Effect of Puberty on
Effects of sports training in adolescence on growth, puberty and bone health.
training in adolescent females is important for their well-being;
indeed, it may have both positive and negative effects on some
physiological processes, as growth, reproductive axis and bone health.
Adequate physical activity likely exerts neither a positive nor a
negative effect on growth. By contrast, intensive training and
insufficient diet may have a negative influence on growth, probably due
to energy deficiency and impairment of the growth hormone-insulin-like
growth factor-I axis; net long term-effects of such alterations remain
to be established.
Adolescents who perform regular athletic training
present with normal or slightly advanced sexual maturation, because
increased strength and power associated with earlier maturation
advantage them. However, intensive training and inadequate energy
intake may induce delayed menarche and menstrual dysfunctions.
consequent hypoestrogenism, in association with the nutritional
deficiencies, may affect bone health. On the contrary, regular physical
activity increases the amount of bone mass gained during childhood and
adolescence mainly at the bone sites which are trained.
Since the number of adolescent females involved in strenuous sports from an early age is increasing, physicians must be aware of such effects, explain to girls and their parents the 'right' sports training and appropriate dietary regimens, and recognize problems due to excessive training as soon as possible. These issues should not be a cause of lesser involvement in athletic participation of young people.
Puberty Can't Be Ignored
Sure, most of us recognize the telltale signs of puberty — hair growth in new places, menstruation, body odor, lower voice in boys, breast growth in girls, etc. But we may not fully comprehend the science behind all of these changes. Here's a quick look at how it works.
Puberty usually begins after a girl's 8th birthday or after a boy turns 9 or 10, when an area of the brain called the hypothalamus starts to release gonadotropin hormone (GnRH). When GnRH travels to the pituitary gland (a small gland under the brain that produces hormones that control other glands throughout the body), it releases two more puberty hormones — luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
The physical, emotional, and mental changes that happen next depends on gender:
Sports and Recreational Activities are Affected by Puberty
The changes experienced by adolescents affect a child's relationships with their parents, siblings, social groups, school peer groups, employees and the boss at a part time job, and even participation at church and other groups such as sports.
Preadolescent girls may have happily played on a soccer or softball team in grade school, now in middle school sports are “no longer fun” and she seems obsessed with her looks instead. She isn't alone: Research from Women's Sports Foundation reports that beginning in middle school and through high school, girls experience a 23 percent decline in sports participation, compared to 10 percent for boys. In addition, a report released by the Girl Scout Research Institute reported that 40 percent of girls age 11 to 17 whom they surveyed said they don’t participate in sports because they don’t feel skilled or competent, and 23 percent don’t participate because they feel they don’t look good doing so.

Dan Saferstein, a psychologist from
Michigan, and author of Win or Lose: A Guide to
Sports Parenting, "says parents need to step
back from being so emotionally vested in their child’s sports
performance. “It’s important not to get too caught up in trying to get
your child to be a better athlete. Some parents think they are going to
be the variable in getting their kids to excel. Be supportive as you
would be in anything."
Sports and Recreational Injuries - Kid Emergencies.com
Involvement in sports and recreational activities are important for children and teenagers. ... Prior to the onset of puberty, the risk of sports-related injury between boys and girls is the same, as they are approximately the same size and weight. During puberty, boys are injured more frequently and severely than girls. Girls more commonly suffer from a torn knee ligament called the ACL, or anterior cruciate ligament, common in any sport with a lot of twisting, jumping or pivoting — basketball, soccer, football, volleyball, skiing.
