-melastatin receptor [27,47] which is related to pain and temperature sensation [48,49] . Once activated, TRPM8 has an analgesic effect given by the action of the interphas neurons the inhibitory interphase [48,50] and which improves the perception of DMPE and increases the feeling of recovery [28] .…”

A hypoenergetic diet with decreased protein intake does not reduce lean body mass in trained females

“…Severe energy restriction can, however, be detrimental to various exercise performance parameters, including strength, sprinting, jumping, and sport-specific fitness tests (Fortes et al 2017;Garthe et al 2011;Lalia et al 2018;Ribas et al 2019). In the present study, exercise performance was maintained and, in the most part, unaffected by protein intake.…”

“…Hypoenergetic diets have demonstrated efficacy as a weight loss strategy in athletic populations. However, the desired loss of fat mass (FM) is often concomitant with a reduction in lean body mass (LBM) (Pons et al 2018;Willoughby et al 2018), which can be detrimental to athletic performance (Lalia et al 2018). Therefore, weight loss strategies that attenuate the loss of LBM have been investigated.…”

Using Factor Analysis as a Tool for Measuring the Quality of Life of University Students

“…Thus, the quality of life in this sense refers to the individual's subjective evaluations of his life circumstances (Hofstede, 1984). In addition to this, there is a link between the individual in terms of his internal personal entity that is shown on his judged external behaviour (Chrara, Raoui, Belkadi, Hocine, & Benbernou, 2018;Markus & Kitayama, 1991). Here we can make relation between a person's personality and his points of view of the life issues and his reactions and feedbacks to life situations the negative one or the positive.…”
