Carbohydrate (CHO) mouth rinse has been shown to enhance aerobic endurance performance. However, the effects of CHO mouth rinse on muscular strength and endurance are mixed and may be dependent on dosage of CHO. The primary purpose was to examine the effects of different dosages of CHO rinse on strength (bench press 1 repetition maximum [1-RM]) and muscular endurance (40% of 1-RM repetitions to failure) in female athletes. Sixteen resistance-trained females (age: 20 ± 1 years; height: 167 ± 3 cm; body mass: 67 ± 4 kg; BMI: 17 ± 2 kg/m2; resistance training experience: 2 ± 1 years) completed four conditions in random order. The four conditions consisted of a mouth rinse with 25 mL solutions containing either 6% of CHO (Low dose of CHO: LCHO), 12% CHO (Moderate dose of CHO: MCHO), 18% CHO (High dose of CHO: HCHO) or water (Placebo: PLA) for 10 s prior to a bench press strength and muscular endurance test. Maximal strength (1-RM), muscular endurance (reps and total volume), heart rate (HR), ratings of perceived exertion (RPE) and glucose (GLU) were recorded each condition. There were no significant differences in strength (p = 0.95) or muscular endurance (total repetitions: p = 0.06; total volume: p = 0.20) between conditions. Similarly, HR (p = 0.69), RPE (p = 0.09) and GLU (p = 0.92) did not differ between conditions. In conclusion, various doses of CHO mouth rinse (6%, 12% and 18%) have no effect on upper body muscular strength or muscular endurance in female athletes.

Purpose.The purpose of this study was to determine the effects of increasing the volume of weight-training from one to three sets upon body composition and muscular strength.Methods.Sixteen male weight-trainers volunteered to act as subjects and were randomly assigned to one of two training groups. Supervised weight-training targeting the upper body was conducted three times per week for eight weeks using one set (n=8) or three sets (n=8) of six repetitions to fatigue. Subjects were measured before and after the training intervention for (1) strength performance (Nand kg) and (2) adiposity (sum of seven skinfold thicknesses in mm).Results.Both training groups improved significantly (20.7%) in terms of muscular strength (P<0.05) with no differences being observed between the one set (21.98% increase) and three set group (20.71% increase) after the training interventions (P>0.05). Significant decreases were also observed for skinfold measures in the one set group (P<0.05).Conclusions.One set of high intensity resistance training was as effective as three sets for increasing the strength of muscle groups in the upper body. The one set protocol also produced significantly greater decreases in adiposity.

The aim of this study was to analyze the reliability and the validity of the handgrip, basketball throw and pushups tests in children aged 6–12 years. One hundred and eighty healthy children (82 girls) agreed to participate in this study. All the upper body muscular fitness tests were performed twice (7 days apart) whereas the 1 repetition maximum (1RM) bench press test was performed 2 days after the first session of testing. All the tests showed a high reproducibility (ICC > 0.9) except the push-ups test (intertrial difference = 0.77 ± 2.38, p < .001 and the percentage error = 9%). The handgrip test showed the highest association with 1RM bench press test (r = .79, p < .01; R2 = .621). In conclusion the handgrip and basketball throw tests are shown as reliable and valid tests to assess upper body muscular strength in children. More studies are needed to assess the validity and the reliability of the upper body muscular endurance tests in children.

The study aimed to identify the effectiveness of a training program by Weight to improve the muscular strength of the upper body for the students of the Industrial Welding Department at Jubail Technical Institute. The researcher followed the experimental approach in his study; where the pre- and post-dimensional design of an experimental group consisting of (55) students from the Industrial Welding Department at the institute was used. The study included a training program consisting of (18) units with (24) training hours for a period of (6) weeks. The study concluded that there were statistically significant differences between the pre- and post-measurement among the students in the experimental group from the Industrial Welding Department at Jubail Technical Institute in favor of the post measurement. In light of the results, the study recommends the necessity of paying more attention to the training programs that help to improve the muscular strength in the upper part of the body for the students of the Industrial Welding Department to enable them to perform their duties effectively.

Background Physical activity (PA) (e.g., sport, physical education) promotes the psychophysical development of children, enhances health and wellbeing, offers opportunities for enjoyable experiences, and increases self-efficacy. Methods In the DEDIPAC framework, we conducted a naturalistic, cross-sectional study to evaluate the effects of a school-based, long-term intervention on fitness (i.e., cardiovascular endurance, muscular strength, flexibility, speed, and finger dexterity), body mass index (BMI), PA levels, sedentary levels, enjoyment, and physical self-efficacy in primary school children. A group of Italian children (41 boys and 39 girls, aged 10–11 years) involved in the project—named “Più Sport @ Scuola” (PS@S)—was compared with a group of children (41 boys and 39 girls) of the same age not involved in the project. Results After a four-year long attendance to the PS@S project, participants reported higher scores of cardiovascular endurance, muscular strength, enjoyment, and physical self-efficacy compared to children not involved in the project. Correlation analysis results showed that muscular strength scores correlated positively with BMI, PA levels, and enjoyment. Flexibility of the upper body was positively related to physical self-efficacy, and negatively related to speed and BMI. Conclusions Findings suggest that the PS@S project enhanced fitness level, enjoyment, and physical self-efficacy of children.
