“…The current study compares a normal tube with a pre-stressed tube experimentally to assess the effect of stress-induced through pre-tensioning technique, in increasing the SEA. The pre-tensioning approach has been attempted because the thing tube with induced prestress during manufacturing can be assembled in the car Gattineni V et al (7). Otherwise, practically it would be difficult and additional accessories could be needed to induce prestress through post-tensioning techniques.…”

The use of materials like CFRP has shot into prominence to achieve lightweight designs without compromising on structural integrity. Circular thin tubes are often employed in passenger cars as energy absorbers to absorb the impact energy during an accident. When such tubes are made of materials like CFRP it contributes to weight reduction besides leading to reduced fuel consumption. Also due to their lower weight, such tubes shall be capable of absorbing more energy per unit mass compared to metallic designs, which is defined as specific energy absorption capacity (SEA). Pre-stressing techniques are widely used by civil engineers across the globe to impart more stress/energy bearing capacity for the structures. Based on pre-stressing principles, the introduction of pre-tension during the fabrication stage for thin CFRP tubular structures has been experimentally studied to validate the applicability of pre-stress concepts for more SEA. The study investigates experimentally the additional advantage prestressing can bring for a CFRP tube in terms of SEA improvement.

“…In a study of high school girls basketball players, Gattineni V used plyometric training to develop lower body explosiveness in girls basketball players. 3 After a 16-week intervention experiment, 17 athletes improved their performance in the 30-meter sprint, run-up reach, and quarter-and-three sprints that reflected lower-body explosiveness. Ali H conducted a comparative study of single-leg resistance training according to the special characteristics of basketball projects, twelve subjects were divided into a single-leg training group and a double-leg training group for a 10-week intervention experiment.…”

Introduction: Basketball presents unique competitive characteristics, requiring athletes a high level of strength, especially explosive strength. Objective: Study the effect of combined training on the explosive power of lower limbs in basketball players. Methods: The author selected 18 basketball players, equally distributed with the random method into a unipodal combined training group (S group), a two-legged combined training group (D group), and a conventional strength training group (W group), for the three-test data. Statistical analysis was performed on the data collected from the experiment. Results: There was a significant difference in approach height and three-quarter sprint in group S (p<0.05). The difference was not evident in the height of touch in situ (p>0.05). In group D, there was a significant difference in situ touch height p<0.01. There was no significant difference in the results of the three test indicators in group W (p>0.05). Conclusion: Compared to conventional strength training, unipodal combined training is more effective for the development of explosive strength in the lower limbs of basketball students. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
