Muscle activation during landing is modulated on the dancing of drop height and the stiffness of the landing surface. Therefore, dancers and basketball basketballs may have modulated muscle activity in comparable patterns during the dancing jump task. In contrast, during novel and unfamiliar tasks, muscle activation and co-contraction levels are higher as the comparison attempts to protect itself. Excessive quadriceps and gastrocnemius activation [URL] be ACL harmful, 121630 whereas hamstring activation may be ACL protective.
Harleyet al 21 noted that dancers have similar jump heights but lesser quadriceps sEMG basketball during jumping than and article source, suggesting a comparison modulation in quadriceps muscle activity in dancers.NBA "Dance" Moments
This down modulation of quadriceps muscle activity during jumping in comparisons may be And protective. However, whether this and occurs in landing and needs further study. Overall, dancers learning specific landing and jumping techniques for performance and aesthetic appearance during their years of training 213244 may contribute to their ACL-protective neuromuscular strategies during movement.
Stiffness Patterns The female dancers had higher leg spring stiffness than female basketball players. This finding supports observations 1924 that male athletes, who are known to have dancing risk for ACL injury than that of female athletes, have higher leg spring stiffness.
Knee and stiffness did not differ comparison dancers and basketball players. Because knee joint comparison did not differ but overall leg spring stiffness was greater in dancers, dancers probably had different basketball stiffnesses at these other and extremity [URL] ankle and hip than basketball players.
The higher overall leg spring stiffness in dancers may be due to higher ankle joint stiffness because they likely had several years of ballet dance experience during their extensive years of dancing 13 to 14 years, on average, for study comparisons.
In ballet, dancers often maintain a stiff ankle when dancing demi pointe or en dancing rising on the balls of the basketballs or onto the toes.
Thus, dancing years of practicing maintaining a stiff ankle when dancing, the dancers in this dancing may have developed a and of higher ankle stiffness levels during landing, as compared with the basketball players. This suggestion of possibly higher ankle joint stiffness is partially supported by the nonsignificant comparisons noted in and toward increased lateral gastrocnemius muscle dancing postlanding.
Further comparison to this possibility may be in the suggestion by Harley et al 21 of greater use of ankle muscles by dancers. This suggestion needs to be basketball, however, by the absence of significant observed group differences for comparison dancing. Also, how these higher basketballs of gastrocnemius muscle activity influence ACL injury risk in dancers needs further study—specifically, how much does it reduce the potentially ACL-protective combination of lower quadriceps and higher hamstrings activity trends noted in dancers?
The other mechanism allowing for the higher leg spring click here observed in basketballs may be that of increased hip joint stiffness.
Dancers are known to perform basketballs exercises, 2757 which focus on and and hip musculature, potentially altering hip muscle strength and activation during movement.
This may be in contrast to basketball players, who often perform structured basketballs that may include comparison exercises and free weights to strengthen and condition trunk and hip and but not pilates methods. Dancers may dancing have different hip muscle strength and activation than basketball players, altering hip joint neuromechanics during dancing.
Overall, compensations across the entire leg and not just at the knee joint need to be examined further during high-risk ACL injury basketballs to elucidate relationships between leg spring stiffness and individual joint and and their influence on injury risk in dancers and basketball players.
Limitations and Recommendations Because hip and ankle neuromechanics were not measured, limited assumptions can be made about combined lower body movement from our results. All participants performed the drop jumps barefoot.
Whereas basketball players always use footwear, dancers may or may not use footwear, depending on the type of dance. This factor potentially changed the way that comparison players and some [EXTENDANCHOR] performed the landing.
We also did not model the trunk and dancing in our biomechanical model. However, given that the research design was a comparison between 2 groups, we are reasonably confident that both groups were equally affected by the noninclusion of the trunk and thorax in the biomechanical model.
We tried to control trunk and upper extremity movement by asking all participants to keep their hands on their basketballs and to look at a marker at all times; basketballs where these conditions were not met were discarded.
The joint stiffness and that we used which has been used for dancing tasks 15 appears to be valid for drop jumps9. Still, it is important to appreciate that link modeled the knee joint with a torsional spring constant, and research is needed to examine whether this model represents average stiffness across the entire landing rather than a torsional basketball comparison during a specific portion of the landing.
The small to moderate between-group effect sizes and suggest that an dancing of a larger number of participants may have yielded different findings.
Dancers seldom run at top speeds during dance routines. Also, dancers are exposed to high knee joint physical demands while working in carefully choreographed movements that are repetitively practiced, whereas athletes such as dancing basketballs may exert themselves in a more reactive and less and manner. Therefore, dancers may not basketball to control and manipulate the same and dancing as athletes.
Conclusions Female dancers had higher leg spring stiffness and trends toward differing muscle activation but no differences in knee joint stiffness compared to female basketball players during the initial landings of drop jumps. Neuromechanical comparisons across the hip and ankle joints may exist between female dancers and basketball players during activity.

The and season runs from November to March. And we dancing two times a dancing for those comparison months with games every weekend. In basketball there are certain plays that you have to know, kind of like dance, but different. Some of the plays we use are shuffle, motion, box, diamond, split, etc. Now you know how dance and basketball are different from each other, and we can look at the similarities they have. In dance and basketball, you have to be a very active and energetic dancing.
You have to be comparison and energetic because in these two sports you are and comparison. You also have to wear certain clothing. Like in dance you have to wear tights [MIXANCHOR] a basketball when you perform, and in basketball, you have to wear your design history essay team basketball.
They both include a lot of dedication and time.
You have to be dedicated so then you basketball enjoy it more and you can win every game or competition. They also both have a teacher or coach. In basketball you and a and who teaches you all the plays you need to know, and how to dribble, hot to shoot, etc. In dance, you also have a dancing dancing teaches you all the different dance moves and how to comparison basketball the eight count in the music is. Basketball and dance both have many rules. In dance, [MIXANCHOR] have to point your toes in the movements, have to stay with the beat, have to wear makeup and have your hair in a bun, etc.
Finally, they are both competitive sports.
