Modern technology in service of physical
activity – how can we benefit from it?

Physical (in) activity
as a cause of major health problems
Physiological (d)effects:
 Cardio-respiratory fitness (coronary heart disease, cardiac failure)
 Metabolic system/syndrome functioning (fat free mass, overweight, obesity)
 Osteoporosis (low bone mass, fractures, falls, back pains)
 Nervous system (co-ordination, stress coping)
But also socio-cultural (d)effects:




Quality of life (specially in elderly stages)
Sense of coherence (meaningfulness, comprehensibility, manageability)
Social contacts
General social acceptance and need for physical activity
Physical activity - findings
Early physical activity experience should provide



gross-motor activities that involve postural control,
coordination of movements, and locomotion – crawling,
creeping, body rolling, and jumping
moderate and vigorous intensity gross-motor activity
provide the brain with its chief energy source, glucose.
These activities increase blood flow, which feeds the brain
and enhances neuronal connectivity during the critical
period.
To help develop the brain before it is too late
Studies on neglected children, who had
been deprived of physical and mental
stimulation, found that parts of their brain
were underdeveloped and 20-30% smaller
than most children their age.

But effects of PE/school sport are misserable

Obese pupils more often skip PE classes, often
declare they dislike PE
[Fenczyn, Szmigiel 2006; Oblacińska, Jodkowska 2007]

Obese girls two times more frequently have (all
sort of) leaves and excuses not to take part in
PE than their able friends [Oblacińska, Tabak 2006]

Lower rate of frequency in extracurricular and
out of school activities of obese and those with
profound learning difficulties [Oblacińska, Tabak 2006]
Obesity in Polish children
Obesity is an international problem
Social consequences
 Obesity
in childhood is transferred into adulthood
(Clarke, Lauer 1993; Guo et al 2002; Must, Strauss 1999; Power et al 1997;
Reilly et al. 2003; Serdula et al. 1993)
morbidity and mortality rates – due to heart
and metabolic diseases (Must et al. 1992)
 Higher
 Low
self-esteem, negative self-perception, lower
quality of life, limited social contacts
(Kochman i Czerwionka – Szafarska 2004, Radoszewska 1995)

Obese and overweight more often commit small
crimes
(Berg i współ. 2005; Janssen i współ. 2004; Oblacińska, Jodkowska 2007)
Some data on using IT and on-line activities
-
An avarage pupil in the US school spends 13 000 hours, 25 000 in front of TV. Pupil
would see 8000 murders and 100 000 acts of violence in which 73% an offender
gets away of the punishment, in 58% showed as if there were no negative
consequences, or no pain of other poeple.

- People at the age of 50 not using the Internet at all – five days access to the Internet
causes activation of the same neuron loops as in the brains of those using the
Internet daily.

University of California research findings:
-
Mirror neuron loops are activated when we do a motor movement ourself
and when we see others performing a motor movement
but they are not activated when movement acts are observed on a TV screen these situations lack social interactions (magnetic resonans examination)

Glued to Your Cell Phone? Research Suggests It
May Reduce Your Physical Activity and Fitness




More than 300 college students from the Midwest were
surveyed on their cell phone usage and activity level.
The researchers’ results showed that high cell phone use was
associated with low cardiorespiratory fitness.
Students who were the least fit were those who spent large
amounts of time on their cell phones – as much as 14 hours
per day.
The most fit students were those who used the cell phone the
least – around 90 minutes per day.

Technological methods and their practical use for
supporting the individual physical fitness of
adolescents in school and leisure time sport
A mobile device gathers biomechanical and/or physiological
parameter values on the spot and sends it to a server component for
further analyses. The classification of the data and generation of
(immediate) feedback is based on expert knowledge (sport scientists)
and can be adapted sports specifically.

Real dance or a dance mat
Dance - number of steps and calories
Modern device – accelometers.
Can they be of any help in increasing PA ?
Modern on-line PA program registrators
You know when, where, how
Absorbing new IT for educational purposes?
Dengers
Advantages

1.Technology as an atractive but just a tool
1.Technology as a goal
2. New pedagogical environment
2. New safety hazards
3. Pupils usually know more then teachers
3. Danger of been out-dated
4. Assassment on achieving the lesson objectives
with the use of IT
4. Assassment reduced to how technology
device was used
5. Instant feedback from the screen and pupils
can do it alone learning proper technique
5. No social intaraction – potential problems
with futher social relations in school or
work
6.
Physical education and orientation of
physical fitness components

health-related
- cardiovascular endurance
- flexibility
- muscular endurance
- muscular strength
- body composition
vs.
performance-related
- agility
- balance
- co-ordination
- power
- reaction time/speed
