“…The dip is a popular bodyweight exercise frequently used to strengthen the muscles of the upper limb and trunk, and more specifically, the triceps brachii (TB) and pectoralis major (PM) [ 1 , 2 ]. There are many technique variations of the dip which can either decrease movement complexity (i.e., the bench dip) or increase movement complexity (i.e., the ring dip), which have recently been shown to exhibit differing neuromechanical profiles [ 3 ]. However, the most common variation appears to be the bar dip [ 4 ].…”

The purpose of this study was to profile and compare the bar dip’s kinematics and muscle activation patterns in non-fatigued and fatigued conditions. Fifteen healthy males completed one set of bar dips to exhaustion. Upper limb and trunk kinematics, using 3D motion capture, and muscle activation intensities of nine muscles, using surface electromyography, were recorded. The average kinematics and muscle activations of repetitions 2–4 were considered the non-fatigued condition, and the average of the final three repetitions was considered the fatigued condition. Paired t-tests were used to compare kinematics and muscle activation between conditions. Fatigue caused a significant increase in repetition duration (p < 0.001) and shifted the bottom position to a significantly earlier percentage of the repetition (p < 0.001). There were no significant changes in the peak joint angles measured. However, there were significant changes in body position at the top of the movement. Fatigue also caused an increase in peak activation amplitude in two agonist muscles (pectoralis major [p < 0.001], triceps brachii [p < 0.001]), and three stabilizer muscles. For practitioners prescribing the bar dip, fatigue did not cause drastic alterations in movement technique and appears to target pectoralis major and triceps brachii effectively.

The aim of this study was to investigate the anthropometric characteristics of streetlifting athletes in the different body weight categories and to develop specific equations to predict the individual performance in the different exercises included in competitive programs (chin-up, dip, muscle-up and squat). A total of 79 athletes (60 men and 19 women; age: 26.1 ± 6.4 y; body mass: 72.7 ± 13.2 kg; height: 171.7 ± 8.9 cm) were tested in accordance with the Italian National championships. Athletes were tested for anthropometry and body composition before the competition, and the performance in each lift was registered. A partial correlation of 0.47 and 0.60 was detected between arm girth and chin-up and dip performance, respectively. On the contrary, body fat was negatively correlated with the same exercises (r = −0.42). Squat performance appeared mainly determined by fat-free mass and thigh cross-sectional area, while body fat did not affect the performance in this exercise. The prediction equations developed were based on anthropometric and body composition parameters and showed near-perfect correlations with the participants’ competitive results (R2 between 0.66 and 0.90). The normative data presented in this investigation and the prediction equations developed may help coaches and practitioners in athlete evaluation and comprehension of the key factor of streetlifting performance.

Wheelchair fencing is a medium-distance combat sport in which the wheelchair is fixed to the floor. This requires a maximum concentration and gestational speed. Refined techniques and fatigue tolerance are essential to achieve competitive results. Aim: The main objective of this study was to measure the speed and muscular participation of a direct attack gesture with and without fatigue in a sample of elite wheelchair fencers. Methods: The maximal isometric force, gestural speed, and resistance to gestural velocity were estimated in 10 elite performed direct fencers. Results: The results revealed that sitting height and wingspan were important factors in achieving the highest speed, especially in women (r = 0.9; p = 0.07). Other factors, such as the elbow angle where the closed position was better, affected muscle contraction in both categories of athletes (p = 0.01). The onset of fatigue was earlier in category B than in category A, with greater variation in direct attack movement. The results highlight the importance of analyzing direct attacks for the best application of quick force, speed, and muscle participation, as well as identifying the onset of technical deterioration to devise a competitive strategy. These parameters may allow for precise design of conditioning sessions for elite wheelchair shooters.
