Effect of nutri-bar in the development of stamina building and exercise-performance in young male-athletes

Abstract

Nutri-bars were prepared (110 g) using dates (64 g), dried apricots (16 g), cheddar cheese (8 g), whey protein isolate (12 g) and roasted-chickpea flour (10 g). Bars were prepared for Pakistani-athletes based on their calories and protein requirement (3500-3925 kcals/day, 1.4-1.8 g/kg body weight). Efficacy trials were performed (1, 15 and 30 days) to evaluate the effect of nutri-bars on blood serum profile, stamina building and body-composition. Results showed that hepatic-indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) were decreased (p > 0.05) during experimental-period. At day 30, ALT (6.8%), AST (1%) and ALP (0.4%) indicates the inhibitory effect of nutri-bar on the pathological serum-profile of athletes while significant increase (p > 0.05) was observed in total-protein (0.52%). Liver injury-indexes lactate dehydrogenase, Creatine kinase, total-cholesterol and total-glycerides showed a significant increase (p > 0.05) while low-density-lipoprotein and high-density-lipoprotein were decreased (p > 0.05). Effect of nutri-bar on body composition showed increase (p > 0.05) in body weight (kg) and body-mass index (BMI (kg/m 2). In the twelve-minutes running test, distance covered by athletes (p < 0.05) increased after 30 days as compared to day 1. The study revealed the significant (p < 0.05) effect of nutri-bar in developing the stamina building of Pakistani-athletes while the effect on the blood-serum profile was non-significant.

Development of energy‐rich protein bars and in vitro determination of angiotensin I‐converting enzyme inhibitory antihypertensive activities

“…These bars are an immediate energy source, meal replacement bars for increased muscle mass and weight management. An immense range of food products helps improve cognition ability, enhance physical output and muscular performance, increase endurance, and much more (Jabeen et al., 2021; Knapik et al., 2016). Among these products, the growth rate of protein‐rich products is very high, including whey protein isolate (WPI) and soy protein (Keogh et al., 2019).…”

Effect of milk protein concentrate supplementation on body composition and biochemical markers during a resistance training program

“…In addition, an evaluation of the functionality and benefits related to its consumption, such as mass gain, are of great value when seeking to develop products for practitioners of physical activities. Several products have been developed in this context, such as protein cereal bars (Jabeen et al, 2021a;Jabeen et al, 2021b), protein yogurts (McKinlay et al, 2022), protein foods of plant origin for vegans (Naclerio et al, 2021), among others.…”
