Strength training in hypoxia has been shown to enhance hypertrophy and function of skeletal muscle, however, the effects of plyometric training in hypoxia is relatively unknown. Therefore, this study aimed to examine the effects of plyometric training in hypoxia compared to normoxia on body composition, sprint and jump parameters. Twenty-three male physical education students (20.4 +/- 2.0 years, mean +/- SD) participated in the study and were divided into a plyometric training in hypoxia (PTH, n=8), plyometric training in normoxia (PTN, n=7) or control group (C, n=8). The PTH group trained in normobaric hypoxia (approximately 3536 m) 3 days/week for 8 weeks, while the PTN trained in normoxia. PTH induced significant improvements from baseline to post-testing in countermovement-jump (37.8 +/- 6.7 cm, 43.4 +/- 5.0 cm, p<0.05), squat-jump (35.4 +/- 6.2 cm, 41.1 +/- 5.7 cm, p<0.05), drop-jump height (32.8 +/- 6 cm, 38.1 +/- 6 cm, p<0.05) and 20-m sprint performance (3257.1 +/- 109.5 ms, 3145.8 +/- 83.6 ms, p<0.05); whereas PTN produced significant improvement only in countermovement-jump (37.3 +/- 4.8 cm, 40.5 +/- 4.5 cm, p<0.05) and 20-m sprint performance (3209 . 3 +/- 76.1 ms, 3126.6 +/- 100.4 ms, p<0.05). Plyometric training under hypoxic conditions induces greater improvement in some jump measures (drop-jump and squat-jump) compared to similar training in normoxia.


The Effects of plyometric training in normobaric hypoxia on body composition, anaerobic performance, strength, and explosive power
Coşkun, Betül; Koçak, Mehmet Settar; Department of Physical Education and Sports (2019)
Purpose of this study is comparing the effects of plyometric training in hypoxia and normoxia on body composition, jump and sprint performance, Wingate anaerobic power and isokinetic strength test results. 23 male volunteers from physical education students (Age=20.39±2.02) participated and were randomly divided into Plyometric training in Hypoxia (PTH)(n=8), Plyometric training in Normoxia (PTN)(n=7) and Control (n=8) groups. While PTH performed plyometric training under normobaric hypoxic conditions (3.53...
Vibration analysis in the diagnosis of bone mineral density in healthy and osteopenic radius bone and its correlation to muscle strength
Özdurak, Rabia Hürrem; Korkusuz, Feza; Department of Physical Education and Sports (2004)
Muscle strength is assumed to be closely related with BMD, the so called determinant of bone strength, however, new methods for bone strength measurement are arising. The purpose of this study was to determine the relationship between bone mineral density (BMD), muscle strength and natural frequency of the radius in the dominant and non-dominant arm in healthy and osteopenic individuals aged between 50-70 years. Sixty sedentary male (thirty healthy and thirty osteopenic) participated this study. Bone minera...

Pilates exercise positively affects balance, reaction time, muscle strength, number of falls and psychological parameters in 65+ years old women
Babayiğit İrez, Gönül; Korkusuz, Feza; Department of Physical Education and Sports (2009)
Physical changes such as impairment flexibility, balance, muscle strength and reaction time occur with aging. Regular lifetime physical activity appears to delay these factors. The purpose of this study was to determine if 12 weeks Pilates exercise could improve dynamic balance, reaction time, flexibility, muscle strength, bone density and quality of life in 65+ years old women and to investigate the changes of these parameters in a year follow up. Thirty out of a hundred women living in a Residential House...
Serum cartilage oligomeric matrix protein accumulation decreases significantly after 12 weeks of running but not swimming and cycling training - A randomised controlled trial
Celik, Ozgur; SALCI, YAŞAR; Ak, Emre; KALACI, AYDINER; Korkusuz, Feza (2013-01-01)
Background: Acute effects of physical exercise on the deformational behaviour of articular cartilage and changes in cartilage oligomeric matrix protein (COMP) are definite. However, conclusive positive effects of fitness exercise on functional adaptation of articular cartilage have not been proved.
