BACKGROUND Most studies on physical fitness and detraining have been conducted on normal-weight children. Their results indicate that any gains regress to the untrained control values during the detraining period. It, therefore, seems necessary to determine how detraining affects the different fitness parameters in obese children. The aim of the present study was to evaluate the effects of detr...

Skeletal muscle primarily relies on carbohydrate (CHO) for energy provision during high-intensity exercise. We hypothesized that sprint interval training (SIT), or repeated sessions of high-intensity exercise, would induce rapid changes in transport proteins associated with CHO metabolism, whereas changes in skeletal muscle fatty acid transporters would occur more slowly. Eight active men (22 +...

OBJECTIVE To investigate adaptive changes in bone and muscle parameters in the paralysed limbs after detraining or reduced functional electrical stimulation (FES) induced cycling following high-volume FES-cycling in chronic spinal cord injury. SUBJECTS Five subjects with motor-sensory complete spinal cord injury (age 38.6 years, lesion duration 11.4 years) were included. Four subjects stopped...

BACKGROUND We examined the effects of detraining after blood flow-restricted (BFR) low-load elastic band training on muscle size and arterial stiffness in older women. FINDINGS Fourteen women were divided into BFR training (BFR-T) or non-BFR training (CON-T). Each group participated in 12 weeks of arm curl and press down training using an elastic band either with (BFR-T) or without BFR (CON-T...

In the current investigation we tested how swimming training (T) (8 week, 5 times/week, 2 h/day), and detraining (DT) affects brain functions and oxidative stress markers in rat brain. The free radical concentration, measured by electron paramagnetic resonance, decreased in brain of T and DT rats compared to controls (C). The level of brain-derived neurotrophic factor (BDNF) increased as a resu...

The present study was performed to clarify the effects of intermittent exposure to an altitude of 4,500 m with endurance training and detraining on ventilatory chemosensitivity. Seven subjects (sea-level group) trained at sea level at 70% maximal oxygen uptake (VO2 max) for 30 min/day, 5 days/wk for 2 wk, whereas the other seven subjects (altitude group) trained at the same relative intensity (...
